SS- Daily Review - Nutrient Cycles and Greenhouse Gases

Front

What is precipitation?

Back

Precipitation refers to any form of water, liquid or solid, that falls from the atmosphere to the Earth's surface, including rain, hail, and snow.

Front

Which process does not return CO2 into the atmosphere?

Back

Photosynthesis does not return CO2 into the atmosphere; instead, it absorbs CO2 to produce glucose and oxygen.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases in the Earth's atmosphere, such as carbon dioxide and methane, that trap heat and contribute to the greenhouse effect, leading to global warming.

Front

What is the greatest cause of harmful levels of carbon in the atmosphere?

Back

Combustion, particularly of fossil fuels, is the greatest cause of harmful levels of carbon dioxide in the atmosphere.

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water evaporates from the Earth's surface, condenses in the atmosphere, and returns as precipitation.

Front

What role does photosynthesis play in the carbon cycle?

Back

Photosynthesis plays a crucial role in the carbon cycle by absorbing carbon dioxide from the atmosphere and converting it into organic matter.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which greenhouse gases trap heat in the Earth's atmosphere, leading to an increase in global temperatures.

Front

Name two major greenhouse gases.

Back

Two major greenhouse gases are carbon dioxide (CO2) and methane (CH4).

Front

How does combustion contribute to climate change?

Back

Combustion releases large amounts of carbon dioxide and other greenhouse gases into the atmosphere, contributing to climate change and global warming.

Front

What is the significance of the water cycle in ecosystems?

Back

The water cycle is essential for maintaining ecosystems as it regulates water availability, supports plant growth, and influences weather patterns.
