Water Cycle
1) Name the process in the water cycle happening at #1 in the diagram.
What is Evaporation?
5) Layer of the atmosphere where weather and the water cycle occur.
______________
What is the Troposphere?
11) How is altitude related to air pressure??
Air pressure decreases as altitude increases. ✅
Here’s why:
Air pressure is caused by the weight of the air above you.
At higher altitudes, there is less air above, so the weight pushing down is lower.
This is why mountain climbers and pilots experience lower air pressure the higher they go.
In short: higher altitude → lower air pressure; lower altitude → higher air pressure.
16) Which layer of the atmosphere is the mesosphere? ____________
What is the Third Layer?
22) How is the atmosphere important to us?
The atmosphere is important to us because it:
Provides oxygen for breathing and carbon dioxide for plants.
Protects us from harmful solar radiation with the ozone layer.
Regulates Earth’s temperature by trapping heat (the greenhouse effect).
Allows for weather and the water cycle, which are essential for life.
Protects Earth from meteoroids, most of which burn up in the atmosphere before reaching the surface.
In short: The atmosphere sustains life and shields Earth from dangers in space.
Name of the process in the water cycle happening at #3 in the diagram
What is Condensation?
7) Layer of the atmosphere where you would find the ozone layer. _____________
What is the Stratosphere?
12. Define transpiration?
What is the process by which plants release water vapor into the air through tiny openings in their leaves called stomata
17) ________ enters the troposphere through a process called evaporation.
What is Water?
the emission or transmission of energy in the form of waves or particles through space
Radiation
4) The temperature gets _________ as you move up through the troposphere.
Pick an option and highlight. (higher, warmer, younger ,colder)
What is Colder?
8) __________ is a gas (form of oxygen) that is found only in the stratosphere.
What is the Ozone Layer?
13) Water vapor turning into liquid is called __________
What is condensation?
18) What layer of the atmosphere do humans live in? ___________
What is the Troposphere?
movement in a gas or liquid in which the warmer parts move up and the colder parts move down
What is Convection?
3) Name of the process in the water cycle happening at #5 in the diagram
What is the run off?
9) Water falling from clouds in any form, such as snow, ice, raindrops, or drizzle
_________________________.
What is Precipitation?
14) Which layer of the atmosphere is the thermosphere?
What is the 4th layer✅
19) What layer of the atmosphere is the ozone in? ___________
What is the Stratosphere?
When heat transfers from objects that are touching.
What is Conduction?
6) ________ form as a result of a process called condensation.
What are Clouds?
10) A type of run-off that occurs when the surface is not porous or precipitation is falling too fast for the water to seep into the ground. Pick an option and highlight. (surface water flow, groundwater flow, precipitation).
What is Surface water flow?
15) The mesosphere has ___________ air pressure than the troposphere.
What is Lower?
20) Water cycle is driven by the ___________.
