The angle of insolation is different at different locations on Earth because the Earth is split into 3 main regions: Polar, Temperate, and Equator. Since Earth is a sphere, the middle is more more direct to the sun, unlike the other regions. So, the sun would "give" the heat to the equator more easily and the heat spreading on the other regoins would spread and it takes some time to heat them up.
This all has to do with something called the flux. This is a measure of how much energy from the sun hits a square meter per second. What causes some parts to get more radiation is a difference in the flux. The poles are at high altitude and so the flux is very low being that the angle of the incoming radiation is really high.
Answer #1:
Because the Earth revolves around the Sun, so the seasons change.
That's because the Earth's axis is tilted relative to the Earth's orbit.
So, as the Earth orbits the Sun it is tilted towards the Sun in summer and then away from the Sun in the winter.
Hence, the angle at which sunlight hits Earth (at any particular place) changes during the year.
The summers (and winters) occur 6 months apart in the northern and southern hemispheres.
===========================
Answer #2:
The angle at which sunlight hits the Earth doesn't change. At every moment
in time, the sun's radiation arrives at the Earth's surface at angles anywhere
between zero and 90 degrees, depending on the specific surface location.
The angle is constantly changing at any fixed location because the Earth is
rotating. And it doesn't repeat at that location at the same time on successive
days because the Earth's axis of rotation is not perpendicular to the direction
toward the sun.
When either the southern or northern hemisphere is tilted towards our star, the Sun, more of the Sun's radiation hits each square meter of the surface, in that hemisphere.
Also, the number of hours of sunlight per day increases.
This results in higher temperatures at the latitudes getting more sunlight.
the orbit on which the earth revolves around the sun is not round but elliptical .so when the earth reaches near to the sun in compared to other times while revolving in the elliptical path ,the sunlight received is more.
besides,when the earth rotates,the equator receives the most of the sunlight but the polar regions receive a little less
Over the course of a year ... yes, pretty much. In the summer, the days are longer, and in the winter the nights are longer; it averages out.
There might be a very small discrepancy due to the fact that a year is not exactly an even number of days, but over the longer term, even this averages out.
Because the earth rotates on a axis witch causes our day and nights. We rotate in a circle and tilt witch causes our seasons also. But if something like a tree is blocking the light it causes shade.
yes they do as the tilting of the earth makes little difference to them
Yes. The sun hits the earth at different angles. Different latitudes get different amounts of direct sunlight at different times.
Because of the tilt in the earth's axis and the rotation of the earth around the sun
Stars range in many different shapes and sizes some have super energy and others have less energy. Usually the more mass the star has the more light it will seem to emit more light, the distance can matter, one thing to remember when looking at the stars is that it can and does take thousands of years for the light from a star to reach the Earth. Some stars are brighter than others because they have more energy than others.
It is 168 light years from the Earth. See the related link for more information.
Yes! The Earth reflects more than half on the sun's light.
Like the moon, all the planets get their apparent brightness by reflecting light towards us from the Sun. At some stages Mars is reflecting more light towards Earth, so it appears to be brighter. Also, sometimes it is closer than at other times, so it appears to reflect more light towards us.
The rotation of the earth is not at a perfect angle, so some places get more heat than othersand some places don't even get heat.
The rays of the Sun are more direct in some places and more slanted in others.
It depends on the way the Earth is tilted
The tilt of Earth's axis gives more light to the areas experiencing "summer". The sunlight that reaches the Earth also depends on the average cloud cover.
places are closer to the eqater and dont get as much rain:)
Some places have more constant winds than others.
Because some parts of earth are farther from the sun and some are closer.
Some places are built close to fault lines. Fault lines are 'cracks' in the Earth's crust that move against each other - creating earthquakes and volcanos.

Some places have a more Germanic heritage than others.
Mass and density. The more mass an object has the higher its gravitational pull is. Some places on Earth are more dense than others. therefore they have more mass which can slightly increase the gravitational pull at that area.
yes
There are not more stars, it is simply that more can be seen. And that is because rural places suffer from light pollution.
