Question

In the carbon cycle, carbon molecules are exchanged between the natural carbon reservoirs of rocks, soil, plants, fossil fuels, and the ocean. Which of the following is NOT an important exchange between

two reservoirs?
А
from the atmosphere to the hydrosphere, in which gaseous carbon dioxide dissolves into the oceans
B
from the atmosphere to fossil fuels, in which gaseous carbon dioxide forms minerals at Earth's surface
с
from the hydrosphere to fossil fuels, in which ocean sediments are compressed into rock on the ocean floor
from fossil fuels to the atmosphere, in which emissions from cars and industry release gaseous carbon dioxide

Answer 1

In the carbon cycle, carbon molecules are exchanged between various natural reservoirs. Option B, from the atmosphere to fossil fuels, is not an important exchange.

Step-by-step explanation:

In the carbon cycle, carbon molecules are exchanged between several natural reservoirs. Let's evaluate each option:

From the atmosphere to the hydrosphere: This is an important exchange as gaseous carbon dioxide dissolves into the oceans, contributing to ocean acidification.

From the atmosphere to fossil fuels: This exchange doesn't occur. Fossil fuels are formed from the remains of ancient plants and animals, and not directly from gaseous carbon dioxide.

From the hydrosphere to fossil fuels: This exchange also doesn't occur. Fossil fuels are formed from the remains of ancient plants and animals, and not directly from ocean sediments.

From fossil fuels to the atmosphere: This is an important exchange as emissions from cars and industry release gaseous carbon dioxide, contributing to climate change.

Based on the above evaluations, option B, from the atmosphere to fossil fuels, is NOT an important exchange.

Answer 2

FOSSIL FUELS FORM. After millions of years underground, the compounds that make up plankton and plants turn into fossil fuels. Plankton decomposes into natural gas and oil, while plants become coal. Today, humans extract the
