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.

What is responsible for the mottled appearance of the Sun's surface known as granulation?

Granulation on the Sun's surface is caused by convection currents of hot plasma rising and cool plasma sinking beneath the surface. As hot plasma rises, it cools and begins to sink back down, forming the characteristic mottled appearance.


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 is the bubbling characteristic of the photosphere called?

The bubbling characteristic of the photosphere is called solar granulation. These granules are caused by the convective motion of plasma beneath the surface of the Sun, creating cells of rising hot plasma and sinking cooler plasma that appear as granules on the photosphere.


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.


What is the layer of the sun through which energy travels by convection from the radiative zone to the atmosphere?

From the Sun's core, energy moves through the radiative zone, across the tachocline (transition layer) to the convective zone, and then to the outer convective zone with its visible 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.


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.

Granulation is caused by?

Granulation is caused by an excessive release of inflammatory mediators, such as cytokines, which results in the formation of granulation tissue. Factors like chronic inflammation, repeated injury, or persistent infection can trigger this process. Granulation tissue is part of the normal wound healing response but can become excessive under certain conditions.


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

I think this refers to "granulation".


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.

What are the methods of granulation?

There are two types of granulation they are Wet Granulation and Dry Granulation.Wet granulation and dry granulation depends on the type of fertilizer granulators and whether adding water during granulation.In general, Roll Extrusion Granulator(Azeus Fertilizer Machinery) is dry granulation machine. It requires moisture of raw materials less than 40% and no water added during granulation. So, it's compound fertilizer granules are also dry, in long-stick shape.But, as for New-type Granulator(organic fertilizer by Azeus Fertilizer Machinery) and Pan Granulator (both organic and compound fertilizer), with required a low moisture of raw materials, water must be add during granulation. Or, the fertilizer granulation will fail.


What is the difference between dry granulation and wet granulation?

Wet meaning you wet the ground first with a hose
