This Self-Learning Module (SLM) is prepared so that you, our dear learners, can continue your studies and learn while at home. 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.
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.
The sun supplies energy to Earth that is necessary for its survival. The heat of the sun is too much to bear if not because of a blanket of air that surrounds the Earth we call atmosphere. The atmosphere is not just a layer of air or gases but it is more than that. It contains the oxygen that we breathe; it allows us to communicate; and it has the ozone layer that protects us from harmful solar radiation.
A lot is happening in the atmosphere such as weather system and the atmospheric phenomena caused by the sun or solar energy. Therefore it is necessary that one should be familiar with the structure and composition of the atmosphere. One then can give reasons for the weather events as well as global atmospheric phenomena like greenhouse effect and global warming that result from changes in the composition of the gases of the atmosphere brought by some human activities.
How is Earth’s atmosphere affected by solar energy? This module will guide you in understanding how energy from the sun interacts with the layers of the atmosphere. You will learn more about earth’s atmosphere -the place on earth that is vital to our existence.
Most Essential Learning Competency:
- Discuss how energy from the sun interacts with the layers of the atmosphere.
This module is divided into two lessons:
- Lesson 1: Layers of the Atmosphere
- Lesson 2: Greenhouse Effect
After going through this module, you are expected to:
1. explain the basis for the division of the layers of the atmosphere;
2. describe the features of each layer of the atmosphere;
3. describe greenhouse effect;
4. identify the sources of greenhouse gases; and
5. cite ways on how to slow down the effects of global warming.
