Ecology Chapter Parts of Earth

Solar System Earth is the third planet from the sun (3 rd rock) Mercury, Venus Earth and Mars are the inner planets (rock) Jupiter, Saturn, Uranus, and Neptune are the outer planets (gaseous) Each planet has unique characteristics

Earth The only know planet to support life (organisms) 1.Liquid water Temp depends on distance from sun Why is liquid water so important? 2.Layer of air around the planet Temp regulation Oxygen 3.Energy from the sun

Electromagnetic Spectrum

Earth’s 3 layers 1.Lithosphere 1.Land that forms the earth’s surface 2.Rocks, soil and sand 2.Hydrosphere 1.Water on the earth 2.Oceans, lakes, rivers, ground & clouds 3.Atmosphere 1.Air that surrounds the earth

1.2 Land and Water Lithosphere is between km thick Three types of rock 1.Igneous rock formed from cooled liquid rock 2.Sedimentary rock from layers of sediment –Fossils 3.Metamorphic rock changed by temp and pressure

Hydrosphere Over 70% of the earth is covered in water –97% salt water97% salt water –3% fresh 2/3 frozen ……… 1/3 liquid Fresh water a valuable resource! Ground water found in aquifers –Pumped to surface by man or nature –Refills slowly! May dry up if not careful Surface is lakes, rivers and run off
