Please answer correctly. I really need this. Its not a joke. Thank you
1. What conditions might cause the most water and sediment to be collected at the bottom of the stream table?

Steep, high velocity, no silting. The high water speed picks up silt from the bottom instead of letting it settle to the bottom. When the land gets level like often happens at the mouth of rivers where the water spreads out and slows down, silt settles to the bottom and you could get a wide, shallow delta.

(Put in own words this is from online hope it helps)

stress fractures occur largely in the feet and legs and are common in sports that require repetitive impact, primarily running/jumping sports such as gymnastics or track and field.
