Which feature helps to identify a landscape that been developed mostly by stream action?

1 marine terraces well above sea level
2 sand dunes and other coastal deposits
3 "V" shaped valleys and little soil
4 parallel hills and unsorted sediments.

isnt the answer 1

I think the correct answer is 3

marine terraces are formed by the erosion of rock by wave action. (waves hitting the exposed rock)

sand dunes aer formed by wind erosion.

parallel hills, I'm not sure about but apparently they can be foremed by melting glacial ice (and thus they can have unsorted sediment)

V shaped valleys would be my guess, since if you imagine a stream cutting into a rock formation (example: grand canyon) it would form this shape.

Yes, 3. is the answer. 1 is caused by coastal wave action and uplifting.

Actually, the correct answer is 3 "V" shaped valleys and little soil. This feature is characteristic of a landscape that has been primarily shaped by stream action.

To understand why this is the correct answer, let's break down each option and evaluate its relevance:

1. Marine terraces well above sea level: Marine terraces are flat or gently sloping platforms that were once at sea level but have been uplifted above it. While stream action can contribute to the creation of marine terraces, they are not a direct indication of a landscape developed mostly by stream action.

2. Sand dunes and other coastal deposits: Coastal deposits such as sand dunes indicate the influence of wind and coastal processes, not necessarily stream action. Therefore, this feature is not a strong indicator of a landscape developed mostly by stream action.

3. "V" shaped valleys and little soil: This feature is closely associated with stream erosion. As streams erode the land over time, they tend to create "V" shaped valleys, especially in areas with little vegetation and minimal soil development. Hence, "V" shaped valleys and little soil are key indicators of a landscape shaped by stream action.

4. Parallel hills and unsorted sediments: Parallel hills and unsorted sediments are more characteristic of glacial or fluvial deposition, not necessarily stream action. Therefore, this feature is not strongly associated with a landscape developed mostly by stream action.

In conclusion, the best answer is 3 "V" shaped valleys and little soil, as it aligns with the characteristics expected to be present in a landscape shaped primarily by stream action.
