Which of the following describes humidity? The temperature of the air
The weight of the air pressing down on you
The amount of water vapor in the air
The direction the wind is blowing

Humidity describes the amount of water vapor in the air, and the more water vapor that is present, the more humid it is. ... This is the amount of water vapor in the air relative to what the air can hold. This is just like figuring out how much water is in a cup relative to the total amount of water that cup can hold.

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.
