Notes:
Ox bow lake is a U shaped lake formed when a meander of a river is cut off. This cut off meander creates a free standing water body called Ox bow lake. Resacas are ox bow lakes left by Rio Grande.

Notes:
Karst topography is a result of the dissolution of soluble rocks like limestone, dolomite and gypsum. 
Caves are formed due to weathering of rock deep underground. Cave or cavern is a natural void and is  a space large enough so that a human can enter. Visiting or exploring caves for recreation is called caving, spelunking and potholing.

Notes:
Flat is a relatively level surface of land within a region of greater relief such as mountains or hills. They are a type of slope landforms.

Notes:
Asymmetric valley – A valley that has steeper slopes on one side is called an asymmetrical valley. They are Azonal landforms. They are associated with tectonic activity.
Mid oceanic Ridge – The underwater mountain system formed by plate tectonic spreading is called the Mid oceanic ridge. They are formed by plate tectonics due to the process of sea floor spreading. They are formed at divergent plate boundaries. They are the longest mountain ranges of the world.
Rift Valley – Rift valley is a type of a tectonic landform. It is a linear lowland formed by a tectonic rift or fault. It is formed on a divergent plate boundary.

Notes:
Volcanic landforms are features associated volcanic processes.
Graben – Graben is a depressed block of planetary crust bordered by parallel faults. Graben is a German word for ditch or trench. They occur side-by-side with Horsts. It is a tectonic landform.

Notes:
Panhole is a shallow depression or basin eroded into flat or gently sloping cohesive rock. Panholes are also called as armchair hollows, weathering pans, etc. They are well developed in granitic rocks and sandstone. They are commonly found in desert environments.

Notes:
