What is the primary reason for weather on the Earth?

Answer 1

The blanket of air that covers the earth is called

the atmosphere. The bottom layer of the atmosphere is

called the troposphere. The troposphere is where all of

earth’s weather happens. Basically, our weather is

caused by two things: the sun and moisture in the air.

These two things together can from clouds, make rain

and thunderstorms, and cause winds to blow. Without

the sun and moisture in the air, our earth would have no

weather at all. In fact, there would be no people or plants

either.

Another thing that helps to cause the earths

Weather is air masses. When two air masses come

Together, the line between them is called a front. Along a

Front there is usually clouds, rain, and maybe thunderstorms.

The movement of air masses helps to cause weather

almost as much as the sun and moisture in the air. Without

air masses, all the earth’s weather would say in one place.

Answer 2

The primary reason for the weather on Earth is to provide a common topic of conversation for everybody. It's too cold, too hot, too wet, not enough rain, too windy, etc. See, endless possibilities! And what would the storm chasers chase if we had no weather? And think about the unemployment issue, if we didn't need weather forecasters, the unemployment figures would be up at least another 2%! And don't forget the guys who make, sell and service snow blowers - more unemployment!
Most importantly, how would you pick a good day to skip work if we had no weather. It would defeat the purpose of ringing in "sick". So as you can see, there a a great number of reasons why we need weather on Earth.

Answer 3

This is an excellent question but I'm going to have to answer this question by saying I do not believe there is but one "primary reason" for the Earth's weather. There are at several important reasons. They are the Sun, the tilt of the Earth's axis, and the rotation of the Earth. But also of importance is the existance of the Earth's atmosphere without which there would be no weather. Of parallel importance with the atmosphere is the Earth's oceans without which there would be no clouds, or water vapor of consequence. These are in my opinion all of equal importance in creating and sustaining the Earth's weather machine.

Answer 4

Well the atmosphere allows weather to happen. Rain and snow and any precipitation are just the laws of conservation of mass. The mass of evaporated water has to go somewhere, it can't just disappear. And weather is just basically there to let the earth replace it's resource, rivers, water, humidness, etc.

Answer 5

Life

Answer 6

Your respondents who said the sun are correct.


If someone were to blot out the sun --- turn it off, so to speak--- in less than a week, everything would be frozen solid, and the temperature at the surface of the planet would be absolute zero.(google absolute zero.) (The center core of molten magma is not enough to keep the planet warm.)

Answer 7

The tilt of the earth's axis causes our weather.. If was not for this, we would be burnt to a crisp.

Answer 8

The sun, warming/cooling the surface of the Earth and souping it up.

Answer 9

The Sun.

Answer 10

The poles are cold, and the equator hot. That sets up pressure differences that need to be equalled out.
