What is the difference between adaptation and variation?

Back

Adaptation is the process by which a species becomes better suited to its environment, while variation refers to the differences among individuals within a species.

What is a convergent boundary?

Back

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