Why are summer days longer than winter days on Earth? A. During the summer, Earth's rotational axis is parallel to the Sun's rotational axis.
B. During the summer, Earth is at the point in its orbit when it is closest to the Sun.
C. The region of Earth experiencing summer rotates past the Sun more slowly than the region experiencing winter.
D. The region of Earth experiencing summer is tilted toward the Sun while the region experiencing winter is tilted away from the Sun.
PLEASE HELP ITS A TEST

A. During the summer, Earth's rotational axis is parallel to the Sun's rotational axis.

Explanation:

Actually, though, the Earth is tilted 23.4 degrees! (A circle is 360 degrees.) This tilt is the reason that days are longer in the summer and shorter in the winter. The hemisphere that's tilted closest to the Sun has the longest, brightest days because it gets more direct light from the Sun's rays.

Plz mark me brainliest if correct :)

c is the answer because when something is left after something evaporates that shows the chemical change.
