The granulation pattern that astronomers have observed on the surface of the Sun tells us that: a. the Sun is a lot cooler on the inside than on the outside b. the Sun’s surface is made of a thin solid that cracks easily c. hot material must be rising from the Sun’s hotter interior d. the solar wind must consist of very small (low-mass) particles e. the Sun accumulates a lot of dirt and dust because of its large gravity 5. Which statement about the Sun’s rotation is TRUE?
Question
Answer:
c. hot material must be rising from the Sun’s hotter interior
Explanation:
Granulation is the grainy appearance of the solar photosphere produced by the top of the convection cells in the sun.
The grainy appearance are produced by granules on the photosphere of the sun and granules are caused by convection currents of plasma within the sun’s convection zone.
The interior of these granules are brighter (and thus hotter) than the exterior of the granules which are darker.
So, the granulation pattern that astronomers have observed on the surface of the Sun tells us that hot material must be rising from the Sun’s hotter interior.
