The ocean is a “carbon sink,” which means that it removes CO2 (carbon dioxide) from the atmosphere. The ocean currently absorbs about one-third of the CO2 released by the burning of fossil fuels.
However, beyond a certain level of atmospheric CO2, the ocean can no longer act as a carbon sink without it having a negative impact on marine life. When CO2 dissolves in seawater, it leads to decreased pH levels. The ocean becomes less alkaline. This is referred to as ocean acidification.
In this activity, students will learn the pattern of major ocean currents and how they are changed by wind, land and water.
Discuss how a 3-D model illustrates the geology of oil deposits. What challenges do you think petroleum geologists must overcome to recover oil?
What factors affect how easily a fluid can move through sediments? How is this flow rate connected to oil production? In this investigation, you will explore the permeabilities of different materials. You will then use your observations to determine what affects permeability and how this might relate to oil production.
Most people associate petroleum with transportation — but we are surrounded by thousands of other everyday products that come from this vital natural resource. A typical 42- gallon barrel of crude oil yields about 20 gallons of gasoline and 4 gallons of jet fuel. What products come from the other 18 gallons?
The students will set up three demonstrations to observe the properties of water. They will explore the boiling point of water, the freezing point of water, and the ability of water to store heat. These activities can be done individually or as a set.
Rocks break down into smaller pieces through weathering. Rocks and sediment grinding against each other wear away surfaces. This type of weathering is called abrasion, and it happens as wind and water rush over rocks. The rocks become smoother as rough and jagged edges break off. In this activity, you will model how abrasion works.
How can a cave form from solid rock? Most caves are found in limestone, a rock made of materials of calcium carbonate. This rock is unusual because the solid minerals it is made of easily dissolve in weak acids. The most common weak acid in the environment is actually water!
This activity allows you to investigate how often earthquakes of various magnitudes happen within a geographic region of your choice. You will use the online resources of the Incorporated Research Institutions for Seismology (IRIS) to do the investigation. These resources are available at http://www.iris.edu
Have you ever felt an earthquake? What was it like? Where were you? What did you do? More than 143 million people are exposed to potentially damaging shaking in the United States.
