## Environment ### Natural environment * land, water, air, plants and animals comprise the natural environment * **Lithosphere:** Solid crust, the hard upper layer of Earth, made of rocks and minerals, covered by a layer of soil. Contains mountains, plateaus, plains, valleys, etc. Provides forests, grasslands for grazing and land for agriculture and human settlements. * **Hydrosphere:** Refers to different types of water sources (rivers, lakes, seas, oceans, etc.). Essential for all living organisms. * **Atmosphere:** Thin layer of air that surrounds the Earth. The gravitational force of the Earth holds the atmosphere around it. It protects us. **Let’s do** * Look at your surroundings and make a list of uses that your neighborhood is being put to. * Where does the water you use in your home and school come from? * Make a list of different uses of water in our daily life. Have you seen anyone wasting water? How? * Observe the sky while coming to school. Make a note whether the day is cloudy, rainy, sunny, foggy, etc.
