Earth

Welcome to **//__our__//** planet page!

Everybody who visits this page should know that we live on earth. If not, go to the library and get a book about **//__our__//** planet! We live about 93,000,000 Miles from the Sun. Earth takes 365 days to circle the sun. Scientists think that Earth probably formed at about the same time as the rest of the solar system. They have determined that some chondrite meteorites, the unaltered remains from the formation of the solar system, are up to 4.6 billion years old. Most of the time, Earth has been largely ice free. Brief ice ages occurred about 450 million years ago and again about 250 million years ago. In the last few million years, however, Earth's climate began to cool. Glaciers began forming in Antarctica about 35 million years ago, but the climate there was warm enough for trees to grow until about 5 million years ago. By about 2 million years ago, at the beginning of a time called the Pleistocene Epoch, ice had accumulated on other continents as well. Visit Mars
