What is the cooler areas of the Sun called?

What is the cooler areas of the Sun called?

Sunspots are darker, cooler areas on the surface of the sun in a region called the photosphere. The photosphere has a temperature of 5,800 degrees Kelvin. Sunspots have temperatures of about 3,800 degrees K. They look dark only in comparison with the brighter and hotter regions of the photosphere around them.

What is a dark area on the surface of the Sun that is cooler than the surrounding areas?

Sunspots are dark, planet-sized regions that appear on the “surface” of the Sun. Sunspots are “dark” because they are cooler than their surroundings.

What are the cooler & darker areas on the Sun’s photosphere called?

Sunspots are dark areas in the Sun’s photosphere, which are cooler than their surroundings. They generally appear in pairs or groups, and are associated with very strong magnetic fields. The number of sunspots vary in a cycle lasting about 11 years.

What are the coolest areas of the Sun called?

While the center of the Sun’s core can get as hot as 30 million degrees F, its outer layers cool down. The photosphere, which is outside the core, is the coolest layer.

What are the dark areas on the surface of the Sun quizlet?

Sunspots are dark areas on the surface of the Sun that are cooler than surrounding areas. They appear in groups, vary in size, and cycle in number over an 11-year period. Solar flares are sudden eruptions of energy from a small area of the Sun’s surface.

What is the black spot on the Sun?

Sunspots are temporary phenomena on the Sun’s photosphere that appear as spots darker than the surrounding areas. 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.

What are the dark areas on the surface of the sun Brainly?

Sunspots are darker, cooler areas on the surface of the sun in a region called the photosphere. The photosphere has a temperature of 5,800 degrees Kelvin. Sunspots have temperatures of about 3,800 degrees K. They look dark only in comparison with the brighter and hotter regions of the photosphere around them …

What is photosphere and chromosphere?

Photosphere – The photosphere is the deepest layer of the Sun that we can observe directly. Chromosphere – The chromosphere is a layer in the Sun between about 250 miles (400 km) and 1300 miles (2100 km) above the solar surface (the photosphere).

Why are sun spots dark quizlet?

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. The Sun’s gravity inward and the force of gas pressure pushing outward.

Why do sunspots appear as dark spots on the surface of the Sun Brainly?

Sunspots appear dark (in visible light) because they are much cooler than the rest of the surface of the Sun.

What is the cooler, darker area on the surface of the Sun?

Sunspots are dark areas in the sun, they appear dark because they are cooler than the rest of the sun’s surface. Sunspots are Storms in the lower atmosphere of the sun. They may be small as #16# kilometers in diameter or as large as #160,000# kilometers in diameter. The number of sunspots that appear on the sun at any one time is always changing.

What makes sunspots appear on the surface of the Sun?

DETAILS » Sunspots appear as dark patches in the solar photosphere. These are areas where strong magnetic field has emerged from below the solar surface. The strong magnetic field suppresses the release of heat into the photosphere making sunspots cooler than their surroundings.

Which is the visible surface of the Sun?

The visible surface of the Sun, the photosphere, is the layer below which the Sun becomes opaque to visible light. Ever-changing, it is not a solid surface. The movie opens with a full-disk view of the Sun in visible wavelengths.

What happens if the core of the sun becomes hotter?

Suppose that, for some unknown reason, the core of the Sun suddenly became hotter. Which of the following best describes what would happen? A) Higher temperature would cause the rate of nuclear fusion to rise, which would increase the internal pressure, causing the core to expand and turn the Sun into a giant star.
