Answer:

Because coal burns at a slow rate for a long time, it's more efficient as an energy source than other fossil fuels.

But it is weird.

: )

Explanation:

It is weird to have so many coal deposits in cold regions of the earth because there is very less temperature and coal needs a high temperature to be produced.

Coal is a more effective energy source than other fossil fuels because it burns slowly and continuously.

Due to climate change and crustal plate tectonics, which occasionally pushed ancient continental masses through subtropical and even tropical regions, substantial coal deposits can be found in areas that presently have arctic or subarctic climates.

Other problems with mining minerals in Antarctica include the fact that weathering processes that concentrate minerals in other regions of the world don't occur there. The continent is frozen and has been for millions of years, with little to no liquid water moving.

Therefore, because there is relatively little temperature and coal needs a high temperature to be created, it is strange to have so many coal resources in chilly places on the planet.

When there is a large and nonvolcanic mountain belt such as the Himalayas, this is associated with continent-continent collisions.

When continents collide, it would be pieces of the earth's crust colliding so there wouldn't be any opening that leads to lava seeping out from the Mantle. The result would therefore be nonvolcanic.

With the crust being so thick, the result will also be thick crusted much like the Himalayas which is the result of the Indian and Eurasian plates colliding.
