Activities, questions, directions, exercises, and discussions are carefully stated for you to understand each lesson. Each SLM is composed of different parts. Each part shall guide you step-by- step as you discover and understand the lesson prepared for you. Pre-tests are provided to measure your prior knowledge on lessons in each SLM. This will tell you if you need to proceed on completing this module or if you need to ask your facilitator or your teacher’s assistance for better understanding of the lesson. At the end of each module, you need to answer the post-test to self- check your learning. Answer keys are provided for each activity and test. We trust that you will be honest in using these. In addition to the material in the main text, Notes to the Teacher are also provided to our facilitators and parents for strategies and reminders on how they can best help you on your home-based learning. Please use this module with care. Do not put unnecessary marks on any part of this SLM. Use a separate sheet of paper in answering the exercises and tests. And read the instructions carefully before performing each task. If you have any questions in using this SLM or any difficulty in answering the tasks in this module, do not hesitate to consult your teacher or facilitator. Thank you.  What I Need to Know This module was designed and written with you in mind. It is here to help you master the nature of Biology. The scope of this module permits it to be used in many different learning situations. The language used recognizes the diverse vocabulary level of students. The lessons are arranged to follow the standard sequence of the course. But the order in which you read them can be changed to correspond with the textbook you are now using. The module is composed of: Lesson 1 – The Subsystems of the Earth After going through this module, you are expected to: 1. determine the four subsystems of the Earth; 2. describe the characteristics of each subsystem; 3. trace the flow of matter and energy in the Earth’s subsystems; and 4. express one’s internalized role as steward of the four subsystems concerning the flow of matter and energy. 1 CO_Q1_ELS SHS Module 2  What I Know Choose the letter of the best answer.

Earth is the only planet in the solar system with rain that falls from clouds, runs over the land, and collects in extensive oceans. It is also the only body we know that supports life. This self-learning module will help you understand the subsystem of the planet where you stand right now. What’s In Read the statement below and fill the table with the needed answers. Imagine walking along a rocky coast as a storm blows in from the sea. The wind whips the ocean into whitecaps, and waves crash onto the shore. Before you have time to escape, blowing spray has soaked your clothes. A hard rain begins as you scrambled over the rocks to your car. During the adventure, you have observed the spheres of the Earth. List down the terms that are used in the statement that reflects to what made up the Earth. Categorize them based on the following: Air Water Land With Life 4 CO_Q1_ELS SHS Module 2  What’s New Subsystems of the Earth Analyze and label the given picture. From the picture, create a general concept on each picture and identify the physical characteristics of the subsystem of the Earth. Differentiate one with the other. Write your answers on a separate sheet of paper. (A) (B) (C) (D) What is It Subsystems of the Earth The four subsystems of the Earth are: 1. Atmosphere – the gaseous layer above the Earth’s surface primarily composed of different gases such as nitrogen and oxygen. 2. Biosphere – the zone of the Earth where all forms of life exist. This serves as the ecosystem of all living and non- living organisms. 3. Geosphere – the solid part of the Earth that consists the entire planet from the center of the core to the outer crust. It includes core, mantle, and crust of the Earth. 4. Hydrosphere – the water part of the Earth that includes oceans and glaciers. 5 CO_Q1_ELS SHS Module 2  What’s More Activity 1.1 We are Connected! According to John Muir, “When one tugs at a single thing in nature, he finds it attached to the rest of the world.” How is the given diagram related to the said quote? How does the four subsystem of the Earth connect with each other? Write your answer on a separate sheet of paper. Geosphere What I Have Learned Subsystems of the Earth The four subsystems of the Earth are: 1. 1. Atmosphere – it is the gaseous layer above the Earth’s surface, primarily composed of 78% nitrogen and 21% oxygen. Other gases like argon, carbon dioxide, carbon monoxide, ozone, and other inert gases made the remaining 1%. The atmosphere supports life because animals and oxygen, and plants need both carbon dioxide and oxygen. In addition, the atmosphere supports life indirectly by regulating climate. Air acts as both a blanket and a filter, retaining heat at night and shielding from direct solar radiation during the day. 2. Biosphere – the zone of Earth where all forms of life exist: in the sea, on land, and in water. It is sometimes called as the large ecosystem. This is the zone that life inhabits. Biosphere is a very thin layer of the earth’s surface. 3. Geosphere – the solid Earth, consisting of the entire planet from the center of the core to the outer crust. It includes the core, mantle, and crust of the Earth. 6 CO_Q1_ELS SHS Module 2 4. Hydrosphere – the water part of the Earth which circulates among oceans, continents, glaciers, and atmosphere. Oceans cover 71% of the Earth and contain 97.5% of its water. Earth is a complex system made up of many smaller systems through which matter and energy are continuously cycled. Energy and matter flow through Earth’s spheres: geosphere, hydrosphere, atmosphere, and biosphere. Energy flows through the atmosphere mostly by convection. How does matter and energy flow across the four subsystems of the Earth? The Earth consists of four subsystems, across whose boundaries matter and energy flows, the atmosphere (air), biosphere (living things), hydrosphere (water), and geosphere (land). The atmosphere provides the geosphere with heat and energy needed for rock breakdown and erosion. The biosphere receives gases, heat, and sunlight (energy) from the atmosphere. It receives water from the hydrosphere and a living medium from the geosphere. What I Can Do The human population has increased rapidly since the 1700’s. For most of human history, there were fewer than half-billion people on Earth. In mid- 2009, 6.7 billion people inhabited our planet. Because of these, extensive pollution is everywhere. As a student, what can you do to save not only a particular system, but the Earth itself? Tabulate your answer on a separate sheet of paper. Copy the template below.
