Answer:
No
Explanation:
Crystizaltion of magma turns into indeginous rocks which then turns into sediment after weathering and erosion.
Answer:
The equatiom of kinetic energy is 1/2×m×v² where m represents mass and v is velocity :
The unit for kinetic energy is measured in Joules (J).
Answer:
Material medium
compressions and rarefactions
Explanation:
A sound wave is an example of a mechanical wave. All mechanical waves require a material medium for propagation. The medium for the propagation of sound is air. This is the reason why, if you cover your mouth, it will be difficult for another person to hear whatever you are saying.
Sound is also a longitudinal wave. Longitudinal waves are described in terms of compressions and rarefactions. Compressions refer to areas where air molecules crowd together while rarefactions refer to areas where the air molecules spread out.
