Describe each of the following and explain how it contributed to our current acceptance of plate tectonic theory: Paleomagnetism Seafloor Spreading Divergent Plate Boundaries Transform Plate Boundaries Convergent Plate Boundaries
What are some nautural causes and effects of sand deposition? What are some geological features that can develop from sand deposition over time?
In this question you will be drawing a section of a cliff that comprises three rock types A,B,C. A geologist sees a cliff where rock C forms the lower half of a cliff, and is immediately overlain by a sandstone (rock B) comprising well rounded grains with finely pitted surfaces. the sandstone reaches to the top of the cliff. In
If gabbro cuts across both sandstone and schist and schist is the oldest, draw a geological cross section showing relations between the rocks. Write about the geological history of the region starting with the oldest events.
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? (Hint: Think of fossils, tectonic setting, etc.)
Discuss the distribution of seafloor sediments in the ocean basins. What are the different types of sediments and what are the factors that control their distribution (geologic setting, climate, etc.)?
Discuss the importance of wind as an agent of erosion and explain why such statements are probably geologically inaccurate.
Wind is included along with gravity, water, and ice as an agent of erosion. In many national parks and other areas of natural beauty, statements are often made that credit wind as having sculpted the landscape. Discuss the importance of wind as an agent of erosion and explain why such statements are probably geologically inaccur
Compare and discuss those stream characteristics that decrease in a downstream direction with those that increase downstream.
Compare and discuss those stream characteristics that decrease in a downstream direction with those that increase downstream. Also, indicate and discuss whether these changing stream characteristics tend to favor erosion or deposition of sediments.
Considering the various processes involved in mechanical and chemical weathering, what are some of the factors that influence or control the weathering of earth materials?
Considering the various processes involved in mechanical and chemical weathering, what are some of the factors that influence or control the weathering of earth materials? Also, discuss which of these factors would be most important and why?
Develop a qualitative understanding for the effects of the tilt of Earth's rotation axis on the length of days and solar radiation received throughout the year.
Develop a qualitative understanding for the effects of the tilt of Earth's rotation axis on the length of days and solar radiation received throughout the year. See attached file for full problem description.
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.
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.)
What is the formula to calculate the age of a moon rock sample? For example, how would I calculate the age of a moon rock sample knowing the number of grams of potassium-40 and argon-40 with a given half-life in a closed system assuming no argon-40 was present when the rock was formed?
Stages in mountain belt formation. Investigate two mountain belts (or ranges) which have features that are distinctly different from each other.
Mountain Belt Formation Complete sections A and B of this appendix. A. Briefly describe each feature associated with mountain belts. Characteristics How it is related to mountain belt formation accumulation stage orogenic stage uplift stage block faulting erosion magm

If a lab reports there are the same number of daughter as parent atoms, the number of half-lives elapsed are 1,2,3, or 4?
Both of this mountain are mountain belts - one is a folded mountain belt the other is a Igneous mountain belt. I need to know more facts about this two mountains. What make them alike and what make them different.
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
I am not sure if I did the following 3 questions properly (please see attached file). Can you please check them?
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,
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
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
Discuss the steps of the scientific method and how Wegener used the scientific method in theory development. Can you explain how the theory of plate tectonics, as proposed by Wegener, was developed following the scientific method?
For study purposes, can you provide me with a glossary of volcanic and geologic terms with definitions provided?
