Question

eurasian and north american plates are separating, causing distinct geological features such as rift valleys. this makes it a prime location for studying plate tectonics. this process of new crust formation at divergent boundaries is balanced by crust disappearance elsewhere on earth. how is the process of new crust formation at divergent boundaries balanced on earth? by the disappearance of crust at other locations by the constant influx of meteorites by the uplift of mountain ranges

Explanation:

The text states "This process of new crust formation at divergent boundaries is balanced by crust disappearance elsewhere on Earth." So we check the options: the first option matches this statement, the second (meteorites) is not related to crust balance, and the third (mountain uplift) doesn't balance new crust formation.

Answer:

A. by the disappearance of crust at other locations
