During an equinox, the sun's rays are most direct at the Earth's equator. This is because during an equinox, the tilt of the Earth's axis is such that the sun is directly over the equator, leading to equal day and night lengths at all latitudes.
At noon on the vernal equinox, the sun's vertical rays strike the earth along the equator. This is when the lengths of day and night are nearly equal all over the world.
On the equinoxes, the sun's direct rays fall on the equator. This causes day and night to be of equal length all over the world.
There is no time between these. On the day before the autumnal equinox, the sun is directly overhead in the northern hemisphere (at a latitude just north of the equator). The following day, it is directly overhead in the southern hemisphere (just south of the equator). The sun goes from being overhead in the northern hemisphere to the southern hemisphere instantaneously, the change happening at the autumnal equinox.
The Vernal Equinox marks the beginning of spring in the Northern Hemisphere and occurs around March 20th each year. It is the point in Earth's orbit when the tilt of the Earth's axis is perpendicular to the Sun's rays, resulting in approximately equal lengths of day and night.
During an equinox, the sun's rays are most direct at the Earth's equator. This is because during an equinox, the tilt of the Earth's axis is such that the sun is directly over the equator, leading to equal day and night lengths at all latitudes.
Equinox
The Sun is never ON the equator, it is above the equator twice a year - the spring equinox and the fall equinox.
During the vernal equinox, the sun's most direct rays travel approximately 0.5 degrees of latitude per day. This is because the sun moves across the celestial sphere at a rate of about 1 degree per day, and since the Earth is tilted at about 23.5 degrees, the direct rays shift between the Tropic of Cancer and the Tropic of Capricorn throughout the year. On the equinoxes, the sun is directly overhead at the equator, marking the transition of direct sunlight between the two tropics.
December 21 or 22.
At noon on the vernal equinox, the sun's vertical rays strike the earth along the equator. This is when the lengths of day and night are nearly equal all over the world.
This event is known as the equinox. During the equinox, the Earth's axis is not tilted towards or away from the Sun, resulting in nearly equal amounts of daylight and darkness across the planet. It marks the official start of spring in the Northern Hemisphere and autumn in the Southern Hemisphere.
Yes, direct rays heat a place more than indirect rays. Direct rays are concentrated and deliver more energy per unit area compared to indirect rays, which are more dispersed and have lower energy intensity. This is why direct exposure to sunlight can feel much warmer than being in the shade on a sunny day.
On the equinoxes, the sun's direct rays fall on the equator. This causes day and night to be of equal length all over the world.
The word is "equinoctial" = equal day and night. It occurs twice a year, on the first day of Spring, and the first day of Autumn.
December 21 or 22, coinciding with the Winter Solstice in the northern hemisphere.
On September 23rd, the sun's rays are directly over the equator, marking the beginning of autumn in the Northern Hemisphere and spring in the Southern Hemisphere. This day is known as the autumnal equinox in the Northern Hemisphere.
