CheckPoint: Study of Earth The Lithosphere consists of Earth’s outermost layer. This is the land we live on, mountains, hills, volcanoes that every few decades or centuries have a tendency to erupt lava that covers the immediate area. Once it cools down, new life has a way of being created. The land we live one provides us with food that we plant, easy access of getting from one place to another by walking or driving, and to build homes in which to live. The Biosphere is the genetic makeup of all living and recently deceased plant, animal, bacteria and human life. The biosphere deals with all life on land and water. The biosphere is part of the atmosphere which helps in sustaining life on earth. The atmosphere is a mass of gases that surrounds the earth. It consists of the air we breathe and exhale. Plants and trees produce oxygen for us to breathe while the air (carbon dioxide) we exhale is used by the plants and trees to produce photosynthesis along with the sun to keep them alive. The Earth's atmosphere is divided into five main layers; the Exosphere, Thermosphere, Mesosphere, Stratosphere, Troposphere. Each of these layers is mainly determined by whether temperature increases or decreases with altitude. The Hydrosphere holds the Earth’s bodies of water and ice on the planet and underground caves and caverns. Within this hydrosphere you have the process of precipitation. This process happens when the sun’s rays hit bodies of water and evaporates it. The particles that are evaporated travel through the atmosphere and get trapped in the clouds. Once the clouds can no longer hold the precipitation, we have rain which falls to the back to the ground. Water also plays a part in the erosion and fertilization of the land.
