Earth and Earth’s Subsystem Activity 2: On a clean sheet of bond paper, creatively draw the Earth and label each subsystem. Provide brief descriptions of each of the subsystems labeled.  EART -theH rd 3 planet in the solar system -it is said to be 4.56 billion years old, according to radiometric dating -revolves the Sun around 365-366 days -the only planet to harbor life. -habitable because of its location in the solar system, also called “the Goldilocks Zone”. also called “geoscience”, which EARTH is the study of the Earth’s characteristic behavior. Science EARTH SUBSYSTEM Is EARTH self sustaining? 1.Atmosphere 2.Hydrosphere CYCLE 3.Geosphere which is the process 4.Biosphere wherein the material in the Earth system was continuously recycled in numerous overlapping cycles. ATMOSPHER E set out layers of gases that 78% NITROGEN surrounds or protects that planet that is held by the planet’s gravity. 20.95% OXYGEN Earth’s Atmosphere are composed of: 0.93% ARGON 0.04% OTHER GASES  Layers of the Atmosphere Troposphere- where we live Stratosphere- which contains the ozone layer Mesosphere- where meteor burns Thermosphere- where satellites orbit the earth Exosphere- boundary between the Earth’s gaseous envelope to the vacuum of space. Atmospheric Circulation the cycle happening in the atmosphere that is the way of redistributing the heat from the sun to the surface of the Earth. Hydrosp here -the liquid component of the Earth (including glacial waters) -covers 70% of the Earth’s surface -98% of the water in the Earth is saltwater. -helps the atmosphere to become its currents state Hydrological Cycle (Water Cycle) - the cycle that explains the continuous movement of the water, above or below the Earth’s surface. -it also involves the transfer of energy (evaporation to condensation) -the sun is the driving agent of this cycle PROCESS OF WATER CYCLE 1. Evaporation 2. Condensatio n 3. Precipitation 4. Instillation Evaporation first major step in the TRANSPIRATI hydrological cycle; ON the sun is the driving type of water movement agent of this process for that is typically it will heat the water for happening in plants; it will become water the Sun absorbs the vapor; water from the aerial involves the molecular parts of a plant, like change of water form leaves, and it will liquid to gas. evaporate and will become water vapor. Condensation the reverse process of the evaporation; happening when the evaporated water vapor cooled down to its dew point; it is usually when the clouds are formed. Precipitation when water is released from the condensed clouds; the primary connection in the water cycle that provides for the delivery of the atmospheric water to the Earth. Types of Precipitation RAIN SNOW HAIL the solid type of the other type of water precipitation that has solid precipitation; droplets that a temperature of hails are small is responsible below 0-degree irregular lumps or for the bringing Celsius; balls of ice about the it is the ice crystal that size of 5mm to 15 cm; of freshwater precipitate from the usually occurs in into the Earth atmosphere; thunderstorms. it’s usually the precipitated in the polar regions or places with cold moisture.  Infiltration -the process by which precipitation or water was absorbed by the soil and moves into the rocks and usually replenishes the groundwater system. GEOSPHERE LITHOSPHE TECTONIC RE PLATES it is the solid state of the - is a part of the - these are the rocky Earth; geosphere that is parts of the composed of the lithosphere that are it includes solid, outermost part divided into structure, of the planet. numerous plates due composition, to the drifting of the minerals, and plates as time goes processes of by; estimated to Earth. move about 1-16 cm per year. Parts of the EARTH 1. CRUST 2. MOHO 3. MANTLE 4. OUTER CORE 5. INNER CORE  Crust TWO TYPES OF EARTH’S CRUST the Earth’s 1. Oceanic Crust -found in oceanic bases outermost and 2. Continental Crust – found beneath the thinnest layer; the continents. layer of the Earth where life exist; it comprises 1% of Earth’s volume; temperature ranges from 200 – 400 degrees Celsius MOHOROVICIC (MOHO) the boundary between the crust and the mantle; discovered by Croatian Seismologist Andrija Mohorovicic in 1909; showed there are two types of seismic waves: P- waves (Primary waves – first to arrive), S-waves (Secondary wave – second to arrive) Mantle also called “sima”; the biggest part of the Earth in terms of depth and volume; it is 2,900 km thick; average temperature is 3,000 degrees Celsius Outer Core it is a fluid (magma- like) part of the core; it is 2,890 – 5,000 km beneath the Earth’s surface; the temperature of the outer core ranges from 4,500- 6,000 degrees Celsius; this is the layer that creates the Earth’s magnetic field Inner Core the deepest part of the Earth and made up of iron and nickel alloy; the average temperature is 5,500 degrees Celsius; unlike the outer core, the inner core is solid due to the pressure crated by the total weight of the three other layers.  BIOSPHERE - it is the most important subsystem on Earth -it is the totality of all the ecosystems in the whole Earth -it drives us to be in constant need of interaction with the planet -coined by the Geologist Eduard Suess in 1875 INTERCONNECTEDNESS AND PROCESSES  QUIZ Direction: Choose the letter of the best answer. 1.
