Consider the following information : Name of the Landform | Type of Landform | Agent 1. Lapies | Depositional | Groundwater 2. Seif | Depositional | Wind 3. Horn | Erosional | Glacier In how many of the above rows is the given information correctly matched?

Lapies

• Lapies are irregular grooves and ridges formed on the surface of limestone when the rock is dissolved along joints by rain water and groundwater. It is therefore an erosional and not a depositional landform of karst topography. Hence, row 1 is not correctly matched.
• Stalactites, stalagmites and pillars are the depositional landforms of groundwater.

Seif

• Seif is a long, narrow, sword shaped longitudinal sand dune formed by the deposition of sand by wind in deserts. It is a depositional landform of wind. Hence, row 2 is correctly matched.

Horn

• A horn is a sharp, pyramidal peak formed when three or more cirques cut back into the same mountain by glacial erosion. The Matterhorn of the Alps is the classic example. Hence, row 3 is correctly matched.
