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? […]
How did Piaget and Vygotsky view the path of cognitive development?
How did Piaget and Vygotsky view the path of cognitive development? Vygotsky believed that the child is a social being, and cognitive development is led by social interactions. Piaget, on the other hand, felt that the child was more independent and that development was guided by self-centered, focused activities. What is the correct order of […]
Which is the best example of physical or mechanical weathering?
Which is the best example of physical or mechanical weathering? Examples of mechanical weathering include frost and salt wedging, unloading and exfoliation, water and wind abrasion, impacts and collisions, and biological actions. All of these processes break rocks into smaller pieces without changing the physical composition of the rock. Which event is an example of […]
Is light or dark wood floors better?
Is light or dark wood floors better? There will be a higher chance of scratches and scrapes, which light hardwood can hide better than dark hardwood. While you’re free to mix and match styles, many homeowners find that darker hardwood flooring lends itself to a more rustic design, while lighter wood is used to create […]
Will you say a body is in uniform acceleration?
How do you know if a resistor is in series or parallel?
Which is more permeable silt or sand?
Which is more permeable silt or sand? For example, a sandy soil will have larger porosity than silty sand, because the silt will fill in the gaps between the sand particles. But it would a lower permeability because the water would have a “harder” time getting through because there would be less space for it […]
What happens when a wave goes around a barrier?
What happens when a wave goes around a barrier? Diffraction: A wave encountering a small obstacle tends to bend around the obstacle. This bending of the wavefront is called diffraction. When a wave encounters a barrier with an aperture, which is much smaller than the wavelength, the wave bends and spreads out as a spherical […]
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 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 […]
