Question

Rocks are made of minerals, and they are formed in different ways.

According to the diagram above, how are igneous rocks formed?
A.
Other rocks experience intense heat and pressure.
B.
Molten rock cools and turns solid.
C.
Sand and other particles are buried, compacted, and cemented together.
D.
Wastes deposited by plants and animals decompose and weather.

Answer 1

The formation of igneous rocks, as depicted in the diagram, involves the cooling and solidification of molten rock, and the correct choice is option B. Molten rock cools and turns solid.

The correct answer is option B. "Molten rock cools and turns solid."

According to the diagram, igneous rocks are formed through the process of molten rock cooling and turning solid. Therefore, the correct answer is:

Explanation: Igneous rocks originate from the cooling and solidification of molten magma or lava. This process can occur beneath the Earth's surface (intrusive igneous rocks) or on the surface (extrusive igneous rocks). As magma or lava cools, minerals crystallize, forming the solid structure characteristic of igneous rocks. The diagram provides a visual representation of this formation process.
