How does the convection zone work on the sun?
The convection zone is how the energy from the core is transported to the photosphere. The plasma is heated, rises to near the surface, cools and then falls back toward the core to be heated again.
Describe in general the structure and interior density pressure and temperature conditions of an average star such as the Sun?
The interior of an average star is modeled after the theoretical pressure, temperature, and density conditions that would be necessary to produce the observed energy and light from the surface. The interior can be described as (1) the core, (2) a radiation zone, and (3) the convection zone. The core is a dense and very hot region where the density fo the core is about 12 times that of solid lead. The radiation zone is less dense and energy in the form of gamma and x rays from the core is absorbed and reemitted by collisions with atoms in this zone. The convection zone begins about seven-tenths of the way to the surface, where the density of the gases is about 1% of the density of water. Gases at the bottom of this zone are heated by radiation from the radiation zone below, expand from heating, and rise to the surface by convection.
Is the moon surface becoming hot an example of convection?
yes
Define the sun's convection zone?
A region of turbulent plasma between the suns core and its visible photosphere at the surface, through which energy is transferred by convection. In the convection zone, hot plasma rises, cools as it nears the surface, and falls to be heated and rise again.
How does the heat produced in the core get to the surface of the sun?
Convection and radiation move the heat from the core of the Sun to its surface.
How is heat transferred from the interior to the surface of Earth?
Via convection currents and hot spots in the mantle.
Does heat from the earths interior reaches earth through conduction?
Heat from the earth's interior reaches the surface through a combination of convection and conduction.
What does the mantle convection cause?
Mantle convection is the slow motion of the Earth's silicate mantle, caused by convection currents that carry heat from the interior to the surface of the Earth. Mantle convection causes the tectonic plates to move around the Earth's surface, causing earthquakes, tsunamis, and volcanic activity.
What drives the slow movement of the plates and the convection?
Mantle convection is the slow creeping motion of Earth's rocky mantle caused by convection currents carrying heat from the interior of the earth to the surface. It is the driving force that causes tectonic plates to move around the Earth's surface.
Is the convection layer the middle layer of the sun where nuclear fusion takes place?
The Sun's fusion takes place in the core. The Convective zone brings heat to the surface by thermal convection, which is basically hot plasma coming up to the surface, then cooling and sinking.
What will happen to the convection currents in the mantle if earth's interior cools down?
Convection currents are transferring heat to the surface through the movement of mantle rock. If the interior of the planet cools, the mantle rock would be too solid to move, and there would be no heat to transfer.
How is heat from earths interior transferred to earths surface by convections?
Beneath the surface of the earth temperature remains the same. Within the Earth, irregular convection cells within the mantle transfer heat from the core to the surface of the planet. Volcanoes and earthquakes are two examples of heat transferring from the interior to the surface.
How does the convection zone work on the sun?
The convection zone is how the energy from the core is transported to the photosphere. The plasma is heated, rises to near the surface, cools and then falls back toward the core to be heated again.
Cooling of the human body using Convection?
Convection involves heat loss in direct proportion to the amount of air or water the pass over the surface. Moving air cools faster than stagnant air.
Name and describe the regions in the interior of the Sun?
the regions are, in order from surface to center: the surface, which is 10,000 degrees F. then there is the convection zone, then the radiation zone. Finally, we reach the core which is 27,000,000 degrees F.
How is energy transferred from the core to the surface of sun by convection?
By convection
Is heating of air touching a hot surface conduction or convection?
convection
