GEO 1200 Lecture Notes - Lecture 2: Latent Heat, Hydrosphere, Nimbostratus Cloud
Document Summary
Water (h20) is a chemical compound of hydrogen and oxygen. Positive and negative charges attract so water molecules stick together. Latent heat energy is released and absorbed as it changes from one state to another. Water exists in the air in the form of water vapor clouds, fog, and precipitation. The hydrosphere- the realm of water in all its forms and the flow of water among ocean, land, and atmosphere. Ice sheets and glaciers- second highest 2. 15% most fresh water on earth exists in frozen form. The global flow of water to and from oceans, land and atmosphere. Water moves by evaporation and runoff- underground movement. Water evaportates, rises to atmosphere, moisture forms clouds- cools off, water return to. Earth"s as rain (too heavy) then it rains, snows, sleet, and hails. Humidity- the amount of water vapor presents in the air (dependent on the air temperature) Warm air can hold more vapor than cold air.
