LEQ: How can we determine the structure
of an atom using the periodic table?
1. Why would the climate get COOLER after a
volcano?
2. Ice and water break down a rock. What type of
weathering is this?
3. What percent of species have gone extinct?
4. Why would we not find many fossils from the
Precambrian time?
5. Copy and complete: More carbon dioxide in the
atmosphere makes the climate (hotter/colder).
