New moon
Full moon
First quarter
Last quarter
Ancient solidified lava channels on the Moon's surface are called ___.

What was discovered about the far-side of the Moon when it was first mapped in 1959?
it was even more heavily cratered with no major maria
pyramids were first seen
the far-side was about the same as the near-side
there were very few mountains
What is meant by the Moon having a "synchronous orbit?"
its orbit matches that of Earth going around the Sun
both the Earth & Moon orbit each other
daylight hours are the same on both the Earth & Moon
the Moon's spin is equal to its revolution around the Earth
Scientists use models of the Sun to better understand how it works. The currently accepted model of the Sun indicates that it has a dense core surrounded by different layers. How is energy transferred from the core of the Sun to its outer layers?
Energy radiates outward from the core as visible light.
Energy is carried inward from the outer layers by convection.
Energy is radiated out from the core first, then carried to the outer layers by convection.
Energy is carried out from the core by convection first, then radiated to the outer layers.
Patrick wants to create a computer model of the Sun's rotation. Which of the following designs would be the most accurate?
He should show the Sun rotating at the same rate as Earth.
He should show the Sun rotating more rapidly at its equator than at its poles.
He should show the Sun rotating and revolving in exactly the same period of time.
He should show the interior and exterior of the Sun rotating at the same rate of speed.
Which statement describes sunspots?
Sunspots have a bright white appearance.
Sunspots occur in the radiation zone of the Sun.
Sunspots occur in areas of extremely low magnetic fields.
Sunspots have lower temperatures than their surroundings.
Scientists have modeled the behavior of the Sun for many years. Some models show how the Sun's magnetic field gets tangled up as the Sun rotates. These tangled magnetic fields can lift extra energy to the surface in an explosive event that releases solar material into space. Which solar event is explained by this model?
auroras
flares
prominences
sunspots
Although scientists are unable to explore the Sun’s layers directly with instruments, they can measure the change in the speeds of the surface layers and the temperature of those layers from Earth. Using this data, scientists have created models of the Sun and we now know that the sunspots that form on the surface are the areas of coolest temperature for this star. At the sunspots, temperatures are merely 3700 Kelvin (K). What does this indirect information about the Sun confirm?
The Sun has a structure similar to Earth's structure.
Storms form on the surface of the Sun, similar to the atmosphere of Earth.
The Sun's photosphere has properties of a solid, similar to the crust of Earth.
Convection occurs in parts of the Sun, similar to convection in the mantle of Earth.
An astronomer sets up her telescope to photograph the Sun during a total solar eclipse. This type of eclipse occurs when the Moon passes between the Sun and Earth. Which layer of the Sun can be viewed during a total solar eclipse?
convection zone
core
corona
sunspots
The level of activity on the Sun, measured by counting sunspots, increases and decreases over a(n) ________ cycle.
11 year
11 month
10 year
100 year
