I am a master at understanding the formation of sedimentary rocks!

• No, I need help!

• Kinda, I still need to study.

• Yes! I know exactly how sedimentary rocks are formed!

Sedimentary rocks take MILLIONS OF YEARS to form.

Sedimentary rocks are formed by...

• 1. Weathering- The rocks are weathered, or broken down. Las rocas se desgastan, o se quebran.

• 2. Deposition- The rocks start moving and build on top of one another. Sometimes dead animals and plants also build on top of the rocks. Las rocas se empiezan a mover y se amontonan. A veces plantas y animales muertos tambien se juntan en las rocas.

• 3. Compaction- The rocks build up with pressure. Las rocas se compactan y presionan.

• 4. Cementation- The rocks "glue" together. Las rocas se pegan juntas en el proceso de cementacion.

Sediments have layers! Los sedimentos tienen capas.

What are 2 important steps to form sedimentary rocks?

Cuales son 2 pasos claves para formar rocas sedimentarias?

FOSSIL FUELS / COMBUSTIBLES FOSILES

Fossil Fuels are found inside sedimentary rocks.

• There are 3 types of fossil fuels: COAL, OIL (PETROLEUM), AND NATURAL GAS. Hay 3 tipos de combustiles fosiles: carbon, petroleo, y gas natural.

• They are the remains of dead plants and animals. Son formados por plantas y animales muertos.

Coal / Carbon

• Coal is made up of only dead plants. Carbon se forma de plantas muertas.

• Coal is found mostly in swampy areas because of all of the plants and vegetation. Carbon se forma en pantanos por toda la vegetacion y plantas que se encuentran alli.

Oil and Natural Gas / Petroleo y Gas natural

• They are formed from dead animals AND plants. Se forman de plantas y animales muertos.

How do we know the answer is G?

Which other resource is also nonrenewable?

How do we know that the dead plants and animals became fossil fuels?

What does the word "burial" mean?

Landforms / Relieves de la Tierra

How are they formed? Ice, water, or wind?

Como se forman? Hielo, agua, o viento?

Canyon

They are formed by FAST-MOVING WATER -like a RIVER. This takes millions of years.

Cañones se forman por agua- como un RIO. Esto toma millones de años.

Delta

• It is caused when sediments DEPOSIT near a slow-moving river and the mouth of an ocean or sea. Se causa cuando sedimentos se depositan cerca de un rio y un oceano.

V-shaped valley

• It is formed by fast-moving water weathering, or breaking down, the rock.

• Se forma por agua rapida que desgasta, o quebra, las rocas.

• FORMED BY A RIVER/ FORMADO POR UN RIO

U-shaped Valley

• It is formed by a GLACIER, or ice, weathering the rock and forms a WIDE VALLEY.

• Se forma por un GLACIAR, o hielo, que desgasta las rocas y forma un VALLE ANCHO.

• FORMED BY A GLACIER

SAND DUNE / DUNA DE ARENA

• It is formed by WIND that deposits sediments and sand.

• Se forma por el VIENTO que deposita sedimentos y el viento.

•
