🔍 Key Concepts

• Buys Ballot's Law and how it relates wind direction to pressure systems • Effect of the Coriolis force in the Northern Hemisphere on moving air • Difference between what the question is asking (meteorology) and what the answer choices describe (light characteristics)

💭 Think About

• When you stand in the Northern Hemisphere with the wind blowing at your face, where is lower pressure generally located relative to your body? Think left/right and ahead/behind. • Ask yourself whether the listed choices describe directions/locations or something completely different. • Consider whether you might be expected to recognize that the set of choices does not match the type of information requested in the question.

✅ Before You Answer

• Review how surface winds circulate around lows in the Northern Hemisphere (counterclockwise and toward the center). • Confirm that each choice (A–D) refers to a type of light characteristic, not a direction or relative bearing. • Before picking anything, be sure the form of the choices can logically answer a question about the location of a low-pressure center.
