Answer:
a. plants are preserved as fossils
Explanation:
Through the passing of time, the dead bodies like plants or animals rest in soil, and the cover by different particles, with the time they can be compressed and form a soil layer. If the environment condition changes they get caught in one soil layer. If this process is repeated constantly, so a new soil layer will be formed. So passing the time, different soil layers will have different animals or plants. With the help of isotopes, the scientist can determine the years of each layer.
The correct answer is C. The burning of fossil fuels.
Explanation
The carbon cycle is a cycle in which carbon interacts with the biosphere, the lithosphere, the hydrosphere, and the Earth's atmosphere. Knowledge about this carbon circulation makes it possible to appreciate human intervention in the climate and its effects on climate change. This cycle makes life on Earth possible because the plants consume carbon dioxide, however, the balance of this cycle has been altered by the massive use of fossil fuels such as oil, gasoline, and gas. This alteration causes the atmosphere to deteriorate causing the sun's rays to directly penetrate the earth, on the other hand, it causes the greenhouse effect to increase, causing the earth's temperature to rise. So, the correct answer is C. The Burning of fossil fuels.
