Sedimentary
Contains sediments
Sediments can include:
mud, sand, pebbles, shells, bones, leaves, stems and other remains of living thingsSlide4
This is breccia, a type of sedimentary rock. See the “pieces” in the rock. These are pieces of broken rocks. These pieces get “cemented” my minerals.

This is sandstone. It is made of small, sand sized weathered rock.

This is coal. This is an “organic” sedimentary rock. It is made from dead plants. Thick layers of dead plants form, and the pressure compacts it into a rock.

What do you think is the definition for sedimentary rock?Slide8
Sedimentary Rock
Definition
Type
of rock formed by compacting and cementing of
sediments
Draw a picture to help you remember the definition and rate your level of understandingSlide9
Igneous Rock
Write the term and what you believe it to meanSlide10
Igneous
These are made from molten rock
Some form underground and are called “intrusive igneous rocks”
Some form above ground and are called “extrusive igneous rocks”Slide11
This is basalt. It is mostly made of the minerals plagioclase and pyroxene. It commonly forms as an extrusive rock such as a lava flow.

This is pumice. It forms after a very fast solidification of the melt (it goes from a liquid to a solid quickly!) It has holes because gas was trapped in the melt when it became a solid.

This is pegmatite. It is an intrusive igneous rock. It forms near the margins of a magma chamber and contains rare minerals not found in other parts of the magma chamber.

Metamorphic Rock
Write the term and what you believe it to meanSlide17
Metamorphic
Extreme heat, pressure, and chemical process alter the mineralogy, texture, and chemical composition of rocks
There are foliated metamorphic rocks which have a banded appearance and are created by heat and pressure
Non-foliated metamorphic rocks are not bandedSlide18
This is gneiss. It is a foliated metamorphic rock that is made up of granular mineral grains. It usually has quartz and feldspar minerals.

This is marble. It is a non-foliated metamorphic rock that is a metamorphism of limestone.

This is schist. It is a foliated metamorphic rock. It contains a lot of mica which allows it to split into thin pieces.

Metamorphic Rock
Definition
Type of rock that is changed due to chemical reactions, heat and/or pressure
