The sun's surface has a mottled appearance, known as granulation, because of its convection currents. At any one time, about four million of these currents cover the sun's surface.

What is granulation on the sun caused by?

The grainieness is caused by convective cells at the sun's sufrace. Hooter material rises up at the centers of these "grains" (called granules) while less hot material sinks around their edges. Each granule is several hundred miles across.


Is the sun's surface rough?

Yes, the Sun's surface is not smooth; it has a granular texture due to convection processes occurring in its outer layers. These convective cells create the appearance of "solar granulation," with cells of hot rising material and cooler sinking material.


What is the grainy texture on the sun's surface produced by numerous bright markings called?

The grainy texture on the sun's surface produced by numerous bright markings is called granulation. These granules are the tops of convection cells, where hot plasma rises and cooler plasma sinks in the sun's outer layer.


Why does the surface of the sun appear grainy?

The grainy appearance of the sun's surface, known as granulation, is caused by the convective motion of gases below the surface. Rising hot plasma carries energy to the surface, creating bright granules, while cooler plasma sinks back down, creating darker areas. This continuous churning process gives the sun's surface a granular texture.


What are the 5 surface features of the sun?

The five surface features of the sun are sunspots, solar flares, prominences, faculae, and granulation. These features are caused by the dynamic processes occurring on the sun's surface due to its magnetic field and internal convective motion.

What evidence can you give that granulation is caused by convection?

Granulation on the surface of the Sun is caused by convection currents carrying hot plasma from the interior to the surface. These rising currents of hot plasma create bright cells of gas at the surface, which appear as granules. The motion of these granules is evidence of the convective nature of the Sun's outer layers.


The mottled appearance visible on the surface of the Sun produced by the underlying convection is called?

This effect on the suns photosphere is from large cells or grains which are about 100 km accross. There is hotter rising gas at the centre with falling cooler gas at the edge of these cells, which are constantly shifting every few minutes. These cells or grains are contained within much larger structures called super granules, which are around 30,000 km in size and last for several hours.


What is the bubbling effect seen on the surface of the sun?

I think this refers to "granulation".


Granulation on the Sun's surface is caused by what activity?

Granulation on the Sun's surface is caused by the rising and falling of convection currents below the Sun's surface. Hot plasma rises, cools at the surface, sinks back down, and repeats this process, creating the granular pattern we observe.


The grainy appearance of the sun and surface is due to moving columns of gases called?

The bright markings are "faculae" (plural of facula). However, I wouldn't say that they produce the grainy texture. I think the "granulation" is there even without the faculae.

What is it called when the damage of the epidermis isn't severe and the surface epithelium migrates beneath the dry scab and across the surface of the granulation tissue?

Regeneration


What does lichen blotched mean?

"Lichen blotched" typically refers to a pattern of discoloration on a surface, resembling the appearance of lichens. Lichens are symbiotic organisms consisting of fungi and algae, and their presence can create a mottled or patchy effect on rocks, trees, or other surfaces.


What gives the rough er its bumpy appearance?

The rough endoplasmic reticulum's bumpy appearance comes from ribosomes attached to its surface. These ribosomes are responsible for protein synthesis, and their presence gives the rough ER its distinctive texture.


In which layer of the sun does granulation occur?

Granulation occurs in the photosphere, which is the visible surface of the Sun. It is characterized by the pattern of rising and falling material due to convective currents in the outer layer of the Sun.
