Topic 1 - Global Systems Carbon🤍

Question 1

Volcanic eruptions

Answer 1

Release large amounts of carbon dioxide into the atmosphere.

Question 2

Carbon sequestration

Answer 2

The process of capturing and storing atmospheric carbon. Plants take in carbon dioxide to use in photosynthesis and store within their tissues (cells). In the ocean, phytoplankton and other marine organisms take in carbon through photosynthesis.

Question 3

Cellular respiration

Answer 3

Organisms take in oxygen then release carbon dioxide into the atmosphere.

Question 4

Photosynthesis

Answer 4

Plant cells absorb solar energy, water and carbon dioxide creating oxygen, water and glucose.

Question 5

Decomposition

Answer 5

Organisms die, their organic matter becomes available to decomposers.

Question 6

Fossilization

Answer 6

Burial and transformation of organic matter into fossil fuel as coal, oil and natural gas.

Question 7

Unavailable carbon and Fossilization

Answer 7

The burial and transformation of organic matter into fossil fuels such as coal, oil, and natural gas. Removes carbon from the cycle as it is transformed into fossil fuels. Once fossil fuels are formed, they remain underground until extracted.

Question 8

Combustion of fossil fuels

Answer 8

When fossil fuels are burnt releasing large amounts of carbon dioxide into the atmosphere.

Question 9

Limestone weathering

Answer 9

Limestone (calcium carbonate) reacts with acids found in rainwater and soil and produces CO2 which is released into the atmosphere.

Question 10

Deforestation and fires

Answer 10

When trees and vegetation are cut down, burned or left to decay, the carbon stored in their tissues and cells is released into the atmosphere as CO2.

Question 11

Interactions with hemispheres

Question 12

Definition

Answer 12

The cycle that transfers carbon through the atmosphere, lithosphere, biosphere and hydrosphere.
