Solar Phenomena and Magnetic Fields

The video discusses various surface features of the Sun, including granules, super granules, sunspots, spicules, filaments, plages, solar flares, and prominences. These features are influenced by the Sun's differential rotation and magnetic fields. Granules and super granules are caused by convection currents, while sunspots and spicules are related to magnetic field activity. Filaments and plages are visible during high solar activity, and solar flares and prominences result from magnetic field disturbances.

What causes the magnetic fields on the Sun to twist, leading to various surface features?

• Solar flares

• Differential rotation

• Convection currents

• Nuclear fusion

What are granules on the Sun's surface?

• Solar flares

• Large sunspots

• Magnetic field lines

• Bubbling features caused by convection currents

How long do granules typically last on the Sun's surface?

• A few days

• Several hours

• 20 minutes

• A few seconds

What distinguishes super granules from regular granules?

• They last longer and are much larger

• They are smaller in size

• They are cooler

• They are found only at the poles

What role do magnetic fields play in the formation of sunspots?

• They cause nuclear fusion

• They prevent heat from reaching the surface

• They create solar flares

• They increase the temperature

What are spicules on the Sun?

• Flame-like structures around sunspots

• Magnetic field lines

• Large sunspots

• Solar flares

What are filaments on the Sun?

• Bright spots

• Dark streaks caused by magnetic fields

• Solar flares

• Granules

What are plages on the Sun?

• Magnetic field lines

• Solar flares

• Bright regions during high activity cycles

• Dark spots

What causes a solar flare to occur?

• Convection currents

• Magnetic fields preventing heat escape

• Nuclear fusion

• Sunspots merging

What are prominences on the Sun?

• Solar flares

• Large arches of material pulled by magnetic fields

• Small sunspots

• Granules
