Answer:
D. Thermal expansion
Explanation:
MECHANICAL WEATHERING
can be defined as the gradual disintegration of rock into smaller particles which later turn into soil. when mechanical weathering occurs, it doesn't change the chemical composition of the rock. mechanical weathering are caused by abrasion by ice water, thermal expansion, root of trees growing on the rock.
THERMAL EXPANSION
This is a mechanical process of weathering. during the day when there is high temperature and hits the rock surface, the rock absorbs heat expands . at night when the temperature drops the rock contrast. Repeated action of expansion and contraction results in gradual breakdown of rock to form soil.
The answer is A.
Hope this helps :)
Answer:
Let me count a few of the ways…
- Plants do not take life of any kind to sustain their own lives.
- Plants harvest atmospheric carbon dioxide (a waste product), water and sunlight (both ubiquitous and freely available) to produce within themselves the food which nourishes them.
- Plants are born and die in the same place.
- Plants have yet to start a war, perpetrate a genocide, or kill members of their own species over disagreements about mere ideas.
- When plants die, they do not entertain silly notions of a Better Place, somewhere beyond the stars.
