Front

What is the most important factor affecting a planet's average temperature?

Back

The distance from the sun is the most important factor affecting a planet's average temperature.

Front

What are the three types of tectonic plate boundaries?

Back

Convergent, divergent, and transform boundaries.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, often resulting in the formation of new crust.

Front

What is the role of the atmosphere in determining a planet's temperature?

Back

The composition of the atmosphere can trap heat and influence a planet's temperature.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates collide, often causing one plate to be forced beneath the other.
