Label the following diagram:

	1) Select here: Mantle Crust Inner core Outer core	State? Solid Dense liquid
	2) Select here: Mantle Crust Inner core Outer core	State? Solid Dense liquid
	3) Select here: Mantle Crust Inner core Outer core	State? Solid Dense liquid

4)  What is the outer shell of the Earth called? Select here: Mantle Crust Inner core Outer core

5)  The Earth is sphere with a diameter of about ? 25,000 12,700 40,000 6,300 Kilometres. As we go deeper and deeper into the earth the temperature and pressure ? falls increases remains the same . The core temperature is believed to be an incredible 5000-6000°C. The overall density of the Earth is much higher than the density of the rocks we find in the ? Mantle Crust Inner core Outer core . This tells us that the inside must be made of something much   ? Lighter Denser Viscous Magnetic than rock. Scientists can follow the path of ? magnetic seismic mexican waves from earthquakes as they travel through the Earth, the s waves from an earthquake do not travel through ? solids liquids rocks iron which causes a shadow zone.

The crust is a very thin layer. The thinnest areas are under the ? continents mountains oceans and go to a depth of roughly 10 kilometres. The thickest areas are under the ? continents oceans which extend down to 35 kilometres on average. The crust in the Himalayas is some 75 kilometres deep.

The mantle is made of solid rock but behaves like an extremely viscous liquid when viewed over immense timescales. The ? Earth's magnetism convection of heat Earth's rotation from the centre of the Earth is what ultimately drives the movement of the tectonic plates and cause ? mountains to rise erosion to occur valleys to form . The source of this heat is ? magnetism fields volcanoes the Earth's rotation radioactive decay occurring deep within the Earth.
