Answer 3

Conditions for Life on Earth

1. Suitable Temperature Range: - Life on Earth requires a suitable temperature range. The average temperature on Earth is approximately 59 degrees Fahrenheit (15 degrees Celsius).

2. Presence of Water: - Water is essential for life. It is involved in various biological processes and is a universal solvent. Approximately 60% of the human body is water, and it is crucial for the survival of all known forms of life.

3. Atmosphere: - The Earth's atmosphere, composed mainly of nitrogen (78%) and oxygen (21%), is essential for life. It provides the necessary gases for respiration and protects the Earth from harmful radiation.

4. Suitable Atmospheric Pressure: - The atmospheric pressure on Earth is suitable for life. The pressure at sea level is about 14.7 pounds per square inch (psi) or 101.3 kilopascals (kPa).

5. Presence of Organic Molecules: - Organic molecules, such as amino acids and nucleotides, are essential building blocks for life. They are found in various forms on Earth and are crucial for the formation of living organisms.

6. Energy Source: - Life on Earth requires an energy source. The Sun provides the primary source of energy for most life forms through the process of photosynthesis.

7. Suitable Radiation Levels: - The Earth's magnetic field and atmosphere protect the planet from harmful solar and cosmic radiation, creating suitable radiation levels for life.

8. Stable Climate: - A stable climate is essential for life. Earth's climate has been relatively stable over long periods, allowing life to thrive.

9. Protection from Harmful Cosmic Events: - Earth's magnetic field and atmosphere provide protection from harmful cosmic events, such as solar flares and cosmic rays, which could be detrimental to life.

10. Suitable Gravity: - The Earth's gravity, approximately 9.8 m/s², is suitable for life as we know it.

These conditions collectively create a habitable environment for life on Earth.
