Term
H2O is a compound that can exist as a
Definition
liquid, solid or a gas.
Term
One water molecule has
Definition
two hydrogen atoms and one oxygen atom
Term
Fresh water is water that is not
Definition
salty and has little or no taste, color, or odor.
Term
Freshwater can be found in
Definition
rivers, many lakes, underground in aquifers, and in the form of ice.
Term
All precipitation that falls to the surface of Earth is
Definition
fresh water.
Term
Salt water is water that contains
Definition
dissolved salts and other minerals
Term
Salt water is not for human consumption. Meaning humans cannot
Definition
drink saltwater or use saltwater.
Term
The salt in the Earth’s oceans comes from
Definition
minerals dissolved from rocks as water moves toward the oceans.
Term
Most of the water on the Earth is
Definition
saltwater. Only a small amount is fresh water.
Term
e majority of the Earth's surface is covered with
Definition
water.
Term
The water on Earth is not evenly distributed. Most of it is
Definition
unsuitable for drinking.
Term
The total volume of water on the Earth is
Definition
326 million cubic miles.
Term
97% of Earth’s water is in the oceans as
Definition
salt water.
Term
3% of Earth’s water is
Definition
fresh water.
Term
2% of Earth’s water is
Definition
frozen in ice caps and glaciers.
Term
Less than 1% (0.65%) of Earth’s water is fresh water in
Definition
lakes, streams, groundwater, and water vapor in the atmosphere.
Term
H2O (water) cycles through states of matter in the atmosphere based on
Definition
atmospheric conditions.
Term
The water cycle has three stages:
Definition
precipitation, evaporation, and condensation
Term
The process in which water changes from liquid to vapor is called
Definition
evaporation.
Term
Transpiration is the evaporation of water from
Definition
plants.
Term
Condensation is the process in which water vapor in the atmosphere becomes
Definition
liquid.
Term
When water falls from clouds as liquid or solid it is called
Definition
precipitation.
Term
The cycling of water in and out of the atmosphere plays an important role in determining
Definition
climatic patterns.
Term
Water evaporation from the surface of the earth
Definition
rises and cools, condenses into rain or snow, and falls again to the surface.
Term
Rain, snow, sleet, and hail are all forms of
Definition
precipitation.
Term
Rain falls to the ground and collects in streams that flow into rivers, that eventually lead to the
Definition
world’s oceans.
Term
The water, which is a solvent, falling on land collects in
Definition
rivers and lakes, soil, and porous layers of rock, and much of it flows back into the ocean.
Term
Most rain falls on the Earth’s oceans because most of Earth is
Definition
covered by water.
Term
Most of the water that evaporates on Earth, evaporates from the The
Definition
ocean
Term
salt and minerals are left behind in the
Definition
ocean
Term
Salts have become concentrated in the sea (compared with freshwater) because the sun's heat causes the evaporation of water, leaving
Definition
the salts and minerals behind.
Term
If LESS fresh water flowed into the oceans in the future, the world’s
Definition
oceans would become more salty.
Term
If MORE fresh water flowed into the world’s oceans, they would become
Definition
less salty.
Term
2% of Earth’s total water is
Definition
frozen in ice caps and glaciers.
Term
Less than 1% (0.65%) of Earth’s water is fresh water in
Definition
lakes and streams, groundwater, and water vapor in the atmosphere.
Term
Most of the freshwater on Earth is located in
Definition
glaciers and ice caps.
Term
Groundwater is water that occurs as a liquid resource that is dispersed through
Definition
innumerable holes, pores, fractures and cavities in bodies of rock or sediment.
Term
Porous means
Definition
the rock has many pores and things can easily penetrate it.
Term
When something is impermeable then water cannot
Definition
easily penetrate it.
Term
An aquifer is an
Definition
underground layer of permeable rock or sediment that contains water.
Term
A layer of impermeable rock is located immediately BELOW
Definition
an aquifer.
Term
A layer of permeable rock is located ABOVE
Definition
an aquifer.
Term
Aquifers have rocks that have very large pores in them. This allows them to hold
Definition
large amounts of water.
Term
How do we get water out of aquifers?
Definition
Pumps pull the water up from the aquifer.
Term
What is saltwater intrusion?
Definition
Saltwater from the ocean entering a fresh water aquifer.
Term
A geyser is formed when
Definition
heat from magma heats water and forces it to shoot out of the ground.
Term
Water in an artesian spring THAT flows naturally out of the ground because of
Definition
pressure.
Term
Springs are naturally formed locations where ground water comes to the surface and wells are
Definition
man-made structures designed to bring water to the surface from deep underground.
Term
Human have access to use less than one percent of the water on Earth for
Definition
drinking and personal hygiene.
Term
This less than one percent is also used for
Definition
agriculture, fisheries, transportation, heating and cooling, manufacturing, and many other purposes.
Term
Unless humans use freshwater wisely, rivers, lakes, and groundwater can become
Definition
depleted or polluted, and unavailable or unsuitable for life.
Term
Much of our municipal and industrial water comes out of
Definition
the ground.
Term
Many countries on Earth are experiencing a
Definition
fresh water shortage.
Term
Water is a valuable
Definition
natural resource.
Term
Air pollution causes
Definition
acid rain.
Term
Rainwater picks up particles and gases when it falls through the air.If the air is polluted, the rainwater becomes
Definition
polluted too.
Term
The acid rain can kill
Definition
fish and plant life in lakes, rivers, and ponds.
Term
Where do most people get their drinking water?
Definition
Underground aquifers.
Term
The Floridian Aquifer stretches from
Definition
Florida and South Carolina.
Term
Why is the Floridian Aquifer important to ME?
Definition
Most residents of Georgia get their drinking water from the Floridian Aquifer.
Term
Why is it unwise to drink from streams and rivers?
Definition
Microscopic plants and animals live in the water and can cause humans serious illnesses and can lead to death.
Term
How do cities clean the water that comes out of your house?
Definition
Cities use wastewater treatment plants to clean the water.
Term
How does dumping toxic material in one state hurt people in another state?
Definition
The material can sink underground and enter the underground aquifers.
Term
Why don’t more nations use ocean water for farming and human consumption?
Definition
Cost of purifying it to become fresh is too expensive.
Term
The Water Cycle -
Definition
Continuous movement of water on Earth, through the atmosphere and in the living things on Earth.
Term
deposition –
Definition
the part of the erosion process in which sediment is placed in a new location
Term
erosion –
Definition
the process in which weathered particles are picked up and moved from one place to another
Term
gravity –
Definition
the natural force that tends to cause physical things to move toward each other - the force that caused things to fall toward Earth
Term
composition -
Definition
the nature of something's ingredients or constituents; the way in which a whole or mixture is made up
Term
conservation -
Definition
preservation, protection, or restoration of the natural environment, natural ecosystems, vegetation, and wildlife
Term
evaporation -
Definition
process in which water changes from liquid to vapor
Term
condensation -
Definition
process in which vapor in the atmosphere becomes liquid
Term
precipitation –
Definition

Definition
will not allow water to pass through
Term
permeable -
