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 angle the sun's rays hit a given surface on Earth.
polar
actually it's tropical not polar
38 degrees north
90° North and South ... the north and south poles.
Somewhere between 90 degrees (straight up) on the equinoxes, to 66.3 degrees at the solstices.
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 Summer Solstice (June 21).
This region receives the most nearly perpendicular insolation.
The Moon's equator; on average, the Sun will be at a higher angle there.The Moon's equator; on average, the Sun will be at a higher angle there.The Moon's equator; on average, the Sun will be at a higher angle there.The Moon's equator; on average, the Sun will be at a higher angle there.
The angle from the equator north or south to any point on Earthis the 'latitude' of that point.
Directly on the equator.
you can measure the angle of insolation by measuring the angle of the shadows that appear
the 30 degree angle is near the equator and the 90 degree angle is near the trop of Capricorn and cancer
Insolation is the amount of the Sun's energy reaching a unit surface area on Earth (for example energy per square metre). Insolation is reduced with increasing latitude, because of the angle at which the Sun's rays hit the surface. The changing angle at which the energy hits the surface means that the energy is spread over a larger area with increasing latitude, North or South. That's the main reason the poles are cold and the equator is hot. In the hemisphere where it's summer, the effect is not so extreme because of the Earth's axial tilt ("towards" the Sun, in that hemisphere). In the winter time at high latitudes the effect is very significant because the Earth is then "tilted away" from the Sun, in that hemisphere.
The angle of insolation into a surface is largest when the surface directly faces the Sun. That coincides with the temperature rising. So the angle of insolation goes up as the temperature goes up.

The temperature goes up because when the angle of insolation increases, it means that the sun's rays are becoming more directly focused on that area. That makes it hotter.For example, the equator is very hot. That's because that's where the sun's rays focus on most directly.The day is warm, and the night is cold.Summer is hot all day long if the angle of the sun is direct.YEARS:Summer = DirectWinter = IndirectFall/Spring = Half
This region receives the most nearly perpendicular insolation.
The angle the sun's rays hit a given surface on Earth.And the angle is measured from the horizon up to the position of the sun
higher at the equator and lower at the poles.
