Correct Answer:
B. Sedimentary Rocks
Correct Answer: Sedimentary Rocks
Sedimentary rocks are formed through the gradual accumulation, compaction, and cementation of sediments deposited in oceans, lakes, rivers, and other water bodies over millions of years. These sediments may consist of sand, silt, clay, shells, minerals, and organic matter. As additional layers accumulate, pressure compresses the lower layers, eventually forming solid rock. Common sedimentary rocks include sandstone, limestone, and shale. These rocks often contain fossils, making them valuable for studying Earth's geological history and the evolution of life. Sedimentary rocks cover a large portion of Earth's surface and are widely used in construction, cement production, and natural resource exploration.
