Convection in the mantle and pressure of magma on the edge of the plate
Explanation:
Convection currents occur in the mantle because the upper mantle (asthenosphere) is generally cooler than the lower mantle. The convections apply upward pressure on the lower edges on the lithosphere as the melted rocks upwell from below. The lithosphere deflects the convections and as the convections churn clockwise of anticlockwise, they drag the lithosphere with it via friction. This is what is stipulated to cause tectonic plate movements.

The <em>Acadians</em> ... who came from the French-speaking <em>Acadiana</em> region in
Canada, navigated all the way down the east coast of the US, around Florida,
and then for some mysterious and eternally inexplicable reason decided to settle
on the Gulf Coast of Louisiana, generally between Nawlins and Lak Charlie ...
soon became addressed by the locals there as " <em>Cajuns</em> ".
Natural cracks in the rock that form due to the exhumation of deeply buried rock are called salt wedges.
Answer: Option 1
<u>Explanation:
</u>
The process of exhumation in the discipline of Geography refers to digging up of a buried rock due to natural forces applied on the surface under which the rock is buried. At a salt wedge, a river flowing with a great velocity meets the ocean where the ocean is comparatively calm.
The fast-flowing river water acts as a digging force and carries out the process of exhumation of the rocks at the wedge. The same fast-flowing water creates cracks in the exhumed rocks.
The answer to this would be A, because they began to spread westward once they decided to head away from the Arctic.
