Wind driven surface currents (such as the Gulf Stream) head polewards from the equatorial Atlantic Ocean, cooling all the while and eventually sinking at high latitudes (forming North Atlantic Deep Water). This dense water then flows downhill into the deep water basins, only resurfacing in the northeast Pacific Ocean 1200 years later. Extensive mixing therefore takes place between the ocean basins, reducing differences between them and making the Earth's ocean a global system. On their journey, the water masses piggyback both energy (in the form of heat) and matter (solids, dissolved substances and gases) around the globe. As such, the state of the circulation has a large impact on the climate of our planet.  It's also called thermohaline circulation

Look up "disk accretion", a popular theory about the formation of our solar system.  This theory explains that as the cloud of dust and gas that formed our system was condensing, it's rotational motion caused an effect similar to centrifugal force which flattened the spinning cloud into a spinning disk.  \n\nI should note that the system isn't exactly flat, a couple of the outer planets have taken on orbits that are quite askew to the disk that the inner planets are aligned with.\n\nThe following web site has some simplified explanations of solar system formation:\nhttp://www.windows.ucar.edu/tour/link=/our_solar_system/formation.html\n\nand more in-depth info at:\nhttp://www.dtm.ciw.edu/akir/Seminar/seminar.html

OK, here goes---no chemical formulas--look that up in your chemistry book.\n\nLead is mined.  The ore comes out of the mine as a Lead Oxide.  Chunks of ore range from about the size of a loaf of bread on down.  Ore goes through jaw crushers to reduce in size.  Golfball size ore goes through a rod mill. (Large revolving drum full of steel rods)  Comes out pea sized.  Ore goes into a ball mill. (Large revolving drum full of steel balls)  Comes out the size and consistency of talcum powder)   The ore/water mixture is called a slurry.  The slurry comes out of the ball mill and goes into flotation chambers where a mixture of water and foaming agents are being agitated.  The lead particles in the slurry attach themselves to the bubbles created by the foaming agent.  They rise to the top of the tank where the foam is scraped off by paddles.  Waste rock called tailings is pumped in a slurry form to a disposal site.  The lead bubble foam is transported to a dryer.  The dryer removes excess water and leaves the final product of the mine and mill--lead concentrate.  (lead oxide)\n\nThe concentrate is hauled to the smelter.  If it was put into the furnace in its current state it would go right up the chimney---the lead is the consistency of talcum powder.  In order to melt the lead, we have to hold it in place long enough to melt so that it doesn't all just blow out the chimney.  This is done by a process called sintering.  Lead concentrate is added to crushed limestone, coke and other chemical reagents.  It is then run through the sintering machine.  The sintering machine roasts the mixture for 20 minutes and when the sinter comes out the end of the machine it resembles the klinkers that you'll see come out of an old coal fired furnace.  The roasting process causes all the ingredients to mold together into a solid chunk---called sinter.  The sinter comes out of the machine in huge chunks---as big as a car---and is run through a crusher to break it up into manageable size--about the size of a basketball on down.  The sinter goes into a storage bin.\n\nNow, its time for the furnace.  The sinter is mixed with more powdered limestone, iron ore, coke, coke breeze, lead scraps from spills.  This mixture is fed into a top feed furnace.  As the mixture falls down into the bottom of the furnace it encounters the fire.  Pure oxygen is pumped into the furnace, feeding the fire.  The coke and coke breeze burn creating enormous amounts of heat.  The sinter holds the lead in place long enough for it to melt and flow into the bottom of the furnace.  The sinter is then consumed by the fire as its remaining ingredients are partially cooked coke.  When the bottom of the furnace fills up with molten lead, it is tapped by the furnaceman.  The furnaceman will drain off a huge kettle full of molten lead.  Once the kettle is full the furnaceman will shut off the flow.  An overhead crane picks up the kettle and takes it over to the refinery area.\n\nA lot of sulfur containing compounds are generated as by-products of the smelting process.  At one plant I worked at they had an acid plant on site.  By scrubbing the furnace's exhaust gasses, they removed most of the SO2 from the exhaust.  The SO2 was then sent to the acid plant where a chemical reaction took place and the SO2 was changed to sulfuric acid---H2SO4.  The acid plant would produce a rail car full of 98% pure sufuric acid every day.\n\nThe scrubbed exhaust gasses went into another scrubbing device called the 'baghouse'.  This was a huge four story building about the size of a city block.  Every floor had dozens of rooms on it.  Each room was filled with bags that stretched from the ceiling of the room to the floor.  This bags were made of cloth---they were filter bags.  The exhaust gasses passed through these bags and the most minute particles were filtered out. The remaining exhaust gasses went up the chimney.\n\nWhoa--that brought back memories!  Believe me, you haven't lived t

We think that the planets all formed pretty much at the same time. However the sun probably formed first. The leftover gas and dust remained in a disk around the sun. In this disk, stuff began to clump and form "planetesimals" (pronounced pla-ne-TE-si-mals). These are small rocky bodies, something like asteroids. They crashed into each other and eventually formed the inner planets. At the same time, planetesimals formed the cores of the outer planets Jupiter and Saturn. Because of their strong gravity, they swept up a lot of gas. Uranus and Neptune did this too, but there was less gas around because Jupiter and Saturn got it first. The asteroid belt may be left-over planetesimals that never formed a planet because Jupiter's strong gravity nearby kept it from forming.

