Water Cycle
Where does water go when it evaporates from a puddle in the street?
it rises into the atmosphere
About 97% of all the water on Earth is in the form of ______________.
salt water
Water interacts with rock formations. Which of the following can happen?
1. climate changes 2. canyon forms 3. sediment forms 4. rain fall 5. high tide occurs
2. a canyon forms
3. sediment forms
Why is it important to conserve freshwater?
Because only a small fraction of Earth's water is freshwater, and everyone needs it.
By definition, a storm surge can occur when a ______________ causes large waves in the ocean.
hurricane
All water on Earth is recycled through _________.
the water cycle
True or false: Oceans are a source of fresh water.
false
Define sediment.
Dirt, rock, sand that gets broken down from rocks and living things.
What is a reservoir?
A place where fresh water is collected and stored.
The hydrosphere can affect the geosphere in positive and negative ways.
True or False
True
All of Earth's liquid and solid water make up the __________.
hydrosphere
Why is it important for humans to conserve freshwater?
Only a small fraction of Earth's water is freshwater, and everyone needs it.
Sediment that is weathered and broken down gets moved by a process called _________________.
erosion
How is building a dam one way to store water?
Creating a barrier across a river helps cause water to back up and form a reservoir, and then can be used for drinking or watering plants, etc. when you need it.
How can water cause a landslide?
Heavy rain can cause the movement of rocks, dirt down a slope.
____________ rain can be caused by burning fuels that mix with water in the clouds.
acid
Where is most of Earth's fresh water found?
Most of Earth's freshwater is trapped in glaciers and ice caps.
deposition
List two ways to conserve water:
1. turn off water when brushing teeth
2. limit shower time
3. clean up pollution
4. collect water in shower or rain water outside to water plants
(do you have your own way?)
Glaciers can cause changes in the geosphere in a fast or slow manner?
slow
How does evaporation lead to precipitation.
This is a 3 point answer that will need to be written out on the test.
Evaporation is water that has risen as a vapor into the atmosphere. As it rises, it condenses into clouds. When the clouds get too heavy and full, the water is pulled down back to Earth by gravity in the form of precipitation.
Why does the biosphere need groundwater?
All living things need water to survive. Ground water contains the most freshwater that is available to us and provides about 50% of the Earth's drinking water.
The shape of different landforms is often changed by
_______________ water.
a. flowing
b. standing
flowing
_________________ water can harm living things.
a. polluted
b. clean
Here is the breakdown of freshwater on Earth:
0.76% groundwater/freshwater
1.74% ice caps/glaciers
0.1% lakes/rivers/soil/air
Add the percents together to tell someone the exact percent of freshwater on the Earth.
2.6% of the Earth's water is freshwater
