• Environmental Science


  The study of nature and the facts about the environment
• Environmental Engineering


  The branch of engineering concerned with protecting the environment by providing solutions to environmental problems
• Environment components


  Biotic and abiotic components
• Panchaboodas


  Ancient term for environment
• Ecosystem


  • Self-regulating group of biotic communities of species interacting with one another
• Structure of ecosystem


  • Abiotic or non-living components
  • Biotic or living components
  • Energy components
• Abiotic components


  Enter the body of living directly or indirectly
• Abiotic components


  • Atmosphere
  • Hydrosphere
  • Lithosphere
• Structure of atmosphere


  • Troposphere
  • Stratosphere
  • Mesosphere
  • Lonosphere
  • Exosphere
• Function of atmosphere


  • Maintaining heat balance on the earth by absorbing radiation
• Structure of the Earth

  • Crust
  • Mantle
  • Core
• Components of ecosystem


  • Abiotic environment
  • Producers
  • Consumers
  • Decomposers
• Producers


  Autotrophs - nourishing themselves
• Consumers


  Heterotrophs - nourishing on others
• Decomposers


  Mainly microorganisms like bacteria
• Cycles in ecosystems


  • Biogeochemical cycles
  • Geophysical cycles
  • Hydrologic cycles
  • Chemical cycles
• Biogeochemical cycles


  Cyclical pathways by which a given substance flows through the different components of an ecosystem
• Geophysical cycles


  Earth's physical cycles
• Hydrologic cycle


  Deals with water after touching the surface
• There are many chemical cycles
• Chemical cycles


  • Carbon
  • Nitrogen
  • Sulfur
  • Phosphorus
• Biodiversity


  Abbreviated word for "Biological Diversity" - variety of life in our planet
• Biomes


  Considered life zones, environments with similar climatic, topographic, and soil conditions that compared biological communities
• Levels of biodiversity


  • Ecosystem
  • Species
  • Genetic
• Ecosystem is one level of biodiversity
• Species is one level of biodiversity
• Genetic is one level of biodiversity
• Metamorphic Rock


  Rocks that are formed from the transformation of existing rocks due to heat and/or pressure
• Rock Cycle


  The continuous process of rock formation, transformation, and reformation
• Types of Rock


  • Igneous
  • Sedimentary
  • Metamorphic
• Igneous Rock


  Rocks that are formed from the cooling of magma or lava, which then crystallizes and solidifies
• Igneous Rocks


  • Intrusive (formed from the cooling of magma deep within the Earth's crust): Granite, Pegmatite, Diorite, Gabbro
  • Extrusive (formed from the cooling of lava on the Earth's surface): Rhyolite, Obsidian
• Sedimentary Rock


  Rocks that are made up of pieces of other rocks and are formed by the accumulation and consolidation of sediment
• Sedimentary Rock Formation


  • Erosion
  • Transportation
  • Deposition
  • Compaction
  • Cementation
• Sedimentary Rocks


  • Limestone
  • Arkose
  • Sandstone
  • Conglomerate
  • Chert
• CINZOUS


  A mnemonic for remembering the three types of rocks: Igneous, Sedimentary, Metamorphic

  A mnemonic for remembering the steps in Sedimentary Rock formation: Erosion, Transportation, Deposition, Compaction, Cementation
• Metamorphic rock


  Rocks that are changed due to extreme heat or pressure
• Metamorphism


  Rocks subjected to great heat or pressure
• Rock cycle


  • Weathering
  • Erosion
  • Sedimentation
  • Compaction
  • Cementation
