What is igneous rock?
The color of a mineral’s powder.
What is streak?

This Moon phase is halfway lit on the right side.
What is First Quarter?

What is sedimentary rock?
A mineral’s shine is called this.
What is luster?
Why do flat maps always have distortion?
Because Earth is curved and can’t be flattened perfectly.
More than half lit and still growing.
What is Waxing Gibbous?

What is the Mohs scale?
Name Earth’s four main spheres.

Why is color not always reliable for identifying minerals?

Because the Moon is on the opposite side of Earth from the Sun.
Explain why the rock cycle never stops.
Because rocks are always being weathered, melted, compacted, or uplifted.
Name all four main mineral tests.
What are color, streak, luster, and hardness?
Explain why areas outside the tropics see big changes in the Sun’s path during the year.
Because Earth’s tilt causes the Sun to appear higher or lower in the sky depending on the season.
