The winds cause waves on the surface of the ocean (and on lakes). The wind transfers some of its energy to the water, through friction between the air molecules and the water molecules. Stronger winds (like storm surges) cause larger waves. You can make your own miniature waves by blowing across the surface of a pan of water. \nWaves of water do not move horizontally, they only move up and down (a wave does not represent a flow of water). You can see a demonstration of this by watching a floating buoy bob up and down with a wave; it does not, however, move horizontally with the wave. \n\nTsunamis (sometimes called tidal waves) are different from surface waves; they are usually caused by underwater earthquakes, volcanic eruptions, or landslides.\n\n\nI hope this helps....\n\nDon

It is basically huge waves formed in a sea or ocean because of a displacement of water by an earthquake, underwater volcano,....

EARTHQUAKE WAVES\n\nEarthquakes produce three kinds of shock waves.\n\nBody waves move through the Earth from the focus.\n\nSurface waves travel in the outer layers of the Earth.\n\nFree oscillations are the movement of the entire Earth as the result of the largest earthquakes.\n\nBody waves are composed of two types of waves.\n\nP or primary waves are waves where the rock is push back and forth through compression.\n\nS or secondary waves are waves where the rock is pulled sideways.\n\nP and S waves have been used to understand the composition of the interior of the Earth.\n\nThese waves take different tracks and velocities depending on the density and elasticity of the material they are passing through.\n\nS waves do not pass through liquids so the inability of the the outer core to carry S waves would suggest the presence of a liquid core.\n\nAt the Earths surface earthquake waves can sometimes be seen causing the surface to oscillate.\n\nIn oceans the wave energy can be transferred into the water to form tsunami.

1) Evaporation.  The world's largest ocean is on one side of the peninsula, Puget Sound is on the other.  More water evaporates from the ocean that from the sound.\n\n2)  Elevation.  The water from the ocean side of the peninsula does not make it to the sound side of the peninsula because of elevation.  As elevation rises, it forces clouds to go up where the air can hold less moisture.  The clouds then lose their moisture as precipitation while getting over the hump.  The moisture never makes it eastward.

This is what causes a surface current. \nAs winds blow across the ocean, there is friction between the wind and the water. Some of the energy of the wind is transferred to the water to make waves which travel across the surface of the ocean and some of the energy is transferred into surface currents.\nWhen currents run into something, like a continent, they must change direction. The current must turn right or left to form boundary currents or flow below the surface of the ocean to form a subsurface current.

If you get into folk stories and mythology you will see that almost every culture has a story explaining how the oceans became salty. The answer is really very simple. Salt in the ocean comes from rocks on land. Here's how it works:\n\nThe rain that falls on the land contains some dissolved carbon dioxide from the surrounding air. This causes the rainwater to be slightly acidic due to carbonic acid (which forms from carbon dioxide and water). The rain erodes the rock and the acid breaks down the rocks and carries it along in a dissolved state as ions. The ions in the runoff are carried to the streams and rivers to the ocean. Many of the dissolved ions are used by organisms in the ocean and are removed from the water. Others are not used up and are left for long periods of time where their concentrations increase over time.\n\nThe two ions that are present most often in seawater are are chloride and sodium. These two make up over 90% of all dissolved ions in seawater. By the way, the concentration of salt in seawater (salinity) is about 35 parts per thousand. In other words, about 35 of 1,000 (3.5%) of the weight of seawater comes from the dissolved salts; in a cubic mile of seawater the weight of the salt, as sodium chloride, would be about 120 million tons. And, just so you don't think seawater is worthless, a cubic mile of it also can contain up to 25 tons of gold and up to 45 tons of silver! Before you go out and try alchemy on seawater, though, just think about how big a cubic mile is.\n\nBy some estimates, if the salt in the ocean could be removed and spread evenly over the Earth’s land surface it would form a layer more than 500 feet (166 m) thick, about the height of a 40-story office building.

According to answers.com\nhttp://www.answers.com/tornados%20\n\n"Tornadoes develop from severe thunderstorms, usually spawned from squall lines and supercell thunderstorms, though they sometimes happen as a result of a hurricane. They are believed to be produced when cool air overrides a layer of warm air, forcing the warm air to rise rapidly, though tornadoes over water (waterspouts) frequently are observed forming in the absence of convection or apparent strong surface temperature differences. Tornadoes, lightning, and sometimes hail are associated with thunderstorms. Many tornadoes appear at the tail end of mesocyclones. On weather radar screens, a characteristic "hook echo" marks the area where tornadoes are likely to exist."\n\nThe reference will give good idea for how do tornados form

