What is climate?

• I can describe weather factors.

#1

• Where does sunlight strike earth most directly?

• Equator

2

• Why is it colder closer to the poles?

The Sun’s rays strike at less direct angle and the heat spreads out.

3

• On what part of the Earth is sunlight least concentrated?

• poles

4

• How does the amount of heat energy from the Sun at the equator compare with the amount of heat energy from the Sun at the Poles? BE SPECIFIC in your answer

• The amount of heat energy from the Sun is the same at the equator as the poles. It is the angle that is different.

5

• Why do scientists describe the Earth as made up in layers?

• Different layers have different characteristics. Different layers have different amounts of gas particles.

6

• What is air pressure?

• The force put on a given area by the weight of the air above it.

7

• Describe insolation and its affect on the atmosphere.

•

8

• Does all the energy from the sun stay on earth? Give an example in your answer

• Only about 50% is absorbed by Earth’s surface

9

• What happens to molecules as the temperature rises.

• As the temperature rises the molecules move faster and faster and farther apart

10

• What are global winds? Where do global winds come from?

• Are winds that blow steadily over long distances in a predictable direction,

• Sunlight heats the equator more than Earth’s poles,

11

• What are local winds?

• Causes– Different parts of Earth’s surface are heated by

the Sun at different rates.

12

• How are local winds different than global winds?

• Global winds are worldwide• Local winds are in a specific area

13

• How do we measure air pressure and wind? Instruments

• Barometer– measures atmospheric pressure • Anemometer—measures wind speed• Weather vane—instrument that shows which

way the wind is blowing.

14

• Make a chart showing the 3 main types of clouds, give a visual description of each type, describe the weather associated with each type of cloud.

15

• List the 4 types of precipitation.

• Rain, snow, sleet, hail

16

• Compare and contrast air masses and front?

• An air mass is a large region of air that has a similar temperature and humidity

• An front---where one air mass meets another, this meeting place

17

• What happens when a cold air mass meets a warm air mass?

• A storm---

• Three main types of fronts (cold, stationary and warm)

18

• Describe highs and lows

• Highs– is a large mass of air with the highest air pressure (warmer, humid air)

• Lows– a large air mass with low air pressure • Isobar--

19

• Describe thunderstorms, winter storms, tornadoes, hurricanes

How do they form? What are some of the results of these storms? How can these storms be tracked?

20

• How are these storms #19 tracked?

• Doppler radar and # 13

21

• What is climate? (Use the concept web given in class for the next questions)

• The average weather of a place. 2 important variables are temperature and rainfall

22

• What factors affect climate? (use the concept map)

• • How does climate affect you? List 3 ways. (Use

the concept map)

24

• What affects climate?

25

• What affects does El Nino have on climate?

26

• What is the name used for a scientist that studies climate?

• Climatologist

27

• What is the name used for a scientist that study the weather?

• Meterologist.
