Question

question 30 (multiple choice worth 3 points)
oss.02earth’s magnetic field

• does not affect solar winds
• is not affected by solar winds
• protects earth from radiations
• creates gravitational forces

question 31 (multiple choice worth 3 points)
oss.01which of these qualities most likely helped kepler construct the scientific explanation of the solar system?

• generosity and helpfulness
• ingenuity and creativity
• assertiveness and flexibility
• consideration and compassion

Explanation:

Question 30

• Option 1: Earth's magnetic field does interact with solar winds (e.g., causing auroras), so it affects solar winds. Eliminate.
• Option 2: Solar winds can distort Earth's magnetic field (e.g., geomagnetic storms), so it is affected by solar winds. Eliminate.
• Option 3: Earth's magnetic field deflects charged particles from solar radiation, protecting Earth. Correct.
• Option 4: Gravitational forces are due to mass, not magnetic fields. Eliminate.

• Option 1: Generosity/helpfulness don't relate to scientific explanation of solar system. Eliminate.
• Option 2: Kepler needed ingenuity (e.g., deriving laws from data) and creativity to model solar system. Correct.
• Option 3: Assertiveness/flexibility aren't key for scientific discovery here. Eliminate.
• Option 4: Consideration/compassion are irrelevant to solar system science. Eliminate.

Answer:

C. protects Earth from radiations
