The black spots on the photosphere of the sun are called sunspots.

What are dark spots called on the photosphere called?
The black spots on the photosphere of the sun are called sunspots.
Why do spots appear dark?
Spots appear dark because they are much cooler than the surrounding area. They are still very hot, but not as much as the rest of the Photosphere.
What is the name for dark areas on the photosphere of the sun?
The dark areas on the photosphere of the Sun are called sunspots. These spots are cooler regions caused by magnetic activity, which inhibits the convective flow of heat. Sunspots appear darker than their surrounding areas due to their lower temperature, typically around 1,500 degrees Celsius cooler than the rest of the photosphere.
An area seen as a dark spot on the photosphere of the sun?
The darkest part, where the magnetic field is approximately vertical to the sun's surface is called the Umbra.
Which layer of the sun do sunspots occur on?
I believe that the layer in which sun spots occur would be the chromosphere. The chromosphere is the second layer in the sun's atmosphere and is about 2,000km above the photosphere(the first layer).
What are the dark spots on the photosphere?
Dark spots on the photosphere, known as sunspots, are areas of reduced surface temperature caused by magnetic activity on the Sun. They appear darker than their surroundings because they are cooler and emit less light. Sunspots can vary in size and number over an 11-year solar cycle.
Why do sun spots appear dark?
A typical spot consists of a dark region called the umbra, surrounded by a lighter region known as the penumbra. The sunspots appear relatively dark because the surrounding surface of the Sun (the photosphere) is about 10,000 degrees F., while the umbra is about 6,300 degrees F. Sunspots are quite large as an average size is about the same size as the Earth.
What is called the dark spots of the sun?
sun spots
What are the dark and cooler spots on sun called as?
Dark spots on the Sun are called sunspots. (You knew that was coming, didn't you?)
What makes the sunspots?
Sunspots are temporary phenomena on the photosphere of the Sun that appear visibly as dark spots compared to surrounding regions. They correspond to concentrations of magnetic field that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
What are dark areas on the photosphere on the sun called?
Dark areas on the photosphere of the Sun are called sunspots. They appear dark because they are cooler regions compared to their surrounding areas, which results in decreased luminosity. Sunspots are temporary phenomena that occur in 11-year cycles as part of the Sun's magnetic activity.
What are the dark spots on the sun called?
They are called Sunspots
