PART 1 – LATITUDE AND LONGITUDE:

Using the map above list the approximate latitude and longitude for each location. Latitude is always written first and longitude second. Number 1 and be completed for you as an example.

1) Location A: 20°S, 100°E

2) Location F: ____°___ , ____°___

3) Location G: ____°___ , ____°___

4) Location H: ____°___ , ____°___

5) Location J: ____°___ , ____°___

Find your latitude & longitude. There are two ways you can do this: If you have an iPhone, the first way is to use the compass app (there may be a comparable app for android but I don’t know). You will likely be asked to calibrate your compass by turning your iPhone. After calibrating, your latitude should be listed near the bottom of the screen below your compass direction. Write you latitude and longitude in the question 6 space below.

If you don’t have an iPhone or can’t get the app to work, you can go to this website: http://mygeoposition.com/ to find your latitude and longitude. Just type your address into the search bar near the top and click “calculate geodata”. Use the angular degrees not the decimal degrees. Write you latitude and longitude in the space below.

6) ____°___ ‘ _____’’ ___ , ____°___ ‘ _____’’ ___

PART 2 – TIME:

Use the map above to answer the questions below. A similar map also included in chapter 1 of the textbook.

7) It’s noon on Monday in New York City, what day/time is it in London, England?

8) It’s 3:00pm on Wednesday in Los Angeles, what day/time is it in Rio de Janeiro, Brazil?

9) It’s 2:00am on Sunday in Lagos, Nigeria, what day/time is it in Chicago?

10) It’s 2:00pm on Friday in the country of Peru (look it up if you have to), what day/time is it in Ohio? PART 3 – THE SEASONS:

Above is a diagram of the Earth’s revolution around the sun over the course of a year. A similar diagram is also included in chapter 2 of the textbook. Use the diagram to answer the questions below.

11) What date is it when the Earth is at position A?

What date is it when the Earth is at position B?

12) How many hours of daylight does the Equator see at position D?

13) Areas above the Arctic Circle see how many hours of daylight at position E?

14) Does the southern or northern hemisphere receive more hours of daylight at position F?

PART 4 – THE ATMOSPHERE:

Use the diagram above to answer the questions below. Similar diagrams(s) can also be found in chapter 2 of your textbook.

15) Which temperature layer of the atmosphere is higher in altitude, the Troposphere or the Stratosphere?

16) In what functional layer of the atmosphere is the Ozone layer found in?

17) Notice that the Equatorial tropopause creates the top of the Tropospere, the Stratopause creates the top of the Stratosphere, and the Mesopause creates the top of the Mesosphere. What happens to temperature at each of the “pauses”?

PART 5 – TEMPERATURE AND TEMPERATURE CONVERSIONS

Consult information in chapter 3 of the textbook to help you answer these questions:

18) The melting/freezing point of ice/water is: ____°F and ____ °C

19) Water boils at: ____°F and ____°C

20) What happens at 0° Kelvin (K)?

21) 0°K equals: _____ °F and _____°C

Use the following mathematical formulas to convert temperatures:

Celsius to Fahrenheit

(°C * 1.8) + 32 = °F

Fahrenheit to Celsius

(°F – 32) * 0.556 = °C

22) 20°C equals ____°F

95°F equals ____°C

PART 6 – ATMOSPHERIC PRESSURE AND CIRCULATION

B

A

The diagram above is a cross-section of a general atmospheric circulation model in the Northern Hemisphere. Use it to answer the questions below. Consult chapter 4 of the textbook.

23) What is the approximate latitude of point A? ____° ; Point B? ____°

24) Is low or high pressure found at point A? __________ ; Point B? __________

25) What is the circulation cell between point A and point B called?
