Question 15 of 35
Solnce55 [7]

The statements that describe how the pond turned into the bog is as follows: Large water plants grew in shallow water around the edge of the pond.

<h3>What is a pond?</h3>

Pond is an inland body of standing water, either natural or man-made, that is smaller than a lake.

A bog is an area of decayed vegetation (particularly sphagnum moss) which forms a wet spongy ground too soft for walking.

This means that a pond can become a bog when existing plants in the pond decays until the land becomes soft.

Therefore, the statements that describe how the pond turned into the bog is as follows: Large water plants grew in shallow water around the edge of the pond.
