What is the main type of eruption that formed the volcano in this photograph?
The type of volcanic eruption shown in this photograph is: a pyroclastic column.
What does the texture of this rock indicate about its cooling history the magma cooled?
The texture of an igneous rock is determined by the cooling history of the magma from which it formed. … Phaneritic texture describes coarse grained rocks. They are characteristic of intrusive (plutonic) rocks and have crystals that can be seen with the unaided eye. Indicates slow cooling history.
Which of the following is a common metamorphic process?
The most common process in the formation of metamorphic rocks is recrystallization. In this process, small crystals of one mineral in contact with one another slowly come together to form fewer larger crystals. For example, the sedimentary rock, limestone.

How does metamorphic rock look like?
Metamorphic rocks were once igneous or sedimentary rocks, but have been changed (metamorphosed) as a result of intense heat and/or pressure within the Earth's crust. They are crystalline and often have a “squashed” (foliated or banded) texture.
Which feature is created on the exterior of a volcano when it erupts?
Lava Domes-Lava domes form where thick (viscous) magma erupts to the surface forming a steep dome-shaped landform. Lava domes can form within a crater of large composite volcano.
What are the main types of volcanic eruptions discuss in brief the resulting features?
Types of eruptions
- Hydrothermal eruption. An eruption driven by the heat in a hydrothermal systems. …
- Phreatic eruption. An eruption driven by the heat from magma interacting with water. …
- Phreatomagmatic eruption. …
- Lava. …
- Strombolian and Hawaiian eruptions. …
- Vulcanian eruptions. …
- Subplinian and Plinian eruptions.
What are the characteristics of intrusive igneous rocks extrusive igneous rocks?
The two main categories of igneous rocks are extrusive and intrusive. Extrusive rocks are formed on the surface of the Earth from lava, which is magma that has emerged from underground. Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet.
How does the rate of cooling affect the formation of intrusive igneous rocks of extrusive igneous rocks Brainly?
Extrusive igneous rocks cool much more rapidly than intrusive rocks. The rapid cooling time does not allow time for large crystals to form. So igneous extrusive rocks have smaller crystals than igneous intrusive rocks.
What are the types of metamorphic rock?
Common metamorphic rocks include phyllite, schist, gneiss, quartzite and marble. Foliated Metamorphic Rocks: Some kinds of metamorphic rocks — granite gneiss and biotite schist are two examples — are strongly banded or foliated.
What is metamorphic process?
Metamorphism is a process that changes preexisting rocks into new forms because of increases in temperature, pressure, and chemically active fluids. Metamorphism may affect igneous, sedimentary, or other metamorphic rocks.
What type of rock is metamorphic?
Common metamorphic rocks include phyllite, schist, gneiss, quartzite and marble. Foliated Metamorphic Rocks: Some kinds of metamorphic rocks — granite gneiss and biotite schist are two examples — are strongly banded or foliated.
How can you identify a metamorphic rock?
Metamorphic rocks are rocks that have become changed by intense heat or pressure while forming. One way to tell if a rock sample is metamorphic is to see if the crystals within it are arranged in bands. Examples of metamorphic rocks are marble, schist, gneiss, and slate.
What is metamorphic rock type?
Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
What Colour is metamorphic?
It is usually gray in igneous rocks; gray, white, yellow, or red in sedimentary rocks; and gray or white in metamorphic rocks.
Which feature is created on the exterior of a volcano when it erupts magma chamber crater hot spot?
Lava Domes-Lava domes form where thick (viscous) magma erupts to the surface forming a steep dome-shaped landform. Lava domes can form within a crater of large composite volcano.
What are features of volcanoes?
Landform-scale, volcanic geomorphologic features include lava flows and related features (diverse types of scarps, levees, and lava flow surface features); lahars, calderas, the diverse types of cones and related rims, necks, domes, tubes, trenches, fissures and scarps.
What are the features of a volcano?
The main features of a volcano include the magma chamber, vents, craters and slopes. The diagram below shows the main features of a volcano. The magma chamber is a large underground pool of magma. Under pressure, the magma in the chamber can rise up the main vent, which is the central tube through the volcano.
What type of volcanic eruption occurs when magma gets in contact with water resulting in the emission of pyroclastic materials?
phreatic eruptions Volcanic eruptions arise through three main mechanisms: Gas release under decompression, causing magmatic eruptions. Ejection of entrained particles during steam eruptions, causing phreatic eruptions. Thermal contraction from chilling on contact with water, causing phreatomagmatic eruptions.
What are the characteristics of igneous sedimentary and metamorphic rocks?
Igneous rocks are formed from melted rock deep inside the Earth. Sedimentary rocks are formed from layers of sand, silt, dead plants, and animal skeletons. Metamorphic rocks formed from other rocks that are changed by heat and pressure underground.
What are metamorphic rocks characteristics?
Metamorphic rocks were once igneous or sedimentary rocks, but have been changed (metamorphosed) as a result of intense heat and/or pressure within the Earth's crust. They are crystalline and often have a “squashed” (foliated or banded) texture.
How does the rate of cooling affect the formation of intrusive igneous rocks of extrusive igneous rock?
Extrusive igneous rocks cool much more rapidly than intrusive rocks. The rapid cooling time does not allow time for large crystals to form. So igneous extrusive rocks have smaller crystals than igneous intrusive rocks.

What are the types of metamorphism?
The three types of metamorphism are Contact, Regional, and Dynamic metamorphism. Contact Metamorphism occurs when magma comes in contact with an already existing body of rock.
What are the features of metamorphic rocks?
The main feature that identifies metamorphic rocks is that they are shaped by great heat and pressure. The following traits are all related to that. Because their mineral grains grew together tightly during metamorphism, they're generally strong rocks.
What are some features of metamorphic rocks?
Metamorphic rocks were once igneous or sedimentary rocks, but have been changed (metamorphosed) as a result of intense heat and/or pressure within the Earth's crust. They are crystalline and often have a “squashed” (foliated or banded) texture.
What are the 3 types of metamorphic rocks?
There are three ways that metamorphic rocks can form. The three types of metamorphism are Contact, Regional, and Dynamic metamorphism. Contact Metamorphism occurs when magma comes in contact with an already existing body of rock.
