Plants need their space too! If a plant grows too close to other plants, it may not grow healthy and strong, because the plants may compete over the available water, nutrients, and space in the soil for their roots to grow. Read more...iWorksheets: 5Study Guides: 1Vocabulary Sets: 2 Life Cycles of Plants and AnimalsA life cycle describes the stages an animal or plant goes through from birth to death. Some vertebrates change their appearance a lot during their life cycle while others hardly change at all. Most plants begin as a seed. A seed is a tiny plant, an embryo, in a little package. A seed stays inactive and doesn’t start growing until the conditions surrounding it are just right for it to start growing.

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 :4Study Guides :1Vocabulary :3 Earth - Inside and OutLet's look at the Earth from the inside out...
