When plate tectonics cause cracks to form, _____________.

scientists expect entire continents to fall into the Earth
volcanoes can occur
a large rift usually remains and is never filled in
most likely the country of Mexico will separate from the continental United States

Respuesta :

I think it's the 2nd one,  Volcanoes can occur.

Answer:

The answer is B.

During plate tectonics, cracks may occur in the earth crust that causes magma to rise up from the mantle. The cracks may also cause cracks to form on the crust that makes outlet channels for the magma in magma chambers. These result in volcanic eruptions on the surface of the earth that form volcanic features such as mountains.
