Hello :)
External migration is D. Moving from one country to another
Hope this helps
Answer:
Option (1)
Explanation:
The moon is the natural satellite of earth. It revolves round the earth once every 27.3 days. The sun is located at a distance of nearly 93 million miles away from the earth. Whereas the moon is at 239000 miles away from the earth. But, both the moon and the sun roughly appears to be of the same size when viewed from the sun. The orbit of the moon around the earth is getting larger, that is enhancing at a rate of approximately 3.83 centimeters every year. The reason behind the increase in the moon's orbit is because of the tides on the Earth. This tidal generates a force, known as the tidal force, that acts as a strong gravitational pull. The earth's side that faces the Moon is the closest. The earth always faces the same side of the moon.
Hence, the correct answer is option (1).
Low pressure areas are 970 and 1,010.
Explanation:
The air pressure represents the pressure that the air makes with its wight on the objects. Basically, the heavier the air is, the higher the air pressure is, and the lighter the air is, the lower the air pressure is. The air pressure is measured in mbar, hPa, and Pa.
Standard air pressure conditions are considered to be 1,1013.25 mbar. Every value that is larger than this one means that the air pressure is high, and every value below this one means that the air pressure is low. In this case, the only two values that are below the standard value of the air pressure are 970 and 1,010, thus making them the only two values with low air pressure.
The air pressure is influenced by multiple factors:
- temperature
- precipitation
- elevation
Some facts about the air pressure are:
- the colder the air is, the higher the air pressure is
- the warmer the air is, the lower the air pressure
- the air pressure is higher closer to the surface of the Earth, and it gets lower with elevation
- the precipitation increases the air pressure

Answer:
claimed that ice at the poles does not melt in a gradual and linear fashion, but that another according to the geological record, the ice sheets can suddenly destabilize when a certain threshold is exceeded. Sea level rise due to the collapse of an ice sheet would be distributed non-uniformly across the globe.
