Answer: It is the result of a mixture of radiation from many independent sources, such as stars and galaxies.
Microwave background radiation is a form of electromagnetic radiation that is present in the whole universe and completely fills it. In fact, it is the leftover radiation from the Big Bang that occurred 400,000 years before the events related to this cosmic radiation.
Its frequency belongs to the microwaves range and is one of the main demonstrations of the of the Big Bang theory model.
The process of erosion or the wearing away of soil and rock will most likely causing people to move from coastal cliffs. Many coastal cliffs have been worn away by this process and houses and roads are in danger of being destroyed by this process.
At the point when the measure of the surface region with respect to volume builds, the rate of weathering increments. Weathering is the breakdown of rocks at the Earth's surface, by the activity of water, extremes of temperature, and natural action. It doesn't include the expulsion of shake material.
The most likely answer is A) Geothermal
