What is the best approximation of the average atmospheric temperature fluctuation between ice ages and interglacial periods?

The average temperature during the glacial period or ice age is approximately 5 degrees colder than Earth's current temperature or inter-glacial period.

EXPLANATION:

A glacial period gives the period of ice age whose temperature is specified by colder temperatures and glacier advances. Inter-glacial period shows the warm temperature between glacial periods. Earth currently exhibits in this inter-glacial period.

The change in temperature is based upon the amount of heat radiation received by Earth in Northern hemisphere. The inter-glacial period happens when solar radiation is more intense. It has been observed that the glacial periods end abruptly, maybe due to the atmospheric Carbon-dioxide.

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.

b.have there own function.
