Conical hills are common in volcanic areas Crater lake is formed along with the mouth of a conical volcano which is filled with water after cooling down of volcano. Due to repeated eruptions mouth of a volcano is converted into a large depression called a caldera. Lavashields are made by large amount of basic lava flows making volcanic shields with a gentle slope.
Lava plateau: is formed by large scale fissure eruptions covering extensive area e.g Columbia plateau in South America and the Deccan plateau of India.
