The middle layer of the earth is called the...?

middle layer would be mantle, center would be core.

All things are attracted to the center of the earth regardless of their orientation to it.So you could dig "down" into the earth but once you passed through the center you would start digging "up" because gravity would be pulling you back to the center which is behind and "below" you

Earth: \nthe fragmental material composing part of the surface of the globe; especially: cultivable soil; or\nareas of land as distinguished from sea and air; or\nthe planet on which we live that is third in order from the sun.\n\nIt depends how you use it, really...

the earth consist of 3 layers\n\n1) crust(lithosphere)\n2)mantle\n3)core (outer core n inner core)\n\na) core(innermost) is made up of FE-NI ALLOY\n     \n     inner core is solid and 650km depth\n\n     outer core is liqiuid & 2100 in depth\n\n\n b)mantle is about 2900 km thick\n\n\nc) crust thickness varies frm 10-50 km...it is made up  of  three types of rock

The crust but more specifically the lithospheric plates.\n\nThe lithosphere is divided into 7 major plates and about 7 minor ones. The major ones contain the continents.\n\nThese plates move in response to the convection of molten material in the mantle. As the molten rock circulates, it pulls lithospheric plates along like they were on a conveyor belt.\n\nThe crust floats atop the molten rock below b/c it is less dense.

The crust and mantle are generally solid.  The inner and outer core are molten rock and metal...very dense, but still liquid.

The mesosphere (from the Greek words mesos = middle and sphaira = ball) is the layer of the Earth's atmosphere that is directly above the stratosphere and directly below the thermosphere. The mesosphere is located about 50-80/85km above Earth's surface. Within this layer, temperature decreases with increasing altitude. The main dynamical features in this region are the atmospheric tides which are driven by momentum propogating upwards from the lower atmosphere and extend into the lower thermosphere

It is a divergent plate boundary found running down the middle of the Atlantic Ocean. Hence the name "Mid Atlantic Ridge".\n\nThis is where two lithospheric plates are moving apart from each other.\n\nWhere they spread apart, new continental crust is being created. It is said that the US & the UK move about 1 - 2 inches apart every year. The US is getting further from Europe all the time!

i think u mean tectonic plate.  tectonic plates are the sections the outer layer of earth is divided into.  there is pressure between the plates, so they sometimes slip and slide and that's how we get earthquakes.  tectonic plates are different sizes.  some only carry one island while others can have a whole continent and part of an ocean!  as for what platonic plates are, i've never heard of them, so i'm sure you mean tectonic plate.

A molten core of super heated metal (believed to be Iron and Nickel) is spinning at the center of the earth faster than the exterior of the earth is rotating.\n\nCharged Particles create a magnetic field when they move.

The actual K/T boundary layer lies between the cretaceous and tertiary sediments in the sedimentary rock deposits. According to Alan R. Hildebrand (1992), the layer is similar all around the world and has an inner structure of two layers. The upper layer is known as the "Fireball layer" and is in average 3mm thick. Its thickness is the same around the globe, and thus it must have been dispersed quite quickly (within 2-3 months). It represents 1500 cubic kilometres of debris deposited globally. The lower layer, named the "Ejecta layer", averages about 2cm in thickness. The layers are mostly made of clay, with some soot in the upper parts.

Dudes, the eqeator or prime meridian do NOT go THROUGH the center of the earth AT ALL!\n\nThe answer is Axis, duh.

mantle\nThe Mantle. It is divided into two parts. The upper portion, which is called the Asthenosphere, is a plastic like fluid. This is where the mantle convection currents occur. The rest of the mantle is made up of dense rock. The mantle is the thickest layer. Approximately 2900 km thick

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).

About 1,800 miles beneath the surface, Earth's internal structure changes abruptly where the solid rock of the mantle meets the swirling molten iron of the outer core. \nBut the boundary between the core and the mantle may not be as sharply defined as scientists once thought. By analyzing earthquake waves that bounce off the core-mantle boundary, researchers have found evidence of a thin zone where the outermost core is more solid than fluid.\n\nThe existence of such "core-rigidity zones" -- small patches of rigid material within the fluid outer core -- has been suggested before, but this report marks the first time scientists have detected one.
