1. Which of the following types of stream channels tends to only form in areas where underlying geology is highly resistant to weathering and erosion.
Answer: Straight
Explanation: Straight channel are typically found in the areas of highland or mountainous region. They are also found in an underlying weak rock layer in an area. In straight channel the velocity of the water is fast. Its discharge is also high. The channel is often deeper than it is wide, and most erosion occurs along the stream bed.
2. which of the following term is used to define measurement of the largest size particle that a stream can transport
Answer: c. competence
Explanation: Stream competency is a measure of the maximum size of particles a stream can transport.
3. What depositional landforms on the inside of the meandering sream curve.
Answer: b.Point bar
Explanation: Point bars are deposited on the inside of a meander sream curve.
