A convection zone, convective zone or convective region of a star is a layer which is unstable due to convection. Energy is primarily or partially transported by convection in such a region. In a radiation zone, energy is transported by radiation and conduction. Stellar convection consists of mass movement of plasma within the star whic… WebIn the convective zone, the temperatures are cool enough—under 1,800,000 degrees Fahrenheit (1,000,000 degrees Kelvin)—that the atoms in the plasma there can absorb the photons coming outward from the Sun’s radiative zone. The plasma gets very hot, and begins to rise upward out of the Sun.

"WebConvection is one of the ways heat can be transferred from one place to another. It only happens in liquids and gases, and relies on the differences in density between hot matter and cold matter. Convection is important for weather, baking, the Earth's magnetic field and the Sun's plasma flow. " - How dense is the convection zone in the sun

Web5 de jul. de 2024 · The sun's core temperature is around 20,000,000 °K, yet it is not what determines the characteristic electromagnetic radiation emission from the sun, because most of this intense core radiation is absorbed by a layer of negative hydrogen ions outside the sun’s core called the convection layer. The density of the Sun’s core is about 150 grams per cubic centimeter (g/cm³). That is approximately 8 times the density of gold (19.3 g/cm³) or 13 times the density of lead (11.3 g/cm³). Energy from the core is carried outward by radiation. Ver mais The Sun has been called by many names. The Latin word for Sun is “sol,” which is the main adjective for all things Sun-related: solar.

Web20 de abr. de 2024 · The correct answer is that they become denser in the outer part of the convection currents. The interior of the Sun can be differentiated into three regions, on the basis of the kind of conduction of energy that is in action. These are the core, the radiative zone, and the convection zone. WebAlthough there are no fires on the surface of the Sun, the photosphere seethes and roils, displaying the effects of the underlying convection. Photons flowing from below, trapped by the underlying layers, finally escape. This produces a dramatic drop in temperature and density.
