a stalagmite
Stalactites are cave formations that hang from the ceiling and are formed by the dripping of mineral-rich water containing calcite. Stalactites grow downwards over time as the calcite is deposited layer by layer.
A V-shaped valley is primarily formed by erosion, specifically by the action of a river or stream wearing away rock and sediment over time. The force of flowing water scours the landscape, carving out the valley shape. While some sediment may be deposited along the valley floor, the overall formation is due to erosion.
A spit is usually formed by longshore drift, where materials like sand and pebbles are deposited by waves along the coastline. Over time, these materials accumulate and extend out into the sea, forming a spit.
The flat, wide area along a river is called its flood plain. This is sometimes part of a larger area called the alluvial plain, which formed as the river shifted over time and deposited soil when it flooded.

You can notice sandbanks along many high tide bodies of water. These are formations that feature long wavelike patterns in the sand. Sandbanks are formed when sediments are deposited by waves and tides.
It is deposited on a sea or lake floor along with countless millions of similar grains. In time the deposit becomes compressed and de-watered by its own mass, and the grains may become cemented by silica or calcite, to turn it into rock.
calcite has a regular arrangement of atoms.
Spits form as a result of deposition by longshore drift, which is the movement of sand along the coast by the waves. The spit is formed when any material that is being carried by the waves gets deposited due to a loss of the waves energy, this could be because of a change of wind direction, or an estuary in the opposing direction slowing it down. As time progresses the deposited material forms a spit.
Calcite is the mineral that displays rhombohedral cleavage. Cleavage is the way a mineral breaks along certain planes of weakness, resulting in smooth, flat surfaces. In the case of calcite, it typically breaks along three cleavage planes at 75° and 105°, resulting in rhombohedral-shaped cleavage fragments.
The material eroded by the Colorado River is primarily deposited in the river's delta at the Gulf of California, as well as in various riverbanks, floodplains, and lakes along its course. Sediments accumulate in areas like Lake Mead and Lake Powell, created by dams, where flow velocity decreases. Additionally, the river's sediment can also contribute to the formation of sandbars and other landforms along its banks.
A beach is formed by both erosion and deposition. Waves erode the coastline by picking up and moving sand and sediment, which then gets deposited along the shoreline to create a beach. Erosion and deposition processes continually shape beaches over time.
