Based on the information provided in the question, the most likely result if a high-pressure system remains in an area for a long period of time is: A - fog. High-pressure systems are characterized by a clockwise rotation of air masses in the atmosphere, which can lead to a stable and dry atmosphere. As a result, fog is more likely to form in the area as the air is unable to rise and cool, causing the water vapor to conden

The answer is (B) Earth rotates around the sun. The statement "The sun appears to move across the sky each day" suggests that the sun is moving relative to the observer's position on Earth, rather than the other way around. This is because Earth is rotating on its axis, causing the sun to appear to rise and set in the sky. The sun does not revolve around Earth, as stated in option (A), nor does it revolve on its axis
