Earth’s continents are constantly in motion because they sit on top of gigantic plates which float on earth’s mantle. energy from the earth’s core creates convection currents in the molten layer, and the currents move the plates. over extremely long periods of time, this movement creates new a. biomes b. plates c. atmospheric layers d. elements

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.
