Question

how is the process of new crust formation at divergent boundaries balanced on earth? by the disappearance of crust at other locations by the uplift of mountain ranges by the constant influx of meteorites

Explanation:

Earth's total crust volume remains relatively stable. At divergent boundaries, new crust forms as tectonic plates pull apart and magma rises to solidify. This is balanced by the destruction (subduction) of old crust at convergent boundaries, where one plate is pushed under another and melts back into the mantle. Mountain uplift and meteorite influx do not balance new crust formation.

Answer:

by the disappearance of crust at other locations
