Changes on earthA glacier is a slow moving large body of ice. A volcano is an opening in the Earth’s crust from which hot, melted rock forcefully comes out when pressure is built up inside the Earth. An earthquake is a sudden shift in the Earth’s crust that causes the ground to shake and vibrate violently. Weathering is the process of rocks being changed over time by conditions such as rain, snow, ice, pressure.Read more...iWorksheets: 5Study Guides: 1Vocabulary Sets: 3 Earth in spaceFreeThe Sun, which is a star, is Earth's source of heat and light.
