Geologic Time and Fossils

Most of the rocks on Earth's surface are formed this way

• Molten magma cooling off on Earth's surface

• Asteroids striking the Earth's surface

• Sediments forming layers on Earth's surface

• Ocean waves pushing rocks on Earth's surface

• 100 years

• 1,000 years

• 1,000,000 years

• Nobody knows for sure
