Question

examine environmental changes that affected the health of a lake
lake mojave is an ancient lake that has dried up and no longer exists in the mojave desert in california.
which environmental conditions may have occurred to cause the disappearance of the lake and the organisms that live in it? check all that apply.
□ decrease in rainfall in the mojave desert
□ decrease in temperature in the mojave desert
□ decrease in runoff that flows into mojave lake
□ increase in blocked streams that flow into mojave lake
□ increase in pollution that was deposited into mojave lake
□ increase in the nonnative plant population in mojave lake

Explanation:

• A decrease in rainfall reduces the lake's water input, leading to drying.
• Less runoff cuts the lake's freshwater supply, causing it to shrink.
• Blocked streams stop water from reaching the lake, reducing its volume.
• Increased pollution can poison aquatic life and disrupt the lake's ecosystem, contributing to its collapse.
• A temperature decrease would reduce evaporation, which would not cause the lake to dry up.
• An increase in nonnative plants alone would not directly dry up the entire ancient lake.

Answer:

• decrease in rainfall in the Mojave desert
• decrease in runoff that flows into Mojave lake
• increase in blocked streams that flow into Mojave lake
• increase in pollution that was deposited into Mojave lake
