Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In which area of the sun does gas rise as it heats up, then fall back down as it cools?
A
the core
B
the radiation zone
C
the convection zone
D
the corona
Explanation: 

Detailed explanation-1: -Convection Zone: Just beneath the photosphere, and extending inward to about 0.7 Rsun, is the convection zone. Energy generated in the core of the Sun moves outward through this layer by a boiling motion in which hot plasma rises, releases some of its energy, cools, and then sinks again.

Detailed explanation-2: -The Solar Interior Energy is generated in the core, the innermost 25%. This energy diffuses outward by radiation (mostly gamma-rays and x-rays) through the radiative zone and by convective fluid flows (boiling motion) through the convection zone, the outermost 30%.

Detailed explanation-3: -The Convection Zone sun’s interior. Hot gases rise from the bottom of the convection zone and gradually cool as they approach the top.

Detailed explanation-4: -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. The surface of the convection zone is where light (photons) is created.

Detailed explanation-5: -Answer and Explanation: The difference between the radiation zone and the convection zone is as follows: The radiation zone of the Sun is the interior region of the sun, or the core of the Sun, from where the energy is generated due to fusion. The convection zone is the outermost inner layer above the radiation zone.

Detailed explanation-6: -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.
