1. EARTH AND LIFE SCIENCE GRADE 11 QUARTER1_W1_D1

2. Objective: Recognize the uniqueness of the earth, being the only planet in the solar system with properties necessary to support life

3. WHAT MAKES EARTH SO PERFECT FOR LIFE FORMS? the first things came up in our mind that a terrestrial planet where all forms of life: from basic living micro-organisms to highly sophisticated and intelligent human beings exists. In this write-up, we discussed the factors that are responsible for the existing life on the Earth.

4. DISTANCE OF EARTH FROM THE SUN The Earth and the Sun are equally important because without the Sun's heat and light , the Earth would be a lifeless ball of ice-coated rocks. It regulates the temperature of water bodies, weather patterns and provides energy to the growth of plants.

5. Earth’s Atmosphere

6. EARTH’S ATMOSPHERE It is the layers of gases surrounding the earth that consists of exosphere, thermosphere, mesosphere, stratosphere and troposphere. The air content and favourable atmospheric pressure also supported life of most creatures.

7. CLIMATIC CONDITION The Earth has a suitable climate for the existence of all forms of life because of moderate amount of carbon dioxide, which is the driving factor for the survival of life forms. The temperature of planet Mercury ranges from 200°c below freezing to 375°c above. At 375°c, the water would only exist as a gas, and the planet would be completely dry.

8. WATER Water is very important for life because it contains the oxygen needed for life and allows life-providing molecules to move around easily. It continually changes its form through the water cycle. The process by which water continually changes its form and circulates between oceans, atmosphere and land is known as the water cycle.

9. GRAVITY The Sun's gravitational pull keeps our planet orbiting the Sun and the Earth firmly hold everything from topography to all forms of life through its gravitational pull. The force of gravity does not just keep us anchored to the ground, but also affects our biological system.

13. Objective Explain that the Earth consists of four subsystems, across whose boundaries matter and energy flow.

14. GEOSPHERE The solid portion of the earth that includes interior structure.

15. Atmosphere: volcanism spews significant amounts of gases into the atmosphere. For example, volcanoes inject large amounts of sulphur dioxide to the upper atmosphere, resulting in global cooling. Hydrosphere : The formation of many minerals involve incorporation or release of water. Also, water speeds up chemical reactions that produce or destroy minerals, and aids in the melting of rock. Biosphere : Nutrients released from rocks during their breakdown are dissolved in water (to be used by aquatic plants).

16. HOW GEOSPHERE INTERACTS WITH OTHER SUBSYSTEm

17. Atmosphere the layers of gases surrounding a planet or other celestial body .

18. Hydrosphere: The gases of the atmosphere readily exchange with those dissolved in water bodies (e.g. oceans, lakes, etc.) Biosphere: The atmosphere supplies oxygen and carbon dioxide that form the basis of life processes (photosynthesis and respiration). Geosphere: Gases in the atmosphere react with water to produce weak acids that aid in the breakdown of rock.

19. BIOSPHERE The life zone

20. Atmosphere: Life processes involve a many chemical reactions which either extract or emit gases to and from the atmosphere (e.g. photosynthesis consumes carbon dioxide and releases oxygen, whereas respiration does the opposite). Hydrosphere: Evaporation of water from leaf surfaces (transpiration) transfers water to the atmosphere. Geosphere: The biosphere is connected to the geosphere through soils (mixtures of air, mineral matter, organic matter, and water). Plant activity (e.g. root growth and organic acid production) are also for the mechanical and chemical breakdown of the rocks.

21. HYDROSPHERE contains all the water found on our planet. Only about 3% of the water on Earth is “fresh” water, and about 70% of the fresh water is frozen in the form of glacial ice.

22. Atmosphere: Water is transferred between The hydrosphere and biosphere by evaporation And precipitation. Energy is also exchanged iN This process. Biosphere: Water is necessary for the transport of nutrients and waste products in organisms Geosphere: Water is the primary agent for The chemical and mechanical breakdown of rock (weathering), to form loose rock fragments and soil, and sculpts the surface of the Earth .

31. EARTH AND LIFE SCIENCE GRADE 11 QUARTER1_W1_D4

32. ROCK TYPES OBJECTIVE: Students may be abled classify rocks into igneous, sedimentary, and metamorphic

33. IGNEOUS forms when molten rock (magma) cools and hardens  CLASSIFIED BY WHERE THEY FORM AND CRYSTAL (GRAIN SIZE)

34. SEDIMENTARY ROCKS Sedimentary rock : forms from the compaction and/or cementation of sediments This process is called lithification Sediments are: Rock pieces Mineral grains Shell fragments Sedimentary rock can also form from the chemical depositing of materials that were once dissolved in water

35. METAMORPHIC ROCKS Metamorphic rock : forms when any rock type is changed into a different kind of rock Changes due to great heat and/or pressure

36. ANSWER THE FOLLOWING
