DOL 12/12 Earth's Ability to Support 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

Why is Earth's atmosphere important for life?

Back

Earth's atmosphere contains a balanced mix of gases, including oxygen and carbon dioxide, which are essential for life and help regulate the planet's temperature.

Front

What role does Earth's magnetic field play in supporting life?

Back

Earth's magnetic field protects the planet from harmful solar radiation, which can be detrimental to living organisms.

Front

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

Back

Earth's distance from the Sun is just right to allow for liquid water to exist, which is crucial for life.

Front

What is the primary reason Venus cannot support life?

Back

Venus orbits the sun at a closer distance than Earth, leading to extreme temperatures and a thick atmosphere that prevents water from existing.

Front

What is the significance of liquid water for life on Earth?

Back

Liquid water is essential for all known forms of life, serving as a solvent for biochemical reactions and a medium for nutrient transport.

Front

How does the composition of Earth's atmosphere differ from that of Venus?

Back

Earth's atmosphere has a balanced mix of gases, while Venus has a thick atmosphere dominated by carbon dioxide, with very little oxygen.

Front

What is the role of carbon dioxide in the greenhouse effect?

Back

Carbon dioxide traps heat in the atmosphere, contributing to the greenhouse effect and helping to maintain Earth's temperature.

Front

Why is Earth considered unique in the Solar System?

Back

Earth is the only planet known to support life, due to its suitable distance from the Sun and its life-sustaining atmosphere.

Front

What are the consequences of a planet being too close to the Sun?

Back

A planet that is too close to the Sun may experience extreme heat, making it difficult for liquid water to exist and life to thrive.
