How do I identify an alluvial fan? Check the mouths of tributaries in larger valleys while in the field. Check topographic maps, and look for fan shaped elevation lines at the mouths of tributaries. Check soils maps for soils designated as “local alluvium.” What is the human impact of alluvial fan? Willful and continuous interference […]
How do we use infrared waves in everyday life?
How do we use infrared waves in everyday life? Infrared (IR) light is used by electrical heaters, cookers for cooking food, short-range communications like remote controls, optical fibres, security systems and thermal imaging cameras which detect people in the dark. The heating effect of IR can cause burns to the skin. Can deer see IR […]
What are the biggest causes of water pollution?

Agriculture represents one of the biggest sources of water pollution in the country. Runoff and Nonpoint Source Pollution. Industrial Activities. Leakage from Underground Storage and Piping. Leaking Sewers. Vehicle Emissions. Landfill Leakage. Hazardous Waste. […]
What is the difference between model and approach?
What is the difference between model and approach? As nouns the difference between model and approach is that model is a person who serves as a subject for artwork or fashion, usually in the medium of photography but also for painting or drawing while approach is the act of drawing near; a coming or advancing […]
Why are top predators so rare?
Why are top predators so rare? This energy constraint is the fundamental reason top predators are so rare. Many food webs consist of half a dozen or more trophic levels, and by the time you get to the top, there’s simply not that much energy left. It’s their naturally small populations that also leave these […]
What happens to pressure if volume decreases in gas?
What happens to pressure if volume decreases in gas? Explanation: Gas particles exert pressure by colliding with the walls of their container. If you reduce the volume, you are effectively increasing the density of the particles and they will collide with the walls more frequently, leading to an increase in pressure. Why does the volume […]
What is the coating on the inside of a light bulb?
What is the coating on the inside of a light bulb? The white powder coating inside the glass tubing of a CFL contains a fluorescent coating. When electricity enters a CFL, mercury and argon fumes inside the bulb produce invisible ultraviolet (UV) light. This UV light reacts with the fluorescent coating to produce the white, […]
Is deceleration a physics word?
Is deceleration a physics word? Rick suggests: “Deceleration” is not actually a term in physics. It is only an English word used in common speech, meaning “a decrease in speed.” The problem with this word is that some students mistake it to mean the same as negative acceleration. Is deceleration a vector quantity? In a […]
What does a horizontal line indicate?
What does a horizontal line indicate? A horizontal line is commonly used in technical analysis to mark areas of support or resistance. A horizontal line runs parallel to the x-axis. In technical analysis, the horizontal line is typically drawn along a swing high, or a series of them, where each high in the series stopped […]
What is the ideal gas thermometer?
What is the ideal gas thermometer? In principle, we can measure the same temperature using any gas, so long as the constant operating pressure is low enough. When we do so, our device is called the ideal gas thermometer. The (very nearly) direct proportionality of two low-pressure real gas volumes contrasts with what we observe […]
