TRUE, a cold front is defined as  leading edge of a mass of cooler air that is pushing warmer air ahead of it out of the way.

4.If you see a tornado and it is not moving to the right or to the left relative to trees or power poles in the distance, it may be moving towards you.

TRUE , The tornado may either move towards you or away from you. A tornado always keeps moving until stability of air mass is achieved, Once stability is achieved the tornado dies out.

.5.A cold front is defined as the transition zone where a warm air mass is replacing a cold air mass.

FALSE, a cold front is defined as  leading edge of a mass of cooler air that is pushing warmer air ahead of it out of the way. i.e cold front is transition zone where a cool air mass is replacing a warm air mass
