Geography
Part 1: Location
Exercise 3.1:
- On the World map located at the end of this lab, plot the following coordinates with a dot. Label each dot with the corresponding letter:
Point A- 20˚ N, 60˚ E
Point B- 60˚ S, 90˚ E
Point D- 20˚ S, 120˚ W
Point E- 30˚ N, 90˚ W
- On the World map located at the end of this lab, draw and label the following important lines of latitude and longitude:
North Pole (90˚ N)
Arctic Circle (66.5˚ N)
Tropic of Cancer (23.5˚ N)
Equator (0˚)
Tropic of Capricorn (23.5˚ S)
Antarctic Circle (66.5˚ S)
South Pole (90˚ S)
Prime Meridian (0˚)
- If you began a trip at 60° east, 20° south and traveled 120° farther east and 60° north, your new position would be
- A) the International Dateline at 80° south latitude.
- B) the International Dateline at 40° north latitude.
- C) the Greenwich meridian at 80° south latitude.
- D) the Greenwich meridian at 40° north latitude.
Exercise 3.2:
Open the Lab 2 Digital Map: and answer the following questions. To determine the latitude/longitude coordinates of a place, use the Location tool found under Measure.

- Use the search bar to look up these locations. Remember that by convention, latitude is always listed first, longitude second.
| LOCATION | LATITUDE & LONGITUDE |
| New York City | |
| Buenos Aires, Argentina | |
| Brussels, Belgium | |
| Jakarta, Indonesia |
- Based on your answers to Question 1, complete the following sentences.
Locations in the northern hemisphere have a _____________ (positive or negative) coordinate, while locations in the southern hemisphere have a ______________(positive or negative) Locations in the Eastern hemisphere have a_______________ (positive or negative) coordinate, while locations in the Western hemisphere have a _______________ (positive or negative) coordinate.
- Use the search bar to answer these questions. Note: when using the search tool, you must enter longitude first and latitude second. There is no need to include the degree sign (°), but you must use the correct positive or negative signs (See Question 2). You may need to zoom out a bit once you enter the coordinates.
For example, to find Orange, Ca enter these coordinates: -117.85, 33.79
| LOCATION | TYPE | LATITUDE | LONGITUDE |
| major city | 31.19˚ N | 29.92˚ E | |
| major city | 12.05˚ S | 77.02˚ W | |
| country | 30˚ S | 25˚ E | |
| major city | 61.22˚ N | 150.05˚ W |
- Find your current location by using the compass on your phone or by dropping a pin on your phone’s map app. How does your location compare to the following location: 33.8121° N, 117.9190° W? Are you close by this location? How far away are you in terms of latitude/longitude? Are you north or south of this location? East or west? Be as specific as possible when describing your current location in relation to this location.
Exercise 3.3:
- Convert the following locations in Degrees, Minutes, and Seconds to Decimal Degrees. Show Work.
| LATITUDE | LONGITUDE | ||
| Degrees, Minutes, Seconds | Decimal Degrees | Degrees, Minutes, Seconds | Decimal Degrees |
| 35° 40’ 60” N | 139° 39’ 58” E | ||
| 30° 2’ 20” S | 25° 28’ 30” E | ||
- Convert the following locations in Decimal Degrees to Degrees, Minutes, and Seconds. Show Work.
| LATITUDE | LONGITUDE | ||
| Degrees, Minutes, Seconds | Decimal Degrees | Degrees, Minutes, Seconds | Decimal Degrees |
| 12.0433° S | 77.0283° W | ||
| 59.8581° N | 17.6447° E | ||
- You are considering your next vacation. One possibility is Location A at 17.6626° N and the other is Location B at 17.7589° N. Assuming that 1° of latitude is approximately 69 miles on Earth’s surface, Location A is how many miles closer to the equator than Location B?
Part 2: Time– “Sun” time versus ”Clock” time
Exercise 3.4:
- Within the Pacific Standard Time Zone, Los Angeles (based on 118˚ W) reports sunrise at 6:20 A.M., what time will the sun rise in San Bernardino (based on 117˚ W)?
- Within the Pacific Standard Time Zone, Victorville (based on 117˚ W) reports sunset at 6:36 p.m., what time will the sunset in Santa Barbara (based on 120˚ W)?
- On July 25, Dover, Delaware experienced sunrise at 5:56 am. Elsewhere in the Eastern Standard Time Zone, City A (at a similar latitude) experienced sunrise at 6:36 am.
- Is City A west or east of Dover? Explain your reasoning.
- How many degrees of longitude separate these two locations?
Part 3: Time– Standard Time
Exercise 3.5:
Use the longitude of the time zone’s controlling meridian (which has been provided for you) to answer the following questions.
- If it is 7:00 P.M. in Houston (based on 90˚ W), what time is it in New York City (based on 75˚ W)?
- If it is 8:00 A.M. Thursday in Denver, Colorado (based on 105˚ W), what time and day is it in Beijing, China (based on 120˚ E)?
- At Location A (based on 120˚ W), it is 1:00 P.M. Tuesday, elsewhere at Location B it is 11 P.M. on Tuesday.
What is the longitude of Location B?
- Your plane leaves Seattle, Washington (based on 120˚ W) at 10:00 P.M. on Friday, bound for Orlando, Florida (based on 75˚ W). The flight takes 6 hours. What is the time and day when you arrive in Orlando? Hint: Calculate difference in time then add flight time.
- Your plane leaves Los Angeles (based on 120˚ W) at 11 P.M. on Monday bound for Sydney, Australia (based on 150˚ E). The flight takes 13 hours. What is the time and day when you arrive in Sydney? Hint: Calculate difference in time then add flight time.
- On your return flight from Sydney, you leave at 3 P.M. on Sunday. The flight takes 14 hours. What time and day is it when you arrive in Los Angeles? Hint: Calculate difference in time then add flight time.
