Today marks the start of spring in the Northern Hemisphere. What is the day called?
A Solstice
B Equinox
C Perihelion
The equinox is the point at which the sun sits directly over the Earth’s equator as it moves between the Southern and Northern Hemispheres, making day and night almost equal in length. From this point on in the Northern Hemisphere, the day will be longer than the night, until the autumn equinox.
The correct answer is Equinox.
