What is the direct cause of sunspots?
Sunspots appear dark because they are "cooler" than the surrounding gas of the photosphere. Sunspots appear dark because they are hotter than the surrounding gas of the photosphere. Flares are caused by magnetic disturbances in the lower atmosphere of the Sun.
Why couldn’t you stand on the Sun’s surface?
Why couldn't you stand on the Sun's surface? The Sun doesn't have a solid surface.
What is a sunspot cycle quizlet?
solar cycle. Also called the sunspot cycle. An 11-year cycle during which the number of sunspots rises to a maximum or falls to a minimum. The periodic change in the number of sunspots; the cycle is taken as the interval between successive minima and is about 11.1 years.
When the chromosphere can be seen during a solar eclipse it appears quizlet?

What causes sunspots to occur quizlet?
What is the cause of the sunspot cycle on the Sun? Subsurface magnetic fields are twisted by the Sun's differential rotation and break through the surface as sunspots, then gradually cancel each other and return below the surface.
Has anyone been to the Sun?
No. Outside mythology, no human has ever attempted to travel to the Sun. The main reason is fairly obvious—it's too hot. Even in a well-protected spacecraft, you could only get within about 2 million kilometres (1,300,000 mi) before burning up.
Can you walk on the Sun?
You can't stand on the surface of the Sun even if you could protect yourself. The Sun is a huge ball of heated gas with no solid surface. The Sun's surface is always moving. Sometimes storms bigger than the size of Earth can send gas and energy flowing into space.
What causes sunspots astronomy quizlet?
What is the cause of the sunspot cycle on the Sun? Subsurface magnetic fields are twisted by the Sun's differential rotation and break through the surface as sunspots, then gradually cancel each other and return below the surface.
What are sunspots and what do they tell us about the Sun?
Sunspots: One interesting aspect of the Sun is its sunspots. Sunspots are areas where the magnetic field is about 2,500 times stronger than Earth's, much higher than anywhere else on the Sun. Because of the strong magnetic field, the magnetic pressure increases while the surrounding atmospheric pressure decreases.
What is the area in the Sun’s atmosphere that is located above the chromosphere where the temperature rises dramatically called?
The density of the Sun is most similar to which object? The area in the Sun's atmosphere located above the chromosphere (1,500-10,000 km) where the temperature rises dramatically is called the: A. transition zone.
What layer can solar material escape into space and flow outward through the solar system?
The uppermost portion of the Sun's atmosphere is called the corona, and is surprisingly much hotter than the Sun's surface (photosphere)! The upper corona gradually turns into the solar wind, a flow of plasma that moves outward through our solar system into interstellar space.
How do you get rid of sunspots naturally?
Glycolic acid is one of the strongest performers when it comes to fading sunspots and, yes, it's natural. Glycolic acid can be sourced from natural substances and is one of the most effective techniques for fading the dark discoloration of hyperpigmentation.
Why is my face darker without sunlight?
Darker areas of skin (or an area that tans more easily) occurs when you have more melanin or overactive melanocytes. Bronzing of the skin may sometimes be mistaken for a suntan. This skin discoloration often develops slowly, starting at the elbows, knuckles, and knees and spreading from there.
What process generates the sunspot cycle?
As the formation of sunspots approaches the Sun's equator, the polarity of the Sun flips. Thus, the north magnetic pole becomes the south magnetic pole and vice versa. The polarity of the sunspots also changes at this time. The cycle then repeats for another 11 years with the magnetic poles of the Sun flipped.
Why do sunspots appear to be darker than their surroundings?
All in all, the sunspots appear dark because the are darker than the surrounding surface. They're darker because they are cooler, and they're cooler because of the intense magnetic fields in them. Is there any image of the sunspot alone, so that we can see that it's actually pretty bright?
Did NASA actually touch the sun?
CAPE CANAVERAL, Fla. — Sixty years after NASA set the goal, and three years after its Parker Solar Probe launched, the spacecraft has become the first to "touch the sun." The Parker Solar Probe has successfully flown through the sun's corona, or upper atmosphere, to sample particles and our star's magnetic fields.
Can the sun be touched?
It's official: Humans have used a spacecraft to "touch the sun" and revealed some unusual insights about our star. The Parker Solar Probe successfully flew through the sun's corona, or upper atmosphere, to sample particles and our star's magnetic fields. This NASA goal was 60 years in the making.
Can we touch the Sun?

How is a sunspots formed quizlet?
The differential rotation of the sun and its magnetic lines are the cause of sunspots. The rotation of the sun stretches the magnetic cables. After wrapping themselves around the sun, some buckle and pop through the photosphere, thus, forming a pair of spots of opposite polarity.
How are sunspots created quizlet?
Sunspots are caused by very strong magnetic fields on the Sun. The best way to think about the very complicated process of sunspot formation is to think of magnetic "ropes" breaking through the visible surface (photosphere) of the Sun.
What is a sunspot and how often do they occur?
They are regions of reduced surface temperature caused by concentrations of magnetic flux that inhibit convection. Sunspots appear within active regions, usually in pairs of opposite magnetic polarity. Their number varies according to the approximately 11-year solar cycle.
Why do sunspots appear dark in pictures of the Sun?
Why do sunspots appear dark in pictures of the Sun? They are too cold to emit any visible light. They are extremely hot and emit all their radiation as X-rays rather than visible light. They actually are fairly bright, but appear dark against the even brighter background of the surrounding photosphere.
What is the layer of the Sun’s atmosphere that gives off visible light?
the photosphere The inner layer of the sun's atmosphere is called the photosphere. The Greek word photos means “light”, so photosphere the sphere that gives off visible light. The sun does not have a solid surface, but the gases of the photosphere are thick enough to be visible.
How do you survive a solar storm?
Fill plastic containers with water and place them in the refrigerator and freezer if there's room. Leave about an inch of space inside each one because water expands as it freezes. This chilled or frozen water will help keep food cold during a temporary power outage.
Can sunspots be removed?
Cryotherapy. Cryotherapy removes sunspots and other skin lesions by freezing them off with a liquid nitrogen solution. Nitrous oxide may be used (instead of liquid nitrogen) for the treatment of superficial dark spots, such as sunspots, because it's not as aggressive and is less likely to cause blistering.
Why is my neck turning black?
Causes of black neck The main causes of the black neck could be obesity and as well as high insulin levels. Some other causes of the black neck include cholesterol medicines, oral contraceptives, hormonal fluctuations and hypothyroidism.
Why is my skin turning black?
Darker areas of skin (or an area that tans more easily) occurs when you have more melanin or overactive melanocytes. Bronzing of the skin may sometimes be mistaken for a suntan. This skin discoloration often develops slowly, starting at the elbows, knuckles, and knees and spreading from there.
Are sunspots temporary?
Sunspots are phenomena on the Sun's photosphere that appear as temporary spots that are darker than the surrounding areas. They are regions of reduced surface temperature caused by concentrations of magnetic flux that inhibit convection.
What is the sunspot theory?
Sunspots develop and persist for periods ranging from hours to months. Scientists have a theory as to what causes sunspots. It is believed that the rotation of the sun causes distortion in the magnetic field. These distortions cause magnetic areas to break through the photosphere, resulting in what we see as sunspots.
