Igneous
These rocks are formed inside the volcano.
Intrusive igneous rocks
What are the three types of classifications of sedimentary rock?
Clastic, Chemical, and Organic
Foliated metamorphic rock.
Water, wind, and ice can change the appearance of rocks by breaking them down gradually. What is the term?
Weathering ONLY!
What type of rock will you find in a structural basin such as the Mississippi River?
Sedimentary Rocks
Extrusive igneous rocks
These rocks are typically found in river deltas that have been created by sediment deposits.
Clastic sedimentary rock.
Which of the following is a metamorphic rock?
a. Gneiss b. Granite c. Rock Salt d. Limestone
A. Gneiss
When a rock reaches the magma chamber of a volcano it melts then returns to earth's surface where it cools. What type of rock has formed?
Igneous Extrusive OR Extrusive igneous (word for word)
The ocean floor is evidence that earth's surface and earth's interior might look different. What type of rocks are found there?
Igneous rocks
Which of the following rock is an extrusive igneous rock?
a. basalt b. sandstone c. marble d. limestone
a. basalt
These rocks are composed of carbon contained substances such as once-living organisms.
Organic sedimentary rocks
Marble is an example of what type of metamorphic rock?
Non-foliated metamorphic rock
The bottom layer of earth's crust will receive extreme heat from the mantle and pressure from rocks above it. What will this bottom layer become?
metamorphic rock
If metamorphic rocks are found deep within earth's crust, how do they get on earth's surface?
Through uplift. They are pushed onto earth's surface when tectonic plates collide causing mountains to form. Metamorphic rocks are typically found in mountains.
Which of the following is an intrusive igneous rock?
a. coquina b. coal c. granite d. scoria
Some sedimentary rocks are composed of layer of rock due to erosion and deposition. The Grand Canyon is a great example. What term is being described?: layer of rock
a. foliated b. non-foliated c. strata d. cementation
C. strata
Which of the following best defines metamorph?
a. to break down b. to change appearance c. to move from place to place d. to melt
b. to change appearance.
How does the cooling rate effect the texture of an igneous rock?
If the magma/lava cools quickly, the rock will form has bubble due to no time for crystals to form. When lava/magma cools slowly, the rock will form large crystals.
Subsidence is the sinking of the crust to lower elevations. Which is more likely to form?
a. volcanoes b. basins c. river deltas d. mountains
B. Basins
a. ocean floor b. basin c. river delta d. near volcanoes
A. ocean floor and D. near volcanoes.
Melissa poured Hydrochloric acid onto a rock she found near a beach. She noticed the rock fizzled. What type of rock did she find?
Chemical sedimentary rock
What happens to granite after heat and pressure?
a. becomes marble (foliated)
b. becomes marble (non-foliated)c. becomes gneiss (foliated)
d. becomes gneiss (non-foliated)
c. becomes gneiss (foliated)

Sediments deposit/cement to form igneous rocks
Like mid-ocean ridges, rift zones occur when earth's crust is pulled apart. The only difference is that they occur on land. What type of rock will form here?
Igneous rocks
