The Rock Cycle
1.
Which 2 processes result in the formation of igneous rocks?
Solidification and evaporation
Melting and solidification
Crystallization and cementation
Compression and precipitation
2.
Which 2 processes result in the formation of a sedimentary rock?
Folding and faulting
Melting and solidification
Compaction and cementation
heating and the application of pressure
3.
Which sedimentary rock most likely formed as an evaporite?
Siltstone
Conglomerate
Gypsum
Shale
4.
Metamorphic rocks result from
Erosion of rocks
Recrystallization of rocks
Cooling and solidification of molten magma
Compression and cementation of soil particles
5.
Which type(s) of rock can be the sources of deposited sediments?
Igneous and metamorphic rocks only
Metamorphic and sedimentary rocks only
Sedimentary rocks only
Igneous, metamorphic, and sedimentary rocks
6.
What do most igneous, sedimentary, and metamorphic rocks have in common?
They are formed from molten material
They are produced by heat and pressure
They are composed of minerals
They are found in distinct layers
7.
Metamorphic rocks form as a direct result of
Precipitation from evaporating water
Melting and solidification of magma
Erosion and deposition of soil particles
Heat and/or pressure causing changes in existing rock
8.
Which statement about rocks is true?
All rocks are formed from other rocks
All rocks except igneous rocks are formed from other rocks
All rocks except metamorphic rocks are formed from other rocks
All rocks except igneous and metamorphic rocks are formed from other rocks
9.
A clastic sedimentary rock may contain particles of
Other sedimentary rocks only
Metamorphic rocks only
Igneous rocks only
Any other kind of rock
10.
Igneous rocks form from magma which results from the melting of
Igneous rock only
Sedimentary rock only
Metamorphic rock only
Any kind of rock
