Answer 2

The correct answers are:

- Decrease in rainfall in the Mojave desert;

The decrease in rainfall can be devastating to a lake's waters and biodiversity. The decrease in rain usually causes bigger loss of water through evaporation than water coming in the lake, so over time it will dry out, or just small pieces of it will remain.

- Decrease in runoff that flows into Mojave Lake;

If the amount of water that comes into the lake decreases, it can be fatal to it, and in a very short period of time, since the lake will be losing more water than it gets in.

- Increase in blocked streams that flow into Mojave Lake;

Naturally, streams can be blocked and redirected, so if this happens, we have the same situation from before, where the water income is smaller than the water loss of the lake.
