Rocks that are created by the cooling of liquid magma are known as (explain)
a
Igneous rocks
b
Sedimentary rocks
c
Metamorphic rocks
The correct answer is a) Igneous rocks.
Igneous rocks are formed through the solidification and cooling of molten magma or lava. When magma cools and crystallizes underground, it forms intrusive igneous rocks. These rocks have a coarse-grained texture due to the slow cooling process. Examples of intrusive igneous rocks include granite and diorite.
When lava is ejected onto the Earth's surface through volcanic activity and cools rapidly, it forms extrusive igneous rocks. These rocks have a fine-grained texture due to quick cooling. Examples of extrusive igneous rocks include basalt and obsidian.
Igneous rocks can also be further classified based on their mineral composition and texture. They are an important part of the Earth's crust and have a variety of uses, such as construction materials and gemstones.
