Which rocks contain the most silica? Compilations of many rock analyses show that rhyolite and granite are felsic, with an average silica content of about 72 percent; syenite, diorite, and monzonite are intermediate, with an average silica content of 59 percent; gabbro and basalt are mafic, with an average silica content of 48 percent; and […]
Which region has many mountain ranges separated by desert basins?
Which region has many mountain ranges separated by desert basins? Great Basin physiographic section The Basin and Range region is the product of geological forces stretching the earth’s crust, creating many north–south trending mountain ranges. These ranges are separated by flat valleys or basins. These hundreds of ranges make Nevada the most mountainous state in […]
Does &= short circuit?
Do longer wavelengths have low energy?
Do longer wavelengths have low energy? Related to the energy and frequency is the wavelength, or the distance between corresponding points on subsequent waves. Shorter waves move faster and have more energy, and longer waves travel more slowly and have less energy. Why do short waves have high energy? “Short wavelength” is the same as […]
What are the 10 thinking errors?
What are the 10 thinking errors? The most common thinking errors can be divided into these 10 categories, which are adapted from David Burns’s book, Feeling Good: The New Mood Therapy . All-or-Nothing Thinking. Overgeneralizing. Filtering Out the Positive. Mind-Reading. Catastrophizing. Emotional Reasoning. Labeling. Fortune-telling. How can I change my mind from negative to positive? […]
Can we prove axioms?
Can we prove axioms? Unfortunately you can’t prove something using nothing. You need at least a few building blocks to start with, and these are called Axioms. Mathematicians assume that axioms are true without being able to prove them. If there are too few axioms, you can prove very little and mathematics would not be […]
What are the advantages of interdisciplinary studies?
What are the advantages of interdisciplinary studies? Interdisciplinary programs draw from two or more academic disciplines that work together to create a powerful learning experience and emphasize integrative learning, critical thinking, and creative problem solving. What is the main aim of interdisciplinary research? 20) What is the main aim of interdisciplinary research? Explanation: Particularly in […]
What happens to the force of attraction when?
What happens to the force of attraction when? Hence force of attraction will be quadrupled. (1) When distance between objects is doubled, force of attraction will become 122=14 times i.e. will become one-fourth. (3) When distance between objects is halved, force of attraction will become 1(12)2=114=4 times i.e. will become four times. How many G’s […]
How do you describe a distance time graph?
How do you describe a distance time graph? If an object moves along a straight line, the distance travelled can be represented by a distance-time graph. In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the […]
What are the 4 ways to manage risk?
What are the 4 ways to manage risk? Once risks have been identified and assessed, all techniques to manage the risk fall into one or more of these four major categories: Avoidance (eliminate, withdraw from or not become involved) Reduction (optimize – mitigate) Sharing (transfer – outsource or insure) Retention (accept and budget) What is […]
