Laterite is a type of soil and rock rich in iron and aluminum, formed in tropical and subtropical climates through intense weathering of parent material. It is typically reddish-brown due to the high iron content and is often used as a building material, especially in regions where other resources are scarce. Laterite is commonly found in countries like India, Brazil, and Indonesia. It can be easily cut into blocks and is known for its durability. The presence of laterite can indicate a history of significant rainfall and warm temperatures, making it an important indicator of environmental conditions in a given area.
