So many misteries to solve
Canyons are bound by cliffs and cut by erosion,Canyons are really deep so I wouldn't want to fall of of one just saying !!! Layers of rock outline stories of regional geology like a table of contents in a scientific text.The most famous canyon is the Grand Canyon of course it is 277 miles 446 kilometers long MORE THAN 5000 feet 1500 meters deep wow!!!!!!!!!! Here is another picture of one.
A Glacier is a persistent body of ice that forms were accumulation of snow exceeds its ablation (melting and sublimation) over lots of years often centuries.Glaciers slowly deform and flow due to stresses induced by their weight creating crevasses and other distinguishing features .So it must be pretty!!!!!
to the mainland coast that protects the coast from the full force of powerful storm waves that's cool!!!! Between the barrier island and the mainland is a calm, protected body of water such as a lagoon or bay.Barrier islands are dynamic systems, constantly on the move wow it must get tired !!!migrating under the influence of changing sea levels, storms, waves tides and long shore currents. In the United states barrier islands occur offshore where gently sloping sandy coastlines as opposed to rocky coastline exist.
