B) Materials in Solution is NOT a process of a stream load Streams must start somewhere. Streams are formed by having
sufficient water supply. The supply comes from rainfall and
underground reservoirs. The area that initiates the stream
supply is called the headwaters. Many times headwaters start
in the high elevations. As the water moves down through the
mountains, the stream’s pathway is formed. As streams evolve, the path of the stream starts to curve. The
curving of a stream channel is known as a meander. As meanders
develop, they become broader and larger. Eventually,
there are enough material deposits to form a blockage of two
meanders. This development causes the formation of an
oxbow lake.
Convection is a process which transfers the heat between the temperatures when fluid (i.e. liquid or gas) is in motion. Due to the presence of heat source, water temperature increases and also it will become less dense and rise. Hot air is less dense than cold. When air rises higher in the atmosphere its pressure gets down and it becomes colder.
D - Mongolia. This is because it is a landlocked country which means it is only surrounded by countries, not oceans. Therefore, it would not have access to big oceans/seas.
