1.
What are the two types of igneous rocks?
a)
foliated and non foliated
b)
intrusive and extrusive
c)
Clastic and organic
d)
Chemical and extrusive
2.
How are the two types of igneous rocks different?
a)
The size of the crystals and the time it takes the molten material to cool
b)
The size of the crystals and the pattern of crystals
c)
One type is exposed to more heat and pressure than the other type
d)
Some contain fossils and others do not
3.
What percentage of the earth's crust is made up of igneous rock?
a)
20 %
b)
50%
c)
95%
d)
75%
4.
What have we learned in class that would explain why so much of the earth's crust is igneous?
a)
Weathering and erosion creates sediments which is the most common rock type
b)
Hot spot volcanoes erupt basaltic lava and form new land.
c)
when plates move they create different kinds of rocks like metamorphic and sedimentary rocks these are the most common on the ocean floor
d)
oceanic crust is created at the mid-ocean ridge and is basalt. Continental crust consists of granite which is cooled deep within the earth's crust
5.
How would an intrusive igneous rock become a sedimentary rock?
a)
The rock would undergo extreme heat and pressure deep in the earth where it would turn into a sedimentary rock.
b)
The rock would melt under extreme heat and then erupt from a volcano and cool into sedimentary rock
c)
The rock would undergo uplifting to reach the surface where they would be weathered and eroded into small particles then they are deposited compacted and cemented into sedimentary rock.
d)
The rock would undergo uplifting to reach the surface where it would be exposed to lava flows which would eventually create a sedimentary rock
6.
What can metamorphic rock help scientists learn about the interior of the earth?
a)
They can learn about the density and temperature by studying metamorphic rock at different locations
b)
They can learn about the temperature and pressure by studying metamorphic rock at different locations
c)
They can learn about the density and state of matter by studying metamorphic rock at different locations
d)
They can learn about the density and pressure by studying metamorphic rock at different locations
7.
How would an igneous rock become a metamorphic rock?
a)
The rock would undergo extreme heat and pressure deep in the earth where it would turn into a metamorphic rock.
b)
The rock would melt under extreme heat and then erupt from a volcano and cool into metamorphic rock
c)
The rock would undergo uplifting to reach the surface where they would be weathered and eroded into small particles then they are deposited compacted and cemented into metamorphic rock.
d)
The rock would undergo uplifting to reach the surface where it would be weathered and eroded then exposed to lava flows which would eventually create a metamorphic rock
8.
What are some uses for igneous rock?
a)
To help scientists understand the earth's internal temperature and pressure
b)
So scientists can figure out the age of earth
c)
Buildings such as the Vietnam Veterans Memorial in Washington DC
d)
As a source of metal such as iron and copper.
9.
Under heat and pressure granite becomes which type of metamorphic rock?
a)
sandstone
b)
Gneiss
c)
limestone
d)
marble
10.
Over thousands of years rocks change from igneous to metamorphic to sedimentary depending on certain events. What do we call this constant change from one type of rock to another?
a)
weathering and erosion
b)
heat and pressure
c)
Rock cycle
d)
Geologic cycle
100 %
