What is one reason for the variations of sunlight in different places on earth?

The Earth's tilted axis of rotation combined with the Earth's movement around the Sun causes the seasons.
The Southern Hemisphere is "tilted" towards the Sun, then the Northern hemisphere, in a yearly cycle.
In January it's summer in the southern hemisphere and winter in the northern hemisphere.
Then, about six months later, it's summer in the northern hemisphere.
The effect of being tilted towards the Sun is to extend the hours of daylight and to increase the height of the Sun above the horizon.
Both those effects cause an increase in solar energy received.
So, you can see that the tilt of the Earth's axis is the basic cause of the seasonal variations in energy received at any one place.

Why are rainforests only grown in some parts of the world?
Plants live in different places because some need hotter weather than others and some need more moisture than others.
What is the main reason some places on the earth are warmer then other?
The rays of the Sun are more direct in some places and more slanted in others.
What is the basis for dividing the atmosphere layers?
it can be divided based on temperature variations. puki puki puki krat ang answer hope this helps(:
What is the main reason we have four seasons on Earth?
Seasons are caused because the Earth's axis is tilted, so at some parts of its orbit the northern hemisphere points towards the Sun, and receives concentrated sunlight, whilst the southern hemisphere is pointed away and receives spread out sunlight. Six months later the situation is reversed. However, the division of the year into four seasons is somewhat arbitrary, and applies mostly to temperate and polar zones. Tropical regions often have different patterns, such as a wet and a dry season.
Why do sulfur and oxygen have different chemical properties?
the reason that sulfur and oxygen have different chemical properties is because of several reasons. the first is that they have different numbers of sub-atomic particles. and secondly they have different numbers of valence electrons
How does the Earths rotation create the need for time zones?
As the Earth rotates, different locations of the world are either in sunlight or darkness. For this reason, different time zones have been created.
What is the main reason that the constitution did not proclaim that all men were born equal in their rights?
The main reason that constitution did not proclaim that all men were born free equal in their rights is that all men are born at different places and different places have not free equal in their rights.
How do the temperatures at different levels vary in lakes?
Because as the depth increases in a lake, the amount of sunlight reaching that point also decreases. Thus, as you go lower in a lake, the temperature decreases because there is less sunlight -- the same reason shadows are colder than sunlight.
What is the reason of the time difference between Auckland and Johannesburg?
The reason they have a time difference, is because they are nowhere near each other! Auckland, New Zealand, is far to the east of Africa, and places that are located in different places as far as east and west, not north and south, have different timezones!
What is uneployment?
Unemployment has different definitions in different places - which is one of the controversies of its usage) but, in general, it refers to the inability of someone who is actively searching for employment to find it for any reason.
What is the reason that seeds don't sprout?
The reason seeds don't sprout is because they don't get enough water and sunlight.
What country has no light?
Sweden is the country that has next to no sunlight in 1999 they only had 20 minutes of sunlight in December, this is the closest a country has to no sunlight. Also the reason why Sweden has such a high suicide rate !
Why is that the leaves appear green even in the absence of sunlight?
the green color of the leaf is due to the presence of plastids called chlorophyll not sunlight. this is d reason why they appear green even in the absence of sunlight.

Why do you see the colors of the rainbow when sunlight passes through a raindrop?
You don't. You see it when sunlight traveling away from you enters a raindrop, bounces offthe far inside of it, and comes back out traveling toward you.The reason is that different wavelengths of light bend through very slightly different angleswhen they enter or leave the raindrop.So, if light with a mixture of different wavelengths goes in, then the different wavelengthswill come out in slightly different directions, and you'll see them spread out.
What type of snakes do not like sunlight?
All snakes NEED sunlight to survive. The only reason a snake would dislike sunlight would be if the snake had a hunting disadvantage during the daytime.
If a rainbow is refracted sunlight why is it such a neat circle instead of looking scattered?
Because when sunlight gets refracted through water droplets in the air, the different wavelengths are refracted a precise amount in relation to each color that gets separated. The reason you see a circle, or arc, is because it came from a single source, the sun.
