Answer:

Explanation: The sun's writhing magnetic fields – caused by the movement of the charged material, known as plasma, it's made of – leads to constant change on timescales from milliseconds to billions of years. We see giant solar eruptions such as solar flares and coronal mass ejections that can last minutes to hours.

Answer:

yes

Explanation:

Because the Sun continues to 'burn' hydrogen into helium in its core, the core slowly collapses and heats up, causing the outer layers of the Sun to grow larger. This has been going on since soon after the Sun was formed 4.5 billion years ago.

How earthquake occur or what happen when it came​
miss Akunina [59]

Hello, welcome to Brainly!

Earthquakes are typically prompted when rock underground suddenly breaks alongside a fault. This sudden launch of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing in opposition to each other, they stick a little. They don't simply slide smoothly; the rocks seize on each other. The rocks are nevertheless pushing towards each other, however now not moving. After a while, the rocks spoil because of all the stress that is built up. When the rocks break, the earthquake occurs. During the earthquake and afterward, the plates or blocks of rock start moving, and they proceed to go till they get caught again. The spot underground the place the rock breaks is known as the focal point of the earthquake. The area proper above the center of attention (on pinnacle of the ground) is called the epicenter of the earthquake.
