Which best explains how the collisions of materials in space contribute to the formation of layers in protoplanets?
Sedbober [7]

Answer:The best explanation is;

The materials undergo decay when they collide, which results in the heating and subsequent melting and rising of materials

Explanation: A protoplanet is an embryo formed in a protoplanetary disc which has passed through a melting phase that enables the formation layered interior

In protoplanets the effects of partial melting of the components due to heating produced by radioactive decay and  pressures from forces of gravity there is segregation of the melt and igneous composition such that the heavier melted metal can sink and be over laid by the lighter igneous rocks

Therefore, the best explanation is that the materials undergo decay when they collide, which results in the heating and subsequent melting and segregation by the sinking of the heavier melted materials and rising of the lighter igneous materials.

What does this same experiment tell you about light waves?
lianna [129]

Answer:

For any experiment we can say that light waves are the electromagnetic waves because they make up what is known as the electromagnetic spectrum.

Explanation:

  • Light is the moving energy form that is made up of tiny particles known as photons.
  • The light waves comprises of both magnetic and electric aspects hence known as electromagnetic.
  • The process of propagation of light wave is : the fields vibrates perpendicularly in the same direction of propagation of the wave, and at 90 degree angle with each other.
  • Similar to sound waves, light wave can interfere with each other.
