Question

The existence of coal beds in Antarctica indicates that the continent once had

Answer 1

If Antarctica has coal beds, and coal is formed from pressured carbon, then it indicates that Antarctica once had living organisms. Because living things are carbon based.

Answer 2

Answer:

How does the presence of coal on Antarctica indicate a climate change?

 

The discovery of a new coal deposit means people will be able to use this fossil fuel longer.

 

Coal deposits can tell scientists what the composition of the atmosphere was in the past.

 

Coal forms from the remains of plants that lived in tropical swamps millions of years ago.

 

Coal is burned for fuel and it releases carbon dioxide into the atmosphere.

Explanation:

Answer Coal forms from the remains of plants that lived in tropical swamps millions of years ago.

Misplaced fossils are another way scientists can tell the climate of a region has changed. Fossil corals and other marine organisms have been found in abundance in parts of Europe not covered by water. However, these fossils show that a shallow, tropical sea must have once covered this region. Coal deposits in Antarctica also indicate a change in climate. Coal deposits were created when giant plants that lived hundreds of millions of years ago in areas of tropical, swampy forests died and formed layers at the bottom of the swamp.
