Which one of the following rocks is used for monumental buildings? A. Granite B. Marble C. Sand stone D. Slate

Marble is a metamorphic rock that is formed when limestone is subjected to heat and pressure. It is a relatively soft stone that can be easily carved and polished, making it a popular choice for sculptures and other decorative objects. However, marble is not as durable as granite and is more susceptible to weathering and damage.

Sandstone is a sedimentary rock that is formed from sand grains that have been cemented together. It is a relatively soft stone that can be easily eroded, making it not a good choice for monumental buildings.

Slate is a metamorphic rock that is formed when shale is subjected to heat and pressure. It is a relatively hard stone that can be split into thin sheets, making it a popular choice for roofing and other applications where a flat surface is required. However, slate is not as durable as granite and is more susceptible to weathering and damage.
