Which best explains the effect a tornado has on normal wind speed and direction? A. A tornado does not affect wind speed or direction. B. A tornado increases wind speed and may change its direction. C. A tornado decreases wind speed and may change its direction. D. A tornado causes wind direction to reverse and may change its speed

Which best describes how changes in air pressure can affect the development of a hurricane? A. Cooling ocean water causes air pressure to drop. This causes high winds and rain to develop, which may become a hurricane. B. Cooling ocean water causes air pressure to rise. This causes light winds and snow to develop, which may become a hurricane. C. Warming ocean water causes air pressure to rise. This causes light winds and sleet to develop, which may become a hurricane. D. Warming ocean water causes air pressure to drop. This causes high winds and thunderstorms to develop, which may become a hurricane.
