How can two lithospheric plates move relative to each other?
They can only converge or diverge.
They can only collide or slide along each other.
They can collide, pull apart, or slide against each other.

Earth's geography is continually changing.
all geological activity happens at plate boundaries.
continents drift but scientists do not yet know why.
At transform plate boundaries, two plates move toward each other.
True
