How do geologists know that the Pacific Plate is moving? How do geologists determine the age of a fault line? How do minerals occur in sedimentary rocks? What is QAL rock on geology maps? Explain how scientists date seafloor rocks.
Rocks Rock Cycle 2 Rock Classification Geologists classify rocks into three major groups depending on how they are formed: iHot Magma
i have a rock that has been chemically anaylzed, all oxides are determined. the question is asking me to determine which is qtz-normative,, olivine-norm, hypersthene-norm or nephtaline-norm. ho do i determine which one it is based on the data i am given. the ques...
How do you date a stone? To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly useradiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliab...
experienced and strain rate — or how much they deformed. In the new work, Fisher and his colleague, Greg Hirth, professor at Brown University, created a more detailed model that considers factors like the rocks’ grain size and solubility, or how much of the rock material can dissolve into...
How do scientists determine the age of fossils? To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly useradiometric dating methods, based on the natural radioactive decay of certain elements such as potassium ...
How did early geologists first develop the geological time scale? What effect does intrusion have on the geological time scale? When does the geologic time scale begin? What are the different eras in the geologic time scale? How old is Earth according to the geological time scale?
Geologists locate these deposits by prospecting -- taking core samples or drilling in soils suspected of containing the ore. By analyzing the cores, scientists are able to determine the quantity and quality of the bauxite. Luis Castaneda/Getty Images An aerial view of a bauxite mine and alumina...
This tip seems extremely important in the day and age when pretty much anything we say or do might be recorded somehow, and might show up at some surprising future moment to be displayed to a larger audience. For these reasons, it’s good advice to act and speak as kindly toward others...
“Funnily enough, many people have varieties of this type of rock as a kitchen countertop,” Dr. Smit says. “In a way, many people are preparing their dinner on the type of rock that was responsible for making our modern continents.” ...
