GEOG 1113L Lab 1: Essentials of Geography Exam 2025 Questions and
Answers 100% PASS |GSU
1. Which of the following best describes the shape of the Earth?
A. Perfect Sphere
B. Oblate Spheroid
C. Flat Plane
D. Prolate Spheroid
Answer: B
Rationale: The Earth is an oblate spheroid, meaning it is slightly flattened at the poles and
bulging at the equator due to its rotation.
2. Lines of latitude are also known as:
A. Meridians
B. Isotherms
C. Contour lines
D. Parallels
Answer: D
Rationale: Latitude lines are called parallels because they run parallel to the Equator and
never intersect.
3. What is the latitude of the Equator?
A. 180 degrees
B. 90 degrees
C. 0 degrees
D. 23.5 degrees
Answer: C
,Rationale: The Equator is the starting point for measuring latitude and is designated as 0
degrees.
4. Which line serves as the starting point for measuring longitude?
A. The Prime Meridian
B. The International Date Line
C. The Equator
D. The Tropic of Cancer
Answer: A
Rationale: The Prime Meridian, passing through Greenwich, England, is the 0 degree
reference for longitude.
5. What is the maximum value a line of longitude can have?
A. 90 degrees
B. 180 degrees
C. 360 degrees
D. 45 degrees
Answer: B
Rationale: Longitude is measured up to 180 degrees East or West of the Prime Meridian.
6. A Great Circle is defined as:
A. The Arctic Circle
B. Any line of latitude
C. Any circle that divides the Earth into two equal halves
D. A circle that does not pass through the Earth’s center
Answer: C
Rationale: A Great Circle is the largest possible circle that can be drawn on a sphere,
bisecting it into two hemispheres.
, 7. Which of the following is an example of a Great Circle?
A. The Tropic of Cancer
B. The Arctic Circle
C. The 45th Parallel North
D. The Equator
Answer: D
Rationale: The Equator is the only line of latitude that is a Great Circle; all other parallels
are Small Circles.
8. How many degrees does the Earth rotate per hour?
A. 10 degrees
B. 20 degrees
C. 15 degrees
D. 30 degrees
Answer: C
Rationale: Since the Earth rotates 360 degrees in 24 hours, dividing 360 by 24 results in
15 degrees per hour.
9. If it is 12:00 PM (noon) at 0 degrees longitude, what time is it at 30 degrees
East?
A. 10:00 AM
B. 4:00 PM
C. 12:00 AM
D. 2:00 PM
Answer: D
Rationale: Moving East adds time. 30 degrees divided by 15 degrees per hour equals 2
hours. So, 12:00 PM + 2 hours = 2:00 PM.
