What is the role of heat and pressure to metamorphism? Metamorphism occurs because some minerals are stable only under certain conditions of pressure and temperature. When pressure and temperature change, chemical reactions occur to cause the minerals in the rock to change to an assemblage that is stable at the new pressure and temperature conditions. […]
Can Methanol be broken down by a chemical change?
Can Methanol be broken down by a chemical change? Which substance can be decomposed by a chemical change? Reason: when it said a substance, think of the matter chart. Substances can be broken down to a compounds or elements. Beryllium, Boron, and Magnesium are elements and Methanol is a compound which can be chemically change. […]
Who is the father of LED bulb?
Who is the father of LED bulb? Nick Holonyak Who invented the first LED light? Shuji Nakamura What purpose do LED lights serve? LED stands for light emitting diode. LED lighting products produce light up to 90% more efficiently than incandescent light bulbs. How do they work? An electrical current passes through a microchip, which […]
What happens if u eat chalk?
What happens if u eat chalk? Chalk is considered non-toxic in small amounts. If large amounts are eaten, it can be irritating to the stomach and cause vomiting. Chalk can be a choking hazard for very young children. CAUTION: Eating pool or billiard chalk can be different than school and blackboard chalk because it may […]
What would happen if solar winds hit Earth?
What would happen if solar winds hit Earth? The most powerful solar storms send coronal mass ejections (CMEs), containing charged particles, into space. If Earth happens to be in the path of a CME, the charged particles can slam into our atmosphere, disrupt satellites in orbit and even cause them to fail, and bathe high-flying […]
What color of light has the highest frequency?
What color of light has the highest frequency? Violet waves What is the depression of light? Dispersion of light is caused by the change of speed of light ray (resulting in angle of deviation) of each wavelength by a different amount. Note: White light comprises of seven visible colours (VIBGYOR) whereas black (or dark) signifies […]
How many types of erosion are there?
How many types of erosion are there? Like water erosion, there are three different types of wind erosion, surface creep, saltation, and suspension. What is called erosion Class 6? The wearing away of the earth’s surface is called erosion. Explanation: Erosion is the phenomenon of the removal of the top layer of the Earth’s surface […]
What would happen if a gamma ray hit Earth?
What would happen if a gamma ray hit Earth? With the gamma-rays beamed directly at Earth, the radiation would destroy a significant portion of our atmosphere, specifically the ozone layer. The photons streaming from the burst would cause chemical reactions leading to photochemical smog. This would further deplete our protection from cosmic rays. How far […]
What are the four principles of stratigraphy?
What are the four principles of stratigraphy? Steno’s laws of stratigraphy describe the patterns in which rock layers are deposited. The four laws are the law of superposition, law of original horizontality, law of cross-cutting relationships, and law of lateral continuity. Nicolaus Steno was a 17th-century Danish geologist. Which kind of unconformity is probably the […]
What are the three roles of bacteria?
What are the three roles of bacteria? In summary, bacteria are single-celled microbes without a nucleus. Bacteria play many roles in our ecosystem. Bacteria are decomposers which break down dead material and recycle it. They also can be producers, making food from sunlight, such as photosynthetic bacteria, or chemicals, such as chemosynthetic bacteria. What are […]
