When tectonic plates slowly push against each other, forces build up and eventually the plates move to release the tension. The movement of the plates is
caused by- *

The movement is caused by the convection currents that roll over in the upper zone of the mantle. This movement in the mantle causes the plates to move slowly across the surface of the Earth.

Explanation:

i think its c. amphipod

acceleration= v2-v1/t so 8m/s-3m/s / 3s =to 8/3 or

2.67 m/s^2

hope i
