What two ways do geologists use to study the Earth's core?

• Volcanoes

• Earthquakes

• Rock Samples

• Core Samples

Where are convection currents found inside the Earth?

• Crust

• Lithosphere

• Asthenosphere

• Upper Core

Convection currents are caused by differences in what TWO things?

• Rock type

• Temperature

• Density

• Pressure

What is happening at Point A?

• Material is heated again by the core, lowering the density

• Less dense material is heated and begins to rise

• Rising material hits lithosphere and slides, moving plates with it

• Material cools, becoming denser, then begins to fall due to gravity
