What are the two types of groundwater?
The two types of groundwater are: Wells and Aquifers.
Where do groundwater and runoff usually end?
Groundwater and runoff are two different things. Groundwater refers to water underground in the aquifers. Runoff ends up back underground by seeping into the soil after a rain. Runoff may also find its way into ditches, retention ponds, lakes,etc.

When groundwater that flows in an aquifer between two layers of impermeable rock is forced to the surface by an increase in pressure .what is formed?
artesian well
What is the boundary surface between two different rock types or ages of rocks?
An inhumed erosional surface that splits two strata of dissimilar ages or two rock masses is called unconformity. Generally, the older layer was exposed to erosion for a period of time before depositing the younger layer.

What is two sedimentary rock layers separated by an erosional surface?
Disconformity
Is groundwater one word or two?
one
What is a place in the rock record where two rock units are separated by an erosional surface?
An Unconformity is an erosional or non-depositional surface that separates rocks of two different ages. This is represented by missing sediments in the stratigraphic column. If the time period represented by the missing sediments is small, the unconformity is called a diastem.
What are two main sources of pollutants that can contaminate groundwater supplies?
Sewage, nitrates from fertilizers, and phosphates all cause groundwater pollution.
What are the two zones of the groundwater?
The two zones of groundwater are the saturated zone and unsaturated zone.The saturated zone is filled with water and is below the unsaturated zone. The unsaturated zone has water and air in its pores (tiny open spaces in the soil).
What are two ways the people of Texas use groundwater?
1.) to drink 2.) to garden
Does meander help interlocking spurs form?
No. Meanders are features of the lower and middle course of a river, whereas interlocking spurs are features of the upper course, so the two do not cross. The river may weave slightly, but this is not a meander. It's more like the teeth of a zip, less curved then a meander. A meander is more a feature of deposition, and interlocking spurs are an erosional feature. But no. Meanders do not help interlocking spurs form.
What is two unusual land features in Pennsylvania?
two unusual land features in pennsylvania are two land features that are unusual or in other words deformed

How do you calculate the gradient of groundwater?
Groundwater gradient is calculated by the equation: i=dh/dl Where: i= groundwater gradient d= the change in, or Delta h= groundwater head l= length of casing in the well Using this you would take two wells, use the well log to determine the length (ie. depth) of each well, and subtract the first from the second. That's dl. On a particular date or time (must be the same time/date for both wells), you determine the groundwater elevations in the two wells and subtract the first from the second. That's dh. Divide dh by dl, the answer is your gradient. The gradient is dimensionless, if it's positive groundwater is flowing upward (vertically) in the direction of the first well to the second well, if it's negative, groundwater is flowing downward (vertically) in the direction of the first well to the second well.
