30 Terms

1
Water Pollution
Contamination of water bodies, affecting ecosystems and human health.
New cards
2
Water Accessibility
The availability of water resources to meet human needs.
New cards
3
Hydrological Cycle
The circulation and conservation of Earth's water through evaporation, condensation, and precipitation.
New cards
4
Evaporation
The process by which water changes from a liquid to a gas, primarily driven by the sun's heat.
New cards
5
Transpiration
The process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere.
New cards
6
Cohesion
The property of water that allows water molecules to stick together due to hydrogen bonding.
New cards
7
Adhesion
The ability of water to cling to other substances, important for processes like water transport in plants.
New cards
8
Capillary Action
The ability of water to travel against gravity through thin spaces, such as plant roots.
New cards
9
Non-consumptive Water Use
Water usage that does not permanently remove water from a source, even if it becomes contaminated.
New cards
10
Consumptive Water Use
Water usage where the water does not return to the source after use.
New cards
11
Blue Water Footprint
The amount of surface water and groundwater required to produce an item.
New cards
12
Green Water Footprint
The amount of rainwater required to produce an item.
New cards
13
Grey Water Footprint
The amount of freshwater required to dilute wastewater generated in manufacturing.
New cards
14
Run-off
Water that flows over the ground surface, often leading to rivers and oceans.
New cards
15
Infiltration
The process of water sinking into the ground.
New cards
16
Interception
Water caught on vegetation before it reaches the ground.
New cards
17
Surface Detention
Water that is held on the surface of the land.
New cards
18
Climate Change
Long-term alteration of temperature and typical weather patterns in a place, affecting water resources.
New cards
19

two biggest concerns about water resources

water pollution and water accessibility

New cards
20

four categories of human impact on water?

changes to earth’s surface

changes to earth’s climate/atmospheric pollution

withdrawals diversion for human use

excess pollution

New cards
21

4 important properties of water

Cohesion

moderation of temperature

ice floats on liquid water

water as a solvent

New cards
22

who are the biggest users of water

Non-consumptive Uses: Nonconsumptive uses of water: water may be contaminated but is still available to humans. Used in homes, industries, and
electric power production


Consumptive uses of water: the applied water does not return to the
water resource. It percolates into the ground or evapotranspires

New cards
23

what is water and used in the eastern vs western USA

Eastern US - most water is used
for energy production,
manufacturing


Western US - most water is used for
irrigation

New cards
24

what drives the hydrological cycle

driven by gravity and solar energy

New cards
25

Define transport

The movement of water through the atmosphere, specifically, from over the oceans over land.

New cards
26

Define condensation

The transported water vapor eventually condenses, forming tiny
droplets in clouds.

New cards
27

precipitation

The primary mechanism for transporting water from the
atmosphere to the surface of the earth.

New cards
28

what is ground water

beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations. It is stored in and moves slowly through geologic formations called aquifers

New cards
29

overland

WATER FLOWS OVER THE GROUND TO RIVERS AND STREAMS

New cards
30

what is evapotranspiration

WATER LOST BACK TO THE ATMOSPHERE BY EVAPORATION AND TRANSPIRATION IS KNOWN COLLECTIVELY
