Part 1: Location

Exercise 3.1:

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

 

 

1. 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˚)

1. If you began a trip at 60° east, 20° south and traveled 120° farther east and 60° north, your new position would be
2. A) the International Dateline at 80° south latitude.
3. B) the International Dateline at 40° north latitude.
4. C) the Greenwich meridian at 80° south latitude.
5. 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.

 

You may also access this map from Canvas.

1. 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

 

 

 

1. 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.

 

1. 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

1. 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:

 

1. 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

 

 

 

 

 

 

 

 

 

 

1. 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

1. 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:

1. 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)?

 

1. 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)?

 

 

 

1. 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.
2. Is City A west or east of Dover? Explain your reasoning.
3. 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.  I have also included a blank diagram to help you visualize time zones.

1. 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)?
2. 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)?

 

1. 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?

1. 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.

 

 

 

 

 

 

1. 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.

 

1. 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.
