The first evidence supporting the theory of continental drift was a. evidence of extinct species on nearby continents b. the fitting together of neighboring continents like jigsaw puzzle pieces c. the fossil evidence of a former tropical climate non-tropical continents d. the existence of coal deposits in similar areas of neighboring continents

The correct answer is option B.

Explanation:

The continental drift theory suggested that all land were all together and drifted because of several changes in the environment.

For example, the west coast of Africa and South America seem to fit all together like are pieces of a jigsaw puzzle.

Thus, the very first evidence about supporting the theory of continental theory.

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."
