sand or clay.
Igneous rocks are classified by
origin, texture, and mineral composition
Sedimentary rocks form from
Sediments by compaction and cementation, evaporation, and organic remains
Metamorphic rocks form from
other rocks by the action of heat and/or pressure (recrystallization)
type of rock formed as magma or lava (molten rock) solidifies from a rock that has been completely melted (comes from the Greek word fire)
Magma that reaches Earth's surface and it forms igneous rock
Igneous or molten rock beneath the earth's surface
formed from accumulation of fragments of other rocks or sediment or from chemical precipitants
salts and limestones are
chemical precipitants (when rocks comes from water)
water that has a lot of dissolved rocks into it
