The Earth is a perfect sphere. True or False?
- True
- False
- It is a perfect sphere only at the equator
- It is a perfect sphere only at the poles
Show answer
Answer: B. False
The Earth is not a perfect sphere. It is an oblate spheroid, meaning it bulges at the equator and is flattened at the poles due to its rotation.
The Tropic of Cancer is located at approximately:
- 0 degrees latitude
- 23.5 degrees North latitude
- 23.5 degrees South latitude
- 66.5 degrees North latitude
Show answer
Answer: B. 23.5 degrees North latitude
The Tropic of Cancer is a circle of latitude that marks the northernmost point at which the Sun can be directly overhead. It is located at approximately 23.5 degrees North latitude.
What is the approximate angle of the Earth's axial tilt?
- 0 degrees
- 15.5 degrees
- 23.5 degrees
- 90 degrees
Show answer
Answer: C. 23.5 degrees
The Earth's axis is tilted at an angle of approximately 23.5 degrees relative to its orbital plane around the Sun. This tilt is the primary cause of seasons.
What is the time difference between the Prime Meridian (GMT) and a location 30 degrees East longitude?
- 2 hours ahead
- 2 hours behind
- 12 hours ahead
- 12 hours behind
Show answer
Answer: A. 2 hours ahead
Since each degree of longitude represents 4 minutes, 30 degrees of longitude represent 30 x 4 = 120 minutes, which is 2 hours. Locations east of the Prime Meridian are ahead in time.
The Earth's rotation causes a slight flattening at the poles and a bulge at the equator. This shape is called:
- Prolate spheroid
- Oblate spheroid
- Ellipsoid
- Geoid
Show answer
Answer: B. Oblate spheroid
The centrifugal force generated by Earth's rotation causes it to bulge at the equator and become flattened at the poles, resulting in an oblate spheroid shape.
