What rocks are formed by heat and pressure? Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Which type of rock does B represent? Igneous rock Which type of rock does c represent? What three minerals are most commonly found in […]
At what depth does the earth heat up?
At what depth does the earth heat up? AT a small depth (from 12 to 40 feet) below the surface of the earth the temperature is constant throughout the year, and this constant temperature of the soil differs little from the mean annual temperature of the air, except on mountains more than 6,000 feet high. […]

Why do giant squids have very thick nerve fiber?
Why do giant squids have very thick nerve fiber? Stimulation of single giant nerve fibres in the stellar nerves of the squid (Loligo pealii) shows them to be motor axons which produce contraction of the circular fibres of the mantle muscles. When a stellar nerve is stimulated with condenser discharges a maximal response is obtained […]
Is 2mg O2 2mgo balanced equation?
Is 2mg O2 2mgo balanced equation? At the same time the magnesium atoms become ions, the oxygen atoms become –2 anions by gaining one electron each. By combining these two reactions, we have an oxidation reaction and a re- duction reaction, that are perfectly balanced. Why Aluminium will not corrode in the presence of oxygen […]

Which of the following is an example of diffuse reflection? Reflection off of rough surfaces such as clothing, paper, and the asphalt roadway leads to a type of reflection known as diffuse reflection. Whether the surface is microscopically rough or smooth has a tremendous impact upon the subsequent reflection of a beam of light. What […]
How do you combine two frequencies?
How do you combine two frequencies? One way to combine two frequencies is to simply add them. This is a linear operation, and will result in just the two frequencies in the combined signal. Another way is to multiply them together. This non-linear operation results in a bunch of different frequencies being created. Can sound […]
