Rocks and Rock cycle
ROCKS ON THE EARTH 1. Igneous rocks 3. Sedimentary rocks
ROCK CYCLE Magma of the interior is uplifted cooled-s& again uplifted. If instead of upliftment, it again goes inside the earth then due to high temp& pressure chemical composition of the rock changes this are metamorphous rocks . Metamorphous ->change from original form .Due to erosion of uplifted igneous & metamorphic rocks by means of agents like air, wind, waves etc. ->pebbles->granules->sand-> de- position of sand Due to deposition lowermost layer feels pressure & forms sedimentary rocks .

Igneous rocks Formed due to solidification of magma . Don't have strata or layer Don't have strata or layer . No fossils (due to high temperature) . Entire lava is solidified therefore they have crystalline structure
Extrusive igneous rocks cool quickly and as a result these rocks are fine grained or has lack of crystal growth. Intrusive igneous rocks are formed from magma that cools slowly and as a result these rocks are coarse grained. Magma chamber
Sedimentary rocks . Formed due to lithification of soil Erosion of rocks->deposition of sand->compressed & compacted always in layers can find fossils here
