A. The difference between a river and a lake:

1. A river is a large, flowing body of water that usually empties into a sea or ocean. It is a dynamic system, constantly moving from its source to its mouth. Rivers can be found all over the world and they vary in size, length, and water volume.

2. A lake, on the other hand, is a large body of water surrounded by land. Unlike rivers, lakes are static, or standing bodies of water. They can be formed through various geological processes like tectonic activity, glacial activity, and volcanic activity.

B. The difference between the mouth and source of a river:

1. The source of a river is the original point from where the river flows. It could be a spring on a hillside, a melting glacier, or a lake. The source is usually found in high places such as mountains or hills.

2. The mouth of a river is the place where the river flows into a larger body of water, such as another river, a lake, a sea, or an ocean. The mouth of a river is usually found at lower elevations.
