2. Water collects in a low-lying area.
3. Humans use a dam to create a reservoir.
4. A depression made by an ice sheet fills with water.

Answer:

Water collects in a low-lying area.

Explanation:

Answer:

2. Water collects in a low-lying area

Explanation:

It forms like this:

  • Ponds are not formed due to blockage due to mudflow in a river nor due to dam constructions.
  • The depression due to ice sheets is not filled with water and does not create ponds or freshwater sources.
  • When water gets filled in low-lying areas and large pits with water from rainfall or any other sources are called a pond.

So number 2. Water collects in a low-lying area is right.

Hope it helped. :)
