This is true (assuming this is a true or false question)
Answer:
Advection refers to the transport or movement of the substance or objects along with the bulk motion of the fluid. It is caused due to the velocity of the fluid.
Whereas, convection refers to the transfer of heat due to the movement of the molecules of liquids and gases in bulk. It is caused due to the density gradients produced by the thermal gradients.
Answer:
At the boundary with the core.
Explanation:
The mantle is the second layer from the top. It is bordered by the lithosphere above it, or rather by the crust, and by the outer core below it. The mantle is a layer which is in viscous state, being mostly consisted of molten metals and rocks. The temperature of this layer is not the same all throughout it, but it varies a lot. The temperature at its top part is around 200 C degrees, while the temperature at its bottom is around 4,000 C degrees. There's two reasons for this. One is that the core is very hot, so it makes the bottom part of the mantle very hot as well, and the other one is that the lithosphere is much cooler, as well as constantly getting new, cold, crust in it, which makes its top part much cooler. The mantle is the layer responsible for the movement of the tectonic plates on the surface, as it is the layer where the convection currents occur and drive the plates' movement.
Answer:
This is True
Explanation:
Wave is a disturbance or the transition of vibrating energy from one point to another. The wavelength of a wave is the distance between the vibrating peak or the crest of the wave. It is the ratio of wave velocity and frequency.
Rough and dull surfaces tend to absorb wave radiation better than shiny and reflective surfaces. The diffusion, reflection and refraction of radiation also depend on the wavelength of the wave or radiation. For example, water absorbs radiation with long wavelengths than waves with short wavelength.
