ENVS1

• Physiological Solvent
• Transport of water
• Temperature control
• Anomolous expansion on freezing
• High specific heat capacity
• Provision of aqauatic habitats

Temperature:

• Most areas upon earth are over 0 degrees C which means it can support liquid water .
• Enzymes need water as a solvent as at higher tempratures they can denature.
• Some organisms can survive tempretures higher than this an example of these are thermophilic bacteria.

• Carbon Dioxide (Photosynthesis and climate control)
• Nitrogen (Protein synthesis)

• Sunlight-Energy for photosynthesis
• Heat production when absorbed-The source of energy for the water cycle and climate.
• UV and Ionising radiation.

• Distance from Sun
• Daily Rotation
• Tiltled Axis
• Molten layers beneath the crust
