Which of the following is an example of igneous rock?
Answer Details
An igneous rock is a type of rock that forms from the solidification of molten or partially molten material, such as magma or lava. Basalt is an example of igneous rock because it is formed by the rapid cooling of lava on the Earth's surface. As lava cools, it solidifies and hardens to form solid rock. Basalt is typically dark in color and has a fine-grained texture.
On the other hand, Dolomite, Limestone, and Marble are all examples of sedimentary rocks and metamorphic rocks respectively, and are not formed from solidified lava or magma. Dolomite and Limestone are formed from the accumulation of shells, coral, and other organic debris, while marble is formed from the metamorphism of limestone under intense heat and pressure.
