a). Rotation
b). Revolution
c). Inclination
d). Axis shift
Answer: b). Revolution
Explanation: The Earth’s yearly movement around the Sun is called revolution, which causes changes in seasons.

a). 2 years
b). 3 years
c). 4 years
d). 5 years
Answer: c). 4 years
Explanation: After 4 years, the extra 6 hours each year add up to 24 hours, making one additional day in February (leap year).
Q. The imaginary plane formed by the Earth’s orbit around the Sun is called:
a). Axis plane
b). Orbital plane
c). Equatorial plane
d). Rotational plane
Answer: b). Orbital plane
Explanation: The orbital plane is the flat imaginary surface on which the Earth moves while revolving around the Sun.
Q. At what angle is the Earth’s axis tilted to the orbital plane?
a). 0°
b). 23½°
c). 45°
d). 66½°
Answer: b). 23½°
Explanation: The Earth’s axis is tilted at an angle of 23½° to the orbital plane, which causes the change of seasons.
Q. The circle that divides the day and night on the globe is called:
a). Equator
b). Tropic
c). Circle of Illumination
d). Axis line
Answer: c). Circle of Illumination
Explanation: As the Earth rotates on its axis, the circle of illumination shifts, creating day and night.
Q. The Earth moves around the Sun in which type of orbit?
a). Circular orbit
b). Elliptical orbit
c). Spiral orbit
d). Rectangular orbit
Answer: b). Elliptical orbit
Explanation: The Earth revolves around the Sun in an elliptical orbit, which is oval-shaped, not perfectly circular.
