How is soil erosion

Posted by Pari Patel 7 years ago

CBSE > Class 07 > Science

1 answers

Yogita Ingle 7 years ago

Denudation of the soil cover and subsequent washing down is known as soil erosion.
Causes of soil erosion:

Due to human activities like deforestation, overgrazing, construction and mining, etc.
Natural forces like wind, glacier and water leads to soil erosion.
The running water cuts through clayey soils and makes deep channels as ‘gullies’. The land becomes unfit for cultivation, this process is called gully erosion and the land is called bad land or ravines in the Chambal basin.
Sometimes, water flows as a sheet over large areas down a slope. It leads to the washing away of the top soil. This process is called sheet erosion.
Wind blows loose soil off flat or sloping land, and is called wind erosion.
Soil erosion is also caused due to defective methods of farming

When pollen from a plant's stamen is transferred to a different plant's stigma, it is called cross-pollination. ... The plants must be of the same species. For example, only pollen from a daisy can pollinate another daisy. Pollen from a rose or an apple tree would not work. For fertilization to occur in angiosperms, pollen has to be transferred to the stigma of a flower: a process known as pollination. Gymnosperm pollination involves the transfer of pollen from a male cone to a female cone. ... After fertilization, the zygote divides to form the embryo and the fertilized ovule forms the seed.
