  Lab Quiz 1:  1.)  What is occurring at the mid-Atlantic Ridge?     a. The plates are moving apart from one another (diverging) 2.) What happens to the age of the ocean basin as you move from the middle of the Atlantic toward the African coastline?     a. It gets older 3.) Which observation about the Mid-Atlantic Ridge region provides the best evidence that the seafloor has been spreading for millions of years?     d. Seafloor bedrock is younger near the ridge and older farther away. 4.) True or False: Ocean sea floors spread at a consistent rate over time?     a. False 5.) Sea floor spreading is measured using what scale?     a. mm/yr Lab Investigation Photos: Lecture Notes:

 Lecture Notes:  Glacial retreat Sea level rise Paris Agreement:  Global average temp. 2 degrees celsius  Goal: level off greenhouse gas emissions  Principle: differentiate between developed and developing countries  Developed countries must lead the way  Financing: rich countries must donate at least $100 million per year towards this cause  More action is required to reach the Paris Agreement History:  US first to sign the agreement  We pulled away from it and joined only two other countries that refused to sign it: Nicaragua and Syria Syria then signed in Nov. 2017 Nicaragua held out as long as possible! USA isolated on the world stage (largest economy in the world)  What is climate change?  Climate is the average weather at a given point and time of year, over a long period (typically 30 years)  We expect the weather to change, but climate to stay semi constant What is a significant change? How does this depend on the ...

Greenhouse gases:  a gas that absorbs and re-emits infrared light  Earth's "blanket" and light Certain gases in our atmosphere act like a blanket around the Earth Light rays coming from the sun contain visible photons (energetic light particles)  Visible photons are absorbed by Earths' surface and re-emitted as infrared photons We feel infrared photons as heat  Albedo effect The reflectivity of a surface; how much radiation is reflected vs. absorbed COLOR has a major influence on albedo a high albedo means something is more reflective, a low albedo means it is less reflective/will absorb more radiation  albedo = 1 ; completely reflects radiation albedo = 2; completely absorbed radiation Snowball Earth The Atmosphere is dynamic dust is transported from the Saharan Desert to the Amazon Basin air pollutants from China arrive at the coast of California  Donora, PA, 1948  Great London Smog of 1952 Technologies developed to reduce emissions from power plants...
