Before Earth cooled, volcanoes were

• active on Earth's surface

• inactive on Earth's surface

• did not exist on Earth's surface

• being created on Earth's surface

Earth, and the rest of the solar system, formed from a giant cloud of gas and dust in space called a __.

• protosun

• nebula

• galaxy

• comet

Where does Earth's internal heat come from?

• The Sun

• The pressure in the Earth

• Gravity

• Heat of Formation and Radioactive decay

Earth's Inner core is?

• A layer of rock that forms Earth's outer surface

• A layer of molten (liquid) iron and nickle

• A layer of solid iron and nickel

• A solid/plastic layer of Peridotite that flows over time?
