Answer;

-Surface mining

Explanation;

-Mining involves the extraction of valuable minerals or other geological materials from the earth, commonly from an orebody, lode, vein, seam, reef or placer deposit. Despite having a large range of advantages economically, mining impacts the environment negatively because minerals are contained within the Earth. Earth must be removed in order to extract the minerals. When the minerals are close to the surface, the earth is removed, causing destruction to the shape of the land and the flora and fauna living in that area.

-Among different types of mining, surface mining is one of the method that greatly impacts the environment. It destroys all plant life in the area the mine occupies. Plants living in the area where the surface mine is to be located are removed. After the surface mine is no longer productive, plants may eventually return to the area, but typically some human efforts at reclamation are required to restore the environment to some level of productivity.

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.
