Answer:
1)State some economic benefits of rivers and lakes.
Rivers refer to any natural stream of water that flows in a channel with defined banks. Lakes refer to any large body of water surrounded by land. The basis of understanding rivers and lakes is the hydrological cycle. The hydrological cycle refers to the movement of water from the atmosphere to Earth’s surface and thence to the oceans. Rivers and lakes are the permanent freshwater inland surface waters, including watercourses and water bodies.
The difference between River and Lake is the movement of its water.
A river runs along its banks and flows in one direction.
On the other hand, a lake is immobile. Therefore, it is regarded as a still water body.
