When an earthquake wave passes from the crust to the mantle, the wave
A. stops moving.
B. reverses direction.
C. increases energy.
D. changes speed.

Answers

Answer 1

Answer:

Hey!

Your answer is that the wave CHANGES SPEED

Explanation:

Because of the different mediums, the earthquake waves (P-Waves and S-Waves) will get REFRACTED. REFRACTION happens when the wave SLOWS DOWN because it is moving from an area of LOWER density to an area of HIGHER density...

(OR IT COULD BE THE OTHER WAY ROUND!!)

...slowing down because there are more particles in the way preventing it from "moving" (transferring energy etc)…

I HOPE THIS HELPED YOU!
Answer 2

When an earthquake wave passes from the crust to the mantle, it undergoes a change in its speed, as the seismic waves travel at different velocities through different layers of the Earth.  Hence option D is correct .

What happen when an earthquake wave passes from the crust to the mantle ?

The mantle is located below the crust and is made up of denser, more solid rock, which causes the seismic waves to move faster compared to the crust.

The speed of an earthquake wave depends on the density and elasticity of the material it passes through. The mantle is denser and more rigid than the crust, causing the seismic waves to travel faster in the mantle.

Therefore, when an earthquake wave passes from the crust to the mantle, it increases its speed and continues to propagate through the Earth's interior.

The movement of an earthquake wave is caused by the release of energy stored in rocks that have been subjected to stress. As the seismic waves travel through the Earth's layers, their energy is dissipated through friction and heat, causing them to gradually weaken.

In summary, when an earthquake wave passes from the crust to the mantle, it changes speed due to the different density and elasticity of the material it passes through. The wave does not stop moving, reverse direction or increase energy.

Explanation:

Cultural Isolation occurs when a group of people values their culture so much that they find it difficult to learn the culture of others. Africans and Asians had cultural values, beliefs, and practices that they held dear. But in recent times that has been declining because of the advent of technology which has exposed these groups of people to Western ways of doing things.

They seem to get so carried away by these foreign cultures such that they neglect their own customs. They adopt Western ways of dressing, religion, beliefs, etc., and in doing so, they relegate their cultures to the background.

The trade winds, prevailing westerlies, and polar easterlies are the three dominant wind belts connected to these cells (Fig. 3.10). Only the circulation cells and winds in the Northern Hemisphere are depicted in Fig. 3.10.

The crews of sailing ships that relied on the winds during westward ocean journeys gave the trade winds their names.

Trade wind, a steady wind that originates in the intertropical convergence zone and flows from subtropical high-pressure bands westward and toward the Equator (ITCZ). Over the oceans, it is stronger and more reliable than over land, and it frequently results in onlyClear skies that make trade-wind islands famous tourist destinations or gloomy skies distinguished by thin cumulus clouds.
