The rock formed from the solidification of molten matter (magma) is called: A. Sedimentary rock B. Metamorphic rock C. Igneous rock D. None of the above

Sedimentary rock
Metamorphic rock
Igneous rock
None of the above

The correct answer is C. Igneous rock.

Igneous rocks are formed when molten rock (magma or lava) cools and solidifies. The magma can come from deep within the Earth’s mantle or from volcanoes. When magma cools slowly underground, it forms intrusive igneous rocks. When magma cools quickly on the surface, it forms extrusive igneous rocks.

Sedimentary rocks are formed when pieces of other rocks, minerals, or organic matter are compacted together and cemented. The pieces can come from the weathering and erosion of existing rocks, or from the remains of plants and animals. Sedimentary rocks are classified based on the size of the pieces that make them up, the way the pieces are arranged, and the type of material that makes them up.

Metamorphic rocks are formed when existing rocks are subjected to heat and pressure. The heat and pressure can cause the rocks to change their shape, size, and composition. Metamorphic rocks are classified based on the type of rock that they were originally, and the type of metamorphism that they underwent.

None of the above is not a correct answer.
