Which of the following best describes the texture of an igneous rock that originated at a great depth?
The kind of rock that forms when lava cools slowly and slowly deep inside the crust is known as intrusive or plutonic rock. The phaneritic or coarse-grained texture of the intrusive igneous rock is the result of the lengthy cooling process, which permits crystals to develop to their full size. The individual crystals that make up the phaneritic texture may be seen quite clearly even without the help of a microscope.
How would you describe the consistency of igneous rock that was created underground?
Igneous rocks with a phaneritic texture have big crystals that are visible to the naked eye since the rock evolved gradually in an underground magma chamber.
What kinds of igneous rocks are generated deep inside the earth?
Igneous rocks may be broken down into two primary categories: plutonic rocks and volcanic rocks. The subsurface cooling and solidification of magma results in the formation of plutonic rocks.
What are the results of the formation of rocks at such a depth?
In contrast to metamorphic and igneous rocks, which are generated far deeper inside the Earth, sedimentary rocks are formed either directly on or very close to the surface of the planet.
The grain size of the sediment that was deposited to produce rock unit 2 is the subject of the second question.
less than 0.0004 centimeters
Which mineral is present in biotite mica as well as muscovite mica, and which mineral accounts for the biggest percentage of the volume of the Earth’s crust?
Q4 Determine the relative color and density of this igneous rock in comparison to mafic igneous rocks with the same crystal size by analyzing the minerals that are present in the rock.
less dense in appearance, lighter in color
Q5 The beach is made of of particles that range in size from 0.01 cm to 0.1 cm in diameter. Determine the kind of sedimentary rock that will be produced as a result of these sediments being buried and cemented together.
The answer to question six is rock salt, which is formed when a certain mineral precipitates in seas.
The majority of rocks that are classed as having formed from fragmental rock particles include
sedimentary composed of clastics
In question 8, the rock that had been melted began to solidify.
fast, leading in the formation of minerals with very small grains
Which kind of metamorphic rock is most likely to have been formed in the zone where the Palisades sill and the sedimentary rock came into contact with one another?
Identify two elements that are present in all three of the minerals listed in the table below for the tenth question.
