prezi on water cycle
Transcript of prezi on water cycle
Time to start your review. You should have the following items handy:
handout that goes with this review
diagram of the water cycle
pen or pencil
Catastrophic Events manual
When you are ready, ensure you click on "More" and convert to "full screen." Then, click on the right arrow to advance the presentation.
Water continuously cycles through the different systems of Earth. Do you remember the Earth's systems? Answer all parts of the question below. This would be a great essay question...don't you think?
How does water continuously cycle through the:
biosphere? At one time or another, all of the water molecules on earth have been in an ocean, a river, a plant, an animal, a cloud, a raindrop, a snowflake, or a glacier! The water you drink today might have filled the wading pool of a Tyrannosaurus rex!! http://www.arizonaskiesmeteorites.com/Dinosaur_Fossils_For_Sale/T_rex_fossils_Tyrannosaurus_rex/Tyrannosaurus_rex.jpg On Earth, you can find water in all three states of matter. Solid as ice. Liquid as liquid water. Gas as water vapor. The phase of water is determined by its temperature and pressure. Let's take a moment and answer some questions about the states of matter, in general, and the states of water, specifically. How many states of matter are there?
What are the characteristics of a solid?
What are the characteristics of a liquid?
How is a gas different from a solid?
Why is solid water (ice) unique? http://wps.prenhall.com/wps/media/objects/165/169061/GIFS/AACQJAL0.JPG http://www.ucar.edu/learn/1_1_2_4t.htm There are many processes that are part of the water cycle. Remember, as you go through this prezi, circle or highlight the main points from the presentation in your study guide. If your study guide is incomplete, add the main points as you watch the review. Take several moments to look at the following cartoon. Good Work!
You've now reviewed the Water Cycle. To find out if you answered all of the questions in this review correctly, check out the associated video and see what your favorite science teacher has to say!
The video is only one more right arrow click away! What's the definition of temperature? How does pressure affect the state of water? A process is "a series of actions, changes, or functions bringing about a result."
For example, the process of evaporation changes liquid water into water vapor. The water vapor then rises with the warm air. Look at the following diagram and list (on your review handout) all of the processes you see. Then write their definitions. What process of the water cycle is missing from the diagram? It is represented by a cloud, but the "word" is not there.
You can hit the left arrow to go back to take another look at the diagram. As we finish this review, let's summarize and also make a connection between the water cycle and weather/climate. Water, which covers more than 70% of the earth's surface, circulates through the geosphere (crust), hydrosphere (oceans), and atmosphere (air) in what we call the "water cycle." The cycling of water in and out of the atmosphere plays an important role in determining weather and climatic patterns.
Water evaporates from the surface of the earth, rises and cools as it moves to higher elevations, condenses into rain or snow, and falls back again to the surface. The water falling on land collects in rivers and lakes, soil, and porous layers of rock underground. Most of the water flows back into the ocean."
