Which process releases carbon dioxide into the atmosphere?

Respiration

Explanation

Biological process of organisms releasing CO2 as a byproduct.

What is the process by which plants release water vapor into the atmosphere?

Transpiration

Explanation

Plant's release of water vapor through pores in their leaves.

Which human activity contributes to the release of methane, a potent greenhouse gas, into the atmosphere?

Agricultural activities

Explanation

Agricultural practices like livestock farming produce methane.

What is the primary source of methane emissions from wetlands?

Bacterial activities

Explanation

Microbial decomposition in wetlands produces methane.

Which compound is a major reservoir of carbon in the Earth's crust?

Calcium carbonate

Explanation

Mineral form of carbon stored in rocks and shells.

In the carbon cycle, what role do decomposers play?

They convert organic matter into inorganic carbon

Explanation

Decomposers break down organic matter, releasing inorganic carbon.

Which of the following is a greenhouse gas involved in the carbon cycle?

Methane

Explanation

A potent greenhouse gas produced by various natural and human activities.

Which human activity contributes significantly to the increase in atmospheric carbon dioxide levels?

Driving cars

Explanation

Burning fossil fuels in vehicles releases CO2.

What is the primary function of the oceans in the carbon cycle?

Absorbing carbon dioxide

Explanation

Oceans take up CO2 from the atmosphere, acting as a carbon sink.

#10

What is the primary role of trees in the carbon cycle?

Absorbing carbon dioxide

Explanation

Trees take in CO2 during photosynthesis, storing carbon.

#11

Which atmospheric phenomenon involves the conversion of carbon dioxide into carbonates and their subsequent deposition in the ocean?

Ocean acidification

Explanation

CO2 reacts with seawater forming carbonic acid, leading to ocean pH decrease.

#12

What is the primary source of carbon dioxide in the atmosphere?

Burning fossil fuels

Explanation

Combustion of fossil fuels releases CO2 into the atmosphere.

#13

Which biome acts as a significant carbon sink, storing large amounts of carbon?

Rainforest

Explanation

Rainforests absorb CO2 from the atmosphere and store it.

#14

Which gas is a significant component of the Earth's early atmosphere and played a role in the formation of carbon compounds?

Hydrogen

Explanation

Hydrogen was abundant and participated in early carbon chemistry.

#15

What is the term for the process of converting atmospheric nitrogen into a form that plants can use?

Nitrogen fixation

Explanation

Conversion of atmospheric nitrogen into plant-usable compounds.

#16

What is the term for the process of converting organic carbon into inorganic carbon through combustion?

Combustion

Explanation

Burning organic matter releases CO2 and other byproducts.

#17

Which component of the Earth system plays a crucial role in regulating the balance of carbon dioxide in the atmosphere?

Hydrosphere

Explanation

Oceans and other water bodies absorb and store CO2.
