Equinox
The Sun is never ON the equator, it is above the equator twice a year - the spring equinox and the fall equinox.
I would try going to NASA.com and looking up that answer
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.
When the sun's most direct rays hit the equator, typically during the equinoxes, day and night experience nearly equal lengths of time, approximately 12 hours each. This phenomenon occurs because the tilt of the Earth's axis is such that sunlight is distributed evenly across the equator. As a result, temperatures are generally consistent, and the equatorial regions experience a balanced climate with minimal seasonal variation. This equal distribution of light also influences ecosystems and habitats in these areas.
the solstice occurs when the sun is farthest north of the equator
Summer occurs south of the equator at the same time winter occurs north of the equator and vice versa.
it occurs in warm ocean areas near the equator
The sun is strongest at the equator because of its direct angle, resulting in more intense solar radiation. The most direct sunlight on Earth occurs in the tropics, where the sun's rays hit the Earth's surface more vertically compared to higher latitudes.
Near the equator, a tropical climate prevails with high temperatures and high humidity. This region typically experiences consistent warmth throughout the year and receives abundant rainfall. Tropical rainforests are common in equatorial areas.
Most of Earth's precipitation occurs in the tropics near the equator. This region experiences high levels of evaporation and warm air, which leads to the formation of clouds and ultimately precipitation.
This is called the "equinox", or "equal nights" - when the night and day are approximately the same duration.
