MODULE 2 THE EARTH SYSTEM LEARNING OBJECTIVES ❑ Identify the four major components of the Earth system and give examples from their local study site ❑Infer connections among elements of the of each major components by describing connections at their local study site; and ❑Predict some ways that changes in one element of the study site might affect changes in other elements. LEARNING OBJECTIVES ❑ Identify the four major components of the Earth system and give examples from their local study site ❑Infer connections among elements of the of each major components by describing connections at their local study site; and ❑Predict some ways that changes in one element of the study site might affect changes in other elements.  GAME MECHANICS 1. Bring out your METACARD. 2.Each question represents different questions from your GRADE 1-5. 3.You will just raise your METACARDS if the teacher will say “RAISE YOUR METACARDS” 4.If the student will raise the METACARDS without waiting the word “RAISE YOUR METACARDS”,he/she will be DISQUALIFIED from that round. 5.The winners will have an ADVANTAGE to the NEXT ACTIVITY.  E ER PH OS RE M PHE ER E OS AT H SP RE HO HE BI SP RO LIT D HY  ATMOSPHERE This component is the blanket of BI gas that surrounds Earth. This distributes rain and traps OS LIT some of the heat radiated by PH ERE HO HY Earth to help keep us warm. ER D SP E H RO SP HE RE  ATMOSPHERE Its name rooted from the Greek word atmos which means gas and sphaira BI which means globe or ball. The air in the atmosphere is generally OS composed of 78% nitrogen, 21% PH LIT oxygen, 0.9% argon and the remaining ER 0.10% is made up of different trace gases HO HY E D SP and vapor H RO ER SP E HE RE  ATMOSPHERE Atmosphere is affected by the Earth’s gravity, so this is the BI reason why as the altitude OS HO SPH LIT increases the amount of gases in PH SPH ERE the atmosphere decreases. ER HY D E RO ER E  E ER PH ERE OS SP H RE HO HE BI SP RO LIT D HY  BIOSPHERE 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 LIT photosynthesis, respiration, decay, and human activity such as burning forests or HO HY fossil fuels, the biosphere continuously D SP exchanges gases with the atmosphere. H RO ER SP E HE RE  BIOSPHERE Biosphere came from the Greek word bios meaning life. It is composed of all living things and the areas where they are LIT found. It includes all animals, microbes, and plants. It extends to the upper areas HO HY D of the atmosphere where insects and SP H RO birds can be found. ER SP E HE RE  BIOSPHERE It is also in this zone that the interaction between the different subsystems is most dynamic. In LIT biosphere, each organism plays an important role to the food web. HO HY D If one is lost the others will be SP H RO affected. ER SP E HE RE  E H ER SP RE HO HE SP RO LIT D HY  LITHOSPHERE 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 HY core of the planet. Soil supports billions D of plants, animals, and microorganisms, it filters water, and it facilitates the RO decomposition of wastes SP HE RE  LITHOSPHERE It pertains to the solid part of the earth. It is HY divided in to three layers D such as the crust, RO mantle, and the core. SP HE RE  LITHOSPHERE It pertains to the solid part of the earth. It is HY divided in to three layers D such as the crust, RO mantle, and the core. SP HE RE  LITHOSPHERE It is composed of naturally occurring solid aggregate of minerals, organic material or natural glass called rocks. It is also composed of loose particles of rocks that enveloped the HY D surface of Earth called regolith. It contains all the soil, rocks, and RO SP minerals present in the crust to the HE core of the Earth. RE  RE HE SP RO HY  HYDROSPHERE 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.  HYDROSPHERE This includes ice, water vapor and liq water. The permanently frozen part o this subsystem is called cryosphere. Water on Earth is constantly and consistently moving because of temperature and salinity. It also plays an important role in absorption and redistribution of so radiation.  Driving Question: Do you think these EARTH SYSTEMS connected to each other? How?  The four subsystems are closely linked through the biogeochemical cycles which involves biological, geochemical, and chemical factors. These cycles are alleyways by which substances move through biotic which is the biosphere and abiotic which is the geosphere, atmosphere and hydrosphere, components of Earth. WHAT DO YOU THINK IS THE CONNECTION OF THE DIFFERENT THINGS SHOWN IN THE PICURE? WHAT DO YOU THINK IS THE CONNECTION OF THE DIFFERENT THINGS SHOWN IN THE PICTURE?
