Choose all of the following that apply to the top layer of the soil profile
it is the layer that contains the most organic material
it is the layer that contains the least organic material
it is the layer that formed last, and is the most recent layer to have formed out of all the soil layers
it is the layer that formed First, and is the oldest layer to have formed out of all the soil layers
it is the layer that has the least parent material/bedrock, out of all the layers in the soil profile
Organic matter in soil is made from
carbon dioxide
acid rain
decayed plants and animals
weathered parent rock

The picture shows what happens to the water table when water is pumped out of a well, a cone of depression forms. If the water is constantly being pumped out of the ground from the well during a time of little recharge/drought, which of the following is most likely to happen?
The Water Table will go down, and the Zone of Aeration will increase.
The Zone of Aeration will get smaller.
The picture above will remain the same during times of drought and flooding..
The Water Table will rise, and the Zone of Saturation will increase
Select all of the choices that are examples of Chemical Weathering
Select all of the features that are examples of Karst Topography
Many people in Virginia rely on well water pumped from aquifers for for drinking. Aquifers are a valuable resource that must be kept clean for all to use. All of the following would negatively affect an aquifer except-
Leaking barrels of oil seeping into the ground.
Excessive farm waste from animals infiltrating into the ground.
thunderstorm passing over an area that is capable of producing averages of 2-3 inches of rain an hour.
Over pumping of water out of an aquifer during times of drought.
In the diagram, the zones of saturation is marked number

Many homes in Virginia rely on groundwater for drinking. Some areas across the state are better than others to pump water out of for drinking. Select the best characteristics below that would be ideal for an aquifer to pump water out of.
Low Porosity
High Porosity
Low Permeability
High Permeability
There are many cargo ships travel from the Atlantic Ocean, through the Chesapeake Bay, and up the James River to Deepwater Terminal in Richmond. The level at which the cargo ships float, drops as they go from the Atlantic Ocean to the James River. What is the reason that the level at which the cargo ships floats in the water changes when it goes from the Atlantic Ocean to the James River?
The temperature of the water changes from the Atlantic Ocean to the James River
The volume of the water changes from the Atlantic Ocean to the James River
The density of the water changes from the Atlantic Ocean to the James River
The barometric pressure of the water changes from the Atlantic Ocean to the James River
