What are the characteristics of the photosphere?

Jan 19, 2017 · Why does the photosphere appear granulated? The granulated appearance is the surface effects of convection currents just below the photosphere. 3. In general, the photosphere’s temperature decreases (increases/decreases) with height, and the chromosphere’s temperature increases (increases/decreases) with height. 4.

What is the sun's photosphere?

Why do sunspots appear dark? They have relatively lower temperatures than the brighter, background photosphere. 11. During periods of low solar activity just after solar minimum, what is true of the location and distribution of sunspots? They tend to cluster at high solar latitudes. 12. The solar wind blows out of the coronal holes. 13.

What are the characteristics of the photospheric supergranulation?

Jun 07, 2016 · Why does the photosphere appear granulated? ______the granules are caused by convection currents. The appearance is produced by the tops of the convection cells . _ 3. In general, the photosphere’s temperature _ increases _ (increases/decreases) with height, and the chromosphere’s temperature ___ decreases ____ (increases/decreases) with height.

What happens to the photosphere as it moves outward from the Sun?

A. Core - Where energy is released B. Radiative zone - Where energy is transported primarily by photons C. Chromosphere - Middle atmosphere D. Corona - Outer atmosphere E. Photosphere - Visible surface F. Convection zone - Where energy is transported primarily by rising hot gas Why is the photosphere granulated? Each granule is an upwelling of ...

What is the visible surface of the Sun?

The photosphere is the visible surface of the Sun that we are most familiar with. Since the Sun is a ball of gas, this is not a solid surface but is actually a layer about 100 km thick (very, very, thin compared to the 700,000 km radius of the Sun).

How is the Sun's rotation detected?

This rotation was first detected by observing the motion of sunspots in the photosphere. The Sun's rotation axis is tilted by about 7.15 degrees from the axis of the Earth's orbit so we see more of the Sun's north pole in September of each year and more of its south pole in March. Since the Sun is a ball of gas it does not have ...

How long does it take for the Sun to rotate?

In fact, the Sun's equatorial regions rotate faster (taking about 24 days) than the polar regions (which rotate once in more than 30 days).
