Answer: B. International migration and voluntary migration: Family A from Mumbai has convinced their close friends Family B to emigrate to London as they did in order to help start up their business.
Explanation:
Migration is the process of moving from the place of origin to another area due to personal, social or political reasons. Throughout human history, we have migrated for various reasons, from searching for food, from safer areas to live or exploring new territories, it is part of our nature.
Currently, migration is classified as voluntary or forced migration and internal or international migration.
- Voluntary migration consists of voluntary internal or international displacement, permanent or temporary, to seek better economic opportunities.
- Forced migration occurs when the displacement is carried out against the will, due to situations of violence, natural disaster or eviction.
- Internal migration is what occurs within the same territory, for example from rural to urban areas.
- International migration consists of movements from the country of origin to another country.
In this case, Family A convinces Family B to make an international migration (from India to England) voluntarily (To establish a business).

Answer:
<u>Geocentric Model</u>: - this model is Earth Centered
-Retrograde motion is explained by epicycles
<u>Heliocentric Model</u>: - This model is Sun Centered
-Retrograde motion is explained by the orbital speeds of planets
<u>Both models</u>:- Epicycles and deferents help explain planetary motion
-Planets move in circular orbits and with uniform motion
-The brightness of a planet increases when the planet is closest to Earth
Explanation:
Retrograde motion is an apparent change in the movement of the planet through the sky. Ptolemy's model of the solar systems was geocentric, where the Sun, Moon, planets and start all orbit the Earth in perfectly circular orbits. However this perfectly circular orbits around the Earth did not explain the occasional retrograde motion of the planets. In the Copernicus' heliocentric model, retrograde motion of planets is naturally explained. The explanation for retrograde motion in a heliocentric model is that retrograde occurs roughly when a faster moving planet catches up to and passes a slower moving planet.
