As rock is weathered it breaks down and erodes. Sedimentation begins where erosion stops. Erosion is
|
Transportation of rock particles via water wind or ice
|
The largest volumes of magma extruded on the continents are
|
Flood and plateau basalts
|
Our Earth has many resources, but they are not unlimited. In the case of abundant metals, supply will most often meet demand. However, problems can occurr when
|
All of these
|
If the rock particles in a sedimentary rock are relatively small and if the grains are well sorted and well rounded, we can infer that the sediment grains traveled a
|
Long distance for a long time
|
Limestone may be made up of
|
Shell fragments from marine animals
|
Contact metamorphic rocks are typically not foliated because
|
Contact metamorphism occurs from heat and not from deformation due to stress
|
Rocks are grouped into three classes depending on how the rock was
|
Formed
|
The first minerals to crystallize are those having the
|
Higher melting point
|
Silica has a relatively
|
Low melting point
|
Limestone may be metamorphosed into
|
Marble
|
Minerals are formed by the process of
|
Crystallization
|
Batholiths are massive plutons formed from the intrusion of
|
Granitic magma
|
As sediments accumulate, compaction and cementation produces sedimentary rock. This process is called
|
Lithification
|
The most common carbonate rock is
|
Limestone

Mauna loa is a

Shield volcano
