Basalt, pumice and obsidian are examples of what type of rock?
extrusive igneous
intrusive metamorphic
extrusive sedimentary
The breaking down of larger rocks into sediments is called?
erosion
weathering
deposition
Water, wind,ice and gravity move rocks. This is called?
deposition
weathering
erosion
Any rock can change form into any other type of rock.
True
False
In the Starburst Lab, we made models of all types of rocks. Which type of rock is able to turn into a metamorphic rock?
Only sedimentary
Only igneous
Both igneous and sedimentary
Neither igneous or sedimentary
Rocks and sediment change as they move through the rock cycle. Which change involves turning into melting?
Lava to rock
magma to lava
rock to magma
rock to sediment
What must happen to a metamorphic rock before it becomes a sedimentary rock rock?
It must be broken down into sediment
It must be melted into magma
Its minerals must dissolve in water
It must be exposed to high temperature and pressure
As a result of cooling slowly, these rocks develop air pockets and are often very lightweight.
Sedimentary
Metamorpic
Intrusive Igneous
Extrusive Igneous
A student used a magnifying lens to examine two different rocks. Which crystals most likely formed from molten material that cooled rapidly?
crystals in rock 1, because large grains usually form near Earth's surface
Crystals in rock 1, because large grains usually form deep within Earth
crystals in rock 2, because small grains usually form near Earth's surface
crystals in rock 2, because small grains usually form deep within Earth
A sequence of mountain building is shown in the diagram. In the most recent phase, there are three spots designated (A, B, C). Which rock type would represent each of the letters in the bottom picture.
A-Metamorphic,B-Igneous, C-Sedimentary
A-Metamorphic,B-Sedimentary,C-Igneous
A-Igneous, B- Metamorphic, C-Sedimentary
A-Sedimentary,B-Igneous, C-Metamorphic
Which statement correctly describes the rock cycle?
Igneous rock can only form by heat and pressure.
Metamorphic rock can only form by crystallization.
Magma can only form by compaction and cementation.
Sediment can only form by weathering, erosion, and deposition
Which of the following processes is most necessary to form sedimentary rocks?
cooling
subduction
deposition
metamorphism
Shale is a rock formed when silt is compacted together. When shale is buried and experiences heat and pressure, it becomes slate. What type of change occurs in this process?
Sedimentary rock becomes metamorphic rock
Metamorphic rock becomes sedimentary rock.
Metamorphic rock becomes new metamorphic rock
Sedimentary rock becomes new sedimentary rock.
Granite is a rock formed from the cooling of magma. When granite is exposed to elements such as wind and water, it weathers and erodes and the particles are deposited. Pressure causes these and other particles to form sandstone at Earth's surface. What type of change occurs in this process?
Sedimentary rock becomes igneous rock
Igneous rock becomes sedimentary rock
Sedimentary rock becomes new sedimentary rock
Igneous rock becomes new igneous rock.
Which process can change metamorphic rock into new metamorphic rock?
The metamorphic rock undergoes cementation
The metamorphic rock melts and cools at Earth's surface
The metamorphic rock experiences increased heat and pressure
A certain rock formed on Earth's surface. Which of these conclusions can be drawn about the rock?
A. It must be an igneous rock
It cannot be an igneous rock.
It must be a metamorphic rock
It cannot be a metamorphic rock.
What do you need in order for igneous rock to form?
A volcano
A mountain
A glacier
A canyon
What do granite and basalt have in common?
They're sedimentary rocks
They're metamorphic rocks
They're igneous rocks
They're formed by erosion
What is the difference between magma and lava?
Magma is very hot, lava is cool.
Magma is molten rock within the earth; lava is molten rock on the earth's surface.
Magma is molten rock on the earth's surface; lava is molten rock within the earth.
Magma is cool, lava is very hot.
Which layer is the oldest?
A
B
C
D
