Karst topography is a landscape or landform created when nearby groundwater or surface water dissolves rocks. Examples of karst topography include caves and sinkholes, as shown in the images. sinkhole near a home, a huge sinkhole in a habited region, and a man standing inside a cave

Based on your experimental results, what can you conclude about the type of rocks that once existed in these locations and the acidity of the nearby groundwater?

In my own word cell technology can  lead to advances in the understanding of diseases mechanism and transmission because diseases is very bad

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.
