Butte - is a flat-topped rock or hill formation with steep sides caused by weathering and erosion from wind Canyon - A canyon is a deep valley with very steep sides caused by weathering and erosion from a river.
Cave - is a large hole in the ground or in the side of a hill or mountain caused by weathering and erosion of the rock material. Delta - is a low, watery landform at the mouth of a river. It is formed from sediments such as silt, sand and small rocks that are carried downstream in a river and are deposited where the river meets a body of water such as a gulf or the sea. A delta is often (but not always) shaped like a triangle (hence its name, delta, a Greek letter that is shaped like a triangle).

Hill – is a raised area or mound of land which can be cause by crustal movement due to earthquakes [constructive]; magma pushing up from under the earth [constructive]; or deposition [constructive] of material that has been weathered and eroded [destructive] from another location.
Mountain – is higher than a hill. The tallest mountain on Earth is Mt. Everest.

Valley – is a low place between mountains. Valleys can be caused by glaciers [destructive]; or by crustal movement due to earthquakes [constructive];
Volcano – is a mountain formed when magma and gases push up the overlying rock material [constructive]. Volcanoes can erupt, spewing lava, ashes, and hot gases from deep inside the Earth.
Bonus Word: Landslide – sudden collapse of land: the collapse of part of a mountainside or cliff; slow or rapid movement of a soil and rock mass down a slope, or for the mass itself. It covers a variety of processes and landforms known as rockslide, rockfall, debris flow, liquefaction, slump, earthflow, and mudflow.
Bonus Word: Creep - is the slow, down slope movement of soil under the influence of gravity. Bonus Word: Mudslide – a slowmoving and often destructive mass of mud flowing down a slope
Bonus Word: Slump – a slow movement of sinking or collapse of land area.
