2 Which heats and cools faster?

3 What is soil or land?

4 Draw graphs to show what water heated and cooled for 10 minutes would look like and what land heated and cooled for 10 minutes would look like.

5 Soil heats and cools quickly
Soil heats and cools quickly. Water heats more slowly but retains its heat longer than the soil. Time in minutes ˚F Soil Water

6 Give a definition and example of heat transfer by conduction.

7 What is heat transfer by direct contact of 2 objects that are different temperatures.
Ex. 1: When a person walks barefoot on the beach on a hot summer day. Ex. 2: Your little brother touches the frying pan on the stove. (ouch!)

8 Give a definition and example of heat transfer by convection.

9 Land and sea breezes, westerlies
Convection: What is heat transfer through liquid or gas where the warm part rises and the cool part sinks. Ex. Convection: Lava lamp Land and sea breezes, westerlies The water in the pot of water on the stove boiling. .

10 Give an example and definition of heat transfer by radiation.

11 Radiation: What is heat transfer through space which heats up the land/object without touching.
Examples of Radiation: Feeling really hot sitting next to a campfire Sun’s energy

12 Define Jet Stream.

13 What is a long narrow current of very strong winds in the upper atmosphere that affects the weather in the US (moves our weather west to east)?

14 Identify and describe what is happening in this picture.

15 What is a land breeze? The ocean is warmer than the land which causes the air above the ocean to rise and the air above the land to sink and replace the rising warm air. This forms a convection current (wind) from the land to water. (happens at night)

16 What causes weather systems to travel from west to east across the United States?

17 What are the westerlies and jet stream.
Follow up question: how does this knowledge help meteorologists?

18 It is the main cause of surface ocean currents?

19 What is wind

20 Ocean currents affect the weather around the world this way?

21 Warm ocean currents, such as the Gulf Stream can bring warmer temperatures to cooler areas while cool ocean currents can bring colder temperatures to the locations the current is near.

22 Give the name and location of the layer of the Earth’s atmosphere where most weather occurs.

23 What is the troposphere.

24 What is air pressure?

25 The weight of the air above pushing down.

26 Describe the weather result during a low pressure system.

27 What is cloudy skies and possible precipitation (rain, snow, etc.)?

28 Describe both temperature and movement of air over hot and cold surfaces.

29 What is a cold surface What is a hot surface Air move up
Air moves down

30 Look at the weather map. Use the symbols on the map to Describe the weather at locations 1, 2, and 3. (21) 1 3 2

31 Day 1: Clear skies Day 2: Clouds with rain / stormy Day 3: Clouds with rain / stormy

32 What do we call the movement of water through the environment?

33 What is the water cycle?

34 The process by which water changes from a liquid to an invisible gas called water vapor.

35 What is evaporation?

36 When warm water vapor rises and releases heat, what process occurs to form clouds?

37 What is condensation?

38 If the wind is blowing in the direction of arrow A OR B, what type of air would be carried to New Jersey? (2 answers) A B

39 A: What is a cold, dry air mass? B: What is a warm, moist air mass?

40 Which two air masses would contain polar, chilly air?

41 What is the dark blue (continental polar) and light blue (maritime polar) air masses?

42 A disturbance in the earth’s atmosphere that involves lightning, thunder, and sometimes gusty surface winds with heavy rain and hail.

43 What is a thunderstorm?

44 Describe a hurricane and how and where it forms.

45 What is a massive rotating storm that forms from rising warm air over warm, tropical waters.

46 In what ways are a hurricane and tornado alike?

47 What is they both contain winds that spiral very rapidly?

48 Describe what causes a tornado to form.

49 What is when air masses of very different temperature and humidity conditions meet. (happen over land & form from thunderstorms)

50 Most tornadoes occur here because cold, dry air from Canada collides with warm, moist air from the Gulf of Mexico head on.

51 What is tornado alley in central US.
