Question

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

Answer 1

The answer is D

Step-by-step explanation:

When absorbed energy is released back into space, Earth cools. Many factors, both natural and human, can cause changes in Earth's energy balance, including: Variations in the sun's energy reaching Earth. Changes in the reflectivity of Earth's atmosphere and surface.
