According to the map, a seismic station in which city would be the first to detect seismic waves from an earthquake occurring in Mexico City? [pic] a. Chihuahua b. Houston c. Boulder [pic] d. Acapulco 12. Why does knowledge of Earth's interior come from seismic waves? [pic] a. They change speed and direction when they encounter different materials.
A seismometer permits seismologists to produce a map of the Planet’s inner surface. Another device that is used to utilize the measures of earthquakes is a Richter magnitude scale. This device provides figure to the quantity of seismic energy released during an earthquake. The Richter magnitude scale was created in 1935 by Charles Richter (www.geo.mtu.edu/UPSeis/intensity.html). Another way to measure the strength of an earthquake is to use the Mercalli scale.
Pick any three problems and find the difference. a. x2 –144 b. 64x2 –81 c. 36x2 –49y2 d. x4 –1 e. 81x4 –1 4. Factor a perfect square trinomial. Pick any two problems and factor each perfect square trinomial.
1. Describe the Rock Cycle. Be sure to include the different rock types and processes that occur within the cycle. Consider a hypothetical granite (igneous rock) and describe three possible pathways within the cycle (start each path with granite) The rock cycle helps us understand different parts of Earth System. It allows us to understand how sedimentary rocks, metamorphic rocks, and Igneous Rocks use one another to not only form the Rock Cycle, but also other processes that are important to our planet.
Geology 112 Earthquake or volcano essay and oral report directions Due date: February 25th (M/W) or 26th(T/TH) This purpose of this project is to understand the location, tectonic setting, explanation as to why event occurred, associated hazards in terms of cause, hazard definition, location hazard is expected to travel, damage in terms of structures or other property, fatalities and any mitigation methods in place or later addressed. The oral report will be presented by a team of 2-3 people. The individually written essay should cover the required information listed below. Essay directions: The 4-5 page essay should be double-spaced with one inch margins on all sides and fully cited using a standard referencing technique.
b. Use a different symbol for each ball. c. Make a key so that you are able to tell the plots apart. Answer: (3 points) Score 6. Did your data agree with your hypotheses?
Pre-lab Questions Answer these questions: 1. What factors could affect an impact crater's shape and size? 2. Describe how varying each of these factors will alter the craters and explain how you could test these hypothesis. 3.
The distance between the forces is given by the Coulombs law through the use of the formula F=kq1q2/r2.0.1newtons = 8.99*109*3.2*10-6*7.7*10-7/r2 R= 555.78 Answer to question 3 • Potential difference between the two plates is equal to velocity which is equal to 6.0*106m/s • Force = mass *acceleration = 1.4*10-13*6.0*106 = -8254 nektons The speed of the particles are computed by the formula V=ED. This is equal to 8.5*10-6*0.15. This is equal to 84.1 Answer to question 4 Voltage = current *resistance. This implies that in this case while V is 5.0 and resistance is 1.0*103, current will be equal to 5/1.0*103, = 500 amps B the direction of the conventional current provides the electric charge movement from the positive side of the battery to its negative side as in indicated in the diagram below Answer to question 5 • This section focuses on the equivalent resistance of a circuit. The equivalent resistance will be equal to (5.0*102+1.00*103)2.
What do earthquake swarms indicate? (page 94, para 2 to page 95) Earthquake swarms indicate that new fractures were forming. Swarms can be used as an early indication that magma from a storage zone is being injected into the rifts were these new fractures are happening. 3. What is "summit deflation"?
HSC Chemistry Assessment task 1 Nuclear Chemistry Research report 1. Distinguish between stable and radioactive isotopes and describe the conditions which a nucleus is unstable. To understand if an element is stable we first must understand what stability is. The stability of the nucleus is directly related to the strength of the forces that hold the nuclear particles together. These protons and neutrons of the nucleus are called nucleons.
