Warm Up 1. How old is the water you drank this morning? 2. Give an example of cohesion, adhesion, surface tension and buoyancy.

Homework Assignment 1. Refer to pages 26C and 29C and illustrate your own version of groundwater. You must include the following labels: water table, permeable rock, impermeable rock, river, aquifer, lake, well. It must be colorful and take up a page in your notebook (p.22)!

TLW describe the distribution of water on earth, including the %, phase and availability by taking notes w/a tree map, creating an illustration taking an exit ticket quiz

Big Idea Continents on earth surrounded by water. Deep oceans cover more than 2/3 of Earth’s surface. Water can also be found underground! KEY WORDS: hydrosphere, salinity, glacier, groundwater, aquifer, wetland, watershed, river, tributaries, lake

The Hydrosphere “Where is all the water?” You must know the percentages of saltwater, freshwater, frozen water, underground water and surface water.

The Hydrosphere Hydrosphere: the part of Earth that contains water 97% of Earth’s water is salt water 97% of Earth’s water is salt water Only 3% is fresh water: ( 30% groundwater, 68% frozen, 2% on surface) Only 3% is fresh water: ( 30% groundwater, 68% frozen, 2% on surface)

The Global Ocean Ocean cover 71% of Earth’s Surface (about 2/3) Ocean cover 71% of Earth’s Surface (about 2/3) What are the four major oceans? What are the four major oceans? Which is the largest and deepest? Which is the largest and deepest? All oceans connect as one large world ocean All oceans connect as one large world ocean Ocean water is salty due to the dissolved salts in the water. Ocean water is salty due to the dissolved salts in the water. The saltiness of water is known as SALINITY The saltiness of water is known as SALINITY

Salinity Salinity is concentration of salts in a liquid, such as water. Salinity is concentration of salts in a liquid, such as water. Increase salt; Increase salinity Increase salt; Increase salinity Ocean water has a 3.5% salinity Ocean water has a 3.5% salinity What factors could change the salinity of the oceans? What factors could change the salinity of the oceans?

Freshwater Resources Most freshwater is frozen at the polar ice caps!! Most freshwater is frozen at the polar ice caps!! Glaciers are masses of ice and snow that move slowly over the Earth’s surface. Glaciers are masses of ice and snow that move slowly over the Earth’s surface.

Where’s the water?

The great lakes are the largest freshwater System on earth. They contain 84% of North America’s surface freshwater and 21% of the world’s surface fresh water supply. Only the polar ice caps contain more fresh water.

Freshwater Resources 1/3 of Earth’s freshwater is groundwater!! 1/3 of Earth’s freshwater is groundwater!! Groundwater forms when water moves through soils and sediment and collects in spaces underground. Groundwater forms when water moves through soils and sediment and collects in spaces underground. An aquifer is a rock layer that stores water in the spaces between the rock and allows water to flow through it.
