Geology

Geology is the study of the Earth, rocks and how they change. Geology also tries to study these features on other planets. Geology has allowed scientists to study the history of the Earth; it provided evidence that led to the discovery of plate tectonics, the discovery of the evolutionary history of life and the past climates of the Earth. Geology has many applications. These applications range from being commercially important to publicly important. The applications include mineral and hydrocarbon exploration, natural hazard predictions, remediation of environmental problems and studying climate change.

Geology also places a large focus on studying the Earth structures. Due to advances in technologies the internal composition and structure of the Earth has been found and mapped. The Earth's internal core is maintained at an extremely high temperature and pressure which has turned the rock into molten lava. Mineralogists used this data to find the elemental composition of the Earth. These breakthroughs have allowed scientists to exploit these mineral resources for commercial uses. 

Furthermore, another important concept in the study of geology is the geological time scale. This time scale is extremely important as it states the history of the Earth and has some evidence on the formation of the universe. The Earth has been found to be 4.54 billion years old. These years have been divided up into eons, eras, and periods to describe the properties of those time periods.

Plate Tectonics: Wegener's Work

Describe how Wegener's continental drift hypothesis has helped to shape modern plate tectonic theory, and why his hypothesis was not widely accepted by his peers when first proposed. Analyze the types of evidence used to support plate tectonic theory.

Radioactive dating

Compare and contrast relative age dating with radiometric dating. What are the strengths and limitations (if any) of each?

Internal vs. External Processes

Distinguish between the internal and external processes that shape the Earth's surface. For example, how are intrusive igneous rock formations different from extrusive ones and what role have those differences played in how the surface of the Earth developed and the civilization that developed on top of that?

Horizontal and Vertical Conductivity

Formation A has a thickness of 35m and a hydraulic conductivity of 7.5 m/day. Formation B has a thickness of 18m and a hydraulic conductivity of 72 m/day. Formation C has a thickness of 23m and a hydraulic conductivity of 15 m/day. Assume each individual formation is isotropic and homogeneous. calculate both the overall HOR

California's geological features and events

Describe the geological features and various types of rocks that formed in California (for example, mountains, craters, canyons, volcanoes, fault lines, or folds). Discuss the various geological events that occurred in California Describe the various types of rocks that these geological events formed.

Fossil Record Table

I need help with the following questions; In the following list, give a brief summary of what scientists have learned from the fossil record. Add one more type of evidence with a summary to the table. 1. Climate change 2. Continental drift 3. Extinct species - dinosaurs, early mammals, etc. 4. Evolution 5. Meteor

Plate Boundaries and Faults

1. The tectonic cycle is a cycle in which crust is both created and destroyed. Where does crust get created and how does this occur? Where does crust get destroyed and how does this occur? 2. Explain the three types of tectonic plate boundaries. In your explanation you must include 1) the type of boundary, 2) what is occurrin

Solution dealing with the effects of plate tectonics on climate, ancient life, and geography. How has the motion/location of the tectonic plates influenced the climate of Earth over geologic time? How does the motion of the tectonic plates affect the geography? (surface features) How does the motion of the tectonic plates affect the distribution of organisms? (current and fossil life)

Contrast the philosophies of Catastrophism and Uniformitarianism

Contrast the philosophies of Catastrophism and Uniformitarianism. What are the major differences in the how each philosophy addresses the age of the Earth? Finally, while neither philosophy should be taken too literally, which philosophy has been deemed more accurate by the scientific community and why?
