consequences of climate warming: evidence
historical record
fossil record
rock types ( reefs,glaciers, sand dunes...)
assessing global warming
if global equivalent of CO2 levels increase, global temperature should increase
we can predict how much do temperatures increase
compare our predictions with observations
can we make policy ( about fossil fuels) based on this science?

Final Review

• ocean floor - age magnetic stripes 
• types of seismic waves 
• body waves - passes through the interior of the earth 
• yosemite- land lock hot spot 
• hawaii- ocean hot spot 
• goelogic structure anticline and sincline 
• anticline - up 
• sincline - down 
• anticline- flows away from the axis 
• sincline- flows towards the axis 
• japan - subduction zone ( bumpy trenches) 
• an important characteristic of an index fossil is the organism existed for a relatively short period of geologic time 
•  andesite is not a type of sedimentary rock 
• short term climate cycles include volcanoes, anthropogenic, albedo 
• A water table aquifer is also known as a 
• when maximum tilt occurs weather is more severe
• albedo is also known as the reflection coefficient 
• the goemetry of the water table tend to follow the topography 
• a normal fault is when the hanging wall block moves down with respect to the footwall block 
• felsic refers to rocks that have a higher percentage of light colored minerals and silica (sio2) 
• the rock breccia always contains which of the following: angular gravel-sized fragments '
• metamorphic textures include - foliated, non-foliated 
• which of the following minerals is most likely to be abundant in a mafic igneous rock - audite ( pyroxene) 
• the parent rock or protolith of slate is shale 
• which of the following describes the configuration of an unconfined water table around a pumping well- cone of depression 
• a common strategy to clean up groundwater involces determining the water table because contaminents flow with the direction of groundwater flow 
• climate- long periods of time 
• weather- short period of time
