If a typhoon to the northeast derection which of the following could be the cause?​

Like any tropical cyclone, there are few main requirements for typhoon formation and development:

(1) sufficiently warm sea surface temperatures,

(2) atmospheric instability,

(3) high humidity in the lower to middle levels of the troposphere,

(4) enough Coriolis effect to develop a low pressure center,

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.
