It is here to help you master the nature of Earth and Life Science. 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 focuses on the lesson: e Lesson 1 — Planet Earth After going through this module, you are expected to: 1. identify the characteristics of the Earth that supports life; and 2, expound how the characteristics of the Earth sustain the needs of a living organism.

DOnP> 3 CO_Q1_ELS SHS Module 1  Earth is the only place in the known universe confirmed to host life and is the only one known for sure to have liquid water in the surface. These are reasons why planet Earth is a unique one: (1) It has liquid water; (2) surface or lithosphere which includes the crust and the upper mantle; and (3) It has atmosphere that shelters it from the worst of the sun’s rays. Earth is the only planet in the solar system that has a large amount of liquid water. About 70% of the surface of the Earth is covered by liquid or frozen water. Because of this, Earth is sometimes called “blue planet.” Planet Earth is habitable because it has the right distance from the sun. It is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life including water and carbon. It can provide water, oxygen, useful biological products for human, and has suitable weather and climate. Earth, Venus, and Mars may have similarities: (1) They all are terrestrial planets, made of solid rocks and silicates; (2) They all have an atmosphere; (3) They all almost have the same time to rotate on their axes; (4) Earth and Mars both have water; (5) They all have carbon dioxide; and (6 All have landforms. Earth, Venus, and Mars have differences: (1) Venus has no water; (2) Venus and Mars don’t have oxygen; and (3) Earth has life forms.

Theclmates of Mars and CO_Q1_ELS SHS Module 1  What I Have Learned . Planet Earth is considered habitable because of the following reasons: (1) it has the right distance from the sun; (2) it is protected from harmful solar radiation by its magnetic field; (3) it is kept warm by an insulating atmosphere; and (4) it has the right amount of ingredients for life, including water and carbon, Earth is different from other planets in a way that it is the only planet with liquid water on the surface. a. Earth, Venus, and Mars may have similarities: (1) They all are terrestrial planets, made of solid rocks and silicates; (2) They all have an atmosphere; (3) They all almost have the same time to rotate on their axes; (4) Earth and Mars both have water; (5) They all have carbon dioxide; and (6) All have landforms. a. Earth, Venus, and Mars have differences: (1) Venus has no water; (2)Venus and Mars don’t have oxygen; and (3) Earth has life forms. What I Can Do “Terraforming Mars” Can man change or adjust Mars’ environment to make it more suitable for human habitation? How? List down your answer on the table. T.The first thing we would need to dois increase the planetary temperature. 1 2 |2.We could then introduce cyanobacteria to convert the atmospheric carbon dioxide into oxygen, and eventually nitrogen fixing organisms to convert ammonia into 3 |nitrogen. 4 |3.We could also mine nitrogen from the Venusian atmosphere. 5 4With the thicker atmosphere and subsequent higher temperatures, the ice Trapped at the poles wouid mett, likely covering the majority of the northern hemisphere in a vast ocean.
