Magnetic fields from the Earth's core

The Earth's magnetic field is generated by the movement of molten iron in its outer core, protecting the planet from solar winds and cosmic radiation.

The Earth's magnetic field is influenced by the gravitational pull of the Moon.

The Earth's magnetic field is a result of the presence of large amounts of gold in its core.

The Earth's magnetic field is caused by the rotation of the planet on its axis.

Surface features are solely determined by weathering and erosion

The Earth's interior influences the surface through plate tectonics and volcanic activity.

The Earth's interior has no impact on surface features

The Earth's interior is too far away to affect surface features
