a?Inside the Eartha

Crust The thin and solid outermost layer of the earth above the mantle
Mantle The layer of rock between the earths crusts and core
Core The central part of earth below the mantle
Lithosphere the rigid outer part of the earth, consisting of the crust and upper mantle.
Asthenosphere the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur
Mesosphere Beneath the asthenosphere is the strong lower part of the mantle called the Mesosphere the Mesosphere extends from the bottom of the earths core
Outer core The Earths core is divided into two parts-the outer core and the inner core the outer core is the liquid layer of the Earths core that lies beneath the mantle and surrounds the inner core
Tectonic plates A block of lithosphere that consist of the crust and the rigid outermost part of the mantle
Continental drift The hypothesis that states that the continents once formed a singular landmass broke up and drifted to their present locations
Sea-floor spreading The process by which new organic lithosphere forms as magma rises toward the surface and solidifies
Plate tectonics The theory that explains how large pieces of the Earths outermost layer called tectonic plates move and Change shape
Convergent boundary The boundary formed by the collision of two lithospheric plates
Divergent boundary The boundary between two tectonic plates that are moving away from each other
Transform boundary
The boundary between tectonic plates that are sliding past each other horizontally
Comprehension Stress that occurs when forces act to squeeze an object
Tension Stress that occurs when forces act to stretch an object
Folding The bending of rock layers due to stress
Fault A break in a body of rock along which one block slides relative to another
Uplift The rising of regions of the Earths crust to higher elevations
Subsidence The sinking of regions of the Earths crust to lower elevations
