EARTH ENERGY: Greenhouse Effect

Front

What is the greenhouse effect?

Back

The greenhouse effect is a natural process where certain gases in the Earth's atmosphere trap heat, keeping the planet warm enough to support life.

Front

What gases are considered greenhouse gases?

Back

Greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor.

Front

How does increased CO2 affect the atmosphere?

Back

Increased CO2 levels warm the atmosphere, contributing to climate change.

Front

What human activities contribute to greenhouse gas emissions?

Back

Human activities such as burning fossil fuels, deforestation, and industrial processes contribute to greenhouse gas emissions.

Front

What is the primary source of carbon dioxide emissions?

Back

The primary source of carbon dioxide emissions is the burning of fossil fuels for energy.

Front

What is the role of agriculture in greenhouse gas emissions?

Back

Agriculture contributes to greenhouse gas emissions through practices like livestock production, rice cultivation, and the use of fertilizers.

Front

What is the difference between renewable and non-renewable energy sources?

Back

Renewable energy sources can be replenished naturally (e.g., solar, wind), while non-renewable sources (e.g., coal, oil) are finite and will eventually deplete.

Front

What is the impact of deforestation on the greenhouse effect?

Back

Deforestation increases greenhouse gas levels by reducing the number of trees that can absorb CO2.

Front

What is the significance of the year 1960 in climate data?

Back

The year 1960 marks a significant increase in the measurement of atmospheric CO2 levels, indicating a trend of rising temperatures.

Front

What is carbon monoxide and why is it not a greenhouse gas?

Back

Carbon monoxide (CO) is a gas produced by burning fossil fuels, but it does not trap heat in the atmosphere like greenhouse gases do.
