Ice Cores and What They Tell Us About Earth's Climate kp20205 https://padlet.com/lisle202/txv38jj3dyaa/wish/333237103 Ice cores contain microscopic dust particles and minute amounts of chemicals. These were present as tiny droplets or particles in the atmosphere, became incorporated into snowflakes or deposited onto the ice through dry deposition, and were then buried in the snow. These dust particles and chemicals provide important clues into past atmospheric chemistry. One example weʼve seen is that atmospheric dust changes dramatically between glacial periods ("ice ages") and warmer interglacial periods (such as today).]]> 2019-02-20 15:58:54 UTC https://padlet.com/lisle202/txv38jj3dyaa/wish/333237103 13. How have sea levels fluctuated over the last several thousand years? ls this driven by natural circumstances or is this caused by human influence. ln your opinion, why? kp20205 https://padlet.com/lisle202/txv38jj3dyaa/wish/333937412 Between 1900 and 1990 studies show that sea level rose between 1.2 millimeters and 1.7 millimeters per year on average. By 2000, that rate had increased to about 3.2 millimeters per year and the rate in 2016 is estimated at 3.4 millimeters per year. Sea level is expected to rise even more quickly by the end of the century. This is driven by human activity because sea levels started rising after we started burning coal, etc.,,]]> 2019-02-21 21:55:24 UTC https://padlet.com/lisle202/txv38jj3dyaa/wish/333937412 14.

How does carbon dioxide trap infrared radiation on Earth? kp20205 https://padlet.com/lisle202/txv38jj3dyaa/wish/333938067 The energy from the photon causes the CO2 molecule to vibrate. Shortly thereafter, the molecule gives up this extra energy by emitting another infrared photon.

How can cloud coverage both complicate the heating of Earth and also help alleviate the heating of Earth? kp20205 https://padlet.com/lisle202/txv38jj3dyaa/wish/334650599 The sun's rays are reflected off the cloud droplets back into space. Therefore, less of the sun's energy is able to reach the earth's surface, which causes the earth to heat up more slowly. This leads to cooler temperatures.]]> 2019-02-25 00:15:24 UTC https://padlet.com/lisle202/txv38jj3dyaa/wish/334650599 20.

Carbon dioxide has been associated with the warming of Earth. You have learned in Biologyclass that carbon dioxide in the atmosphere is taken out of the air by plants and trees throughphotosynthesis and replaced with breathable oxygen. a.
