Basic
1. Uniformitarianism is that the laws of nature have not changed in the course of time. The present is the key to the past, so it helps geologists today find out about the worlds past.
2. present is the key to the past

Climate
1. Human activity has increased CO2 in the atmosphere causing the earth's temperature to rise. The amount of greenhouse gases determines the earth's climate. Low greenhouse gases can cause a decrease in temperature leading to an ice house and high greenhouse gases can cause an increase in temperature leading to hot house conditions.
2. Shrinking sea ice on global temperatures forces the sea level to rise
3.
4. The melting of glaciers affect Charleston by increasing the sea level, eventually flooding charleston.
5.
6. cool summers promote growth of glaciers
7. Long term swings between hot house and ice house conditions can be correlated with the amount of greenhouse gases. Without greenhouse gases, the earths average climate is -18 degrees celcius.
8. increase co2, increase temperature
9. a moving body of ice and snow, lying mostly on land. glaciers form where more snow accumulates in winter than melts in the summer.
10. Albedo is the fraction of solar energy (shortwave radiation) reflected from Earth back into space. If higher mountains have more snow, there is an increase in albedo.
11. the sun's rays get absorbed into the ozone and lose enrgy that
