Question

A man digging a pit found that he could dig with ease intially but digging became diffcult as he went deeper . he could not dig beyond a depth of 5 feet . Provide a suitable scientific explanation .

Answer 1

It is easier to dig soil initially because the upper layer of the soil consists of topsoil and subsoil. These two horizons are composed of loose soil particles and easy to dig. At the deeper layers, partially weathered rocks or bedrocks are present. It is very difficult to dig through partially weathered rocks or bedrocks.

Answer 2

A man digging a pit found that he could dig with ease intially but digging became diffcult as he went deeper . he could not dig beyond a depth of 5 feet . Provide a suitable scientific explanation .

When the man started to dig the pit he was having more energy so he was able to dig the pit with ease. But as he continued to dig the pit he gradually started losing his energy. As he reached a depth of 5 feet his energy completely exhausted so he could not go any further deep.

This is the reason why he was unable to dig beyond 5 feet.

Hope it helps :-)
