Final Exam Study Guide
1. How do thunderstorms form?
1. Warm moist air rises forcefully
2. Water vapor condenses providing energy for
the storm
3. Updrafts and downdrafts maintain storms
energy
4. Storm dissipates when it runs out of energy
2. Where do they form?
• Along cold fronts
3. How is lightning created?
• Electrical discharge between two oppositely
charged surfaces.
4. Where can lightning travel?
• From one part of the cloud to another part
• From one cloud to another cloud
• From cloud to ground
5. What is thunder?
• Rapidly expanding and contracting air from
the lightning bolt creates sound waves
6. What kinds of clouds produce
tornadoes?
• Cumulonimbus clouds
7. What is a supercell?
• Powerful thunderstorm that can produce
tornadoes
8. How do tornadoes form?
• Warm and cold air meet and rotates
horizontally
• Updrafts push column of air vertical
• Rotating air descends it picks up dirt and
debris
9. What is a hurricane? How do they
form?
• Massive tropical cyclone that forms over warm
waters, with extremely strong winds and rain
• Water vapor evaporating and then condensing
within the storm gives it energy
• As clusters of thunderstorms strengthen, they
begin to rotate
10. Where do each of these tropical
cyclone form?
• Cyclone
• Hurricane
• Typhoon
• Indian Ocean
• Atlantic Ocean
• Pacific Ocean
11. What is the rainband of hurricane?
• Region of heavy thunderstorms beyond the
eyewall that spiral outward from the center of
a hurricane
12. What is the Coriolis Effect?
• Spiraling of winds due to the Earth’s rotation
13. What is the eye of the hurricane?
And what is the pressure there (high
or low)?
• Circular region located at the center of a
hurricane
• Warm air is rising, creating a low pressure
zone
• Surrounded by the eyewall which is the most
destructive part of a hurricane.
14. What is global warming?
• A gradual increase in average global
temperature
• Due to:
– Burning of fossil fuels
– Extra heat in the atmosphere
– Greenhouse Effect trapping more heat than
normal
• Normally a natural process, but humans are
speeding it up, thus making it worse.
15. What are the two gases that make
up most of our atmosphere?
• Nitrogen
• Oxygen
16. What is wind?
• Movement of air from high to low pressure
17. What are the three phases of
matter? Describe each phase.
• Solid
– particles are barely moving
– Substances hold their own shape and do not flow
• Liquid
– particles are moving slowly
– Substances take on the shape of their container and
flow
• Gas
– Particles are moving quickly
– Substance fills the shape of it’s container and flows
18. What is the Fujita Scale?
• Measures the intensity of a tornado
• F0 – F5
19. Where is Tornado Alley located?
• American Midwest
– Great Plains
20. What can destroy/diminish a
hurricane?
•
•
•
•
Wind shear
Cold water
Land
Saharan Air Layer
21. What is a front?
• The boundary between air masses
22. Describe the weather at each of
these fronts:
• Cold front
• Warm front
• Stationary front
• Occluded front
• Severe thunderstorms
• Drizzly weather
• Many cloudy and rainy
days
• Cool temp. & a lot of
rain
23. Describe each layer of the
atmosphere:
• Troposphere
• Stratosphere
• Mesosphere
• Thermosphere
• All weather happens
here
• Ozone layer
• Meteor’s burn up
• Hottest but you would
feel cold / satellites fly
here
24. Describe each type of air mass:
•
•
•
•
Maritime polar
Maritime tropical
Continental polar
Continental tropical
•
•
•
•
Moist, cold
Moist, warm
Dry, cold
Dry, warm
25. What is the water cycle? What
powers it?
• Continuous movement of water within Earth’s
atmosphere, land, and oceans/lakes
• Sun
26. Create a flow map of the water
cycle.
Cloud / Condensation
Precipitation
Evaporation
Runoff
Infiltration /
Percolation
Ocean/Lake
27. What happens to water content as
warm rises? As it cools?
• Warm air rises and becomes cooler, it loses
the ability to hold water
• Cool air sinks and becomes warmer, it gains
the ability to hold water
28. What is the Greenhouse Effect?
• Greenhouse gases trap heat and keep the
Earth warm
29. What causes the seasons?
• Tilt of the Earth’s axis
30. Why type of star is the hottest
(blue or red)?
• blue
31. What could happen when a star
dies?
•
•
•
•
•
White Dwarf
Supernova
Neutron star
Pulsar
Black hole
32. How are craters formed on the
Moon?
