Explain how an igneous rock like granite changes into a sandstone?
Leokris [45]

Answer:

Granite changes into sandstone by means of weathering and erosion. Through the passage of time, fragments of granite are broken down into smaller pieces, or sediments, which are transported and deposited at the bottom of the oceans or rivers. These particles form layers of sand and pebbles that undergo compaction and cementation to create sandstone.

Arlecino [84]

<u>Answer:</u>

Subsistence agriculture is when the activity of growing food is not associated with economic gains and is only carried out in order to feed the cultivator himself and his family.

<u>Explanation:</u>

The word subsistence literally means support. The farming that is done by the farmers to support their survival is thus known as subsistence farming. In subsistence farming, the farmers choose to grow food that would only be enough to fulfill their own needs of survival.

There are no economic gains possible from subsistence agriculture as there is no surplus produce that can be traded to fetch economic gains.
