Correct Answer
A. A narrow. fast moving riverExplanation

The term "narrow" indicates that the river is not wide but has a restricted width. The term "fast-moving" suggests that the water in the river is flowing swiftly, indicating a strong current. Therefore, the correct answer is "A narrow, fast-moving river."Rate this question:

What happens when surface currents get near land?
-
The land explodes
-
The currents change direction
-
The currents swallow up the land
Correct Answer
A. The currents change directionExplanation
When surface currents get near land, they experience a change in direction. This is because the presence of landmasses disrupts the flow of the currents, causing them to alter their course. This change in direction can be influenced by various factors such as the shape of the coastline, the depth of the water, and the interaction between the current and the land. The currents may deflect, split, or even form eddies as they encounter the land, resulting in a shift in their overall direction.Rate this question:
