The correct answer is: A. sedimentary rocks.<\/p>\n
Limestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3). It is the most common sedimentary rock composed of carbonate minerals and is the second most common sedimentary rock overall. Limestone is the main component of chalk and calcareous mudstones.<\/p>\n
Sedimentary rocks are formed when materials are transported by water, wind, or ice and then deposited in layers. The materials that make up sedimentary rocks can be organic (such as plant or animal remains) or inorganic (such as minerals).<\/p>\n
Igneous rocks are formed when magma or lava cools and solidifies. Magma is molten rock that is found beneath the Earth’s surface. Lava is magma that has reached the Earth’s surface.<\/p>\n
Metamorphic rocks are formed when existing rocks are subjected to heat and pressure. The heat and pressure can cause the rocks to change their composition, texture, and structure.<\/p>\n
