Geology Definition and 73 Threads

I am interested in a easy-to-read book on global geology and/or climate. The book will be ideal if it has discussions on how geology and climate changes, with detailed graphs (or data), due to seismic activities, external impacts like the solar wind from the Sun, and human-induced...

Has anybody heard of this odd sub-type of physics and geology? Apparently Tesla was able to build devices that could create earthquakes with his technology. I want to know what these sorts of equations looked like if anybody knew.

I am currently in my third year of my geology degree which I am enjoying but I love physics too. I don't really want to be strictly a geologist after I graduate, more like a geophysicist as I've taken an interest in seismology after narrowly surviving the 2011 Christchurch quake while in New...

Recently I went trekking in the Northern areas of pakistan. More specifically the gojal district, very near the afghan border. I found these samples and wondering what they actually were. there is a a lot of folklore behind these samples as well. They say thousands of years ago there lived a...

Homework Statement (Picture attached) How does the process of sea-floor spreading produce these orientations and relationships [between the ages of magnetic stripes and the distance from the ridge crests, as well as the parallel direction of the magnetic stripes with those of the ridge...

anyone who has majored in geology, please give tips, advice, warnings, pros, cons

Do you think it would be beneficial for me to add Geology to my Astrophysics B.S? I know it's going to be a bit tough for you to answer this questions without me knowing exactly what career I want to pursue (which I don't) but I have a general idea. I'm really interested in studying the...

Homework Statement My geology profesor gave us 50 questions to practice and check our progress. I have manged to answer all of them but two: Why would you study a volcanic rock in a sedimentary succession where oil is found? You work in an area where your sedimentary rock is host to...

I'm looking for Principle of Geology by Charles Lyell. Wikipedia says it was released in 3 volumes, but all I can find online is this: https://www.amazon.com/dp/014043528X/?tag=pfamazon01-20 Is that just volume 1? Is it all 3 volumes? Has anyone bought this book before?

I want to take either a geology or physical geography class; I don't know which one I would enjoy more. If I take geology, it fulfills a prerequisite for another class I would like to take, Speleology; but the likelihood of me taking this class is unlikely. I have a general idea of the...

We got on the subject of types of rocks, some formed by the carcasses of marine animals on the sea floor. When organisms die, the body is chemically and physically broken down and the composing elememts and compounds are reintroduced into the Earth's natural cycles. Eg all of the organism is...

(I moved this from the Homework section. I hope it is okay I am posting here.) Homework Statement We are given six cross sections each spaced 2km apart and from these we are supposed measure the slip of the fault, and map the hanging-wall and footwall cutoffs to another worksheet that is...

I am a senior in college and want to work in the field of energy, either oil or nuclear. I was wondering what the best major would be? I was thinking oceanography, geology or physics. I was thinking oceanography because I want to work with the ocean in someway, how can I do this? How is the...

Hi, I am trying to find out about lunar rocks, the ones that came back from apollo. Moon landing hoaxers debunk the whole thing but in my mind, it seems unanswerable the idea that in the 60's and 70's we could have faked the moon rocks brought back. So, I am trying to see if I can close that...

'The first age, the Phyllocian era, lasted from just after the planet's birth to about four billion years ago. Ancient rocks show the presence of clay-rich minerals - phyllosilicates - which to form would have required a water-abundant alkaline environment. Volcanoes erupt The second era...

Hello, I'm currently living in Canada and about to enter University, I'm wondering about if I should consider going into this. I was wondering if someone could give me some help and tell me what the industry is like and if there are future job possiblities. Also wondering how much they...

I am looking for good information about the formation of earthquakes. My textbook is not very good and Wikipedia did not satisfy me. I know that someome might have a good site or article about this topic. Thank you. I will continue to search, if i find one I will warn you. Thank you! :biggrin:

As you know wi-fi is a radio signal and I'm wondering if physics can help me by determining why is my internet acting weird on me. I know about waves and nodes and antinodes and I'm wondering does wi-fi have these properties and how can i position it. In a geological perspective its distance...

... asked what to study if he wanted to investigate creationism versus evolution. I advised continuing physics and chemistry and avoid having to learn flawed theories as paradigms. So, predictably, I was challenged to expose some of them. I choose for the problems in the 100,000 "ice age" cycle...

http://www.lunarrepublic.com/news/media_love_021302.shtml The Moon's surface, pulled by the Sun and Earth, may bulge out and dip in as much as 10 centimeters (almost four inches) over 27 days. Love numbers show how elastic the Moon is, giving clues to the material under the surface. The newly...
