The JOIDES Resolution is an amazing ship that contains all the equipment necessary to drill into the ocean floor for samples of rock and sediment: a derrick, drill pipe, drilling tools, and drill bits. Once the cylindrical core sample arrives on the rig floor, the drill crew passes the 10 m core to technicians. They, in turn, carry it to the catwalk, where it is cut into 1.5 m sections and labeled. After the core is brought up on deck, the technicians notify the rest of the crew by yelling: "CORE ON DECK!"
One of the most frightening and destructive phenomena of nature is a severe earthquake and its terrible aftereffects. An earthquake is a sudden movement of the Earth, caused by the abrupt release of strain that has accumulated over a long time. For hundreds of millions of years, the forces of plate tectonics have shaped the Earth as the huge plates that form the Earth's surface slowly move over, under and past each other. Sometimes the movement is gradual. At other times, the plates are locked together, unable to release the accumulating energy. When the accumulated energy grows strong enough, the plates break free. If the earthquake occurs in a populated area, it may cause many deaths and injuries and extensive property damage.
To allow students to produce a "marketable" product made from minerals that are used by most people every day. Both the abrasive and cleansing compounds found in toothpaste, calcium carbonate and sodium bicarbonate, are minerals.
Caves with the National Natural Landmark (NNL) designation are some of the most fascinating of the thousands of caves around the world, and each one is unique. Caves’ special features are the product of various types of rock, their geologic setting, local climate, and time. This diversity in cave environments provides unique habitats for many different species of plants, animals, and other types of organisms. Each organism has developed specialized adaptations to survive in these cave environments.
Try this experiment to find out if you're a water waster.
In this activity you will use seeds to model mining valuable materials from rocks.
The United Nations includes clean water and sanitation in its sustainable development goals. Many places face severe water shortages. The Geoscientists Without Borders® (GWB) program supports teams to collaborate with communities to solve problems, including water shortages.
GWB scientists use geophysical techniques to find underground layers of sediments or rock that contain enough water to be drilled for water wells. These kinds of rock layers are called aquifers. In this activity you will build a model aquifer.
Students will become familiar with fire terminology, realize how fire can be used as a management tool, and better understand the factors that need to be considered when planning a prescribed burn.
Why is CO2 increasing in the atmosphere? Who is doing it? Many people think that CO2 is “pollution,” so that clean burning should be a way to eliminate greenhouse gas emissions. In this demonstration, we review basic chemistry (see illustration) to realize that producing CO2 is an inevitable product of burning any fossil fuel.
How sweet is this activity? It’s an introduction to the rock cycle using chocolate!
