Question

Which occurrence is NOT part of Earth's Carbon Cycle?

(a) Minerals combine with carbon to make rocks on the ocean floor.
(b) CO₂ is heated and escapes the atmosphere, cooling the Earth's surface.
(c) Continental drift carries rock containing carbon down into the Earth's mantle.
(d) Atmospheric CO₂ dissolves in rainwater.
(e) Rain erodes minerals that flow into the ocean.

Answer 1

The occurrence that is NOT part of Earth's Carbon Cycle is the heating and escape of CO₂ from the atmosphere, cooling the Earth's surface.

Step-by-step explanation:

The occurrence that is NOT part of Earth's Carbon Cycle is (b) CO₂ is heated and escapes the atmosphere, cooling the Earth's surface. The carbon cycle involves the movement of carbon between different reservoirs, such as the atmosphere, land, oceans, and organisms.

This process includes the dissolution of carbon in rocks, the exchange of carbon between the atmosphere and water, carbon storage in the ocean and sedimentary rock, and the release of carbon through respiration and combustion. However, the heating and escape of CO₂ from the atmosphere does not occur naturally as part of the carbon cycle.
