Question 1

The study of waves inside the sun is called _____.&#10;A) solar waveology&#10;B) solar seismology&#10;C) corona holes&#10;D) photospheric waves

Accepted Answer

Solar seismology is the correct term for the study of waves inside the sun, analogous to how seismology refers to the study of waves (or seismic activity) within the Earth.

Question 2

The sun does not expand or contract because it is in a state of ______.&#10;A) convective equilibrium&#10;B) coronal equilibrium&#10;C) photosphere equilibrium&#10;D) hydrostatic equilibrium

Accepted Answer

The sun maintains its size because it is in a state of hydrostatic equilibrium, where the inward gravitational force is exactly balanced by the outward pressure of nuclear fusion at its core.

Question 3

This part of the sun's atmosphere is at a temperature about 1,000,000 K:&#10;A) photosphere&#10;B) chromosphere&#10;C) corona&#10;D) spicule

Accepted Answer

The corona is the outermost part of the sun's atmosphere and is known for its extremely high temperatures, around 1,000,000 K or even higher, which is much hotter than the surface of the sun itself.

Question 4

Granulation on the Sun is evidence of&#10;A) convection in the photosphere.&#10;B) seismic activity in the core of the Sun.&#10;C) magnetic activity in the corona.&#10;D) spicules in the chromosphere.

Accepted Answer

Granulation on the Sun is caused by convection currents in the photosphere. These currents bring hot plasma from the interior of the Sun to the surface, where it cools and sinks back down, creating a mottled appearance known as granulation.

Question 5

The pressure equation for inside the sun is ___.

Accepted Answer

The answer of The pressure equation for inside the sun...

Question 6

The outer 2/3 of the sun moves energy by _____.

Accepted Answer

The answer of The outer 2/3 of the sun moves...

Question 7

The core of the sun moves energy primarily by convection.

Accepted Answer

The core of the sun moves energy primarily by radiation, while convection occurs in the outer layers.

Question 8

A good analogy for magnetic waves in the solar atmosphere is similar to cracking a whip.

Accepted Answer

This analogy is used because magnetic waves in the solar atmosphere can propagate in a similar manner to the way energy is transferred along a whip, culminating in a rapid release of energy at the end, akin to the snap of a whip. This illustrates the dynamic and powerful nature of magnetic phenomena in the solar atmosphere, such as solar flares and coronal mass ejections.
