Water Distribution

Today we are going to Review Freshwater, Salt Water and how we access our water.

​

Pay Attention these questions will be on the test​

For many people in Utah, lakes are the largest body of water they experience. 

​

Huge Mass of Ice that moves slowly over land

Can form on Mountainsides and move through valleys

Form when snow builds up and presses together​

​​Glaciers

​

Ribbon-like Body of water that flows downhill because of gravity. Can be wide & deep or shallow & narrow

Has a starting point called a headwater​, can start from rain snowmelt groundwater coming to the surface or form from a lake.

​​River

Huge Body of water that covers 71% of the Earth's Surface

The ocean is one body of water but has been divided into 5 regions: Pacific, Atlantic, Indian, Arctic

Ocean collects water from rivers flowing into it.​

​​Ocean

​

Body of Water surrounded by land.

Water enters the lake from rain, snow, melting ice, streams/rivers, groundwater.

Has an outlet meaning the water can also leave by a river or other means.​

Open Lake

​Water that is in the ground in the spaces between dirt, sand, and pebbles, and in cracks in rocks. Fills empty spaces underground. 

Created from rain, snowmelt, water draining from sprinklers – anything that causes water to go into the ground. 

Can be removed from ground through wells. Very important in dry, desert climates. 

Provides source of water for rivers and streams. 

​​Groundwater

​

​Water storage that is manmade. 

Usually formed by building a dam across a river or controlling the outlet of a natural lake. The amount of water in and out is controlled. 

Used to provide water in case of drought and control flooding.

​​Reservoir

​

​Body of water surrounded by land. 

Water enters the lake from rain, snow, melting ice, streams/rivers, groundwater. 

Does NOT have an outlet for the water to leave other than evaporation. When the water evaporates, it leaves behind salts and minerals that were dissolved in the water. 

​​Closed Lake

​Thick layer of ice and snow over a large area, fewer than 50,000 square kilometers (19,000 square miles); it’s called an ice sheet if it’s larger than that. 

Usually found at North and South Poles. These are called polar ice caps.

Forms when snow builds up and gets pressed together. Are slightly dome-shaped. 

Most living things can’t live on an ice cap, but many animals live around the ice cap borders (edge).

​​Ice Caps

​

​The atmosphere is the layer of gases that surround our planet. The gases have water evaporation in them.

​​Atmosphere

​land consisting of marshes or swamps; saturated land

​​Wetlands

​Anything that is a live, humans and animals contains some form of water in it. Human Bodies are 70% water.

​​Living Thing

​

​Plants contain water in them as well as use Water sources to grow.

​​Plants

​

​.09% of water is in the atmosphere

96.5% of water is in the ocean

1.73% is in snow, glaicers and ice sheets

.008% living things

.64% is in rivers & lakes

.75% is in ground water​
