This igneous rock is
obsidian
basalt
pumice
granite
All igneous rocks are formed from
cementing and compacting of rocks
heat and pressure within the Earth
the remains of ancient organisms
magma and lava
The size of crystals in Igneous Rocks depends upon
pressure
the presence of air
the presence of water
cooling rate
All rocks are classified based upon
the way they are formed
the elements they contain
the latitude and longitude where they are formed
the layers that are present
The color of an Igneous rock tells about the rock's
location
texture
cooling rate
composition
Igneous rocks are classified based upon their composition and
size
texture
layers

granite
gabbro
rhyolite
sandstone
Mafic rocks are
light in color due to high silica content
