What is the Earth's magnetic field?

• A field that extends from the Earth's core to space, interacting with solar wind.

• A field that only exists in the Earth's atmosphere.

• A field that is generated by the Earth's oceans.

• A field that is only present during the day.

How is the Earth's magnetic field generated?

• By the movement of tectonic plates.

• By the movement of convection currents of molten iron and nickel in the Earth's outer core.

• By the rotation of the Earth around the sun.

• By the gravitational pull of the moon.

What causes the convection currents in the Earth's outer core?

• The Earth's rotation.

• The heat escaping from the core.

• The gravitational pull of the sun.

• The movement of ocean currents.

Why does a compass needle point north?

• Because it is attracted to the North Star.

• Because it aligns with the Earth's magnetic field.

• Because it is heavier on one side.

• Because it is affected by the Earth's gravity.

What is a sensor?

• A device that stores data

• A component that transforms physical stimuli into electrical signals

• A tool for measuring time

• A machine for processing food
