A. If the sediments in the stream bank were lithified, what kind of sedimentary rock would they form?

b. How would you describe the change or evolution of sediments between the tributary streams and the main Merced River?

(a) Clastic sedimentary rock.

(b). Gradualism.

Explanation:

A

They can be refered as Clastic sedimentary rocks, they also exist as

breccia, conglomerate, sandstone,

siltstone, and shale are formed from mechanical weathering debris.

(b). Similar to other Sierra Nevada tributaries, the Merced River transitions from steeper, gravel bedded

reaches affected by gold dredging and aggregate mining, to areas where various activities have

encroached on the stream channel, and then to a lower gradient sand bedded reach.

The sediments are transfered gradually from the stream directly to the main river.
