A class is designing an outdoor model to show the geologic time scale from Precambrian time through the present. If they used a scale of 1m=100 million years, how long will their model be? Cenozoic Era= 66 million years
Mesozoic Era= 185 million years
Paleozoic Era= 291 million years
Precambrian Era= about 4,058

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.
