Passage 1: Millions of years ago the Earth looked much different than it looks today. All seven continents (North America, South America, Asia, Africa, Europe, Australia and Antarctica) were one gigantic continent Which scientists call Pangaea. The name Pangaea is derived from the Ancient Greek words “pan” meaning “entire,” and “Gaia” meaning “Earth.” Continental drift, the process by which the continents broke apart and spread out acroos the Earth, is caused by plates in the Earth’s crust that move around. Plate movement is what causes earthquakes and volcanic eruptions today. Continental drift didn’t happen all at once. It took millions of years. The first separation of Pangaea occurred when North America separated from Africa. The Atlantic Ocean was formed at this time. Next, south America, India, Antarctica and Australia broke apart. Because of continental drift, these continents are still moving a little bit each year. Some scientists even speculate that a new “super-continent” like Pangaea may form again! Try to imagine what the Earth will look like millions of years from now. Will it look the same as today, or will it look different? How does the author organiz the information in this passage?
