This is a wetland marsh composed of a mixture of both salt and freshwater (brackish water). 

• estuary

• river

These are the three main jobs of wetlands.

• provide habitats, store flood waters, purify water
• provide habitats, store plant life, purify water
• purify water, store wildlife, provide habitats
• purify the land, store flood waters, provide habitats

Wetlands store flood waters. How is this beneficial? Choose the best answer.

• Its not really beneficial because this may flood peoples homes.
• It releases the water is increments which will really increase the wildlife in that area.
• It releases the water is increments which slows the water down thus slowing erosion.
• Its really not beneficial because this will flood the habitats of the wildlife living there.

Which description below best describes how wetlands purify water?

• Wetlands slow down the water flow when the water encounters the vegetation. This allows the sediments and pollutants to drop out of the water before the water moves on.
• Wetlands don't really purify the water. They just slow it down and the heat from the Sun makes it hot enough to purify the water before it moves on.
• Wetlands slow down the water flow so that sediments and pollutants can drop out of the water before it moves on.
• Wetlands can't really purify the water because they release the water in large increments which doesn't allow enough time for it to be cleaned.

These are all examples of natural causes of wetland loss.

• storms, subsidence, tectonic activity, and sea level rise
• channelization, invasive species, and man-made levees
• storms, channelization, tectonic activity, and invasive species
• invasive species, natural levees, storms, and sea level rise

These are ways humans contribute to wetland loss.

• channelization, invasive species, and man-made levees
• man-made levels, channelization, and storms
• invasive species, natural levees, and drilling for oil & gas
• drilling for oil & gas, storms, and channelization

All of the following are animals found in the wetlands EXCEPT...

• frog

• turtle

• mosquito

• polar bear
