Seafloor spreading is found at which type of plate boundary?

Answer 1

.At spreading boundaries, plates move away from each

other and gaps form between the plates. Convection

currents cause magma to rise from the mantle through

these gaps. Huge valleys can form. This type of plate

movement is responsible for seafloor spreading. The

Mid-Atlantic Ridge formed at plate boundaries that

were moving apart.At fracture boundaries, plates slide past each other.

This break in Earth's crust is called a fault. The

movement of the plates past each other can cause

strong earthquakes.The area where two plates push against each other is

called a colliding boundary. When plates collide, one

plate might slide beneath the other. When plates carry

continents into each other, towering mountains form.

Other times, deep ocean trenches, earthquakes, and

volcanoes can result.
