Why should mass not be represented by an arrow? But, we should also remember that mass is a scalar quantity which says that mass does not have any directions. It is just the amount of matter contained in any objects. So, there is no need to represent mass by an arrow. It is a simple […]
Why is it called Bicarb?
Why is it called Bicarb? 1 Answer.

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.

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 […]
