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.
