Question

question: what flushes a freshwater lake? answer options: select one of four rainwater groundwater river oceanwater

Explanation:

To determine what flushes a freshwater lake, we analyze each option:

• Rainwater: While it contributes to lake water, it doesn’t “flush” (replace or circulate) the lake’s water in the primary sense.
• Groundwater: Usually interacts with lakes through seepage, not flushing.
• River: Rivers can flow into and out of lakes, transporting water (and nutrients/sediments) to “flush” the lake by replacing or circulating its water.
• Oceanwater: Freshwater lakes are distinct from oceans, so ocean water does not flush them.

Answer:

River
