our changing earth, major diff - Coggle Diagram

- - - - natu formed diff ele of land
        
        moun, plain, plateau
  - - - breaking of rocks into small pieces
      - this breaking happens naturally because the rocks are exposed to extreme temp, rains, winds, and over period of time they break into small pieces
        
        formation of sediments
    - - process of moving this sediments to another place
        
        moving sedi to another place
      - moving is done by natural agents such as wind, water, ice etc
    - - these particles are delivered in a place and there a new landform is formed
    - - this process of weathering, erosion and deposition creates new land forms
- - - - these vibrations are called earth quakes
        
        these vib can tra all around earth
      - FOCUS: point where movement/vibra starts in earths crust
      - when lithospheric plates move earths surface vibrates
      - EPIC CENTER: palce above focus is called epic center
        
        greatest damage is possible at epic center
        
        strength of e.q decreases as it is moving away from epic cen
        
        WAVES: vibrations travel outwards epic center as waves
        
        types of waves
        
        S waves
        
        L waves
        
        P waves
      - prediction and prevention of earthquake
        
        e.q can be predicted in some cases and cant in another cases but we cant completely prevent e.q
        
        how can we predict earthquake
        
        by studying animal behaviour
        
        fishes coming of waterbodies to shores
        
        snakes coming to surface
        
        but we can minimize its damage if we take certain precautions or have certain preparedness
        
        precautions
        
        STAY AWAY FROM
        
        fire places
        
        f.p contain gases that reacts to fire easily
        
        if gas is leaked or gas pipe is collapsed there is cahnce of fire hazard
        
        mirrors and photo frame
        
        glass pieces may break and damage us
        
        BE PREPARED
        
        spread awareness amoung peolople instead of fear and face any disaster bravely
        
        CHOOSE SAFE SPOT
        
        under table or desk
        
        protects from falling objects or things
        
        corner of wall
        
        protect from building collapse
      - EARTH QUAKE MEASURING TOOLS
        
        SEISMOGRAPH
        
        used to measure vibrations of earth quake and helps to detect type of wave it is and its motion
        
        RITCHER SCALE
        
        used to determine magnitude of earth quake
        
        mag 5
        
        little damage
        
        things fall
        
        moderate earth quake
        
        mag 6
        
        very strong earth quake
        
        magnitude 2
        
        minor earth quake
        
        mag 7
        
        major earth quake
