Why do commercial airliners encounter very little turbulence above 25,000 feet? A) Water vapor has mostly disappeared at colder elevations and its effect on weather turbulence.
B) The air is so thin at altitudes above 25,000 feet that turbulence has much less effect.
C) There are no clouds above 25,000 feet.
D) The jet stream produces a much smoother flow of air.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
