Laterite
What is Laterite?
Laterite is a soil type rich in iron and aluminum, formed in hot and wet tropical areas. It results from intense and prolonged weathering of the underlying parent rock. The weathering process causes the leaching of silica and other soluble materials, leaving behind the less soluble iron and aluminum oxides. This gives laterite its characteristic reddish-brown color. Laterite is porous and can be easily cut, making it suitable for construction. However, it can also harden upon exposure to air, forming a durable material.
