Exam 16: The Sun: Our Parent Star

By what mechanism does solar energy reach the Sun's photosphere from the layer justunderneath it?

The Sun is a fairly normal star.

Describe the method of energy production in the Sun. What is the fuel? What is the endproduct? What kind of interactions occur? What is the role of temperature in the process? Couldwe use this process to produce energy on Earth?

Granulation is the most obvious proof of solar convective energy transport.

The Sun's magnetic field is measured by:

How is energy transfer from the solar interior to surface similar to a process in Earth'satmosphere?

The primary source of the Sun's energy is:

The outward pressure of hot gas in the Sun:

Prominences hanging off the limb of the Sun are the same as filaments seen in front of thedisk.

The density of the Sun is most similar to which object?

Large circulation patterns in the Sun, dubbed "Conveyor Belts," that transport material fromthe equator to the poles, then back to the equator at a depth of 300,000 km, take how long tocomplete a cycle?

The number of sunspots and their activity peak about every:

While observing the Sun, you note a large number of sunspots. What can you conclude?

The critical temperature to initiate the proton-proton cycle in the cores of stars is:

The solar winds blow outward from:

At very large distances from the Sun, its corona turns into the solar wind.

The above diagram indicates that:

If the last peak in sunspot numbers occurred in 2013, then the next solar max is ________.

The photosphere is about 100 times the diameter of the Earth, and large sunspots are largerthan our whole planet.

In spite of its high temperature, we observe the solar corona best during ________.
