Correct option is A
The correct answer is (a) Baikal rocks are formed from the dissolved materials that precipitate from the solution.
- The statement about "Baikal rocks" being formed from dissolved materials that precipitate from the solution is incorrect because there is no specific rock type known as "Baikal rocks." This term is not used in geology.
- The other options describe the formation processes of different types of rocks accurately:
- Sedimentary rocks are indeed formed by the deposition and cementation of material, usually in water bodies or on the Earth's surface.
- Metamorphic rocks are formed through the transformation of existing rock under high temperature and pressure, often deep beneath the Earth's surface.
- Igneous rocks are formed from the cooling and solidification of magma or lava.
Information Booster:
Sedimentary Rocks:
- Formed from particles of sand, shells, pebbles, and other fragments of material.
- Often found in layers and may contain fossils.
Metamorphic Rocks:
- Formed under the influence of high pressure, high temperature, or both, without the rock melting.
- Examples include marble and slate.
Igneous Rocks:
- Formed from the solidification of molten rock material.
- Can be intrusive (formed beneath the Earth's surface) or extrusive (formed on the Earth's surface).
