Write a paragraph to explain why Earth has the ideal conditions for life to exist.

• The Sun provides light energy for photosynthesis, which is the basis of most food chains.
• The Sun provides heat energy, which maintains Earth's temperature within a range suitable for liquid water and biological processes.

7)

Earth is in the habitable zone around the Sun, allowing for the presence of liquid water, which is crucial for all known life forms. Its atmosphere contains oxygen for respiration and a suitable mix of gases that trap enough heat to maintain a stable temperature, while also protecting from harmful solar radiation. The Earth's magnetic field further shields the planet from dangerous solar winds.
