2Layers of the Earth
- Skin of the peach is the crust
- Meat of the peach is the mantle
- Pit of the peach is the core
3Layers 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
4TYPES OF ROCKS
- Igneous
- Sedimentary
- Metamorphic
5IGNEOUS ROCKS
- Formed from molten material including volcanic
lava, ash, or bombs as well as magma below
Earths surface
6TYPES OF IGNEOUS ROCKS
BASALT
GRANITE
7SEDIMENTARY 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
8TYPES OF SEDIMENTARY ROCKS
LIMESTONE
SHALE
COAL
9METAMORPHIC 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
10TYPES OF METAMORPHIC ROCKS
SLATE
MARBLE
11ROCK CYCLE
- The rock cycle is a never-ending process of rocks
forming, weathering, and changing into other rocks
