Sedimentary rocks
You find a sedimentary rock near a stream with sediment "glued" together. What type of sedimentary rocks did you find?
Clastic sedimentary rocks
What two processes need to happen to turn a rock metamorphic or sedimentary rock into an igneous rock?
Melting and cooling
What two processes need to happen every time to make a metamorphic rock?
Heat and pressure
What is the rock cycle?
The processes in which one type of rock becomes another.
How hot is magma?
1000 Degrees celcius
Coal and limestone are both sedimentary rocks that formed from once living things. What type of sedimentary rocks are these?
Organic sedimentary rocks
Lave erupts from a volcano and begins to cool quickly. What type of igneous rock is being formed?
Extrusive igneous rock
You have a rock heat up and have pressure applied to it turning into a metamorphic rock. I continues to heat up until it melts. If this still a metamorphic rock?
No
You have a metamorphic rock slowly over time turn into a sedimentary rock. What are the 5 processes that made this happen?
WEDCC's
You have a tree root breaking down a rock as it grows. What process is happening to the rock?
Weathering
Stalagmites and stalactites are sedimentary rocks that form in caves when water evaporates and leaves sediment behind. What type of sedimentary rocks are these?
Chemical sedimentary rocks
magma gets trapped under the earth and begins to form slowly, making crystals in the process. What type of igneous rock is being formed?
Intrusive igneous rock
You have a metamorphic rock that does not have any consistant lines to it. What type of metamorphic rock do you have?
Nonfoliated metamorphic rock
You have a sedimentary rock turn into an igneous rock and then with time turn into a metamorphic rock. What are all the steps that this rock went through to make this happen?
Melting and cooling, heat and pressure
You find a rock with fossils of shells and fish bones. They are not distorted in size. Based on this information what type of rock did you find?
Organic sedimentary rock
Name three agents of weathering
ice, water, wind, tree roots, gravity
You have a metamorphic rock begin to get so hot that it melts into magma and then with time it erupts out of a volcano and cools. what process did this rock take to become and igneous rock.
Melting and cooling
You find a metamorphic rock that seems to have wavey lines that came about from heat and pressure. What type of metamorphic rock do you have?
Foliated metamorphic rock
What is the only type or rock that can't form deep beneath the earth?
Sedimentary rocks
Which is the best answer that describes what most rocks are made of?
A. sediment
B. Ice
C. Minerals
D. Sand
C. Minerals
You have granite (intrusive igneous rock) turn into sandstone (clastic sedimentary rock) over time. What are the five steps granite took to become sandstone?
Weathering
Erosion
deposition
compaction
cementation
You have a dark colored igneous rock formed with a large amount of magnesium. What type of igneous rock is this?
Mafic igneous rock
Heat and pressure is needed to form a metamorphic rock. What are the two ways that pressure is applied to this rock?
Tectonic plates and gravity
You have a conglomerate clastic sedimentary rock weathered down and deposited with limestone turning it into an organic sedimentary rock as it is all compacted. You then have the same rock dissolve in water and then the water evaporates away. What type of rock do you have?
Chemical sedimentary rock
Sandstone and Limestone are both sedimentary rocks used every day by humans. What is one option we don't use them for?
A. Construction
B. Medical tools
C. Gravel
D. Landscaping
B. Medical tools
