- Conditions for life on Earth
- Appropriate temperature range
- Above 0 degrees, which allows liquid water
- Enzymes
- Require liquid water as a solvent
- Ambient gases
- Carbon dioxide
- For photosynthesis and climate control
- Nitrogen
- For protein synthesis
- Carbon dioxide
- UV Light
- Sunlight
- Provides energy for photosynthesis
- Solar Radiation

- UV Light
- Sunlight
- Provides energy for photosynthesis
- Solar Radiation
- Distance from the sun
- Controls light and temperature levels
- Tilted axix
- Seasonal variations
- Tilted rotation
- Controls the duration of day and night and therefore the range of temperature

- Liquid Water
- Transport
- Water is a solvent in blood and sap. It transports oxygen, carbon dioxide, sugars, waste products
- Heat can be transported in the blood .
- E.g from the core of the body to the skin to increase heat loss
- Special freezing qualities
- Ice floats which keeps cold air separate from the water below
- Prevents lakes from freezing solid in the winter
- Ice floats which keeps cold air separate from the water below
