<span>The observation of rocks in several mountainous belts that today are separated by oceans provides evidence of continental drift. Continental drift is the displacement of continental masses relative to each other. The Appalachian mountain belt in eastern North America ends off the coast of Newfoundland. Mountains of the same age with rocks and similar structures are found in the British Isles and Scandinavia, when these land masses come together, the mountain ranges form an almost continuous belt.</span>

Answer:

boron and carbon isotope, Phytane, Ice cores, Corals, Lake and ocean sediments etc.

Explanation:

Drillings in ice cores like within ice sheets of Greenlands, Antarctica started in 1956. Collecting core samples of 4 and a half inches and use of molecules of water O 16 and 18 that helps to determine the past atmospheric carbon.

Corals, skeletal rings have bands of paleo-climatological information and as their body is made of the calcium carbonates these limes creating organisms help to determine the atmospheric concentration of carbon on prehistoric earth.
