What’s In Scientists increasingly view Earth as a dynamic system – a combination of interrelated, interdependent or interacting parts forming a collective whole or entity. Earth system, in terms of its four central components known as the subsystems are the: hydrosphere (water), lithosphere (land), atmosphere (air) and biosphere (living thing). These subsystems are interconnected by processes and cycles, which, over time, intermittently store, transform and/or transfer matter and energy throughout the whole Earth system in ways that are governed by the laws of conservation of matter and energy. The energy that drives these processes comes mainly from the Sun and sometimes from energy sources within the Earth. COMPONENTS OR SUBSYTEMS OF THE EARTH SYSTEM 6 Hydrosphere (“hydro “means water) This covers about 75% of Earth’s surface, including groundwater and Earth’s frozen water (the cryosphere) and almost 1% of the water is drinkable. The Oceans help regulate climate by absorbing large amounts of solar energy, particularly near the equator, and circulating heat towards the poles. Water constantly circulates between the hydrosphere, the lithosphere, and the atmosphere through water cycle processes. Lithosphere (“litho” means stone or rock) Made up of plates and it includes all the solid part of the Earth that covers approximately 10% of earth’s surface and deeply affects every part of the ecosystem. It extends up to the inner core of the planet. Soil supports billions of plants, animals, and microorganisms, it filters water, and it facilitates the decomposition of wastes. This holds air, water, heat, and nutrients and is the medium in which we grow food and fiber. It is responsible for the formation of many landforms through its endogenic activities. Atmosphere (“atmos” means vapor) This component is the blanket of gas that surrounds Earth. This distributes rain and traps some of the heat radiated by Earth to help keep us warm. It also protects us from harmful solar radiation through the ozone layer, and plays a role in driving ocean currents that redistribute Earth’s heat. Component layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere. Biosphere (“bio” means life) It consists of all living things, plants and animals, from microbes to humans. This is intimately connected with and dependent on the other spheres. Through processes such as photosynthesis, respiration, decay, and human activity such as burning forests or fossil fuels, the biosphere continuously exchanges gases with the atmosphere. Human activities can also cause changes in land and water use. To the extent that the biosphere modifies the other components of the Earth system, it can also modify Earth’s climate. 7  What is It Activity: Think Globally, Act Locally In this activity, you will investigate Earth systems by making observations in nature and identifying systems in the natural world. Materials: Student Capture Sheet Guiding Questions What “systems” are found on Earth? How do Earth’s systems interact? Engage - Nature Walk Observations Procedures: 1. Take an outside nature walk for 5-10 minutes. As you walk, record at least five observations. What do you see? What’s going on outside today? What do you see happening in nature? Have you noticed any changes in nature around your home or school? Your observations might seem simple or obvious, but they will be important later on. 2. Look for the components of Earth systems (water, soil, air, living things, sun). Identify the system that each observation falls into on your data capture sheet. 3. Observe in more detail and describe the interactions between the systems. Write the observation. Draw arrows with notes explaining the connections between parts based on that observation. Observation System 1. 2. 3. 4. 5. 8  What’s More Continue your nature walk for few more minutes. Name something from each spheres of the Earth system (lithosphere, hydrosphere, biosphere, atmosphere) that you interact with every day. __________________________ _____________________________ __________________________ _____________________________ __________________________ _____________________________ Explain How do those things impact your life? ___________________________________________________________________ ___________________________________________________________________. After seeing many examples, what conclusions about Earth’s systems can you make? ___________________________________________________________________ ___________________________________________________________________. When human population in your study site increases, how would this affects the rest of the system? ___________________________________________________________________ ___________________________________________________________________. Interconnections and Processes Matter Transfer At the local level, there are many simple examples of interconnections between components and the elements of the Earth system. The roots of the plants (biosphere) draw water and nutrients from the lithosphere, exchange oxygen and carbon dioxide with the atmosphere through the process of photosynthesis, and send water into the atmosphere through the process of transpiration. Plants also die and decompose to become part of the lithosphere. Water evaporates from rivers (hydrosphere) and the soil (lithosphere) to become part of the atmosphere. Oxygen in the atmosphere dissolves in a river (hydrosphere). Fish (biosphere) draw dissolved oxygen into their bodies from the hydrosphere. Energy Transfer In addition to the exchanges of matter, the transfer of energy is a key process of the Earth system. The sun warms the lithosphere, which transfers its heat to the atmosphere; warmed air transfers heat to cooler land surfaces; evaporation from a 9 lake (hydrosphere) transfer heat to the atmosphere; rivers and ocean currents redistribute heat energy; precipitation can warm or cool the lithosphere on which it falls. Change Leads to Change Because of the interconnectedness, changes in one sphere bring about changes in the others. Sometimes these changes are dramatic. Droughts (atmosphere) can cause severe changes in the hydrosphere, the biosphere, and the lithosphere. Frequently these changes are more subtle. Heavy rain also changes the amount of soil moisture and frequent raining leads to erosions in the lithosphere. These are some examples of change in one sphere leads to change on the other spheres. What I Have Learned Hydrosphere is the total amount of water on a planet. The hydrosphere includes water that is on the surface of the planet, underground, and in the air. A planet's hydrosphere can be liquid, vapor, or ice. On Earth, liquid water exists on the surface in the form of oceans, lakes and rivers. Lithosphere is the rocky outer part of the Earth. It is made up of the brittle crust and the top part of the upper mantle. The lithosphere is the coolest and most rigid part of the Earth. The biosphere is a global ecosystem composed of living organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients. Atmosphere the gaseous envelope surrounding the earth; the air. What I Can Do Evaluate Match these words inside the box that correspond to the system below.
