2. Lava Flows is the lava that slide down the side of the volcano. The dangers of hot lava meeting the surface are streams that resulted from the boiling of the salt water and the instantaneously change to a crystal. The water temperature where lava meets water is 30 -69. Volcanic Gases 1.
OPTION 2 SEMINAR BY DIEDRE JOHNSON The Water Cycle: The Water Cycle (also known as the hydrologic cycle) is the journey water takes as it circulates from the land to the sky and back again. The Sun's heat provides energy to evaporate water from the Earth's surface (oceans, lakes, etc.). Plants also lose water to the air (this is called transpiration). The water vapor eventually condenses, forming tiny droplets in clouds. When the clouds meet cool air over land, precipitation (rain, sleet, or snow) is triggered, and water returns to the land (or sea).
The magma that reached the sea bed due to weakness in the crust cooled quickly and formed a layer of basalt above the sediments (see diagram 1). Other magma intrusions
The Effects of Hydraulic fracturing on Air and Water Quality Introduction North America possesses immense natural gas reserves. Geologic formations such as the Marcellus shale in Pennsylvania, the Devanian shale in Ohio, and numerous others scattered around the nation are thought to hold enough natural gas to supply the nations energy needs, at current consumptions rates, for up to 27 years, with some estimates as long as one hundred years. (Urbina, 2011 ). Despite the abundance of the gas reserves, advanced drilling techniques are needed to extract the gas from the shale formations. The technique that it is primarily used is known as hydraulic fracturing.
Hydrologic Cycle The elements that combine to make water Hydrogen and oxygen are found in dust, grasses, and other stuff that formed Earth. The molten rock, called magma, which made up early Earth, contains water. Some water escaped from the magma and reaches the Atmosphere. As Earth cooled off, the water was able to settle on the surface and billions of liters later the oceans were formed. (5 points) |Score | | | 2.
He suggested that at the centre of oceans, molten material would rise from the Earth’s mantle, causing new sea floor to be created, pushing the ocean floor. He also suggested that there were ocean trenches where old sea floor would then go back into the mantle, and molten. He found that these ocean trenches, the deepest parts of the ocean, were very near continental plates. Hess theorized that the action of the sea floor spreading caused continents to move apart and so this being evidence for continental drift, showing why it happened. The evidence of sea floor spreading was further supported by Vine and Drummond, who studied the magnetic pattern of the sea floor.
Evidence of sea floor spreading can be found in the Atlantic, where it is believed that the North American and Eurasian plates are moving apart at a constructive plate margin. New land has been created due to the magma rising through a rift and cooling quickly on the surface, also creating a ridge of volcanoes called the Mid-Atlantic ridge. The
Where is the park located and what are its' dimensions? The base of the Cascade Range was constructed as the Earth's crust folded and uplifted, pushing the seas westward. Molten rock pushed toward the surface, creating both violent eruptions and forcing an incredible amount of lava upward through enormous cracks. Within the past 750,000 years these explosive eruptions built a string of volcanoes on this plateau base. This Cascade Range of volcanoes extends from Canada's Mount Garibaldi to Lassen Peak in northern California.
In the coal gasification process the air and stream are added to the raw coals then heat it to hundred degrees Fahrenheit. The carbon in the coal then react with the oxygen and the water then produces other gases such as carbon dioxide, carbon monoxide, hydrogen and methane. The carbon dioxide from the process is waste and can go to the atmosphere. The other gases can be burned or sent to the next process. Then the second process is after we get the processed and filtered coal, gas or water or carbon dioxide can be added to balance the amount of carbon monoxide and hydrogen.
Large amounts of methane and other poisonous gases released into the air from the gas wells contribute to heavy air pollution and global warming. Fracking has been linked to movement of radioactive materials and heavy metals from the underground layers of the earth to the surface through flow-back
