1. Which of the following is a correct description of a tornado? (1 point)
O a large swirling, low-pressure system that forms over the warm Atlantic Ocean
O a winter storm with wind speeds of at least 56 km/h and low visibility
O a violently rotating column of air in contact with the ground
O a boundary between two air masses of different density, moisture, or temperature

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 because tornadoes are columns of air that rotate due to warm air and cold air colliding. 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.

the thirteen colonies are:

tension is the type of stress that results when two tectonic plates diverge .
