10/27 and 10/31: introduction to atoms

10/27/11 A/B DayLEQ: 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).
