local environment you wish to sample for bacteria. 2. Obtain a sterile TSA (Trypticase soy agar) plate. Keep it sterile, do not open yet! 3. Label the bottom of the plate with the following: - students initials or names - type of exposure - date of exposure 4. Expose the plate. Do not open the plate longer than is necessary for your exposure. 5. Cover and turn upside down. Place on the tray

What's Involved In Having One Of Your Teeth Pulled There are times when pulling one of your teeth might be the best way to deal with a dental problem. Your dentist has two ways of doing a dental extraction. One is a simple extraction that pulls the tooth out and the other is a surgical extraction that involves cutting into your gum to remove the tooth. A simple extraction may be all that's needed if you're having a tooth pulled because it is injured, decayed, or infected. Here's what you can expect

Causes What are the causes of the hazard? Volcanoes are formed when Magma rises from the upper mantle towards the Earth's surface. This process can be assisted by seismic activity or a variety of thermal driven phenomenon. As early as November 1984, increased levels in seismic activity were observed by geologist near Nevado Del Ruiz. Due to this increased activity, geologist became more observant of events, even if minor. In November 1985, the volcano began releasing gasses that were rich in sulfur

Cold seeps and hydrothermal vents are localities where subsurface fluid leak from the seafloor. The main difference between cold seeps and hydrothermal vents is the temperature of the emanating fluid. The seepage emitted from cold seeps is the same temperature as the surrounding seawater, whereas hydrothermal vents radiate much hotter water. The hydrocarbons that emanate from cold seeps are usually methane, but could also be ethane, propane, or oil. Cold seeps and hydrothermal vents have a community

Name:___________________________ Date:___________________ Period:________ How Can Volcanic Landforms Form Far Away From Plate Boundaries? 1) What are the places where islands are formed far away from a plate boundary (ex: Hawaiian Islands)? A) offset B) hot spot C) volcanic island arc 2) When magma rises from inside the Earth through the lithosphere to the surface thanks to a hot spot, what will form when the lava would build up? A) volcanic island B) ocean floor C) undersea volcano 3)

Mount Tambora and its Destruction Mount Tambora is a stratovolcano and is located on Sumbawa Island, Indonesia and is still currently an active volcano. The volcano was 14,000 feet high and was the tallest peak in Indonesia until its eruption in 1815 which caused the volcano mountain to decrease to 9,354 feet. The volcano is sitting on a subduction zone and is surrounded by an oceanic crust. There has been several eruptions from this particular volcano but the most destructive and memorable eruption

Researchers at the University of Utah have combined seismograph information from distant seismology stations regarding the levels of magma beneath the volcanoes located at Yellow Stone National Park. Seismologists were able to take a deeper look into the volcano and found that there is a significantly large magma reservoir beneath the magma chamber. This newly found body of magma(reservoir) is more than four times the size than the body of magma that lies above it. This new information and its finding

form during shortening of the crust, but the fault’s slope is gentle (<30 degrees) D) On a strike-slip fault, one block slides laterally past another, so no vertical displacement takes place E) As oceanic plates spread apart at mid oceanic ridges, they must slide past other plates, along transform faults 3. What is the lithosphere and asthenosphere? (defined by strength) The lithosphere is a zone of strength, where if you apply enough stress, it will break causing an earthquake. The lithosphere

Plate margins are involved in the Earth as a major provider to many of Earth’s geological formations. These plates are approximately 100 kilometers thick, which is very thin compared to the largeness of a 6000-kilometer radius of the Earth. Most major plates include both continental crust and oceanic crust. An earthquake is the shaking of the Earth’s crust due to a sudden release of energy. They are caused by stress that builds up between two lithospheric plates. When two plates slide next

Lorinda White Feb-09-15 PHS120 Essay 2 1. Cite the lines of evidence Alfred Wegener used to support his idea of continental drift. Why did scientists doubt that continents drifted? Alfred Wegner’s evidence was the way the continents fit together like a jigsaw puzzle, fossils of the same prehistoric species were found where continental drift was expected to be (for example fossils of the same species were found in western Africa and South America), matching mountain ranges, and land features
