Describe the relationship between solar prominences and the Sun's magnetic field.

• Solar prominences are caused by the Sun's gravitational pull on nearby planets.

• Solar prominences are loops of plasma that follow the Sun's magnetic field lines.

• Solar prominences are unrelated to the Sun's magnetic field.

• Solar prominences are caused by the Sun's rotation.

Create a model to demonstrate the Sun's rotation and explain how it affects solar phenomena such as sunspots.

• The Sun rotates uniformly, causing sunspots to appear randomly.

• The Sun rotates faster at the equator than at the poles, influencing the distribution of sunspots.

• The Sun's rotation has no effect on sunspots.

• The Sun rotates slower at the equator, causing sunspots to cluster at the poles.
