Coal, a fossil fuel made from the remains of swamp plants, has been found in Antarctica. Which of the following is the most reasonable explanation for how this is possible when 98% of Antarctica is now covered in ice?
The coal was transported by animals that ate the swamp plants.
The climate of Antarctica has become milder due to its closeness to the ocean.
The climate of Antarctica was probably much warmer in the past than it is today.
The coal was transported through large convection currents and uplift in the mantle.

The climate of Antarctica was probably much warmer in the past than it is today.

Explanation:

There are little things living there now. Coal takes millions of years to form. There must have been much more living things there in the past (when it was warmer) to make coal.
