Rock Cycle Processes

Lithification, Crystallization, and Heat and Pressure.

Which Process Forms Each of the Three Types of Rock?

Session Objective: (ILO)To help you demonstrate

an understanding of rock cycle processes that form each rock in the rock cycle, when asked what process: lithification, crystallization, or heat and pressure forms each type of rock, you will be able to describe each process that must occur for each rock to be formed without error.

What types of rocks are these?What are their names and charateristics?

Sedimentary Rock

• 1. Made from sediments weathered off of earth.

• 2. Have distinct layers.

• 3. Made by weight pressure of sediments on top of each other.

• 4. Some made by minerals that cement sediments together.

Characteristics:

Metamorphic Rock

• 1. Are morphed rocks.

• 2. Form deep in the earth by heat and pressure.

• 3.Rocks morph at 100 degrees Celsius.

• 4. The pressure comes from rocks above pressing down.

Characteristics:

Igneous Rock

• 1. Oldest kind of rocks.

• 2. Made deep within earth from magma.

• 3. Can cool inside earth (intrusive) and form crystals.

• 4. Can cool on earth's surface (extrusive) and are dark in color.

Characteristics:

Have you ever wondered where these three types of rocks came from?

How were they formed?

Well we are going to find out today!

What do you already know

about the three processes that must occur for these three rocks to be formed?

Describe parts of the processes that must occur to form sedimentary, metamorphic, and igneous rocks?

Process 1: Lithification

Formation of sedimentary rocks

• 1. Sediments are weathered, eroded, and transported to new areas mainly by water.

• 3.Sediments then are cemented together by dissolved minerals in water and are now actual rock.

• 2.Sediments are deposited and compacted together by pressure that squeeze the particles together for less open space.

Process 2: Heat & PressureFormation of metamorphic rocks

• 1. Form from other types of rocks.

• 2. Form under the surface where pressure is great.

• 3. Form where come in contact with magma, BUT CANNOT melt or would be igneous rock.

• 4. Formed by heat that morphs the original rock.

Process 3: Crystallization

• 1. Form from molten magma & lava.

• 2. Can form underground (intrusive) when magma gets trapped & cools slowly, forming crystals.

• 3.Can form above ground (extrusive) when volcanoes erupt & they cool fast forming black light rocks.

Formation of igneous rocks

Today's Activity: Rock Process Lab

Instructions:

• 4. Complete the questions on this worksheet: http://www.mtascience.com/rcws.pdf

• 5. We will go over the answers after everyone is done.

• 1. Make groups of 2 people, and go to a lab station.

• 2. Study the rocks given to you, and decided what rocks are which kind (sedimentary, metamorphic, or igneous).

• 3. Group the rocks with the label of the process (lithification, heat & pressure, and crystallization) that it must go through to be made.

Any Questions?

Come ask if you need help!
