Properties of Water
How much freshwater is on Earth?
3%
Describe the energy change. To begin, you have a ice cold glass of ice water. There is condensation on the outside of the glass. You leave it sit throughout the day and the ice is gone and the condensation is also gone.
Cold glass of water and ice absorbed energy, ice melted, condensation absorbed energy and evaportated.
Snow, hail, rain
precipitation
Area of higher ground that separates watersheds
Divide
A body of underground water that is stored in the pores between rocks and sediment is called...
Aquifer
Draw a water molecule, label the atoms and charges of them.
Two hydrogens (negative) and one oxygen (positive).
To create condensation, what type of energy transfer is needed?
Loss of energy or energy is released
Gas to a liquid
condensation
You have a stream that flows near your house. That stream flows into the Fox River. That stream can be classified as a ...
tributary
What would happen to your water supply if the discharge rate is greater than the recharge rate?
Water supply would run out
Water beading up and forming droplets is what water property?
Cohesion
To have sublimate ice, what is the energy transfer?
Ice absorbs energy
How do trees and plants fit into the water cycle?
Transpiration, plants give off water vapor
Surface water will erode soil. What prevents erosion, the best, in a watershed?
Plant life
Type of rock layer provides the best long term storage of water.
High porosity and high permeability
High porosity and low permeability
Low porosity and high permeability
Low porosity and low permeability
High porosity and high permeability
What property is responsible for weather (absorbing and releasing energy)?
Specific Heat
Describe the energy transfer as water falls from the sky to the surface.
It’s a physical transfer of energy from falling to erosive power. (potential to kinetic)
Water soaking into the ground
infiltration
What can increase the flow of a river?
Precipitation, snow melt, the size of the watershed...
Define water table
The area that allows water to soak into the ground and add water to an aquifer.
A challenge for developing countries
To have access to clean fresh water for health and for growing crops.
Warm ocean currents cool as they flow along a coastline, away from the equator. What is transported and how?
The ocean transports heat, it warms up the atmosphere around it while itself it cools down.
Two things water can transport
Energy and matter
Calculate the gradient of a river that starts at an elevation of 2200 ft and ends at 1600 ft. The river is 200 miles long.
3 ft / mi
The area that allows water to soak into the ground and add water to an aquifer.
Recharge zone
