Earth’s Layers

1.crust – the thin and solid outermost layer of Earth above the mantle

2.mantle – the layer of rock between the Earth’s crust and core

3.core – the central part of the Earth below the mantle (outer core/inner core)

4.lithosphere – the solid, outer layer of the Earth that consists of the crust and the rigid upper part of the mantle

5.asthenosphere – the soft layer of the mantle on which the tectonic plates move

6.mesosphere – the strong, lower part of the mantle between the asthenosphere and the outer core

7.tectonic plate – a block of lithosphere that consists of the crust and the rigid, outermost part of the mantle

8.oceanic crust – part of the crust made up of basalt (rock)

9.continental crust – part of the crust made up of granite (rock)

10. magma -molten rock under Earth’s surface

11. lava – molten rock above Earth’s surface

12. geology – the study of Earth’s surface (rocks)

13. convection currents - the movement of a fluid, caused by differences in temperature, that transfers heat from one part of the fluid to another
