C2

Front 1

Crust

Back 1

thelast layer on top of the Earth. It is relatively rocky and thin

Front 2

Mantle

Back 2

is below thecrust and is above the core (the zone between the core and the crust). Has theproperties of a solid but can flow. The Earth’s core transfers energy, so thetemperature of the mantle increases with depth.

Front 3

Core

Back 3

Outer core- is theliquid layer made of iron and nickel

Inner core- isthe solid layer made of iron and nickel.

Front 4

Lithosphere

Back 4

ismade of the crust and the outer mantle. It is the outer layer of the Earth andis relatively cold and rigid. The lithosphere is made of tectonic plates which areless dense than the mantle below

Front 5

Asthenosphere

Back 5

is thehot, semi-rigid layer below the lithosphere that flows slowly and causes thetectonic plates to move

Front 6

Subduction

Back 6

when the oceanic and continental plates collide, the oceanic plate sinks below and partially melts.

Front 7

Magma

Back 7

molten rock beneath the Earth's surface

Front 8

Lava

Back 8

molten rock above the Earth's surface

Front 9

Igneous rock

Back 9

when molten rock cools down and solidifies

Front 10

Basalt

Back 10

an igneous rock rich in iron and is from fairly safe eruptions

Front 11

Rhyolite

Back 11

an igneous rock rich in silica and is from violent eruptions

Front 12

Extrusion rocks

Back 12

cool down very quickly and as a result have small crystals

Front 13

Intrusion rocks

Back 13

cool down very slowly so would have very large crystals

Front 14

Marble is

Back 14

a metamorphic rock

Front 15

Granite is

Back 15

a hard igneous rock

Front 16

Limestone is

Back 16

a soft sedimentary rock
