Question

How does a pond form?

1. A mud flow blocks a river.
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 1

2. Water collects in a low-lying area

Step-by-step 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.
