Give some uses of lakes for human.
A lake helps to regulate the flow of a river.
They do not moderate the climate of the surroundings.
During heavy rains, it maintains the even flow of water.
Helps to develop tourism and provide recreation.
The process of excessive nutrient input and subsequent plant and algae growth is called ___________________________.
decomposition
eutrophication
photosynthesis
succession
How exactly do glaciers form lakes?
Only the melting of glaciers causes the bowl shape area.
The glaciers formed during the ice age in calderas that were already shaped by geological activity.
The movement of those large glacial deposits eroded the land over time.
None of these are correct.
Volcanic lakes are formed by the water filling of the craters of extinct volcanoes and have more of a circular shape.
False
True
marshes, swamps, and moorlands
A marsh and a swamp are the same thing.
True
False
Marshes are formed by sediment
erosion
deposition