Oceanic crust is fundamentaly different from Continental because of its origin.  Oceanic crust is formed as the continents move apart and new 'material' is forced between the plates.  You may have seen the video of lava being extruded at the bottom of the ocean 'toothpaste style'.  This forms round lumps of 'pillow lava' which have no crystals (because it cooled very quickly the crystals don't have time to form).  Below this you'll see the same material (chemically) but which forms columns of basalt (like Giant's causeway in Ireland) as it cooled slower.  Below this is the layered basalts which will form a much more massive block of basalt.  Below this is peridotite.\nChemically speaking oceanic material is basaltic whereas continental is granitic.\nContinental volcanic rocks are a lot less systematic in structure as they just intrude through thick layers of other material although they'll generally have larger crystals and will be lighter in colour.  \nBecause of their increased silica content they're more explosive and so this will be seen by the steeper sides of the volcanoes, pumice (solidified ash), etc.

Seismic Waves are the different waves that travel through the earth surface from an earthquake.  There are 2 major waves or movements observed on the surface.\n1.  P waves (compression waves) move the surface form side to side and create cavities in the ground.\n2.  S waves (shear waves) move the surface up & down creating ridges and cliffs in the surface.\n\nBS Geology Degree

Let me start saying that I'm not making up this answer:\n\nSea foam is made of air bubbles separated by a film of liquid. Air bubbles in fresh water unite, while air bubbles in salt water bounce off of each other. When these air bubbles rise to the surface in the ocean, they burst and release salt spray into the air. It is believed that most of the airborne salt comes from the bursting of bubbles.

Cumulous clouds are formed by means of convection when warm air rises from the surface and condenses into a cloud.  The air will continue to rise until it reaches a level of equilibrium. There are many factors that determine the life cycle of the cumulus.  I would suggest you contact a meteorology department at a local university and talk to someone familiar with cloud physics.

A low pressure system occurs in the air above the sea surface. It is where warmer, lighter air is rising. A high pressure system forms where cooler, drier, heavier air is sinking. Winds blow from areas of high pressure towards areas of low pressure.\n\nAs warm moist air over the ocean rises above a low pressure system it cools. Once the water vapour in the air cools to a certain point it condenses to form tiny water droplets which we see as clouds. If there is enough turbulence in a cloud and the cloud is big enough the water droplets clump together until they grow large enough to fall out of the cloud as rain.\n\nIn a strong low pressure system lots of warm moist air is rising rapidly and so very big clouds can form which have a great deal of turbulence inside. These are called storm clouds. Because they hold lots of moisture and because the tiny droplets of water inside collide with each other very frequently, very large raindrops can form which fall to the ground in heavy downpours.

If you take yourself back to first principals, orographic precipitation is caused by air moving over hills and mountains.\n\nWe'll put convectional on hold for the moment.\n\nsnow may fall on seacoasts if the the temperature is cold enough.  In the UK snow on seacoasts is usually associated with northerly winds in winter.  The air is coming from a very cold place and it snows.  It snows at least as much inland. Although snow can fall on sea coasts, it is not typical.\n\nDew is condensation.  It is formed in situ. It is not precipitation at all.  Precipitation is something that falls from the sky.\n\nYou may remember daytime sea breezes and night time land breezes which are dependent on convection.  A few miles inland you can get sea breeze fronts and like other fronts, these may produce precipitation.

Oceanic crust is formed by volcanism at the mid-ocean ridges, also called spreading centers. Magma upwells from within the asthenosphere or mantle. It often does not erupt onto the sea floor but rises through complex cracks and fissures where it encounters cooler rock and sea water. Other areas actively erupt and lava flows in sheets typically less than 10 meters thick. For example, at the Juan de Fuca Ridge, the process creates about 6 meters of new crust in 100 years. Oceanic crust consists of basalt, often referred to as MORB (mid-ocean ridge basalt).

Lightning is formed by the convective processes that occur in a thunderstorm.  You'll have the warm, moist suface layer of air with the cold, dry layer of air aloft.  The natural balance of the atmosphere makes the warm air want to rise.  This gives strong updrafts of air can help create charge differences (warm humid surface air rises and cools, condenses into waterdroplets which have different charge the ice crystals in the upper atmosphere) which can cause lightning.\n\nIn a snowstorm (or winter in general) the surface layer is cold with low dewpoints (dry), so you generally won't find these updrafts and convection found in summer thunderstorms to create lightning.\n\nHowever sometimes the conditions can bring enough warmer air, moisture and instability to cause lightning and thunder.  Check out the link provided for more in depth details.\n\nThe thunder from thundersnow is not heard at very large distances, which makes it seem even rarer.  Snow absorbs a lot of the sound, so it will only be heard about a mile or two away.
