Questions: Where two plates move by each other laterally in opposite directions, it is called a hot spot. a convergent boudary. a transform boundary. a divergent boundary.

The answer is the third one: a transform boundary.

Explanation for each option:

1. A hot spot: This is incorrect. A hot spot is a location on the Earth's surface that has experienced active volcanism for a long period of time, typically due to a mantle plume. It is not related to the lateral movement of tectonic plates.
2. A convergent boundary: This is incorrect. A convergent boundary is where two tectonic plates move towards each other, often resulting in one plate being forced below the other, leading to mountain building or subduction zones.
3. A transform boundary: This is correct. A transform boundary is where two tectonic plates slide past each other horizontally. This lateral movement can cause earthquakes along faults, such as the San Andreas Fault in California.
4. A divergent boundary: This is incorrect. A divergent boundary is where two tectonic plates move away from each other, typically resulting in the formation of new crust as magma rises to the surface, such as at mid-ocean ridges.

Summary: The correct term for the situation where two plates move by each other laterally in opposite directions is a transform boundary.
