DOL 12/12 Earth's Ability to Support Life

Front

What is the main reason Earth can support life?

Back

Earth is the only planet in the Solar System capable of supporting life due to its perfect distance from the Sun and the composition of its atmosphere.

Front

Why is Venus often called Earth's twin?

Back

Venus is nicknamed Earth's twin because of its similar size and structure, but it cannot support life.

Front

What effect does Earth's atmosphere have on temperature?

Back

Earth’s atmosphere contains a balanced mix of gases, including oxygen and carbon dioxide, that trap heat through the greenhouse effect.

Front

How does Earth's distance from the Sun affect its ability to support life?

Back

Earth's distance from the Sun allows for a suitable temperature range that supports liquid water, essential for life.

Front

What is the greenhouse effect?

Back

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

Front

What role does water play in supporting life on Earth?

Back

Water is essential for all known forms of life; it serves as a solvent, a temperature regulator, and a medium for biochemical reactions.

Front

Why can't life exist on Venus despite its similarities to Earth?

Back

Life cannot exist on Venus due to its extreme temperatures and thick atmosphere, which is mostly carbon dioxide, leading to a runaway greenhouse effect.

Front

What is the significance of Earth's magnetic field?

Back

Earth’s magnetic field protects the planet from solar radiation and cosmic rays, which can be harmful to living organisms.

Front

How do oceans contribute to Earth's ability to support life?

Back

Oceans regulate temperature, store carbon dioxide, and provide habitat for countless species, playing a crucial role in supporting life.

Front

What gases are primarily responsible for the greenhouse effect on Earth?

Back

The primary gases responsible for the greenhouse effect on Earth are carbon dioxide, methane, and water vapor.
