Question

Why are annual temperature ranges in the southern hemisphere generally smaller than those in the northern hemisphere?

Answer 1

Answer:

Northern hemisphere has less water body than Southern.

Explanation:

Variation in land and sea distribution is seen in different hemispheres of the Earth.

In Northern hemisphere, land occupies more area than water when compared with Southern hemisphere.

Northern hemisphere has approximately 40% land and 60% water body.

Southern hemisphere has approximately 20% land and 80% water body.

Land absorbs more heat and thus northern hemisphere has more annual temperature than southern.

Answer 2

Answer:

There is less land and more water in the southern hemisphere.

Water tends to heat up and cool down slowly as compared to land.

There is also less pollution in the southern hemisphere, probably becuase of low population density there.

That is why annual temperature ranges in the southern hemisphere are generally smaller than those in the northern hemisphere because climate in the southern hemisphere is milder than that of the northern hemisphere.
