Chapter 13, Problem 1GST

To determine

The match for each of the processes of a, b and c with the given zones depending upon the dominant processes operating in the different parts of a river system.

Answer to Problem 1GST

The dominant processes that match with the zones are as follows:

Zone #1: a. sediment production.

Zone #2: c. sediment transportation.

Zone #3: b. sediment deposition.

Explanation of Solution

Streams are channels of water that flow on the surface of the earth. Streams flow in different networks and finally join the surface water in the sea.

Zone #1: a. sediment production. This is a zone in which most of the sediments are originated or developed mainly due to erosion and by mass wasting, and overland flow. This zone is mainly located in the headwater region of a river system.

Zone #2: c. sediment transportation. Here, the sediments from the production zone are transported through the drainage network in a balanced state of erosion and accumulated along the banks of stream channels.

Zone #3: b. sediment deposition. This is a zone in which the river reaches the ocean or a large body of water such as lake. The energy of transported sediments will reduce and accumulated as deltas and different coastal features and the further movement of sediments led to deposition on the ocean basins.
