1 Where in the world is water?

2 Georgia Standard S6E3. Students will recognize the significant role of water in earth processes. S6E3. Students will recognize the significant role of water in earth processes. a. Explain that a large portion of the Earth’s surface is water, consisting of oceans, rivers, lakes, underground water, and ice.

3 Essential Question What is the differences between oceans, rivers, lakes, underground water and glaciers(ice)? What is the differences between oceans, rivers, lakes, underground water and glaciers(ice)? What is the difference between salt water and fresh water? What is the difference between salt water and fresh water?

4 What is the ocean? An ocean is a body of saline (salt) water that composes a large part of Earth’s hydrosphere.

21 Essential Question What is the difference between salt water and fresh water? What is the difference between salt water and fresh water?

22 Essential Question What is the difference between salt water and fresh water? What is the difference between salt water and fresh water?Answer: Salt water contains certain amounts of salts while fresh water is water with a dissolved sail concentration of less than 1 per cent. Salt water contains certain amounts of salts while fresh water is water with a dissolved sail concentration of less than 1 per cent.

23 Important Facts About Water The earth's oceans are connected. The earth's oceans are connected. About 70% of the Earth's surface is covered by water. About 70% of the Earth's surface is covered by water. Water is not evenly distributed, and most of it is unsuitable for drinking. Water is not evenly distributed, and most of it is unsuitable for drinking.

24 Where in the world is water? Of all the total volume water on the Earth (1.36 billion km3, or 326 million mi3): Of all the total volume water on the Earth (1.36 billion km3, or 326 million mi3): 97% is in the oceans as salt water, 97% is in the oceans as salt water, 2% is frozen fresh water in ice caps and glaciers, 2% is frozen fresh water in ice caps and glaciers, 1% is fresh water in lakes and streams, groundwater, and water vapor in the atmosphere. 1% is fresh water in lakes and streams, groundwater, and water vapor in the atmosphere.

25 Why Study Water? We can use less than one percent of the water on Earth for drinking and personal hygiene. We also use this fresh water for agriculture, fisheries, transportation, heating and cooling, manufacturing, and many other purposes. We can use less than one percent of the water on Earth for drinking and personal hygiene. We also use this fresh water for agriculture, fisheries, transportation, heating and cooling, manufacturing, and many other purposes. Water dissolves more substances than any other liquid. Wherever it travels, water carries chemicals, minerals, and nutrients with it. Water dissolves more substances than any other liquid.

26 Fact or Fiction? Most of Earth's freshwater is found in streams and lakes. Most of Earth's freshwater is found in streams and lakes. Most of the freshwater on Earth is located in glaciers and ice caps. Most of the freshwater on Earth is located in glaciers and ice caps.

27 Fact or Fiction? Almost 70% of the Earth's surface is covered by water. Almost 70% of the Earth's surface is covered by water. Almost 70% of the Earth's surface is covered by land. Almost 70% of the Earth's surface is covered by land.
