) view.. In contrast to this main stream, the tributaries tend to flow parallel to one another in weaker layers of rock. This general pattern is best described as ________.
The Ugab river and its tributaries show a Trellis Drainage Pattern.
Explanation:
The name tellis comes form the Trellis structure in a garden. This is because in this drainage pattern, the tributaries enter the main river at an angle of approximately 90 degrees.
This pattern occurs when the main river cuts across hard rock, while the tributaries flow accross layers of soft rock, as it happens northwestern Namibia, where the Ugab river is located.

Mechanical weathering involves the breakdown of the rocks into small pieces by the external support such as pressure whereas Chemical weathering involves the breakdown of the rocks takes place by the chemical process.
Mechanical weathering is a physical change that is caused by the movement of wind and water whereas chemical weathering takes place when the chemicals present in the air or water get mixed with minerals or rocks.
