$\bf{Characteristics \: of \: Igneous \: rocks\huge\red↓}$

$\bf\circ$These rocks are massive means very hard and compact means close together .

$\bf\circ$These rocks are formed by the cooling and bardening of the earth material .

$\bf \circ$All igneous rocks are crystaline in nature and their size depends upon the rate of cooling of lava and magma .

$\bf \circ$Igneous rocks do not have layers and do not contain fossils .

$\bf \circ$These rocks are not easily weathered . Because there are no pores so water cannot easily enter .
