Igneous: These rocks are volcanic in nature. They are split into two categories in where they cool/crystallize: intrusive (internal) and extrusive (external). Intrusive volcanic rocks cool slowly, so they contain (usually) large crystals, like granites. Extrusive rocks are quite the opposite, in which they cool very quickly. This is where you get your obsidian glass and basalts. Sedimentary: These rocks are depositional and categorized by the kind of sediment it is made up of. Metamorphic: This can be the offspring rock of either a morphosed igneous or sedimentary rock. This metamorphism is accomplished by heat and/or pressure, and during a great length of time.

What distinguishes the three classes of rocks from one another?

There are three main types, or classes, of rock which are:***the differences among these rocks have to do with how they are formed as shown below****.sedimentary, these rocks are joining of pre existing rocks. is kind of like lumps of many small rocks.metamorphic: rocks that have changed due to then being moved or changed in any kind of way. these are the typeshe most rocks areigneous: these are formed by material that comes from the cooling and remains of magma. this is the least common form of rock.


Are rocks divided into three main classes?

Yes, rocks are commonly categorized into three main classes: igneous, sedimentary, and metamorphic. Igneous rocks form from the cooling and solidification of magma or lava, sedimentary rocks form from the accumulation and compression of sediments, and metamorphic rocks form from the alteration of existing rocks under high pressure and temperature.


What are the the three classes of rocks?

The three classes of rocks are igneous, sedimentary, and metamorphic. Igneous rocks form from the cooling of magma or lava, sedimentary rocks result from the accumulation and compression of sediment, and metamorphic rocks form from the alteration of existing rocks due to high heat and pressure.


Which two classes of rock will form near or at Earths surface?

Sedimentary rocks and igneous rocks are the two classes of rock that typically form near or at Earth's surface. Sedimentary rocks are created from the accumulation and consolidation of sediments, while igneous rocks are formed from the cooling and solidification of magma/lava.


Which major group of rocks are involved in Pathway 1?

Igneous rocks are the major group of rocks involved in Pathway 1. This pathway involves the formation of rocks from the cooling and solidification of magma or lava. Examples include granite and basalt.

What three major classes of rock would you expect to find as bedrock in Mt Shasta?

The three major classes of rock that you would expect to find as bedrock in Mount Shasta are metamorphic rocks, igneous rocks (such as andesite, dacite, and basalt), and sedimentary rocks. Metamorphic rocks would likely include schist, gneiss, and marble, while igneous rocks might be found in the form of lava flows and volcanic rocks. Sedimentary rocks like limestone and sandstone could also be present in the region.
