Layers of the Earth
  • Skin of the peach is the crust
  • Meat of the peach is the mantle
  • Pit of the peach is the core

3
Layers of the EARTH
INNER CORE 800 miles thick and up to 13,000 F
CRUST 5 to 25 miles thick and up to 1,600 F
OUTER CORE 1,400 miles thick and up to 11,000 F
MANTLE 1,800 miles thick and up to 8,000 F
4
TYPES OF ROCKS
  • Igneous
  • Sedimentary
  • Metamorphic

5
IGNEOUS ROCKS
  • Formed from molten material including volcanic
    lava, ash, or bombs as well as magma below
    Earths surface

6
TYPES OF IGNEOUS ROCKS
BASALT
GRANITE
7
SEDIMENTARY ROCKS
  • Made of layers that have been pressed or cemented
    together
  • Pebbles, sand, silt, or clay are sediments
  • Shells and bones can also be sediments


8
TYPES OF SEDIMENTARY ROCKS

LIMESTONE
SHALE
COAL

9
METAMORPHIC ROCKS
  • Rocks that are changed by intense heat and
    pressure while inside Earths surface
  • Igneous, sedimentary, and even metamorphic rocks
    can be changed into different metamorphic rocks

    forming, weathering, and changing into other rocks
