Does speed of sound depend on pitch? The speed of sound is dependent on temperature. As the temperature of the air increases, the speed of sound in air increases. Frequency of sound and pitch are related. The higher the pitch, the greater the frequency. What is the highest possible frequency of sound? That’s about the […]

Can plate tectonics be proven?
Can plate tectonics be proven? What is the cause of plate tectonics? Although this has yet to be proven with certainty, most geologists and geophysicists agree that plate movement is caused by the convection (that is, heat transfer resulting from the movement of a heated fluid) of magma in Earth’s interior. What are the evidences […]
How often does the jet stream shift?
How often does the jet stream shift? This movement creates an air current, or wind. A jet stream is a type of air current that forms high in the atmosphere. On average, jet streams move at about 110 miles per hour. Why do waters sink in the North Atlantic? Water flowing northward becomes modified through […]
