Meteors 1. Meteoroids are small pieces of rock or metal floating in outer space. 2. When meteroids float near to the earth, they may be drown into the Earth's atmosphere due to gravity. 3.Meteroids which enter the Earth's atmosphere are called meteors. 4. Most meteors will burn up when they enter the Earth's atmosphere due to friction. 5. Thus, streaks of light can be seen in the sky at night in the dark. They leave behind fiery tails and are called shooting stars. 6. Meteors which do not burn completely and reach the Earth's surface are called meteorites. 7. Meteorites which fall to the ground will make huge craters. One crater is found in Arizona, the United States of America. 8. Many planets and their natural satellites are covered with meteorites craters. However the Earth does not many meteorite craters since it is protected by its atmosphere. ARIZONA CRATER
