1. Essential Question: Where is the Earth’s water located?
Element:
S6E3a. Obtain, evaluate, and communicate information to recognize the significant role of water in Earth processes. a. Ask questions to determine where water is located on Earth’s surface (oceans, rivers, lakes, swamps, groundwater, aquifers, and ice) and communicate the relative proportion of water at each location.

"Water, Water, Everywhere...." You've heard the phrase, and for water, it really is true.
Earth's water is (almost) everywhere: above the Earth in the air and clouds, on the Earth as rivers, oceans, ice, inside the Earth in the top few miles of the ground. Water is even in living things.
Instructional Approach(s): The teacher should present the information on the slide.

4. Use the Organizer to record your findings
Use the Organizer to record your findings! (Some answers are in red and underlined others you have to read carefully)
Instructional Approach(s): The teacher should give each student a copy of the Location of Water on Earth Notes [linked on the resource page] to record important information during the lesson.

Groundwater occurs as a liquid resource that is dispersed through numerous holes, pores, fractures and cavities in bodies of rock or sediment

10. Where is Earth's water located and in what forms does it exist
Where is Earth's water located and in what forms does it exist? You can see how water is distributed by viewing these bar charts. The left-side bar shows where the water on Earth exists; about 97 percent of all water is in the oceans. The middle bar shows the distribution of that three percent of all Earth's water that is freshwater. The majority, about 69 percent, is locked up in glaciers and icecaps, mainly in

11. Greenland and Antarctica
Greenland and Antarctica. You might be surprised that of the remaining freshwater, almost all of it is below your feet, as ground water. No matter where on Earth you are standing, chances are that, at some depth, the ground below you is saturated with water. Of all the freshwater on Earth, only about 0.3 percent is contained in rivers and lakes— are where most of the water we use in our everyday lives exists.

12. The top pie chart shows that over 99 percent of all water (oceans, seas, ice, most saline water, and atmospheric water) is not available for our uses. And even of the remaining fraction of one percent (the small brown slice in the top pie chart), much of that is out of reach. Considering that most of the water we use in everyday life comes from rivers (the small dark blue slice in the bottom pie chart), you'll see we generally only make use of a tiny portion of the available water supplies. The bottom pie shows that the vast majority of the fresh water available for our uses is stored in the ground (the large grey slice in the second pie chart).

13. What is saline? Read Only for question 1
First, what do we mean by "saline water?" Water that is saline contains significant amounts (referred to as "concentrations") of dissolved salts, the most common being the salt we all know so well—sodium chloride (NaCl). In this case, the concentration is the amount (by weight) of salt in water, as expressed in "parts per million" (ppm). If water has a concentration of 10,000 ppm of dissolved salts, then one percent (10,000 divided by 1,000,000) of the weight of the water comes from dissolved salts. Here are our parameters for saline water: Fresh water - Less than 1,000 ppm Slightly saline water - From 1,000 ppm to 3,000 ppm Moderately saline water - From 3,000 ppm to 10,000 ppm Highly saline water - From 10,000 ppm to 35,000 ppm By the way, ocean water contains about 35,000 ppm of salt

14. Look at the data table below.

15. The blue spheres represent the relative amounts of Earth's water in comparison to the size of the Earth.
Are you surprised that these water spheres look so small? They are only small in relation to the size of the Earth.
Overall, it shows that in comparison to the volume of the globe the amount of water on the planet is very small.

Instructional Approach(s): The teacher should present the information on the slide.

16. The largest sphere represents all of Earth's water.
The sphere includes all the water in the oceans, ice caps, lakes, and rivers, as well as groundwater, atmospheric water, and even the water in you, your dog, and your tomato plant.

Instructional Approach(s): The teacher should present the information on the slide.

17. How much of the total water is fresh water, which people and many other life forms need to survive?
The blue sphere over Kentucky represents the world's liquid fresh water (groundwater, lakes, swamp water, and rivers).
Instructional Approach(s): The teacher should present the information on the slide.

18. Do you see the "tiny" bubble over Atlanta, Georgia?
That one represents fresh water in all the lakes and rivers on the planet.
Most of the water people and life on earth need every day comes from these surface-water sources.
Instructional Approach(s): The teacher should present the information on the slide.

Water on the Earth
About 71% of the earth’s surface is covered with water.
Of the total volume of water on Earth:
97% is saltwater
In general, most of the earth’s water is located in the oceans as saltwater . So where does it come from?
Instructional Approach(s): The teacher should present the information on the slide while the students record the important information on their notes.

20. By some estimates, if the salt in the ocean could be removed and spread evenly over the Earth's land surface it would form a layer more than 500 feet (166 meters) thick, about the height of a 40-story office building (NOAA).
Instructional Approach(s): The teacher should present the information on the slide.

21. Water on the Earth 2% is freshwater frozen in ice caps and glaciers
1% is fresh water in lakes and streams, groundwater, and water vapor in the atmosphere
In general, most of the earth’s water is located in the oceans as saltwater . Most of the freshwater on Earth is located in glaciers and ice caps. Lesser amounts are found in atmospheric moisture, rivers, lakes, streams, and groundwater.
Most of the freshwater on Earth is located in glaciers and ice caps.
Instructional Approach(s): The teacher should present the information on the slide while the students record the important information on their notes.

22. Water on the Earth
Water is not evenly distributed, and most of it is unsuitable for drinking.
We use less than 1% 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.
Unless we use our freshwater supply wisely, rivers, lakes and groundwater can be depleted or polluted, becoming unusable or unsuitable for life.

26. Problem on Back: The Estuary—where fresh and saltwater mix.

27. Estuary, partly enclosed coastal body of water in which river water is mixed with seawater. In a general sense, the estuarine environment is defined by salinity boundaries rather than by geographic boundaries. The term estuary is derived from the Latin words aestus (“the tide”) and aestuo (“boil”), indicating the effect generated when tidal flow and river flow meet.
