Question

question 30 (multiple choice worth 3 points) oss.02 earth’s magnetic field
○ does not affect solar winds
○ is not affected by solar winds
○ protects earth from radiations
○ creates gravitational forces

Explanation:

• Analyze Option 1: Earth’s magnetic field does interact with solar winds (e.g., deflects them), so "does not affect solar winds" is incorrect.
• Analyze Option 2: Solar winds can interact with and affect Earth’s magnetic field (e.g., cause geomagnetic storms), so "is not affected by solar winds" is incorrect.
• Analyze Option 3: Earth’s magnetic field (magnetosphere) deflects charged particles from solar radiation, protecting Earth. This is correct.
• Analyze Option 4: Gravitational forces come from mass, not magnetic fields, so "creates gravitational forces" is incorrect.

Answer:

C. protects Earth from radiations
