Answer:
The principal difference is the amount of organic content in the soil
Explanation:
In warm places of the world there is a lot of life, there we can find big forests where are living thousands of animals and plants; when this organisms die they rest on the ground and start a descomposition until become part of the soil. This kind of soil is very dark, almost black, is humid and very rich in nutrients and minerals.
The Antartic weather doesn't allow a lot of life to be there and for that reason its soil has a poor amount of organic content. Besides, the climate there is considered dry and its soils have not enough amount of water.
There are differences related with the rocks under the soil, but actually we have all kind of rocks all over the world, so it is not the most important difference.
