1. 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

2. 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

3. 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
