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

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).
