Option A, "a large swirling, low-pressure system that forms over the warm Atlantic Ocean" is incorrect because tornadoes do not form over water. That would be a hurricane.
Option B, "a winter storm with wind speeds of at least 56 km/h and low visibility" Is incorrect because tornadoes do not form in cold weather. That would be a blizzard.
Oa boundary between two air masses of different density, moisture, or temperatureption C, "a violently rotating column of air in contact with the ground" is correct <u>because tornadoes are columns of air that rotate due to warm air and cold air colliding.</u> They usually occur during a thunderstorm.
Option D, "a boundary between two air masses of different density, moisture, or temperature" is incorrect because tornadoes are not based on air mass, density, moisture, or temperature. This would be a front.
Answer: The earth layers and atmospheric layers are distinctly different.
Explanation:
The earth layers are made up of solid matter whereas the atmospheric layers are made up of gases.
The earth layers provide the base for the survival of diversity of living beings whereas the atmospheric layers only allow microbes which can survive in extreme temperature conditions.
The stratospheric layer of the atmosphere protects the living beings from the harmful radiations striking on the surface of earth and they are capable of causing mutation whereas the lithosphere or any other surface layer of the earth also absorb thermal energy from sun but does not provide protection against harmful affects of ultraviolet radiations.
