Question

1. what is the main reason earth has seasons? 2 points a. earths distance from the sun changes b. earths tilt on its axis as it orbits the sun c. the moons gravitational pull d. changes in earths orbit speed 2. when the northern hemisphere is tilted toward the sun, what season is 2 points it there? a. winter b. summer c. fall d. spring

Explanation:

For question 1: Earth's tilt on its axis as it orbits the Sun causes different parts of the Earth to receive varying amounts of solar radiation throughout the year, leading to seasons. The distance from the Sun (A) changes slightly but is not the main cause. The Moon's gravitational pull (C) affects tides, not seasons. Changes in orbit speed (D) are related to Kepler's laws but not the main reason for seasons.
For question 2: When the Northern Hemisphere is tilted toward the Sun, it receives more direct sunlight, resulting in summer. Winter (A) occurs when tilted away. Fall (C) and Spring (D) are transitional seasons.

Answer:

1. B. Earth’s tilt on its axis as it orbits the Sun
2. B. Summer
