Question

1. what is the movement of an object in space spinning on its axis?

a. rotation
b. revolution
c. orbiting
d. parallelism

1. when the northern hemisphere experiences winter, the southern hemisphere is having

a. winter
b. summer
c. spring
d. an equinox

1. when it is spring in the northern hemisphere what season is it in the southern hemisphere?

a. spring
b. summer
c. autumn
d winter

Explanation:

• Question 15: Rotation is the movement of an object spinning on its axis. Revolution is the movement around another object. Orbiting is similar to revolution. Parallelism is not related to this type of motion.
• Question 16: Due to the tilt of the Earth's axis, when the Northern Hemisphere is tilted away from the Sun (winter), the Southern Hemisphere is tilted towards the Sun (summer).
• Question 17: Seasons in the Northern and Southern Hemispheres are opposite. So when it is spring (growing season, moderate temperatures as the hemisphere is transitioning) in the Northern Hemisphere, the Southern Hemisphere is in autumn (harvesting season, temperatures cooling as it moves away from summer).

Answer:

1. a. Rotation
2. b. summer
3. c. autumn
