Living in a greenhouse
- People say the atmosphere is like the glass in a greenhouse; mostly transparent to short-wave
Finding two: greenhouse gases have increased
- CO2 concentrations have increased since the mid-180

Pollution weather: Inversions
- Temperature inversions occur when warmer (less dense) air lies above cooler (more dense air).
How do they develop?
o Radiaive cooling of th surface
o Advection of warmer air over colder air

circulation of the atmosphere and the oceans
What happens if Net radiation > 0

CHAPTER 11: WIND - A GLOBAL GEOLOGIC PROCESS!
11.1 WHY DOES WIND BLOW?!
What is Wind?"
Wind: motion in the atmosphere"
Movement of gas molecules occurs because of atmospheric convection!
Temperature determines atmospheric density"

9.1 WHAT IS A GLACIER?!
Glacier: an accumulation of snow and ice that is thick enough to ow under its own weight"

CHAPTER 7 SUMMARY!
7.1 WHERE DOES WATER COME FROM!
Streams are both owing water in channels that drain from land and are agents of sediment
Complex features govern streams:!
Physics of owing water!
the ease of erosion of geologic materials
Chapter 8: Water Flowing Underground!
8.1 WHAT IS GROUND WATER AND WHERE IS IT FOUND!
Originates as rain water and snowmelt"
Ground Water: Water below the Earths surface that moves slowly through pore spaces and
fractures within regolith and rock"
