Answer:

Mantle convection is the very slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface. The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle.

Define each of the following wave phenomena, and give an example of where each occurs: (a) refraction;
Svetach [21]

Refraction is the phenomenon of change in the speed of light when the light when passes from the medium of one optical density to a medium of another optical density. The light rays also show a bending when passing through the interface of such a medium.

<h3>What causes wave refraction?</h3>

Refraction is the bending of waves due to a change in speed as they travel through different media. Waves may accelerate or decelerate when they go obliquely from one medium to another. The waves will bend more dramatically as their speed changes.

<h3>What characteristics does a wave have?</h3>

The following characteristics of waves:

  • Refraction is the bending of waves as they move from one medium to another due to a change in their speed.
  • Waves may speed up or slow down as they transition from one medium to another at an angle.
