two plates slide past each other, causing the crust of each plate to start falling apart. Soon, a crack forms between the two plates. Which type of boundary is the statement describing?

a convergent boundary
b transform boundary
c divergent boundary
d trench boundary

b transform boundary

The statement describes a scenario where two plates are sliding past each other, which is characteristic of a transform plate boundary. This type of boundary does not typically involve the crust falling apart but rather grinding alongside each other, which can cause earthquakes. However, the description of a "crack" forming between the two plates might be interpreted as the development of a fault, which is a common feature at a transform boundary.
