Which piece of evidence did alfred wegener's original theory of continental drift have access to?

a. seafloor spreading at mid-ocean ridges

b. reversing paleomagnetism in rocks on the ocean floor

c. evidence of ancient tropical swamps in cold regions of north america

d. a seafloor that was geologically active with earthquakes, volcanoes, and mountain chains

C. evidence of ancient tropical swamps in cold regions of North America

Explanation:

The crucial point for the development of the Continental Drift theory, which in its essence means the movement of continents, or moving plates, is the realization that the earth is not static. Then Wegener realized that the coast of Africa was contoured to fit the coast of South America. In addition, he found evidence of ancient tropical exchanges in cold North American regions.

Another trace that supports the theory was the discovery of fossils of animals of the same species on different continents, as it would be impossible for these animals to have crossed the Atlantic Ocean, the only explanation being that in the past the two continents were together.

i think the answer would d

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
