Which process contributes to the formation of tornados? a. water droplets freeze, giving off energy b. the storm begins to rotate around a central eye c. warm air rises, resulting in a decrease in air pressure. d. a cold, dry air mass interacts with a warm, moist air mass

D. A cold, dry air mass interacts with a warm, moist air mass.

Step-by-step explanation:

Tornadoes are very scary and kind of cool to look at. They have a great scientific reason behind them which we can easily understand.  First, a funnel cloud forms that reaches down to the ground (you probably have seen this in video as a cloud that is heavily densed and circling). Then , warm air rises, resulting in a decrease in air pressure and finally, a cold, dry air mass interacts with a warm, moist air mass.

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
