Answer:
The force of gravity can cause erosion by;
- pulling rocks and other particles down the side of a mountain or cliff
- it can cause landslides which significantly erode an area.
Two main factors :
First, the distance from the earth to the sun allows enough heat (energy), not too much, to be absorbed on earth's surface.
Second, earth's atmosphere allows it to keep most of the heat it absorbed during the day for the night. Otherwise, temperatures would drop down below a life sustaining point.
Answer:
Uses of genetic engineering include:
increasing plant food production
improving medical treatment
Explanation:
Genetic engineering can be described as a technique in which the genome of an organism is manipulated for the benefit of humankind. The processes of genetic engineering involved the manipulation of the plants and animals DNA so that they will be able to produce more better characteristics. Also, drugs such as vaccines can be produced in animals by the techniques of genetic engineering.
