Unit 5: Hydrosphere – Draw/Create a pie chart

Unit 5: Hydrosphere:

1) Draw/Create a pie chart to show what percentage of Earth is saltwater and what percentage of Earth is fresh water.

? Where is MOST of the freshwater on Earth found?

? Draw/create a diagram of the water cycle and include the following things labeled: precipitation, condensation, transpiration, evaporation, run-off, accumulation, percolation, groundwater, water table, aquifer, spring, well.

2) Draw and label something that is permeable and something that is impermeable.

? Why is permeable rock necessary for an aquifer to form?

3) Make a vocabulary table for the following properties of water: cohesion, adhesion, polarity, buoyancy, universal solvent, salinity. (Example of how to create the table below.) Word Definition Picture or Example

4) Create a Venn Diagram for point source pollution and nonpoint source pollution.

?Give at least 2 facts/examples of each type of water pollution on each side of the Venn Diagram.

5) Draw/create the 5 life zones in the ocean and include:

? Paste pictures from online of examples of life forms found in each zone.

? Based on what they are, how do upwelling and downwelling affect ocean life in these zones?

6) Copy the following sentences into your slides and fill in the blanks:

? An _______________ is when salt water from the ocean mixes with __________________ from a

river.

? The 3 main gasses found dissolved in the ocean are _________, _________ & ________.

? Sunlight only penetrates so far through the water, so some organisms use the process of

_____________________ rather than photosynthesis to make energy.

7) What 3 things happen the deeper you go into the ocean?

? How do we use technology to overcome these challenges?

? What have we gained by using technology to explore the ocean?

8) Explain the process of eutrophication – what causes it, what happens during the process & what is the outcome?

9) Match the following water quality indicators with the correct definition AND copy the indicators and their

definitions into your book:

_____ 1. Temperature      a. The amount of dissolved oxygen in the water

_____ 2. Turbidity              b. An element that can be found in the water that is toxic to humans when they eat contaminated fish

_____ 3. Bio-indicators      c. Tells you how acidic the water is

_____ 4. pH                         d. If the water is too hot or too cold, it will harm or kill the living things in the water

_____ 5. Nutrients             e. This indicator is usually good but if there is too much in the water it can become toxic

_____ 6. Dissolved Oxygen    f. The measure of how cloudy the water is due to stuff in it

_____ 7. Mercury                   g. These are specific animals that live in the water that can indicate if the water is healthy or not

_____ 8. Coliform bacteria   h. Indicates the presence of fecal matter (poop)

10) How is turbidity related to temperature and dissolved oxygen?

Extra Credit: Describe the steps our wastewater goes through to be cleaned.

? The agency that is in charge of protecting our water, establishing water treatment standards and ensuring the quality of our drinking water is the _________________________________________________________. An amendment written by this agency in the 1970’s called the ____________________________________ specifically helps protect surface waters by making point source pollution illegal. Doing our part to take care of Earth is known as ________________________.