Magnetization of materials\n\nFerromagnetic materials can be magnetized in the following ways:\n\n* Placing the item in an external magnetic field will result in the item retaining some of the magnetism on removal. Vibration has been shown to increase the effect. Ferrous materials aligned with the earth's magnetic field and which are subject to vibration (e.g. frame of a conveyor) have been shown to acquire significant residual magnetism.\n    \n* Placing the item in a solenoid with a direct current passing through it.\n    \n* Stroking - An existing magnet is moved from one end of the item to the other repeatedly in the same direction.\n    \n* Placing a steel bar in a magnetic field, then heating it to a high temperature and then finally hammering it as it cools. This can be done by laying the magnet in a North-South direction in the Earth's magnetic field. In this case, the magnet is not very strong but the effect is permanent.\nMagnetization of materials\n\nFerromagnetic materials can be magnetized in the following ways:\n\n* Placing the item in an external magnetic field will result in the item retaining some of the magnetism on removal.

it comes from oil the polythene granule "like small peas" or polymer is mixed with various linears and additives such as anti satic, anti slip or slip and master batches to give it colour or strength.then the granule is heat as it goes through a screw and is heat in gradual stages from 0-230c ish depends on polymer type.then the molten polymer is pushed thorough a die from the screw and pull up to a set of rollers "nip" then compressed air is blown into the die to blow the bubble out to the size required. the speed of the rollers is increased to get the thickness "gauge" and then it is put through a set of winders and put on a reel.

Is this really a homework question???  Its terrible!  Did you transcribe it correctly?\n\nI *think* the point of the question is to lead you to understand that glaciers deposit moraines at their terminus.  Glaciers are like conveyor belts--they move rocks and sand/gravel/silt/etc from their origin point to a point farther down the glacier.  The farthest point to which a glacier reaches is called its 'terminal position.'  Therefore, the moraine farthest from where the glacier originates is the 'terminal moraine.'  However (to complicate things), glaciers like to "stop" and "start" (not literally!)--so they deposit moraines whenever the terminus of the glacier sits in one position for awhile.  These are called recessional moraines--they are left as the glacier is retreating.  You will never see advancing moraines (not even sure that's a real term)--they get bulldozed by the glacier as it advances.\n\nBOTH types of glaciers (alpine and continental) deposit material at their terminus.  The landforms most common at the terminus of a glacier are moraines (or end moraines).

Tubular Drag conveyors are used to convey a wide range of powders and bulk solids in the food, chemical, pharmaceutical, mining and wastewater treatment industries. They are an excellent choice for dependable 24/7 operations which require low segregation and/or degradation; complete enclosure for dust control; the handling of high moisture content materials, difficult to handle abrasive materials or ones which may tend to pack / smear; and in situations which may require multiple inlets and/or outlets. They are extremely flexible in plant layouts and integrate well with existing equipment. Bulk materials are conveyed between the sealed-pin chain flights, at virtually any angle, for distances of up to 85 feet vertically, and more than 200 feet horizontally, depending on material bulk densities and required capacity. Flights can be specified in a choice of several materials (depending upon the application) and are easily replaceable. Models ranges in size from 3-inch diameter up to 12-inch with pipe construction of schedule 10, 40, 80, or Abrasion Resistant Lining. Capacities can reach up to 60 cubic feet per minute, with a maximum conveyor speed of 185 feet per minute, for straight run configurations.

Some are moving away from each other (i.e. their separation is increasing), such as Africa and South America. Some are moving closer together, like North America and Asia. Some places continents or pieces of continents are moving past each other, like in the Pacific Northwest, or in the Afar Triangle in Somalia. Some places are expanding, like Iceland. \n\nThere are lots of ways to measure this, but the first clue that something was going on came from looking at the shapes of coastlines. Look at the coastlines of western Africa and eastern South America. They look like they could fit together, like a puzzle. The rocks match each other on both continents too, as if the two continents were once fit together. \n\nHowever, the big clue that something was going on came from magnetic stripes on the sea floor. As new basalt forms in the middle of the Atlantic, and some other oceans, it pushes out from the central mid-ocean ridge, and cools. When it cools, it sets, taking on a magnetization aligned with the magnetic field of the earth at that moment. However, the earth's magnetic field flips every few thousand years (just like the Sun's does, every 11.5 years or so). This creates a record of magnetic stripes on the sea floor that alternate polarity. When the scientists Vine and Mathews saw this, they knew they had proved that plate tectonics existed, and that the continents were moving (sometimes away from each other, and sometimes towards each other or past each other)

Probably silicone and iron.   It's a friggin big rock.   Hollow it out a bit; near the center the gravity is probably near earths gravity.

Earth and the other planets were formed from a giant cloud of gas and dust revolving around the primitive sun. As in any other moving fluid, local whirlpools kept appearing and disappearing all the time. \nAs the cloud started to cool, local perturbations caused density variations : some whirlpools got lumpier than others, just as in a bowl of porridge when it cools off. They thus grew more stable and accumulated more matter because of their increasing gravity. On further cooling, these separated out as planets, molten globes of matter still spinning furiously.\nEven when the planets solidified at last, they retained a part of their original spin. That's why the Earth and the other planets are still spinning around their axes. That's what, thankfully for us, creates days and nights.

It was formed from the ring of dust and debris orbiting the sun when the sun gained enough mass to start the fusion process.  It was formed in the same way and at the same time as all the other planets.

The gravity is concentrated in the center of the matter and pulls all the edges with the same strength thus creating a sphere

maybe take a different approach and look at how a simple chain can be formed from nothing. what are the odds of that happening. take a spin on the WWW to find out.

First of all the world is not round it is an oblique sphereoid (basically a double ended pear shape.)\n\nThe force of gravity generated by the molten core of the planet acts in all directions equally at any one point in the planet.  This attracted the material from space that formed earth following the Big Bang.  This would form a spherical object.\n\nThe rotation of the planet complicates thia as the equator is rotating faster than parts of the Earth that are further away from the equator, the poles rotate the slowest.  This disparity causes greater centripidal forces to be experienced at the equator than at the poles so the earth bulges out at the centre.
