Tributes

38
Q

Land area that gathers water for major rivers is called a

A

drainage basin

39
Q

A boundary that separates distict drainage basins is called

A

drainage divide

40
Q

As water flows downhill under the influence of gravity, water erodes earths surface creating.

A

channels

41
Q

Young rivers are V shaped due to the fast movement.

A

V shaped

42
Q

Mature rivers are wide with smooth and gentle slopes.

A

Mature

43
Q

Flood plains

A

When rivers flood and drop their sediment load, it is called flood plains.

44
Q

Deltas

A

A fan shaped sediment deposit will form at the mouth of a river into another body of water.
dis tributaries are the branching channels.

45
Q
