Question

Process of transformation of existing rocks is known as ______________.
A) Metamorphism
B) Hypabyssal
C) Abyssalism
D) All of the above

Answer 1

Hint: Igneous, sedimentary, and metamorphic rocks are the three types of rocks. When magma or lava from volcanoes cools, it forms igneous rock. Basalt and granite are two examples. The majority of igneous rock is extremely hard.

Complete answer:
Let us analyze the given options:
Option A) Metamorphism: Metamorphism is a mineral assemblage and texture modification process that occurs when solid rocks undergo physical-chemical changes as a result of events such as crust movement, magma activity, or thermal fluid change in the earth. So, it is a process of transforming of existing rock. Hence, this option is correct.

Option B) Hypabyssal: A subvolcanic rock, also known as a hypabyssal rock, is an intrusive igneous rock emplaced at medium to shallow depths within the crust with grain size and structure that is intermediate between volcanic and plutonic rocks. So, it is not a process of transforming of existing rock. Hence, this option is incorrect.

Option C) Abyssalism: Abyssalism is a religion that developed from the death and destruction caused by the various wars fought throughout the universe's history. The Abyssal worship Abyssalism, which literally means "wicked heart," "bad god," and "evil design." The Swastika is the Abyssalism's major logo. So, it is not even a process of transforming rocks. Hence, this option is incorrect.

Option D) All of the above: We already know that option A. Metamorphism is the correct answer, hence the option is incorrect.

Therefore, Option A. Metamorphism is the correct answer because Metamorphism is the term for the transformation of existing rocks.

Note: Metamorphic rocks can originate in three different ways. Contact, Regional, and Dynamic metamorphism are the three types of metamorphism. Contact When magma collides with an already existing body of rock, metamorphism occurs.
