Earth Science - Chapter 22

The classification of a coronal mass ejection

Hot plasma rises to the surface, cools, and descends into the sun's interior again

The moon's surface gravity is what fraction of the earth's surface gravity?

The sun's surface exists in what state of matter

Spectacular, rayed crater found in the moon's southern hemisphere

A total solar eclipse is usually longer than a total lunar eclipse

Region within the sun in which energy travels primarily as electromagnetic waves

In what part of the sun are thermonuclear reactions believed to occur

Occurs when the moon is in line with the earth and sun

Line that divides the illuminated and shadowed sides of the moon

The distance from the center of the moon to the center of the earth averages about

Indicates that the sun is rotating on its axis

The phase of the moon seen before the first quarter moon

Compared to the earth, the average density of the moon is

The point in the moon's orbit where it is closest to the earth

Severe solar storms that can disrupt telecommunications on Earth

The pointed jets on the chromosphere

The entire range of electromagnetic waves released by the sun

The sun is compsed mostly of

The radiated energy from the sun travels mostly in the form of electromagnetic waves

An instrument that astronomers use to produce an artificial solar eclipse

The dark areas on the surface of the sun

During the first half of the lunar month the moon is said to be

Large, dark areas on the surface of the moon

The lower layer of the sun's atmosphere

The apparent path that the sun follows through the stars as seen from Earth's perspective

Associated with some craters on the moon which were formed by meteor impacts

The outer region of the sun's atmosphere

The back side and the dark side of the moon are the same

The points on the crescent moon

Of what high-speed particles is the solar wind mostly composed

How many times does the moon rotate during one revolution around the earth?

Sunspots usually last no longer than several hours

The visible surface of the sun

More than 70 of the naturally occurring elements have been identified in the sun

In what phase of its cycle must the moon be for a total lunar eclipse to take place?

A full moon always rises at sunset and sets at sunrise

Streams of plasma material that rise up into and descend from the sun's corona, forming loops

Depressions on the surface of the moon surrounded by circular walls

The sun is located in the center of the Milky Way galaxy
