What can cause rapid shifts in the Earth's climate?

Back

Meteor impact, variations in solar output, and volcanic eruptions can cause rapid shifts in the Earth's climate, but slow changes in ocean currents cannot.

What are the types of plate boundaries?

Back

The three main types of plate boundaries are divergent, convergent, and transform boundaries.

What is a transform boundary?

Back

A tectonic plate boundary where two plates slide past each other horizontally.
