The test will cover the following: 1. What are the four properties of water? Be able to explain them.

2. Water Cycle: What is it and how does it work?

3. What is a hydroelectric power plant and how does it work?

4. How do hurricanes and tsunamis form?** (7th & 8th grade)

5. What is the difference between surface water and groundwater? What are some examples?

6. Explain the relationship between high and low permeability and porosity.

7. What is the relationship between an observation and an analysis in an experiment or study.

Question 1. Polarity. A water molecule is slightly charged on both ends. ...

Cohesion. Hydrogen bonds hold water molecules together, as seen in the picture above. ...

Adhesion. And

High Specific Heat. Question 2. The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation. ... The cycling of water in and out of the atmosphere is a significant aspect of the weather patterns on Earth.Question 3. Hydropower plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy. Question 4. Hurricanes often bring with them a storm surge, which is a broad dome of higher sea level, lifted up by the low pressure in the storm center. ... So, in summary, tsunamis are caused by earthquakes shifting the ocean floor, and hurricanes are big storms that form in the atmosphere over warm ocean waters Question 5 - . Water is generally classified into two groups: surface water and groundwater. In general: Groundwater is located underground in large aquifers and must be pumped out of the ground after drilling a deep well. Surface water is found in lakes, rivers and streams and is drawn into the public water supply by an intake. Question 6: If the material has high permeability than pore spaces are connected to one another allowing water to flow from one to another, however, if there is low permeability then the pore spaces are isolated and water is trapped within them. Question 7 : What's the difference between observational and experimental studies? ... a observational study is where nothing changes and just record what you see, but an experimental study is where you have a control group and a testable group.

Explanation:  I can only put so many words but try putting them intu your OWN words <3 it'll help sound more natural  in your essay or paper
