B.mantle convection
C.subduction
D.trench formation
The correct option is (B)mantle convection
Tectonic plates at the earth's surface move because of the intense heat in the Earth's core. this heat causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell and producing a movement called mantle convection which is the slow creeping motion of Earth's solid silicate.

Answer:
Here's the answer.
the minimum amount of horizontal force that the man will need to apply so
that the tree will start moving?
A. 240 N
B. 360 N
C. 480 N
D. 120 N
Answer:
120 N
Explanation: First we shoud consider the forces acted on a tree
Friction foce - acting opposite to the moving direction
Weight - Directly acting downwards
Reaction - Directly acting on upwards
For minimum required force should be equal to the friction force
F = μ R
F = 0.5×480
= 120N
Well, the force that originally caused it to start moving was inertia, but the forces that cause it to stop are friction and gravity. Gravity pulls the object towards the center of the Earth, causing it to slow and eventually stop, and friction is the resistance between the ball and the ground (or whatever).
Hope this helps!
