correct Answer: (B) only Key Point Playa, (Spanish: shore or beach), also called pan, flat, or dry lake, flat-bottom depression found in interior desert basins and adjacent to coasts within arid and semiarid regions, periodically covered by water that slowly filtrates into the groundwater system or evaporates into the atmosphere, causing the erosion of salt, sand, and mud along the bottom and around the edges of the depression. A playa is a dry, vegetation-free, flat area at the lowest part of an undrained desert basin. It is a location where ephemeral lakes form during wet periods and is underlain by stratified clay, silt, sand, and commonly, soluble salts. A pinnacle, tower, spire, needle, or natural tower in geology is an individual column of rock, isolated from other rocks or groups of rocks, in the shape of a vertical shaft or spire. swallow hole A natural depression or erosional hole in the Earth's surface, also known as a sink, shake hole, sinkhole, swallow hole, swallet, doline, or cenote, is mostly caused by karst processes - the chemical dissolution of carbonate rocks or suffusion processes for example in sandstone. Additional Information All are depositional landforms. A fjord is a long, deep, narrow body of water that reaches far inland. Fjords are often set in a U-shaped valley with steep walls of rock on either side. Fjords are found mainly in Norway, Chile, New Zealand, Canada, Greenland, and the U.S. state of Alaska. Drumlins are oval-shaped hills, largely composed of glacial drift, formed beneath a glacier or ice sheet and aligned in the direction of ice flow. A levee is a natural wall that blocks water from going where we don't want it to go. Levees may be used to increase available land for habitation or divert a body of water so the fertile soil of a river or sea bed may be used for agriculture. That is Natural levees. Cirques are bowl-shaped, amphitheater-like depressions that glaciers carve into mountains and valley sidewalls at high elevations. Often, the glaciers flow up and over the lip of the cirque as gravity drives them downslope.
