Earth Science

Why do plates move? 

• Convection currents in the mantle cause plates to move.
• The outer core spins
• The inner core is magnetic
• The plates are floating on an ocean

The idea that the continents are slowly moving over Earth's surface

• law of superposition

• evolution

• continental drift

• absolute age

A plate moving along a fault often causes...

• an earthquake.

Which statement is true?

• The oldest layers of rock and soil are closest to the surface of the earth
• The youngest layers of rock and soil are farther away from the surface of the earth.
• Carbon-14 dating is an example of relative dating, and the law of superposition is an example of absolute dating.
• Absolute geologic dating and relative geologic dating are two methods used by scientists to determine the age of geologic evidence.

What role do faults play in the Law of Superposition?

• Faults create new types of rock.
• Faults are younger than the layers they cut through.
• Faults are the same age as the layers they cut through.
