The process by which water, wind, ice, and changes in temperature BREAK DOWN rock into fragments called sediments.

This rock was formed by smaller pieces of rock that settled at the bottom of a lake millions of years ago. What type of rock is this?

This rock was found near the mouth of a volcano. What type of rock is this?

You find a rock in which the grains are arranged in parallel bands of white and black crystals.  The rock is probably a(n)

Small pieces of rock are also called

original form by immense heat or pressure

Which rock type is typically formed under the surface of the Earth?

Crystals forming from magma

Moving wind, water, and glaciers carrying sediment from one place to another

The transformation of an existing rock to a rock with a different texture, structure, or mineral composition by extreme heat and pressure

Igneous rocks that cool underground

Igneous rocks that cool above the surface

The creation of rocks from sediments

Sedimentary rocks that form from minerals that precipitate from salt water

Rich in magnesium and iron, tend to be dense and darker in color, generally associated with oceanic crust

Rich in feldspar and quartz, tend to be less dense and lighter in color, generally associated with continental crust

Occurs when magma touches a rock

Occurs over a wide area when great masses of rock are exposed to pressure from sediment and rock layers on top of it

The layered or banded structure found in some rocks due to the alignment of minerals under pressure
