Chapter 3 - Overview of Hydrology and Water Supply Flashcards
How much of Earth’s water is freshwater?
2.5%, the rest is oceans
Evaporation
The process where liquid water changes into water vapor (gas)
Condensation
The process where water vapor (gas) changes into water droplets (liquid)
Plant Uptake
Water taken from the groundwater flow and soil moisture
Transpiration
Evaporation of liquid water from plants and trees into the atmosphere
Transportation
The movement of solid, liquid and gaseous water through the atmosphere
Runoff
River, lake, and stream transport of water and transport of ice in glaciers
Precipitation
Water that falls to the earth. Most precipitation falls as rain, but includes snow, sleet, drizzle, and hail.
Groundwater
Underground water flow (aquifers)
Deposition
The process where water vapor (gas) changes into ice (solid), skipping the liquid phase
Sublimation
The process where ice and snow (solid) change into water vapor (gas), skipping the liquid phase
Infiltration
Movement of water into the ground from the surface
Percolation
Movement of water past the soil going deep into the groundwater
Evaporation measuring tool
Hygrometer
What are the factors affecting evaporation?
Temperature: makes it increase
Wind: makes it increase
Humidity: makes it decrease
Surface area: makes it increase
Dissolved salt: makes it increase
