  1. What did you do in lab today? Temperature:  My group did temperature, as seen on ICON Precipitation:  rising global temperatures are driving major shifts in precipitation snow harms crops by allowing deep soil freezing-snow acts as a insulator which protects soil from freezing. Iowa city is seeing more extreme precipitation, 50% increase in days with more than 4 inches of rain bigger storms = more flooding  regionally there has been more precipitation more floods when it rains --> more drought stress when it doesn't  wet times wetter, dry times drier.  precipitations has increase in inches, numbers of days, and extremities because of an increase in global temperature.  Ag & Plant Life:  We know climate change is happening because Iowa temperatures have increased 1 degree since 1980. Iowa now gets about 4 more inches of rain per year. heavy rainstorms are happening more often. longer growing seasons and increased temperatures allow oppo...

  1. What did you do in lab today? Climate Change  1. What are the primary points in the video? Climate change is not a future problem, it's happening now and affecting millions of people. the documentary showed how burning fossil fuels, deforestation, and industrial farming are major contributors to global warming. Political and economic systems often slow down action, even when solutions already exist. 2. What are the major issues? Not enough people or leaders are taking this issue seriously. Developing countries will suffer the most, even though they contribute the least to the problem. We might reach a point where the damage can't be reversed. 3. What questions do you want us to teach you? What I can personally do to make a difference. Is the world on track to meet the goals from climate agreements?  How can countries switch to renewable energy sources effectively? AI affecting Climate Change Comparisons of Climate Trends  Data collection for Climate Change Corpo...

   1. What did you do in lab today? Water Cycle Evaporation, condensation, precipitation Transpiration Sublimation and De-sublimation Weather occurs in the Troposphere Weather is short term, climate is long-term How did we forecast weather before modern technology? old wives tales Joints hurt biting flies smell the rain Why does weather typically come from the west? direction of rotation of Earth Less dense = warm more dense = cold As the sun comes up, air "warms" up and moves creating a convection cell. Yes, that same convection cell that makes plates move it is windiest when the sun is at it's peak so early afternoon  Air pressure: how much weight the air is pressing down on earth Which brings the moisture? High Pressure vs Low Pressure Low pressure system is when storms are happening or anything other than sunny, pressure is leaving High pressure system is when the warm air is coming down, pressure increases heat rises, cool sinks  Warm Front:  where a warme...

  1. What did you do in lab today? Why do we have earthquakes & volcanoes not on boundaries? Ancient fault lines At one point Iowa was at the edge of the continent, could've been a fault line Fracking drilling of natural gas and oil  this could have an effect of an earthquake due to stress Convection Currents  Surface currents carry warmer, less dense water from the equator to the poles water from deep currents rise to replace water, leaving in surface currents warm water from surface currents replaces colder, denser water that sinks to the ocean floor coldest water: the poles Warmest water: equator arctic waters come down to equator, heat up, then goes back up Alfred Wegener Because the earth was spinning the continents were moving --> this is what he based it on  not strong enough to bring continents together or apart (was laughed at) Layers of the Earth Crust: outer layer of earth Mantle: convection is happening Core: inner most part of Earth --> very ho...

  1. What did you do in lab today? Was not in lab today due to sickness, but looked ICON presentation Two types of waves associated with Earthquales:  P-Waves: can travel through anything S-Waves: Can only travel through liquids S-Waves are Ocean-like P-Waves are slinky-like Types of Volcanoes 1. Composite: can often explode out of their sides - Mount St. Helens Eruption 2. Cinder Cone: Often explode out of the top; the most thought-of example of a volcano - Wizard Island in Oregon  3. Shield: slow flow with huge, sloping sides - Mauna Loa, Hawaii 2. What was the big question?  How do Earth's internal and surface processes shape the planet over time? 3. What did you learn in Thursday's discussion?  Notes: Oldest to youngest layers of the ground, bottom = oldest --> top = youngest White sandstone, siltstone, igneous batholith or limestone, shale, Igneous Dike A, Sandstone A, Conglomerate, Dolostone, Igneous Dike B, Sandstone B, Glacial Debris, surface Earthqua...

  1. What did you do in lab today?   Sand Lab 1: Looks like little rocks, maybe from river 2: more red-ish, maybe from the desert 3: black, looks like rasins, maybe from river 4: white, looks beachy, crystal like, maybe from beach 5: looks crystal, colorful, maybe from cove or cave 6: yellow-ish, small pebbles, from beach maybe or river 7: brown, red-ish, small, from river/jungle 8: Looks same as 7, small, neutral colors, maybe from river or desert 9: looks like coal, black/gray, looks like from volcano (black sand beach) 10: yellow, orange-ish, from desert? maybe a river, bigger pebbles --> abu dhabi  11: little white rocks, looks like little eggs, maybe from desert Fossils Lab Brachiopods - 3 Corals - 5 Most looks like just rocks  we found a lot of coral and big looks rocks/fossils Coral Fossils 2. What was the big question?  How does the discovery of fossils that are millions of years old help us now, in the present? 3. What did you learn in Thursday's dis...
