What is responsible for the mottled appearance of the Sun’s surface known as granulation group of answer choices?
They are caused by convection currents of plasma in the Sun's convective zone directly below the photosphere. The grainy appearance of the solar photosphere is produced by the tops of these convective cells and is called granulation.
What causes granulation quizlet?
Granulation is caused by rising currents of hot gas below the photosphere.
What is the mottled appearance of the Sun called which makes it look like bubbling gravy?
The Sun's surface churns with a bubbling pattern called grannulation.
What are solar granules quizlet?
Granules. Granules on the photosphere of the Sun are caused by convection currents (thermal columns, Bénard cells) of plasma within the Sun's convective zone. The rising part of the granules is located in the center where the plasma is hotter. The outer edge of the granules is darker due to the cooler descending plasma …
What is responsible for the mottled appearance of the Sun’s surface known as granulation quizlet?
extremely hot and extremely thin. Which of these best describes the photosphere? The disk of the Sun that we see. What is responsible for the mottled appearance of the Sun's surface known as granulation? convection currents.
What causes granulation on the Sun?
They are caused by convection currents of plasma in the Sun's convective zone, directly below the photosphere. The grainy appearance of the solar photosphere is produced by the tops of these convective cells and is called granulation.
What is granulation and how is it caused?
Granulation tissue is a sign that the wound is on its way past an often-stubborn inflammatory phase of healing and progressing into the building phase of proliferation.
What is responsible for the sunspots on the Sun’s surface?
Sunspots are caused by disturbances in the Sun's magnetic field welling up to the photosphere, the Sun's visible "surface". The powerful magnetic fields in the vicinity of sunspots produce active regions on the Sun, which in turn frequently spawn disturbances such as solar flares and coronal mass ejections (CMEs).
What is corona of the Sun?
The corona is the outermost part of the Sun's atmosphere. The corona is usually hidden by the bright light of the Sun's surface. That makes it difficult to see without using special instruments. However, the corona can be seen during a total solar eclipse.
What causes granulation in the Sun?
They are caused by convection currents of plasma in the Sun's convective zone, directly below the photosphere. The grainy appearance of the solar photosphere is produced by the tops of these convective cells and is called granulation.
What causes granulation in the photosphere of the Sun?
Close-up views of the photosphere also show patterns of light areas surrounded by darker borders, called "granulation." Similar to the patterns you can see at the top of a pot of boiling water or oatmeal, granulation is caused by heat rising upward to the photosphere from the hotter solar interior.
When astronomers describe granulation of the Sun What are they referring to?
The surface of the Sun is highly mottled or granulated. Each granule is about 1,000 km across. The granulation is produced by the convection (boiling) of the Sun's gases. Each granule is the top of a convection cell that is welling up.
What causes granulation?
Granulation tissue formation is part of a normal healing process. Under certain conditions, such as infection, self-mutilation, or a local reaction to a chronically implanted, foreign material, this tissue grows uncontrollably and becomes very vascular and secretive.
What does granulation show is happening inside the Sun?
Close-up views of the photosphere also show patterns of light areas surrounded by darker borders, called "granulation." Similar to the patterns you can see at the top of a pot of boiling water or oatmeal, granulation is caused by heat rising upward to the photosphere from the hotter solar interior.
What causes granulation on the sun?
They are caused by convection currents of plasma in the Sun's convective zone, directly below the photosphere. The grainy appearance of the solar photosphere is produced by the tops of these convective cells and is called granulation.
What makes up granulation tissue?
Cells and proliferating capillaries are the two major components of granulation tissue. The cells are chiefly fibroblasts and inflammatory cells— macrophages, lymphocytes, plasma cells, and neutrophils depending on the stage and development of the granula- tion tissue and the presence of infection.
What are sunspots caused by?
Exposure to ultraviolet (UV) lights from the sun's rays or tanning beds accelerates the production of melanin, a pigment responsible for your skin color. After years of exposure, melanin may clump together or be produced in higher concentrations, causing sunspots.
What causes sunspots quizlet?
What is the cause of the sunspot cycle on the Sun? Subsurface magnetic fields are twisted by the Sun's differential rotation and break through the surface as sunspots, then gradually cancel each other and return below the surface.
What causes the granular structure on the Sun’s photosphere?
They are caused by convection currents of plasma in the Sun's convective zone, directly below the photosphere. The grainy appearance of the solar photosphere is produced by the tops of these convective cells and is called granulation.
What is responsible for the Sun’s surface and atmospheric activity?
What is responsible for the sun's surface and atmospheric activity? the sun sweeping up interstellar space debris. gravitational interactions between the sun and the planets.
What is a granule on the Sun?
Solar granules are cellular patterns visible in the outer layer (photosphere) of Sun, associated with large scale vertical fluid motions at, and just below, the photosphere. The brighter, central regions correspond to rising hotter fluid, and the darker, narrow lanes correspond to sinking, colder fluid.
What causes granulation Sun?
A granule is a convection cell in the Sun's photosphere. They are caused by convection currents of plasma in the Sun's convective zone, directly below the photosphere. The grainy appearance of the solar photosphere is produced by the tops of these convective cells and is called granulation.
What causes granulation in the photosphere of the sun?
Close-up views of the photosphere also show patterns of light areas surrounded by darker borders, called "granulation." Similar to the patterns you can see at the top of a pot of boiling water or oatmeal, granulation is caused by heat rising upward to the photosphere from the hotter solar interior.
What is formed from granulation tissue quizlet?
Formation of granulation tissue, which late matures to form fibrous scar tissue.
What is granulation tissue quizlet?
Granulation Tissue. Fibrous connective tissue that replaces a clot during wound healing.
What is responsible for the sunspots on the sun’s surface?
Sunspots are caused by disturbances in the Sun's magnetic field welling up to the photosphere, the Sun's visible "surface". The powerful magnetic fields in the vicinity of sunspots produce active regions on the Sun, which in turn frequently spawn disturbances such as solar flares and coronal mass ejections (CMEs).
What causes a sunspot?
Exposure to ultraviolet (UV) lights from the sun's rays or tanning beds accelerates the production of melanin, a pigment responsible for your skin color. After years of exposure, melanin may clump together or be produced in higher concentrations, causing sunspots.
Why is the photosphere granulated?
Granules in the photosphere are caused because there are convection currents of plasma. The grainy appearance of the photosphere is caused by the top of these convective cells and is called granulation.
What is the appearance of granulation tissue?
Granulation tissue often appears as red, bumpy tissue that is described as “cobblestone-like” in appearance. It is highly vascular, and this is what gives this tissue its characteristic appearance. It is often moist and may bleed easily with minimal trauma.
What is granulation tissue?
Granulation tissue is considered a contractile organ, characterized histologically by the presence and proliferation of fibroblasts, keratinocytes, endothelial cells, new thin-walled capillaries, and inflammatory cell infiltration of the extracellular matrix.
