Atrench is evidence of which kind of plate boundary? 1) uniform 2)divergent 3) convergent 4) transform

A trench is evidence of (3) Convergent plate boundary

Explanation:

Trenches are formed by subduction a geophysical process which involves the converging of two or more Earth's tectonic plates and the older denser plate is pushed beneath the lighter plate and deep into the mantle causing the seafloor  and outermost crust to bend and form a steep V shaped depression.

Geological features which occur at convergent boundary are as following:

Fault lines : A transform boundary connnects two diverging boundaries creating a fault lineTrenches: They are formed by convergent boundariesVolcanoes: results from subduction zoneMountain RangesRidgesRift valleys

Wetlands form where water and land meet. a lake with a wetland fringe can fill in with decayed plant and animal material to become a wet meadow. a pond can fill in to become a bog or fen. sediment can fill in a river marsh to become a swamp.flooding of coastal lowlands from rising sea levels has created broad coastal marshes that are protected from wave action by barrier islands or reefs. coastal wetlands also form when rivers deposit sediment as they reach the ocean. plants then take root and hold the soil firm against the forces of tides and waves.
