If global warming continues, the glaciers will begin to melt and causing a rise in the levels of the oceans. If the global temperature increases just three degrees by the year 2050, the sea levels will rise 8 inches from the alpine glaciers alone. Aside from the sea level rising, the global temperatures and weather patterns would also change. Another gradational force is known as Mass Wasting. This is the movement of loosened rock and soil down a slope due to gravity, in the form of rock falls, mudflows, and landslides.
Deposition is the process of eroding sediment deposited elsewhere.
Erosion, another natural process that moves the fragmented rock and soil over a distance from the wind or water, this often causes rivers to flood over the banks depositing large bodies of silt onto the flooded land. Due to the repeated flooding of some rivers, the land surrounding the river flattens out, creating a flood plain. Then the flood plains often spread out in a triangular shape called a Delta. Deltas are built up from soil dumped when a river empties into a lake or ocean. Sandbars are offshore shoals of sand deposited with slower moving water.
