Question

Q1 Can wind travel faster than the speed of sound

Q2 How does Earth's interior work, and how does it affect the surface?

Q3 Does the back of a rainbow look the same as its front side​

Answer 1

Answer:

1.Yes, wind can travel faster than the speed of sound. Wind is just the bulk movement of a mass of air through space and is in principle no different from a train speeding along or a comet zipping through space.The speed of sound just describes how fast a mechanical wave travels through a material.

2.Water forms some features of Earth's surface such as rivers, oceans, beaches and lakes. Other surface features, such as mountains, earthquakes and volcanoes, are formed when large pieces of the Earth's outer layer move slowly by plate tectonics.

3.A rainbow does not have a back side. The sun is always in the opposite part of the sky from the center of the rainbow. This is because a rainbow is actually just sunlight which has been refracted and reflected.
