Question

1. why does the northern hemisphere experience warmer temperatures during summer?

a. the earth is closer to the sun
b. the suns rays hit the surface more directly
c. the earth spins faster
d. there are fewer clouds in the atmosphere

1. what is an equinox?

a. the longest day of the year
b. when the earth is closest to the sun
c. when day and night are equal in length
d. the shortest day of the year

1. how long does it take the earth to complete one orbit around the sun?

a. 24 hours
b. 365.25 days
c. 28 days
d. 12 months exactly

1. which other planet experiences seasons for the same reason as earth?

a. venus
b. jupiter
c. mars
d. mercury

Explanation:

• For question 5: During summer in the Northern Hemisphere, the Earth's tilt causes the Sun's rays to hit more directly, leading to warmer temperatures. It's not about distance to the Sun, Earth's spin speed, or cloud - cover primarily.
• For question 6: An equinox occurs when the tilt of the Earth's axis is perpendicular to the Sun's rays, resulting in day and night being of equal length.
• For question 7: The Earth takes approximately 365.25 days to complete one orbit around the Sun. 24 hours is the time for one rotation, 28 days is related to the Moon's cycle, and 12 months is an approximation but not as accurate as 365.25 days.
• For question 8: Mars has seasons similar to Earth because it also has an axial tilt. Venus has a very small tilt and no distinct seasons like Earth, Jupiter is a gas giant with different atmospheric dynamics, and Mercury has a very small tilt and no significant seasonal changes like Earth.

Answer:

1. b. The Sun's rays hit the surface more directly
2. c. When day and night are equal in length
3. b. 365.25 days
4. c. Mars
