The answers were: 1. Over one million; 2. 500 years; 3. humus, sand, clay, silt, or gravel; 4. True; 5. (Take a deep breath—this is a long one.) A siliceous volcanic rock that is heated to make it expand and soften. (You’re right if you said something like, “Peat is volcanic glass that is heated until it puffs up.”)
