The primary difference between groundwater and wetland is that the groundwater exists beneath the surface of the Earth and the wetlands are formed above the surface of the Earth.
Explanation:
Both wetlands and groundwater are characterized by the presence of water. But the sources of water to both of them are different.
The water that has been trapped in the interiors of Earth during its formation and the water that seeps and percolates through the surface into the interiors of Earth is the primary source of groundwater.
The water that is left back in the nearby depressions or muddy lands by larger water bodies like seas and rivers are the primary source of water to the wetlands.
