Ever since the earth formed, about 4 billion years ago.
because that is how long the earth takes to make 1 full rotation on its axis
•Mars and earth both have 4 seasons but a year on Mars is about twice as long as it is on Earth, so the 4 seasons would amount to about 8 seasons on earth. • The temperatures on mars can be as low as -124.6 degrees Fahrenheit • Earth's atmosphere is mostly nitrogen and oxygen, where as Mars's atmosphere is made out of 95% Carbon-dioxide
earthworms were the third form of life. They have been around for over 2000 years.
Earth Day is to celebrate Earth since it's been here for who-knows-how-long. This is when you get outside and play, or even clean around your house or something. Keeping the Earth clean means clean water, clean oxygen, and clean houses even. So when Earth Day comes around, get off your bottom and go outside! Earth Day is celebrated on April 22nd.
You do not say what will harm the earth. The earth is a dynamic planet, if it did not have the processes which cause earthquakes and volcanoes it would be a dead planet. While earth stays dynamic, constantly active, it is the perfect place for us.
Since man has walked the earth.
Mercury's storms can last for several Earth-days to weeks. These storms are driven by the intense heating and cooling cycles on the planet due to its lack of atmosphere.
There are no hurricanes on Mars. Mars has a thin atmosphere that is unable to generate the large and powerful storms seen on Earth.
how long has archaebacteria been on earth? how long has archaebacteria been on earth?
That is impossible to determine. Hurricanes have been going on since long before there were people around to record them, and even then there are many historical accounts of storms that may or may not have been hurricanes.
Well, electricity isn't living, and it's been around for ages. Lightning and thunderstorms contain electricity. Sand storms can create static electricity. So it's been around about as long as the Earth.
How Long Has This Been Going On was created in 1996-01.
Not in any state. Dust storms have been occurring on earth since long before people were around to create states or nations and before the continents had taken on their present forms. Furthermore, dust storms are not limited to the United States.
Yes, Jupiter does have storms, most notably the Great Red Spot, a massive anticyclonic storm that has been raging for at least 400 years. Jupiter's atmosphere is constantly in motion, with high-speed winds and turbulent weather patterns creating numerous storms across the planet. These storms are fueled by the planet's rapid rotation and its immense size, which generate strong atmospheric dynamics.
they have been on the earth for along time
They didn't. It was just the first tornado to be recorded by people that was in 1054. Prior to that any tornadoes that were witnessed were likely just mentioned as fearsome storms. There is no doubt that they were going on long before people walked the earth. Tornadoes have likely been occurring since the Precambrian time.
no, storms systems on earth only last a few weeks at most. The energy involved is a lot less, the atmosphere a lot less dense (than Jupiter) and the terrain beneath the storm will vary. The storms on earth lose their energy when they travel over land.
