What else can I help you with?
Magma that has been forced to the surface during a volcano eruption is called what?
Lava
What is the center portion of a sunspot called?
The center portion of a sunspot is called the umbra. It is the darkest part of the sunspot where the magnetic field is strongest and the temperature is cooler than the surrounding areas.
What is outer portion of a sunspot called?
umbra
Magma that has reached the surface is called what?
Lava.lavaThis is known as lava.
What is molten rock called when it reaches the Earth's surface?
Molten rock from under the surface (called 'magma') that reaches the Earth's surface and flows out is is called 'lava'.
What is a cooler area on the sun's surface?
An area on the sun that is cooler is called a sunspot.
A darker area on the surface of the Sun is called a?
Sunspot
What is the small sunspot called?
A small sunspot is called a plage. Plages are regions on the Sun's surface that appear brighter than their surroundings due to intense magnetic activity.
What is a cooler area on the sun called?
A cooler area on the sun is called a sunspot
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.
A dark area of gas on the suns surface that is cooler than surrounding gases?
The dark area is known as a sunspot on the Sun's surface. Sunspots appear darker because they are cooler than their surroundings. They are caused by strong magnetic activity that inhibits convection and reduces temperature.
Magma that has been forced to the surface during a volcano eruption is called what?
Lava
What is an area on the sun cooler than any other area on the sun called?
A cool, dark area on the sun's surface is called a sunspot. Sunspots are areas of reduced temperature that appear dark against the brighter background of the surrounding solar surface because they are regions of concentrated magnetic field flux inhibiting convective flow.
What is the center portion of a sunspot called?
The center portion of a sunspot is called the umbra. It is the darkest part of the sunspot where the magnetic field is strongest and the temperature is cooler than the surrounding areas.
What is the darkened area of a sunspot called?
The darkened area of a sunspot is called the umbra. It is the central region of a sunspot where the magnetic field is strongest, causing the area to appear darker compared to the surrounding photosphere of the Sun.
Have you seen the dark spot on the sun what is it called where it is formed what causes it?
Yes I have seen a dark spot on the Sun. It is called a "Sunspot". It is formed on the Sun's surface which is called the "photo-sphere" and is caused by a loop of the Sun's magnetic field poking though the Sun's surface.
What is a sudden eruption from the surface of a star?
The sudden eruption from the surface of a star is called a plasma ejection. It is also known as a coronal mass ejection. They can be very dangerous if they happen to eject toward a planet nearby.
