The important thing to know about the following dataset.

The magnetic anomalies are a mirror image on either side of the ridge, implying that the entire ocean floor was created at the ridge and subsequently moved outward from it in either direction
A rapidly rotating column of air often spawned by a supercell thunderstorm
What are tornadoes?
The type of hazard responsible for the damage shown

What is tephra fallout?
The explosivity of an igneous rock with abundant pink and light colored minerals
What is high explosivity?
The phenomenon, due to the rotation of the Earth, that makes objects moving north or south appear to deflect from their course
What is the Coriolis effect?
The graph that indicates tornado formation is possible.

What is A: The air is warm and near the dew point (holding almost all the moisture it can possible hold) and there is a temperature inversion (of dry air) that will suppress this air from rising until it is even warmer and wetter.
