GEOG 101 Lecture Notes - Lecture 7: Surface Tension, Northern Hemisphere, Heat Capacity
Document Summary
Water lost from the system is replenished by outgassing. Ways in which water is lost from the system. There is more land mass northern hemisphere and so land and water hemispheres may be seen. Water exists in three states on earth. Average residence time in the troposphere about 10 days. Ice is less dense than liquid water. Ice is a good conductor of heat. Water aggregates in droplets rather than spread out over a surface as a thin film. Plants can move water (and dissolved nutrients) from their roots to their leaves (capillary action) Water can form waves on lakes and oceans. Humidity: the amount of water vapour in the air. Absolute humidity: the mass (g) of water vapour per unit volume (m3) of air. Specific humidity: the mass (g) of water vapour per unit mass (kg) of air .
