2. Carboniferous

3. For glaciation to begin, something needs to cause Earth's temperatures to drop. If this happens, snow that falls on the polar ice caps doesn't melt, and glaciers grow. As snow and ice reflect sunlight, the Earth's temperature is reduced even further, causing glaciers to continue growing.

4. Sea level changes cause marine transgressions and regressions. During a marine transgression, the shoreline moves inland, leaving sedimentary deposits that contain fossils. The shoreline retreats during a marine regression, leaving behind the deposited sediments

Explanation:

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
