Core

The Earth

10km to 100km thick

Extends almost halfway to centreSolid properties but flows

Iron & NickelJust over half the Earth’s radiusLiquid outer coreSolid inner core

The average density of the Earth is much greater than the density of the rocks that form the crust. This means that the interior of the Earth is made from different and denser materials than the crust


The earth rocks

Sedimentary rocks

Metamorphic rocks

Igneous rocks

The Rock Cycle

LayersRipplesFossils

Formed by high pressure & temperatureEvidence of mountain building processesAssociated with Earth movements

Have been moltenCrystalsIntrusive – big crystalsExtrusive – small crystals


The earth rocks

Tilted

Fractured

Folded

Upside down

The Crust

Young

Sedimentary rocks in layersYounger rocks usually on top of older rocks

Old

Sedimentary rocks are also found:

This shows that the Earth’s crust is unstable and has been subjected to very large forces
