<u>Answer:</u>
The Earth, as part of the solar system and the Milky Way Galaxy, is moving through this radiation and the Doppler effect produces this anisotropy.
<u>Explanation:
</u>
- The fact that the Earth is moving within a moving galaxy stands as the reason for the occurrence and non-occurrence of many phenomenons.
- The anisotropy experienced in the cosmic microwave radiation that the Earth is subject to is due to this movement of Earth.
- The positions secured by Earth during the course of its movement either block these radiations or make way for them to reach the earth, and hence, the anisotropy is experienced.
Answer: 'A' is the response.
Explanation: The diagram A appears to show a location where magma is rising as a result of an upwelling convection current in the magma, which could cause the sea bottom to spread. The spreading of the crust is indicated by the arrows. This will become a focal point for the spreading marine floor.
