The geographical conditions of the Harappan civilisation were conductive for human habitation and settlement. The seals discovered from the sites of the civilisation reveal many animal figures. Majority of these animals could exist only in moderate climatic conditions. Therefore, it can be assumed that the climate during the Harappan period was moderate and not extreme. The lands around the Indus river were extremely fertile. The floods that occurred every year made the alluvial soil more fertile and well irrigated. These geographical factors helped in the growth the development of the Harappan civilisation.
