Unit 8 Whiteboard Review

• Weather and Climate

2
Weather

• What area of the Earth receives direct sunlight?
• The equator
• What area of the Earth receives indirect
  sunlight?
• The poles (north and south)
• The uneven heating of the Earths surface
  causes__________.
• Convection currents

3
Weather

• Due to convection, what does the warm air from
  the equator do?
• Rises towards the poles
• Why does the warm air rise?
• The warm air is less dense
• What does the cold denser air from the poles do?
• Sinks towards the equator and fills the space.

4
Weather

• What type of pressure system causes dry
  conditions and fair skies?
• High Pressure
• What pressure system causes stormy weather and
  clouds?
• Low Pressure
• What is air pressure?
• The amount of pressure on a surface from the
  atmosphere above it.

5
Weather

• What causes winds or breezes?
• Uneven heating of the Earths surface
• What type of air masses form over land?
• Continental (polar, arctic, tropical and
  equatorial)
• What type of air masses form over water?
• Maritime (polar, arctic, tropical and equatorial)

6
Weather

• What is the coldest air mass?
• Continental and maritime arctic
• What is the warmest air masses?
• Continental and maritime equatorial
• Which air masses affect Texas the most directly?
• Continental Tropic and Maritime tropic

7
Weather

• Which air mass is dry and the coldest?
• Continental Arctic
• Which air mass is moist and the warm, but not as
  warm as the equator?
• Maritime Tropical
• Which air mass is dry and cold (but not the
  coldest)?
• Continental Polar

8
Weather

• Why do air masses travel from polar regions to
  the equator?
• Their densitywarm air rises up towards the poles
  and cold air sinks down and fills those spaces.
• What tool do we use to measure air pressure?
• Barometer
• What unit does a barometer measure in?
• Millibars (mb)

9
Air Masses

• Which air mass is 1?
• Continental Arctic
• Which air mass is 2?
• Maritime Polar
• Which air mass is 3?
• Continental Polar
• Which air mass is 4?
• Maritime Tropical

• Continental
• What types of air masses are MOIST?
• Maritime
• What is the boundary between two air
• masses called that brings changes in
• weather?
• Fronts

11
Weather- Fronts

• What type of front brings warm and humid weather?
• Warm Front
• Draw the symbol for a warm front.
• What type of front brings rain and storms and
  leaves the area with cooler temperatures?
• Cold Front
• Draw the symbol for a cold front.

12
Weather- Fronts

• What type of front causes cloudy weather with
  chance of precipitation?
• Stationary Front
• Draw the symbol for a stationary front.
• What type of front leads to many days of clouds
  and precipitation?
• Occluded Front
• Draw the symbol for a occluded front.

13

• What type of front is by Miami?
• Stationary Front
• What type of weather will Miami have now?
• What type of air pressure is by Kansas?
• High Pressure
• What type of weather around Kansas?
• Clear skies, and mild weather

14
Winds

• Does wind always move in the same direction?
• No
• Name two things that affect wind direction and
  cause different wind belts.
• Convection currents and Coriolis Effect
• What type of ocean current is created and caused
  by wind?
• Surface currents

15
Winds

• Draw the wind direction in each wind belt.
• Start with the Easterlies and work down towards
  the trade winds at the equator.

16
Answer
17
Winds

• How does the Coriolis Effect change wind
  directions?
• It causes the curved paths of winds patterns in
  the different wind belts
• What is a jet stream?
• Narrow air currents found in the atmosphere of
  the Earth.

18
Ocean Currents

• What type of currents are caused by convection,
  and make up 90 of currents?
• Deep water currents
• What has a higher specific heat, water or land?
• Water
• What is the name of the surface current that
  travels along the eastern part of the US and
  brings stable, temperate weather to Europe?
• Gulf Stream

19
El Nino

• Does El Niño occur every year?
• No, every 2 to 7 years
• During El Nino, what can happen to the trade
  winds?
• Stop blowing, change direction or blow less
• What does El Niño do to the ocean temperature in
  the Pacific Ocean?
• Causes it to get warmer, increases the temp.

20
Hurricanes

• What conditions cause hurricanes to form?
• Low pressure and warm ocean water
• What would happen if hurricanes travelled over
  cold ocean water?
• They would weaken
• What types of damage do hurricanes cause on land?
• Storm surges, flooding, tornadoes, and strong
  winds

21
Hurricanes

• What is the weather like in the eye of the
  storm?
• Calm no strong winds or precipitation
• What area of the globe are hurricanes most likely
  to form in?
• The tropics, close to the equator
