Earth's outer layer: the coolest and least dense layer of Earth See also core, and mantle

The layer of Earth beneath the crust. it is about 2,900 km (1,800 mi) thick, and makes up about 83 percent of Earth's interior,

Earth's outer core is a fluid layer about 2,260 km (1,400 mi) thick, composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle.

The inner core is the solid, innermost layer of Earth, acting as a, "planet within a planet" at the planet's center

The distance North or South of the equator measured in degrees.

The distance East or West of the prime meridian in Greenwich, England; measured in degrees.

A mountain- like landform that develops when tectonic plates move apart or separate and a new ocean lithosphere forms

A process by which new Sea-Floor is formed from the magma rising from Earth's diverg

Location where two tectonic plates meet and are moving away from each other

Location where two tectonic plates meet and are moving toward each other.

Location where two tectonic plates meet and slide past each other (without creating a new landform)

The process by which one plate of the lithosphere sinks and slides under another

Long, deep formation on the ocean floor that develops where two tectonic plates are moving toward each other, and one is moving under the other.

A piece of Earth's crust that, according to plate tectonics, is pushed by movement in the aesthenophere

The cool, solid outer shell of Earth. It consists of the crust and the rigid uppermost part of the mantle and is broken up into segments, or plates.

The breakage of rock into two or more pieces.

The ability of rock to be stretched and then return to its original position once the stress has been removed.

The amount of force being applied to a rock or surface.

Change in volume, size, or shape that results from stress.

A place where pieces of the broken lithosphere meet. Boundary types include convergent, divergent, and transform

Crust that contains mostly land, ranging from 15 to 70 km (9 to 43 miles) thick

Crust that lies beneath the ocean, ranging from 5 to 10 km (3 to 6 mi) thick

A force that opposes the motion of objects, which are in contact.

The valley formed by a diverging plate boundary.
