How does the distribution of the world's major coal reserves support the theory of plate tectonics?(1 point)
Tanya [424]

B) Around 300 million years ago, the regions where coal formed were located in tropical climates that were partially submerged on the coasts

Explanation:

The distribution of the world's major coal reserves supports the the theory of plate tectonics because the regions where they formed were in tropical climates around 300 million years ago.

Coal is a fossil fuel used to produce energy when burnt.

They are formed in tropical swamps where there is luxuriant plants life.

To form a coal, a terrain such as swamp must have rich plant life. The plant is rapidly buried and cut off from the oxic environment. Further burial under heat and pressure transforms the plant matter into coal.

  • The major reserves of coal in the world today is found in Europe and North America
  • These are temperate regions whose conditions do not favor the formation of coal.
  • Those regions must have moved from around the equator to their present day position.
  • The coal formed when they were much closer to the equator around 300 million years ago.
