Question

1. choose all that apply. choose two facts about the earths magnetic field. the field generates electricity in the atmosphere that causes lightning. the field shields the earth from charged particles sent out by the sun. the field is created by electricity passing through the crust. the field exists because of the spinning of iron metal in the core.

Explanation:

• Lightning is caused by atmospheric conditions like charge separation in clouds, not the Earth's magnetic field.
• The Earth's magnetic field is generated by the dynamo effect in the outer core (spinning molten iron - nickel alloy), not electricity passing through the crust.
• The magnetic field does shield the Earth from solar wind (charged particles from the sun).
• The geodynamo (spinning of iron - rich material in the core) is responsible for the Earth's magnetic field.

Answer:

• B. The field shields the earth from charged particles sent out by the sun.
• D. The field exists because of the spinning of iron metal in the core.
