What are the 12 layers of the earth? If we subdivide the Earth based on rheology, we see the lithosphere, asthenosphere, mesosphere, outer core, and inner core. However, if we differentiate the layers based on chemical variations, we lump the layers into crust, mantle, outer core, and inner core. Which layers of earth are brittle? […]
What is the most common metalloid?
What is the most common metalloid? Silicon What are the 8 metalloids? Boron, silicon, germanium, arsenic, antimony, and tellurium are commonly recognised as metalloids. Depending on the author, one or more from selenium, polonium, or astatine are sometimes added to the list. What’s the only metalloid in Period 6? The metalloids; boron (B), silicon (Si), […]
What takes place in the reactor vessel?
What takes place in the reactor vessel? Inside the reactor vessel, the fuel rods are immersed in water which acts as both a coolant and moderator. The moderator helps slow down the neutrons produced by fission to sustain the chain reaction. The heat created by fission turns the water into steam, which spins a turbine […]
Does a rough surface reflect light?
Does a rough surface reflect light? For a rough surface, reflected light rays scatter in all directions. This is called diffuse reflection. Diffuse reflection is when light hits an object and reflects in lots of different directions. This happens when the surface is rough. Why do rough surfaces not make good mirrors? Smooth surfaces reflect […]
How do you know if a resistor is in series or parallel?
What is the correct order of the central dogma?
What is the correct order of the central dogma? How genes in DNA can provide instructions for proteins. The central dogma of molecular biology: DNA → RNA → protein. What are the steps in gene expression? The process of gene expression involves two main stages: Transcription: the production of messenger RNA (mRNA) by the enzyme […]
What happens when two pulses meet while moving through the same medium?
What happens when two pulses meet while moving through the same medium? When two pulses meet up with each other while moving through the same medium, they have a tendency to bounce off each other and return back to their origin. Constructive interference occurs when a crest meets up with another crest at a given […]
Which state wastes the most water?
Which state wastes the most water? More than one-fourth of the total water used in the United States in 2015 was withdrawn in California, Texas, Idaho, and Florida. California accounted for 9 percent of all withdrawals in the United States in 2015. What is the largest consumer of California Water? While the Golden State isn’t […]
What elements have the same properties?
What elements have the same properties? Elements in the same group of the periodic table have similar chemical properties. Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals. Groups are numbered 1–18 from left to right. Where can you find similar properties? The periodic […]
What are the three ways of conserving resources?
What are the three ways of conserving resources? Conservation means saving resources. To save natural resources, follow the three “R”s: reduce, reuse, and recycle. Why is it important to manage air and water resources wisely? In terms of human healthy, why is it important to manage air resources wisely? So we can survive and breathe […]
