What are the three main types of rocks?
What is an igneous, sedimentary and metamorphic rocks?

What phase of the moon is completely illuminated?
Full Moon
What type of rock is granite?
Igneous
Which type of rocks forms from cooling magma or lava?
What is an igneous rock?
What rock type is formed from existing rocks undergoing heat and pressure?
Metamorphic
During which phase is the moon completely dark?
New Moon
What is the difference between intrusive and extrusive igneous rocks?
Intrusive rocks cool slowly beneath the surface, forming large crystals; extrusive rocks cool quickly on the surface, forming small or no crystals.
What process forms sedimentary rocks?
What is Compaction and Cementation?
Name the process where magma cools and crystallizes into rock.
Solidification
What is the phase between the New Moon and the First Quarter?

It must melt into magma and then solidify.
What moon phase occurs two weeks after a full moon?
New Moon
What is the approximate time between each full moon?
About 29.5 days
How does heat and pressure transform rocks into metamorphic rocks?
It changes their mineral composition and texture without melting them.
What is the continuous process of rock transformation called?
The Rock Cycle
Why do we always see the same side of the moon?
Because the moon's rotation period matches it's orbit around Earth, a phenomenon called synchronous rotation.
Why does the moon appear to change shape?
Because of the way sunlight illuminates the moon as it orbits Earth.
