  1. EARTH AND ITS COMPOSITION BY- AKANKSHA SONI


  2. PHYSICAL CONDITION OF EARTH'S CRUST Earth has a layered structure that is Core, Mantle and Crust and they are classified on basis of behavior of seismic waves e Earthquake waves- Originate during earthquake deep inside earth.The place where originate is Focus and surface above focus of earthquake is Epicentre * P-wave shadow cone S-es -> Travela in dolid- and Liquid -> Faster in Solid than longitud waves S-wave shadow sone 105"


  3. EARTH'S STRUCTURE Temperature and density is increasing from crust to core. solia bite CRUST Outer core- Pressure i:s comparatively less allowing iron to melt. Important for magnetism LM CROSE- SECTION Mantle- Semi solid state and main source of magma Crust+ Upper mantle= Lithosphere. or Aaled
