Geology

Atmospheric circulation

Considering the theory of plate tectonics and the movement of landmasses over geologic time, would you expect atmospheric circulation of the past to be the same as we see today? Why or why not? Consider the factors that determine global wind patterns and whether they have changed over time.

Determining movement of a fault.

A fault is observed in a road cut, but there are no obvious rocks units to correlate on either side of the fault to determine relative movement. How else might you determine or even infer whether the hanging wall has moved up or down relative to the footwall? (Think of fossils, tectonic setting, etc.)

Earth Science: Forces Within the Earth

I need your assistance in putting together a response to the following earth science question: How do forces within the earth especially in the Lithosphere, asthenosphere, and Mesosphere determine and /or cause earthquakes, volcanoes, tidal waves, faults, fold fractures, continental plate movement and rock formation? Please

Strata dating using relative dating methods

The question was about four rocks Granite, Slate, Limestone and Shale or Mudstone. For example, the field setting of rocks is as follows: On the bottom is what I think to be a pluton of granite either side is slate, on top of slate is limestone, and on top of limestone is Shale or Mudstone. In the field setting of the above,

Dating methods to place events

I have four rocks Granite, Slate Limestone, and Shale or Mudstone. Field setting of the rocks is as follows: On the bottom is Granite either side of the granite is Slate, on top of Slate is Limestone, the top layer is Shale or Mudstone In the field setting of the above rocks there is a selection of of possible events in the

Hydrogeology Fetters (average linear velocity)

9. A confined aquifer is 8 ft thick. The potentiometric surface drops 1.33 ft between two wells that are 685 ft apart. The hydraulic conductivity is 251 ft/day and the effective porosity is 0.27. (A)How many cubic feet per day are moving through a strip of the aquifer that is 10 ft wide? Show all work. (B)What is the average l
