CUP OF LAVA Camille Sager Darielle Donato Eric Valerio I. Introduction Salt‚ also known as common salt‚ table salt‚ rock salt‚ or halite‚ is an ionic compound with the formula NaCl (sodium+chloride). Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. As the major ingredient in edible salt‚ it is commonly used as a condiment and food preservative. Because of its importance to survival‚ salt has often

Lava Lamp Science Investigatory Project Submitted by: Keanu Kent B. Gargar IV – St. Ezekiel 10/7/13 Introduction A lava lamp (or Astro lamp) is a decorative novelty item‚ invented by British accountant Edward Craven-Walker in 1963. The lamp contains blobs of colored wax inside a glass vessel filled with clear liquid; the wax rises and falls as its density changes due to heating from an incandescent light bulb underneath the vessel. The appearance of the wax is suggestive

volcano? Vents‚ lava‚ magma chamber‚ and ash 6. What is the difference between an explosive and a non-explosive eruption? Nonexplosive Eruptions * Most common type * Laval flows from them calmly. (can be huge amount) Explosive Eruptions * Rarer than nonexplosive eruptions * Are very destructive as pyroclastic materials are flung into the air. 7. What materials erupt from a volcano? Pyroclastic materials and lava. Types of lava: Aa * Lava pours out quickly

When mafic lava breaks through fissures in the continental crust‚ which of the following often results? a. lava plateaus b. composite volcanoes c. lava domes d. pyroclastic sheets 5. Which scenario is associated with mafic magma? a. hot‚ fluid lava that forms a shield volcano b. hot‚ fluid lava that forms a stratovolcano c. an explosive eruption that ejects pyroclastic materials d. cool‚ viscous

of a lava chamber and a plug‚ which will cause a great explosion if blown. The sides are made of layered tephra (rock fragments and particles) and dried lava. Strato Volcano’s have a thicker lava similar to putting a cap on a soda bottle and shaking it up. When the pressure becomes too immense‚ the plug releases and causes a heavy eruption which includes a pyroclastic flow. When the emitted Lava collects on the sides of the volcano it backs up and forms the steep. A shield Volcano’s lava is thinner

of highly viscous lavas. They are sometimes formed within the crater of a previous volcanic eruption (as in Mount Saint Helens)‚ but can also form independently‚ as in the case of Lassen Peak. Like stratovolcanoes‚ they can produce violent‚ explosive eruptions‚ but their lavas generally do not flow far from the originating vent. Cryptodomes Cryptodomes are formed when viscous lava forces its way up and causes a bulge. The 1980 eruption of Mount St. Helens was an example. Lava was under great pressure

form of lava (most commonly molten basalt) is potential of shaping different landforms on earth crust. The most common landforms that are results of volcanic activity include cones‚ craters‚ calderas‚ domes etc. This article gives a description of these volcanic landforms. SHIELD VOLCANOES- These are characterised by gentle upper slopes. The slope varies from only 5 degrees to 10 degrees. The shield volcanoes are made up of mainly thin lava flows around central vent.

scoria volcanoes‚ marr volcanoes‚ composite volcanoes‚ shield volcanoes and fissure volcanoes are unevenly distributed in the area‚ with a few youngest ones in the state such as Mt. Napier. Other volcanic features such as stony rises‚ lava tubes/caves‚ tumulis‚ lava canals and natural bridges can all be found in this area. The volcanoes are very significant to residents in the local region‚ as it bring fertile soil for agriculture and opportunities for other industries such as stone cutting or
