Answer 1

Answer: D) A high pressure system turned into a low pressure system.

Explanation:

In barometer reading, a falling hand on a barometer indicates a low pressure system is on the way with poor weather (usually a storm with snow or rain); a steady barometer means there will be no changes with the ongoing pressure system; and a rising barometer means high pressure and fair weather.
