there has been multiple ice ages on earth. what causes ice ages?

Answers

Answer 1
The onset of an ice age is related to the Milankovitch cycles - where regular changes in the Earth's tilt and orbit combine to affect which areas on Earth get more or less solar radiation. When all these factors align so the northern hemisphere gets less solar radiation in summer, an ice age can be started.
Answer 2

Answer:

The variation of sunlight reaching Earth is one cause of ice ages. .

Explanation:

When less sunlight reaches the northern latitudes, temperatures drop and more water freezes into ice, starting an ice age.

When more sunlight reaches the northern latitudes, temperatures rise, ice sheets melt, and the ice age ends.

is it bad for land to be grazed until the soil is bare ?​

Answers

Answer:

Absolutely yes

Explanation:

according to a report of Food and Agriculture Organization of the United Nations, an area is called Sarigua which is located in the West of Panama, has become desert after excessive grazing of livestock and losing topsoil due to erosion

Answer:

Without the plants or vegetation cover, the soil is left bare and exposed to harsh weather such as heavy downpour and high temperatures, which disintegrates the rocks and carries the topsoil away. Animals also prefer gathering at specific areas, like next to water sources, and such areas can get eroded.
