After its formation, Earth was extremely hot. Which of these contributed to the cooling of Earth?

A. Carbon moved from the biosphere to the geosphere when photosynthetic organisms died and were buried by sediment.

B. Carbon moved from the hydrosphere to the geosphere when carbon moved from the oceans to sediment on the ocean floor

C. Carbon dioxide moved from the geosphere to the atmosphere when lightning struck and burned fossil fuels

D. Carbon dioxide moved from the atmosphere to the biosphere when photosynthetic organisms began to absorb it

The correct answer is option D. "Carbon dioxide moved from the atmosphere to the biosphere when photosynthetic organisms began to absorb it".

Explanation:

One of the factors that contributed to extremely hot conditions on Ancient Earth was the high concentration of carbon dioxide in the atmosphere. Carbon dioxide is a greenhouse gas, and it trap the heat of the sun in the atmosphere. Photosynthetic organisms contributed to Earth's cooling by moving carbon dioxide from the atmosphere to the biosphere. Photosynthetic organisms such as algae and plants take carbon dioxide from the atmosphere to synthesize its own food, this helped to reduce carbon dioxide concentration and contributed to ancient Earth cooling.

the answer would be d
