What does the Mohs scale test for?
The Mohs scale tests for a relative level of hardness. Level 1 being the softest and level 10 being the hardness.
What is precipitation?
Any form of water that falls onto the earth.
True or False? The atmosphere has its own effective self-cleaning mechanisms such as acid rain.
False! ...such as wind blowing and (regular) rain.
