Can someone explain how mountain chains provide evidence to support the theory of continental drift? my sister has been begging me to ask someone. : p

Well, mountain ranges are a result of two plates colliding, pushing the earth up and out of the water as they overlap.  The continental drift occurred because plates moved apart from each other and collided elsewhere.

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.
