The soft layer of the mantle on which the tectonic plates move. | asthenosphere |
A layer of Earth’s surface, lying just below the crust and above the inner core. | mantle |
A block of lithosphere that consists of the crust and the rigid, outermost part of the mantle. | tectonic plate |
The bending, tilting, and breaking of Earth’s crust; the change in the shape of rock in response to stress. | deformation |
The boundary between tectonic plates that are colliding. | convergent boundary |
The boundary between two tectonic plates that are moving away from each other. | divergent boundary |
The boundary between tectonic plates that are sliding past each other horizontally. | transform boundary |
the type of stress that occurs when an object is squeezed as when two tectonic plates collide. | compression |
the amount of force per unit area that is put on a given material. | stress |
The surface along which rocks break and slide past each other. | fault |
The name of the scientist credited for developing the Theory of Continental Drift | Alfred Wegener |
The theory that the today's continents were once part of a single landmass. | Theory of Continental Drift |
Theory that developed from the Continental Drift Theory that the Earth's surface is made up of giant moving slabs. | Theory of Plate Tectonics |
The process where new sea floor is formed. | seafloor spreading |
