Earth's Interior

What are two types of evidence to support what the interior of Earth is like?

• Rocks and seismic waves

• Plate tectonics and continents

• Drilling and mining

• There is no evidence

How do rocks from deep in the interior reach the surface?

• Seismic waves

• Tsunamis

• Volcanic eruptions

• Drilling holes

What are the three main layers of the Earth?

• Lithosphere, asthenosphere, core

• Crust, mantle, core

• Inner core, outer core, mantle

• Crust, outer core, inner core

What is continental crust made up of?

• Basalt

• Rhyolite

• Granite

• Andesite

Where does the heat from Earth’s interior come from?

• Leftover heat from Earth's formation & radioactive decay

• Leftover energy from the Big Bang

• Solar energy from the Sun

• The spinning of the outer core

Why does pressure increase the deeper you go into the Earth?

• Because the crust is solid

• Because the mass of the rocks stays the same

• Because the mantle is plastic

• Because of the weight of the rocks above

What is ocean crust made up of?

• Gabbro

• Basalt

• Sandstone

• Granite

What is the lithosphere made up of?

• The upper mantle and the lower mantle

• The lower mantle and the outer core

• The crust and the upper mantle

• The crust, the mantle and the core

What is the composition of the asthenosphere like?

• It is completely melted, molten rock

• It is completely solid rock

• It is partially molten, plastic-like

• It is similar to ocean water

What is responsible for the creation of Earth’s magnetic field?

• The radioactive decay of elements

• The energy from the Sun

• The spinning of the liquid outer core

• The leftover heat from Earth's formation
