Am i right? i picked
how is earth's surface most likely to change when a river flows across a steep landscape over time?
it will form into a mountain due to deposition
physical weathering will create a channel with curvy loops
a valley will be carved out due to erosion
alake will form due to chemical weathering

C

Explanation:

Your correct because over time the water will cause erosion. Good luck with the rest of your hw

Option (3)

Explanation:

Generally, when a river flows, it erodes the materials away, by down-cutting as well as on the edges.

In a steep slope, when a river flows, the water continuous flows and erosion takes place extensively. It is because the rocks and the soil materials are significantly eroded, resulting in the down-cutting. This eventually leads to the formation of a narrow valley along the slope of the mountain.

Thus, due to the flow of a river across a steeper landscape, a valley is most likely to form due to continuous erosion.

Thus, the correct answer is option (3).

poor water quality affects most estuarine organisms, including commercially important fish and shellfish. the pollutants that have the greatest impact on the health of estuaries include toxic substances like chemicals and heavy metals, nutrient pollution (or eutrophication), and pathogens such as bacteria or viruses.
