Which part of the Sun do solar flares come from?

Which part of the Sun do solar flares come from?

the corona
Solar flares extend out to the layer of the Sun called the corona. The corona is the outermost atmosphere of the Sun, consisting of highly rarefied gas.

Where are solar flares produced?

sunspots
Solar flares are a sudden explosion of energy caused by tangling, crossing or reorganizing of magnetic field lines near sunspots. The surface of the Sun is a very busy place. It has electrically charged gases that generate areas of powerful magnetic forces. These areas are called magnetic fields.

What produces solar flares quizlet?

A solar flare is a rapid variation in brightness seen on the sun. It occurs when magnetic energy built up in the solar atmosphere is released in huge magnetic loops called solar prominences. Sunspots cause auroras, communication blackouts, and usually increased solar flare activity.

What are solar flares on the Sun?

A solar flare is a tremendous explosion on the Sun that happens when energy stored in ‘twisted’ magnetic fields (usually above sunspots) is suddenly released.

Does the Sun have corona?

The corona is the outer atmosphere of the Sun. It extends many thousands of kilometers (miles) above the visible “surface” of the Sun, gradually transforming into the solar wind that flows outward through our solar system.

Where on the sun do solar flares occur quizlet?

Solar flares are sudden eruptions of energy from a small area of the Sun’s surface. They are extremely hot (10 to 20 million degrees Celsius) and extend into the corona. Solar flares occur near sunspots and can disturb radio communications on Earth.

Where on the sun do solar flares most often occur quizlet?

Solar flares usually occur near sunspots. Prominences form arches from one sunspot area to another. Prominences are the most violent of all solar disturbances.

How are solar flares formed?

Solar flares occur when a buildup of magnetic energy on the sun is suddenly released. They usually erupt from sunspots, temporary dark and relatively cool patches on our star’s surface where the local magnetic field is very strong.

Do solar flares leave the Sun?

Solar storms are caused by 11-year Sun cycles that shift the polarity of the energy source’s magnetic field. In the process, flares escape the Sun and hurl towards outer space. A strong solar flare could leave millions of people without power!

How long does it take sunlight to reach Earth?

Light travels at a speed of 299,792 kilometers per second; 186,287 miles per second. It takes 499.0 seconds for light to travel from the Sun to the Earth, a distance called 1 Astronomical Unit.

What is the hottest part of the Sun?

Core
Core. The hottest part of the Sun is the core, at 28,080,000°F, on average.

Where do solar flares and eruptions come from quizlet?

Solar flares arise from energy released when oppositely directed magnetic fields meet each other, like a magnetic field pointing north meets another magnetic field pointing south. Short wavelength photons, high-energy protons and electrons are blasted into space. The meeting of these fields is called a reconnection.

What causes a solar flare on the Sun?

Solar flares are a sudden explosion of energy caused by tangling, crossing or reorganizing of magnetic field lines near sunspots. The surface of the Sun is a very busy place. It has electrically charged gases that generate areas of powerful magnetic forces. These areas are called magnetic fields.

What was the name of the solar flare in 2012?

For the rose variety, see Rosa ‘Sun Flare’. On August 31, 2012, a long prominence/filament of solar material that had been hovering in the Sun’s atmosphere, the corona, erupted out into space at 4:36 p.m. EDT. Seen here from the Solar Dynamics Observatory, the flare caused auroras to be seen on Earth on September 3.

What makes the surface of the sun so active?

The Sun’s gases are constantly moving, which tangles, stretches and twists the magnetic fields. This motion creates a lot of activity on the Sun’s surface, called solar activity. Sometimes the Sun’s surface is very active. Other times, things are a bit quieter. The amount of solar activity changes with the stages in the solar cycle.

Is it possible for a solar flare to destroy Earth?

Given a legitimate need to protect Earth from the most intense forms of space weather – great bursts of electromagnetic energy and particles that can sometimes stream from the sun – some people worry that a gigantic “killer solar flare” could hurl enough energy to destroy Earth, but this is not actually possible.
