Study Notes
Water Cycle Key Concepts
- Evaporation: Transition from liquid to gas where water gains thermal energy.
- Condensation: Conversion of gas to liquid where water loses thermal energy.
- Precipitation: Water, in solid or liquid form, falls to Earth (e.g., rain, snow).
- Runoff: Water that flows over the Earth's surface following precipitation and snowmelt.
- Collection: Accumulation of water in bodies like rivers, lakes, and oceans.
Water Survival Facts
- A person can survive without water for only a few days.
- Humans can live over a month without food.
Importance of Water in Organisms
- Water is essential for transporting substances to tissues and organs, occurring solely within cells.
- Both plants and animals primarily consist of water.
Water Composition in Humans
- Over half of the human body is composed of water.
Groundwater and Aquifers
- Groundwater: Water that infiltrates the soil, filling cracks in rocks and serving as a source for springs and wells.
- Aquifer: Saturated loose rock or soil that holds groundwater.
Changes of State in Water
- Melting: Changes from solid to liquid when gaining thermal energy.
- Sublimation: Transitions from solid to gas without becoming liquid, occurring with added thermal energy.
- Freezing: Changes from liquid to solid when losing thermal energy.
- Deposition: Conversion from gas to solid when a gas loses thermal energy.
Water Cycle Mechanics
- Water Table: Depth where rock and soil are saturated with water; marks the upper level of aquifers.
- The water cycle is a continuous natural process where water circulates through different states above, on, and below Earth's surface.
Water Molecule Structure
- A water particle consists of two hydrogen atoms and one oxygen atom, resembling Mickey Mouse ears with the oxygen atom as the larger central portion.
