Question

19 the earth changes seasons throughout its orbit, due to its
a rotation
b precession
c tilted axis
d distance from the sun

20 in the diagram, what season is it in the northern hemisphere? (line b represents the equator, night & day are illustrated)

a spring
b winter
c fall
d summer

1. at which of the following positions would north carolina be experiencing the winter solstice?

a a
b b
c c
d d

1. why does our moon go through phases?

a because we have night and day
b because the moon rotates on an axis
c because the moon orbits the earth
d because of the earths shadow

Explanation:

1. The Earth's seasons are caused by its tilted axis as it orbits the Sun. This tilt causes different parts of the Earth to receive varying amounts of sunlight at different times of the year.
2. In the diagram, the Northern Hemisphere is tilted away from the Sun, indicating it is winter. When a hemisphere is tilted away from the Sun, it receives less direct sunlight and has colder temperatures.
3. The winter solstice in the Northern Hemisphere occurs when the North Pole is tilted furthest away from the Sun. In the provided diagram, this would be Position A.
4. The moon goes through phases because it orbits the Earth. As it orbits, the amount of the moon's illuminated side that we can see from Earth changes.

Answer:

1. C. tilted axis
2. B. winter
3. A. A
4. C. because the moon orbits the Earth
