Sea floor spreading forms the best evidence for continental drift. Critically discuss this statement. There is lots of evidence to support the theory of continental drift, including Harry Hess’s discovery of sea floor spreading theory. By using sonar, Hess found that oceans were shallower in the middle, allowing him to identify Mid Ocean Ridges. 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.
5. Compute a linear least-squares-fit of the calibration data and plot the resulting line on the same graph as the calibration data. Comment on the linearity of the pressure transducer and scannivalve. Part 3: Calibration of the Tunnel 1. Connect the micromanometer (calibrated in Part 2) across the wind-tunnel contraction in order to measure the static pressure drop.
Seawater is saturated with AgCl. If the [Cl-] in seawater is 0.53 mol/L, calculate the concentration of Ag+ ions in seawater. The Ksp of AgCl is 1.8(10-10 [3.40(10-10 M] 5. The solubility product constant for PbF2 is 3.7(10-8. Calculate the solubility of PbF2 in g/L.
This extreme pressure change makes the iso bars compact together creating fast moving winds and causing wind speeds to increase to even out the air pressure. 3. Describe the changes in central pressure and sustained wind speed between 29 and 30 August 2005? The air pressure from august 29th to august 30th changed from 904mbars to 985 mbars. While the air pressure increased the winds decrease as iso bars spread apart and wind is no longer moving at an abrupt pace.
Foredune and Second dune For the natural processes, Foredune and Second dune both are influenced by the seasonal wind, waves and parent rocks form Port Phillip Bay. During the flooding period from Port Phillip Bay and hardened into sedimentary rocks consequently, Foredune was formed as sediments washed from land by waves where eroded to form the underlying bedrock of the area (Gregory 1912) In terms of temporal scale, the pattern and shape of Seaford Beach influenced by seasonal alternations in dominant waves, which affected by two different directional wave during summer and winter months (Bird, 2011) There are gently curved beaches on coasts of Port Phillip Bay shaped by locally generated waves instead of received ocean swell (Figure 4) Although the beach materials, like sand and seashell, are removed seaward by storm waves, the coast outlines would maintain the smoothly curved shapes when the shape is established (Bird,
From this information, the percentage of salt verses water ions can be determined Ions are also produced in the liquid or solid state when salts interact with solvents (for example, water) to produce "solvated ions," which are more stable, for reasons involving a combination of energy and entropy changes as the ions move away from each other to interact with the liquid. These stabilized species are more commonly found in the environment at low temperatures. A common example is the ions present in seawater, which are derived from the dissolved salts. Procedure Obtain 250 mL beaker Weigh dry 250 mL beaker and record weight. Add 10mL of unknown salt and water solution.
Homework Unit 57 Section 7 1. What friction rate should be used to size a duct for a static pressure drop of 0.1 in wc if the duct has a total equivalent length of 150 ft? (57.10) 2. What size metal duct should be used to deliver 170 CFM with a pressure drop of 0.15 in wc if the total equivalent length of 130 ft? (57.10) 7 in.
Drop just enough pieces to rise the water level 0.5 mL. Record the starting and ending volumes. Now, re-mass the container and aluminum and record its value. Keep adding pieces of aluminum to the graduated cylinder, increasing the water level each time by 0.5 mL and recording it, and also re-mass the container and aluminum and recording that as well. Whenever you record the volume, record to the nearest 0.01mL.
