### What defines the power of a River?

• A.

Its current

• B.

It's length

• C.

It's width

• D.

The people who depend on it

A. Its current
Explanation
The power of a river is defined by its current. The speed and force of the water flowing in a river determine its ability to erode, transport sediment, and generate energy. A river with a strong current will have more power to shape the landscape, carry larger particles, and potentially generate more hydroelectric power. The length and width of a river may influence its overall volume and discharge, but it is the current that ultimately determines its power. The people who depend on the river may be affected by its power, but they do not define it.

B. The snow on top of the mountain

Therefore, the snow on top of the mountain is a clear indication that it is really cold there.
