Dustbowl …a period of severe dust storms the 1930s. The phenomenon was caused by severe drought combined with poor farming techniques. Grasses in the American prairie were lost , and there was nothing to hold soil in place. During the drought of the 1930s, without natural anchors to keep the soil in place, it dried, turned to dust, and blew away with the prevailing winds. Describe an interaction between two systems during the dustbowl. http://commons.wikimedia.org
Dustbowl The hydrosphere and the geosphere interacted. The lack of water caused the drying out of soil. The biosphere and geosphere interacted. The dying of plants allowed the soil to blow away.
Earth Systems The __________???_________ is composed of all of the water on or near the earth. This includes the oceans, rivers, lakes, and even the moisture in the air. Ninety-seven percent of the earth's water is in the oceans. The remaining three percent is fresh water; three-quarters of the fresh water is solid and exists in ice sheets. http://serc.carleton.edu
Mt. Saint Helen’s …an active volcano in Washington state. It is most notorious for its catastrophic eruption on May 18, 1980. Fifty-seven people were killed during the eruption. A massive landslide triggered by an earthquake measuring 5.1 on the Richter scale caused an eruption that reduced the elevation of the mountain's summit from (2,950 m) to (2,550 m), replacing it with a 1 mile (1.6 km) wide horseshoe-shaped crater. What was the interaction between the geosphere and biosphere in this event? http://en.wikipedia.org
Mt. St. Helen’s • The eruption of the volcano was an event in the geosphere, it caused the destruction of many trees in the biosphere.
Mt. Saint Helen’s The volcano released a large amount of dust and ash into the atmosphere. These particles serve as nuclei for the formation of rain drops. ? -> atmosphere -> ? What systems were interacting? http://en.wikipedia.org
Mt. Saint Helen’s Rainfall often increases following an eruption, stimulating plant growth What systems are interacting? http://en.wikipedia.org
Mt. Saint Helen’s Volcanoes may release a substantial amount of hot lava, which causes mountain glaciers to melt. What systems are interacting? http://en.wikipedia.org
Earth Systems The _______???________ is the solid, rocky crust covering entire planet. This crust is inorganic and is composed of minerals. It covers the entire surface of the earth from the top of Mount Everest to the bottom of the Mariana Trench. http://serc.carleton.edu
Chernobyl … was a catastrophic nuclear accident that occurred on 26 April 1986 in Ukraine. An explosion and fire released large quantities of radioactive particles into the atmosphere, which spread over much of the western USSR and Europe. Contamination from the Chernobyl accident was scattered irregularly depending on weather conditions, much of it deposited on mountainous regions such as the Alps, the Welsh mountains and the Scottish Highlands where radioactive rainfall occurred. What Earth system interaction played a large part in the movement of the contamination? http://www.npr.org
The atmosphere carried the contamination to other parts of the world.
Earth Systems The __________???__________ is composed of all living organisms. Plants, animals, and one-celled organisms are all part of the biosphere. Most of the planet's life is found from three meters below the ground to thirty meters above it and in the top 200 meters of the oceans and seas. http://serc.carleton.edu
Hurricane Sandy …the deadliest and most destructive hurricane of the 2012 Atlantic hurricane season. Sandy developed from a storm in the Caribbean Sea on October 22, quickly strengthened, and was upgraded to Tropical Storm Sandy six hours later. Sandy moved slowly northward toward the Greater Antilles and gradually intensified. On October 24, Sandy became a hurricane, made landfall near Jamaica, re-emerged a few hours later into the Caribbean Sea and strengthened into a Category 2 hurricane. On October 25, Sandy hit Cuba as a Category 3 hurricane, then weakened to a Category 1 hurricane. Early on October 26, Sandy moved through the Bahamas. On October 27, Sandy briefly weakened to a tropical storm and then re-strengthened to a Category 1 hurricane. Early on October 29, Sandy curved north-northwest and then moved ashore in New Jersey with hurricane-force winds. How might this event have affected the Geosphere? http://commons.wikimedia.org
The storm may have washed away parts of coastlines and deposited soil and sand in other places.
Arizona Haboob … a type of intense dust storm carried through the atmosphere. It blows dry, loose silt and clay up from the desert, creating a wall of sediment . They occur during thunderstorm formation. What two systems are interacting during a haboob? http://commons.wikimedia.org
The air in the atmosphere carries soil and dust from the geosphere across the desert.
San Antonio Floods Flash floods can occur under several types of conditions. Flash flooding occurs when rainfalls rapidly on saturated soil or dry soil that does not absorb water easily. The temporary availability of water is often used by plants with rapid germination and short growth cycles. Describe an interaction between this event and the biosphere. http://commons.wikimedia.org
West Chemical Plant Explosion On Oct. 3, 2011, workers were mixing chemicals to make a product used in the wastewater treatment industry. Magnablend began working with this product in August 2011 and prior to the fire had made 16 small batches of 500 gallons each. The day of the fire a large 2,500-gallon batch of product was made. This large batch produced a greater amount of what was thought to be steam coming out of the blender and overwhelmed the ventilation system. If the amount of chemicals increase, then the amount of steam will increase. What is the independent variable in this hypothesis? http://www.nbcdfw.com
2004 Indian Ocean Earthquake and Tsunami …an undersea earthquake off the coast of Indonesia. it is the third largest earthquake ever recorded on a seismograph. It caused the entire planet to vibrate as much as 1 cm and triggered other earthquakes as far away as Alaska. The sea floor is estimated to have risen by several meters, displacing an estimated 30 cubic kilometers of water and triggering devastating tsunami waves. Anthropologists had initially expected the aboriginal population of the Andaman Islands to be badly affected by the tsunami and even feared the already depopulated Onge tribe could have been wiped out. Many of the aboriginal tribes evacuated and suffered few casualties. Oral traditions developed from previous earthquakes helped the aboriginal tribes escape the tsunami. For example, the folklore of the Onges talks of "huge shaking of ground followed by high wall of water". Almost all of the OngePeople seemed to have survived the tsunami. The Onge People are part of what Earth system? earthobservatory.nasa.gov

Earth Systems The _______???_______ is the body of air which surrounds our planet. Most of our atmosphere is located close to the earth's surface where it is most dense. The air of our planet is 79% nitrogen and just under 21% oxygen; the small amount remaining is composed of carbon dioxide and other gasses. http://serc.carleton.edu
Japanese Earthquake On March 11, 2012 an earthquake hit northeastern Japan, spawning an incredibly destructive tsunami and crippled the Fukushima Daiichi nuclear power plant. Newer buildings have less damage from earthquakes than older buildings. What is the dependent variable in this statement? http://commons.wikimedia.org

California Wildfires …an uncontrolled fire in an area of combustible vegetation. On a yearly basis in the United States, typically more than six times the number of wildfires are caused by human means such as campfires and controlled agricultural burns than by natural means. How does this event impact the atmosphere? http://en.wikipedia.org
The fire put a great deal of smoke and ash into the atmosphere.
