Rock cycle Flashcards
What is the texture of metamorphic rock depend on?
Foliated.
What does metamorphic foliated do to the rock?
It has mineral grains and is in lines.
What is an example of metamorphic foliated example.?
Gneiss slate.
What is an example of a metamorphic non-foliated example?
Marble.
How are metamorphic rocks formed?
They are formed by heat and pressure.
What happens when heat and pressure happen to metamorphic rocks?
Rocks turn into new minerals and rocks.
Where does contact metamorphism form?
It forms near magma.
Where does regional metamorphism form?
It is formed deeper in the earth.
What is an extrusive igneous rock?
It is when magma comes out like lava and cools on the surface.
What is an intrusive igneous rock?
It is when magma cools off beneath the surface.
What are the properties of intrusive rock?
It cools slowly, course-grained, below surface large, visible, and cycles.
What is an example of intrusive rock?
Granite.
What are the properties of extrusive rock?
cools quickly, fine-grained, on the surface, small or no crystals.
What do all igneous rock begin as?
They begin as magma.
Why do igneous rocks have no fossils?
Because they would have melted in the magma.
What is an example of extrusive rocks?
Basalt pumice obsidian.
What clues would help you determine the type of igneous rock is where it was formed?
Weather is coarse or fine-grained as well as the type of rock.
How is sand formed?
Formed by the result of weathering of all three rock types.
What is weathering?
It is wind, water, ice, sunlight, and gravity.
What does weathering do to rocks?
It causes sediment.
What does erosion do?
It causes sediments.
What is deposition do?
It is where sediments finally land.
What turns sediments into sedimentary rock?
It compaction and cementation.
What is found in sedimentary rocks?
fossils.
What is an example of sedimentary rocks?
Limestone.
What is always happening to rocks?
rocks are always being recycled.
What is mechanical weathering?
It is the process that breaks rocks apart without changing their chemical composition.
What are examples of mechanical weathering?
It is freezing water, deep rocks in the earth under pressure, plants making cracks in cement, water wearing down rocks.
What are chemical waves?
It is water causes chemical weathering water/oxygen combines with iron to cause rust.
What are the sand colors?
orange, grey, violet, red. black, green, dark brown, pink, white, and tan.
What are some of the beach materials?
glass, shale, shells, volcanic minerals, and sand.
where are igneous rocks formed?
They are formed on volcanic surfaces or inside the crust.
What prosses create igneous rocks?
cooling of magma.
Where are sedimentary rocks formed?
They are formed near water.
What prosses create sedimentary rocks?
It is formed by compaction.
Where are metamorphic rocks formed?
It is formed on mountain ranges and deep in the earth.
What prosses create metamorphic rocks?
Heat and pressure from sedimentary rocks create metamorphic rocks.
What was the first part of the starburst lab?
Pulling it apart and making it sediments.
What was the second part of the starburst lab?
Applying heat and pressure makes it metamorphic rocks.
What was the third step in the starburst lab?
The third step was to heat for thirty seconds, making it into an igneous rock.
What is magma?
Magma is found beneath the surface of the Earth.
