Topic 1 - Global Systems

Question 1

Carbon Cycle

Answer 1

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

Question 2

Volcanic Eruptions

Answer 2

Release large amounts of carbon dioxide into the atmosphere

Question 3

Carbon Sequestration

Answer 3

In the ocean, or marine environment, phytoplankton and other marine organisms take in carbon through photosynthesis, CO2 combines with the water and forms calcium carbonate shells.

Question 4

Cellular Respiration

Answer 4

Animals eat the plants and take in the O2 to power cellular respiration, and then release CO2 into the atmosphere

Question 5

Photosynthesis

Answer 5

Plant cells absorb solar energy, carbon dioxide, water, and convert them into oxygen, water, and glucose (energy)

Question 6

Decompisition

Answer 6

When organisms die, their organic matter becomes available for decomposition by decomposers.

Question 7

Fossilisation

Answer 7

The burial and transformation of organic matter into fossil fuels such as coal, oil, and natural gas.

Question 8

Unavailable Carbon

Answer 8

Removed carbon from the carbon cycle as its transformed into fossil fuels.

Question 9

Combustion of fossil fuels

Answer 9

Fossil fuels are burned for energy production, transportation, industrial purposes, and heating.

Question 10

Limestone and weathering

Answer 10

Calcium carbonate reacts with acids found in rainwater and soil

Question 11

Deforestation and fires

Answer 11

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
