In which region of the Sun do circulating currents of gas transfer heat to the outer layers?
The convection zone is the outer-most layer of the interior. It extends from a depth of 200,000 km up to the visible surface of the Sun. Energy is transported by convection in this region.
In which region of the Sun does energy?
The Core The Core: The core of the sun is the region that extends from the center to about 20–25% of the solar radius. It is here, in the core, where energy is produced by hydrogen atoms (H) being converted into nuclei of helium (He).
What part of the Sun transports energy with currents of rising and sinking gas?
Energy is created in the core of the Sun by nuclear fusion which releases energy that moves by radiation through the radiative zone. After that this energy moves through the convection zone by rising of hot gas and sinking of cool gas.
Where is the convection zone of the Sun?
The convection zone is the outer-most layer of the solar interior. It extends from a depth of about 200,000 km right up to the visible surface. At the base of the convection zone the temperature is about 2,000,000° C.
Which region of the Sun does energy move as waves that transfer from atom to atom?
In the radiative zone, energy is transferred by a process called thermal radiation.
What happens in the corona layer of the Sun?
The mission discovered packets of very hot material called "heat bombs" that travel from the Sun into the corona. In the corona, the heat bombs explode and release their energy as heat.
What energy travels through the radiative zone?
A radiation zone, or radiative region is a layer of a star's interior where energy is primarily transported toward the exterior by means of radiative diffusion and thermal conduction, rather than by convection. Energy travels through the radiation zone in the form of electromagnetic radiation as photons.
In which layer of the Sun does energy move in convection currents?
This repetitive cyclical motion of gases is what is referred to as a convection current. Convection currents are how the energy of the sun is transferred to the sun's outermost layer, the photosphere.
What happens in the transition zone of the Sun?
Transition Region – The transition region is a very narrow (60 miles / 100 km) layer between the chromosphere and the corona where the temperature rises abruptly from about 8000 to about 500,000 K (14,000 to 900,000 degrees F, 7700 to 500,000 degrees C).
How does energy from the sun travel to Earth through radiation through convection through conduction through the movement of particles?
During the day, sunlight heats the ground, which in turn heats the air directly above it via conduction. At night, the ground cools and the heat flows from the warmer air directly above to the cooler ground via conduction.
What do you think happens on the sun’s energy when it passes through the exosphere?
The altitude of the lower boundary of the exosphere varies. When the Sun is active around the peak of the sunspot cycle, X-rays and ultraviolet radiation from the Sun heat and "puff up" the thermosphere – raising the altitude of the thermopause to heights around 1,000 km (620 miles) above Earth's surface.
What happens in the core of the sun?
The core of the Sun is home to billions and billions of atoms of hydrogen, the lightest element in the universe. The immense pressure and heat pushes these atoms so close to one another that they squish together to create new, heavier atoms. This is called nuclear fusion.
What happens in the photosphere zone of the Sun?
The sun's photosphere The term photosphere means "sphere of light" and is the layer where most of the sun's energy is emitted. It takes about eight minutes for sunlight from the photosphere to reach Earth.
How energy moves through each layer of the Sun?
The Radiative Zone – Energy moves slowly outward, taking more than 170,000 years to radiate through this layer of the Sun. The Convection Zone – Energy continues to move toward the surface through convection currents of the heated and cooled gas.
What is the transition region layer of the Sun?
Transition Region – The transition region is a very narrow (60 miles / 100 km) layer between the chromosphere and the corona where the temperature rises abruptly from about 8000 to about 500,000 K (14,000 to 900,000 degrees F, 7700 to 500,000 degrees C).
What happens on the Sun’s energy when it passes through the stratosphere?
Ozone in the lower part of the atmosphere acts as a greenhouse gas and is a major pollutant. Higher up, in the stratosphere, the ozone layer absorbs solar ultra-violet radiation and affects how much of the Sun's heat is radiated back into space.
Where does convection occur?
Convection occurs when heat is transferred through a gas or liquid by the hotter material moving into a cooler area.
What does the mesosphere do?
The mesosphere is the highest of the atmospheric layers in which gases are all mixed up, instead of being layered in terms of their mass. 18. The mesosphere protects the Earth from meteors and asteroids by burning them up before they can reach its surface.
What happens in the mesosphere?
Within the mesosphere, temperature decreases with increasing height, due to decreasing absorption of solar radiation by the rarefied atmosphere and increasing cooling by CO2 radiative emission. The top of the mesosphere, called the mesopause, is the coldest part of Earth's atmosphere.
What does the radiative zone of the Sun do?
Just outside the Inner Core of the sun at a distance approximately 0.25 to 0.7 solar radii lies the Radiative Zone. This zone radiates energy through the process of photon emission and capture by the hydrogen and helium ions.
What is corona and photosphere in sun?
Corona – The corona is the outermost layer of the Sun, starting at about 1300 miles (2100 km) above the solar surface (the photosphere). The temperature in the corona is 500,000 K (900,000 degrees F, 500,000 degrees C) or more, up to a few million K.
What happens in the transition region?
Scientific definitions for transition region The thin layer of the solar atmosphere that separates the chromosphere from the corona. In the transition region, temperatures increase from a relatively cool 20,000°K in the chromosphere to the 1,000,000°K and higher temperatures of the corona.
Where is the transition region?
The transition zone is part of the Earth's mantle, and is located between the lower mantle and the upper mantle, between a depth of 410 and 660 km (250 to 400 mi). The Earth's mantle, including the transition zone, consists primarily of peridotite, an ultramafic igneous rock.
In which layer do convection currents occur?
a. The two layers of the Earth that are involved in forming convection currents are the mantle and the outer core.
What part of the mantle has convection currents?
Convection currents in the magma drive plate tectonics. Heat generated from the radioactive decay of elements deep in the interior of the Earth creates magma (molten rock) in the aesthenosphere. The aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the Earth that extends to 2900 km.
What happens in the stratosphere?
Ozone is formed when three oxygen molecules join together, and this happens in the stratosphere because of the intensity of the sun's ultraviolet radiation.
What is in the thermosphere?
In the upper thermosphere, atomic oxygen (O), atomic nitrogen (N), and helium (He) are the main components of air. Much of the X-ray and UV radiation from the Sun is absorbed in the thermosphere. When the Sun is very active and emits more high-energy radiation, the thermosphere gets hotter and expands or "puffs up".

What happens in stratosphere?
The Stratosphere It contains much of the ozone in the atmosphere. The increase in temperature with height occurs because of absorption of ultraviolet (UV) radiation from the sun by this ozone. Temperatures in the stratosphere are highest over the summer pole, and lowest over the winter pole.
What occurs as energy is transferred through the convective zone of the Sun?
What occurs as energy is transferred through the convective zone of the Sun? Check all that apply. Photons are absorbed by hot gas atoms. Energy is transferred through the large-scale movement of material.
