Question

select all the correct answers.

which of the following are valid names for the equinoxes?

fall equinox
partial equinox
total equinox
spring equinox

Explanation:

Analyze the equinox concept

Using the Earth-Moon-Sun System and Orbital Relationships knowledge points, we analyze the Earth's orbit and axial tilt. An equinox occurs twice a year when the plane of Earth's equator passes through the geometric center of the Sun's disk, resulting in nearly equal day and night.

Identify valid names

The two equinoxes are named after the seasons in which they occur:

• The equinox in March is known as the spring equinox (or vernal equinox) in the Northern Hemisphere.
• The equinox in September is known as the fall equinox (or autumnal equinox) in the Northern Hemisphere.

Terms like "partial equinox" and "total equinox" do not exist in astronomy (these terms are associated with eclipses).

Answer:

• fall equinox (Correct answer)
• partial equinox
• total equinox
• spring equinox (Correct answer)
