The average duration of insolation at the equator is approximately 12 hours per day throughout the year. This consistency occurs because the equator receives nearly direct sunlight year-round, with minimal variation in day length between seasons. Consequently, the equatorial regions experience relatively stable temperatures and weather patterns due to this uniform solar exposure.
March has the greatest duration of insolation for the equator due to the vernal equinox, when the sun is directly overhead. This leads to more direct sunlight and longer daylight hours in March.
There is no 'why' because that statement is false. The equator is right in the CENTER of the tropics. As the sun wiggles back and forth between the edges of the tropics each year, the equator is the place that receives the MOST average insolation.
The angle of insolation affects the intensity of insolation directly. In other words, as the angle of insolation increases, so does the intensity of insolation because the Sun is directly overhead at Zenith, giving off direct, or vertical rays. The opposite happens when the angle of insolation decreases, causing a decrease in the intensity of insolation as well.
The equator receives its maximum average daily insolation during the equinoxes, which occur around March 20-21 and September 22-23 each year. During these times, the sun is directly overhead at the equator, resulting in nearly equal day and night lengths. Consequently, the equator experiences the highest levels of solar radiation during these periods.
On March 21, the Earth receives the greatest intensity of insolation at the equator, which is located at 0 degrees latitude. This date marks the vernal equinox, when the sun is directly overhead at the equator, resulting in nearly equal day and night lengths across the globe. As a result, the equator experiences the highest solar radiation intensity at this time.

The duration of insolation on March 21, also known as the spring equinox, is approximately 12 hours. This is because on the equinox, the sun is directly above the equator, resulting in nearly equal lengths of day and night worldwide.

Directly on the equator.
The duration of insolation is the same everywhere on the days of the equinoxes - around March 20-21 for the vernal (spring) equinox and around September 22-23 for the autumnal equinox. During these times, the sun is directly above the equator, resulting in approximately equal day and night lengths worldwide.
Insolation refers to the amount of solar radiation that reaches a given area. The duration of insolation varies throughout the day, with maximum exposure typically occurring around midday when the sun is highest in the sky. Factors such as time of year, latitude, and cloud cover can also affect the duration of insolation.
Duration of insolation
Earth's surface affects the duration of insolation by influencing the angle at which sunlight strikes it due to factors like latitude and topography. Regions near the equator receive more direct sunlight and experience longer durations of insolation, leading to warmer climates, while regions closer to the poles receive less direct sunlight and have shorter durations of insolation, resulting in colder climates. Additionally, features like mountains and clouds can also impact how much sunlight reaches the surface.

The opposite happens when the angle of insolation decreases, causing a decrease in the intensity of insolation as well.
The zone that has the highest insolation is the Tropics, located near the Equator. This region receives the most direct sunlight throughout the year due to the angle of the Earth's tilt.
The region with the highest insolation is the Sahara Desert in Africa. This area receives some of the most intense sunlight on Earth due to its location near the equator and lack of cloud cover.
An increase in duration of insolation will typically lead to an increase in soil temperature. The longer the soil is exposed to sunlight, the more heat it absorbs, resulting in higher temperatures. This can have various impacts on soil processes, such as affecting microbial activity, nutrient availability, and plant growth.
