Sorting Rocks
Sedimentary, Igneous,
and Metamorphic
Rocks
Sedimentary Rocks
 Wind
and water break rocks into
small pieces.
 The small pieces settle at the
bottom of rivers and oceans.
 These layers of sediment harden to
form sedimentary rocks.
Sedimentary Rocks
Sandstone
Limestone
Shale
conglomerate
Igneous Rocks
 Melted
rock called magma is deep
within the earth. When magma
comes up through the openings in
the Earth’s crust, it is called lava.
 Lava cools to form hard, igneous
rocks
Igneous Rocks
 Granite
basalt
 Obsidian
pumice

Metamorphic
Rocks
Heat and pressure deep inside the
Earth can cause igneous and
sedimentary rocks to change.
 Rocks that are changed are called
metamorphic rocks.
Metamorphic Rocks
 Slate
marble
 Schist
gneiss
