Question

question: which part of the sun when viewed with a telescope appears to have a grainy surface? answer options: select one of four photosphere transition region chromosphere corona

Explanation:

The photosphere is the visible surface of the Sun. When viewed through a telescope, its surface appears grainy due to the presence of granules (convection cells) caused by convection currents in the Sun's outer layers. The chromosphere is a thin layer above the photosphere, the transition region is between the chromosphere and corona, and the corona is the Sun’s outer atmosphere, none of which have a grainy appearance like the photosphere.

Answer:

A. Photosphere
