Slow carbon cycle

Question 1

Carbon sequestration

Answer 1

Refers to long term sinks accumulating that are not released back into global carbon system for millions of years
Describes the transfer of carbon from atmosphere into storage of plants, soil and oceans

Question 2

Terrestrial

Answer 2

Plants capture co2 from atmosphere and store it as carbon in their stems and roots

Question 3

Geologic

Answer 3

Humans can capture co2 and inject it underground
Oceans also sequester carbon by absorbing it and within a few months the carbon sinks to the ocean depths
Take thousands of years to re appear

Question 4

extra

Answer 4

importance of carbon sequestration differs to fossil fuel combustion in that sequestration transfers carbon in the form of carbon dioxide from the atmosphere and oceans to be stored in solid or liquid form in the biosphere, lithosphere or hydrosphere stores. Whereas fossil fuel combustion is important in transferring carbon from the biosphere and lithosphere stores into the atmosphere, thus reducing the magnitude of the initial stores and increasing the magnitude of the latter.

Question 5

Fossil fuels

Answer 5

Carbon in fossil fuels is sequestered only until burn them through combustion

Question 6

combustion

Answer 6

This is because carbon dioxide is released in the burning of hydrocarbons which contributes to climate change and global warming. The extra carbon dioxide in the air acts as a greenhouse gas and effectively traps heat within the Earth’s atmosphere.
