What happens in the Southern Hemisphere during the equinox?
An equinox is an event in which a planet’s subsolar point passes through its Equator. The equinoxes are the only time when both the Northern and Southern Hemispheres experience roughly equal amounts of daytime and nighttime.
What equinox is the Southern Hemisphere in?
In the Southern Hemisphere the equinox occurs on March 20 or 21, when the Sun moves north across the celestial equator.
How does the equinox affect the hemisphere?
The equinoxes are the only times when the solar terminator (the “edge” between night and day) is perpendicular to the equator. As a result, the northern and southern hemispheres are equally illuminated.
What happens in the Southern Hemisphere from December solstice to March equinox?
The December solstice marks the start of winter: at this point the South Pole is tilted closest to the Sun, and the Sun’s rays are directly overhead at the Tropic of Capricorn. (In the Southern Hemisphere the seasons are reversed.) The equinoxes happen in March (about March 21) and September (about September 23).
How does the equinox affect us?
What are equinoxes? What causes these astronomical events? Find out how they influence the seasons and hours of daylight on each planet. Every six months, once in March and again in September, an equinox splits Earth’s day almost in half, giving us about 12 hours of daylight and 12 of night.
What equinox are we in Australia?

What is an equinox which season are indicated by it in both the hemisphere?
equinox is an event in which a planet’s subsolar point passes through its Equator. The equinoxes are the only time when both the Northern and Southern Hemispheres experience roughly equal amounts of daytime and nighttime. On Earth, there are two equinoxes every year: one around March 21 and another around September 22.
Why is equinox important?
These two crossings are very important for the inhabitants of Earth, because they mark the change in the direction the sun’s rays fall on Earth. Specifically, on Sunday, the sun will move from the Northern Hemisphere to the Southern Hemisphere.
Why is the equinox important?
Why are seasons reversed in the Southern Hemisphere?
Regardless of the time of year, the northern and southern hemispheres always experience opposite seasons. This is because during summer or winter, one part of the planet is more directly exposed to the rays of the Sun than the other, and this exposure alternates as the Earth revolves in its orbit.
