Classifying Rocks
A natural, solid mixture of minerals and grains.
Una mezcla sólida y natural de minerales y granos.
It is called this when it is on Earth's surface and something else when it is under the Earth's surface.
Se llama así cuando está en la superficie de la Tierra y de otra forma cuando está debajo de la superficie de la Tierra.
Lava when on Earth's surface and magma when it is under Earth's Surface.
Lava cuando está en la superficie de la Tierra y magma cuando está debajo de la superficie de la Tierra.
What is sediment?
These small pieces (rocks, plants, animal organisms) that break off of the earth because of wind and water erosion.
quartzite, marble, slate
Geologists classify rocks into these 3 major groups.
What are igneous, sedimentary, and metamorphic rocks?
The type of rock that forms from magma or lava cooling is called this./ El tipo de roca que se forma a partir del enfriamiento de magma o lava se llama así.
Igneous rock/ Roca ígnea
What are the crystals like in an extrusive rock?
¿Cómo son los cristales en una roca extrusiva?
Small or impossible to see with the human eye
Pequeño o imposible de ver con el ojo humano.
Name two examples of sedimentary rocks.
Sandstone, shale, limestone, conglomerate
What does MORPH mean?
To undergo transformation or change.
A rock transforms to sediment by these two processes.
What are weathering and erosion?
This type of rock forms from sediments being compacted and cemented together.
Este tipo de roca se forma a partir de sedimentos que se compactan y cementan juntos.
Sedimentary/ Sedimentario
Igneous rock that formed from magma and cooled very slowly UNDERNEATH the earth's surface.
Intrusive
Name two characteristics of sedimentary rocks.
Chunks of sediment, fine grains, layers, fossils
How do metamorphic rocks form?
They are sedimentary or igneous rocks that are near magma and get heat from it and pressure from layers above.
DAILY DOUBLE!!! I have a sedimentary but then extreme heat and pressure are applied to it. What type of rock will it change into?
Tengo un sedimentario pero luego se le aplica calor y presión extremos. ¿En qué tipo de roca se convertirá?
A metamorphic rock
Una roca metamórfica
This type of rock needs heat and pressure to form./ Este tipo de roca necesita calor y presión para formarse.
Metamorphic Rock/ Roca metamórfica
From lava ON the earth's surface.
Sedimentary rocks usually have crystals? T or F?
BLACK HOLE QUESTION ... lose 100 pts
bummer.
I have a metamorphic rock that melts, then cools and crystallizes. What type of rock will it turn into?
Igneous Rock
Roca ígnea
What are the two characteristics geologists use to identify rocks?
¿Cuáles son las dos características que usan los geólogos para identificar rocas?
Texture and Composition
This igneous rock is very light, has holes in it, and can float in water./ Esta roca ígnea es muy ligera, tiene agujeros y puede flotar en el agua.
Pumice
How do sedimentary rocks form?
The sediment falls to the bottom of the ocean, and is cemented together over 1000s of years.
What would have to happen to a metaphoric rock in order for it to change into sedimentary rock?
¿Qué tendría que pasar con una roca metamórfica para que se convierta en roca sedimentaria?
Weathering and erosion
