Sun Rotation and Sunspots

The video explains Galileo's 1612 observation of sunspots, confirming the sun's rotation. Sunspots, interacting with the sun's magnetic field, can cause solar flares. The sun, being gaseous, rotates at different speeds, faster at the equator than the poles. Astronomers use sunspots to measure rotation, with a Carrington rotation taking just over 27 days. The inner sun rotates faster than the outer layers.

Who confirmed the sun's rotation by observing sunspots in 1612?

• Albert Einstein

• Isaac Newton

• Galileo Galilei

• Johannes Kepler

What causes sunspots on the sun's surface?

• Collisions with asteroids

• Changes in the sun's core temperature

• Interaction of plasma with the magnetic field

• Gravitational pull from planets

Why does the sun rotate at different rates?

• It is influenced by nearby planets

• It has varying temperatures

• It is affected by the moon's gravity

• It is a gas and not a solid object

How long does it take for the sun's equator to complete one rotation?

• 30 days

• 24 hours

• 27 days

• 24 days

What is the term for the sun's rotation period at 26 degrees latitude?

• Solar rotation

• Galilean rotation

• Carrington rotation

• Equatorial rotation

Where do astronomers observe the most sunspots?

• At the sun's poles

• Throughout the sun's surface

• At the sun's equator

• 26 degrees above or below the equator

Which part of the sun rotates faster?

• The outer layers

• The inner parts

• The poles

• The equator
