Answer to Question 1

Answer: If we look at the height of some given pressure level (such as the 500 mb level) on a map, its height will often vary from one place to another. More specifically, the surface will slope downward in the direction of colder air, because cold dense air has stronger vertical pressure gradients and will attain a particular air pressure at a lower height (assuming for simplicity's sake that sea-level pressure is uniform). Where a horizontal pressure gradient exists, there must also be a slope in the height of a particular pressure level, with heights decreasing toward colder air.

Answer to Question 2

Answer: Coriolis force (effect)
