What is the source of energy for the water cycle?
The sun.
Examples of energy transfer in the water cycle include…
+When water melts from its surroundings as water melts from solid to liquid.
+Energy is transferred from water into its surroundings when water condenses from gas to liquid
What is the water cycle?
The water cycle is the movement of water in the Earth system.
Name the states of water.
Gases, liquids, and solids
What are the different states of water?
Evaporation, Transpiration, Sublimation, Condensation, and Precipitation.
What is the Coriolis effect?
The Coriolis effect is the deflection of moving objects from a straight path due to Earth’s rotation.
What drives deep currents?
The differences in water density.
What drives surface currents?
The sun causes winds to form, and winds cause surface currents to form.
What is a convection current?
Any movement on of matter that results from differences in density; may be vertical, circular, or cyclical
In Evaporation water….
evaporates
In Transpiration water…
releases water vapor in the air by plants
In Sublimation water…
solid water changes directly to liquid water
In Condensation water…
changes from liquid to gas
In Precipitation water…
Falls to Earth
The properties of water are…
Cohesion, adhesion, surface tension, and capillary action
What processes contribute to adding water vapor into the atmosphere?
Evaporation, Transpiration, and, and Sublimation
What is the atmosphere?
The mixture of gases that surrounds Earth
What are the layers of the atmosphere?
Troposphere, Stratosphere, Ozone layer, Mesosphere, and Thermosphere
Where is the Ozone layer located?
Stratosphere
How thick is the troposphere?
10-12km thick
What does the troposphere provide?
Oxygen + where most weather takes place
How high is the stratosphere?
50km above Earth;’s surface (15-40 km area)
What does the Ozone layer do?
Absorbs large amounts of ultraviolet radiation from the sun
How many km above is the Thermosphere?
80km
