Calculate the Rate of Seafloor Spreading from the Age of the Seafloor
TECTONIC PLATES ON EARTH move relative to one another, diverging along mid-ocean ridges, converging along subduction zones, and sliding past one another on transform faults. Relative movement of the plates causes most earthquakes and volcanic eruptions and explains the present distribution of continents. A key aspect of plate tectonics involves seafloor spreading, where two plates move apart relative to one another, generating new oceanic crust in the process.
Figure 1 shows the age of seafloor as determined by the measuring of the magnetism and assigning ages by comparing the magnetic patterns to the geomagnetic timescale. Ages
are also determined by collecting and dating samples of rocks and sediment from the seafloor. The youngest seafloor is colored orange, intermediate ages are yellow and green, and the oldest is blue and purple. No seafloor is older than 200 m.y. old because older seafloor has been subducted into the mantle at some point in the past.
Mid-ocean ridges are represented by the dark lines within the most recently formed seafloor (shown in orange). Note how the color patterns representing the age of seafloor are symmetrical with respect to most mid-ocean ridges, such as those in the Atlantic Ocean. The age patterns are locally truncated in the Pacific Ocean where subduction has consumed the eastern part of so e plates. Examine the patterns in each ocean.
Analysis and communication
1. Can you tell which ridge segments are spreading more rapidly than others? (Write a complete answer by using subjects, verbs and appropriate explanation)
We can determine the rate of seafloor spreading if we know the width of oceanic crust that has been generated in a specific length of time. Width divided by time is the rate of spreading:
Spreading Rate = Width of Oceanic Crust / Time During Which That Crust Formed
For example, if a width of a belt of oceanic crust is 80 km, and it took 10 m.y. to form that crust, the equation is:
Spreading Rate = 80km wide/10m.y. duration = 80 km/m.y.
For seafloor spreading, we generally refer to rates in centimeters per year, so we need to convert our units from kilometers (km) to centimeters (cm) and from million years (m.y) to years (y). To convert km to cm:
1 km = 1km · 1,000 m/1km · 100cm/m = 100,000cm
so we multiply km by 100,000 (1 x 105) to get centimeters. To convert millions of years into years, we multiply our value for m.y. by a million (1,000,000 or 1 x 106). The spreading rate equation becomes:
Spreading Rate (cm/yr) = [width (km) · 100,000 cm/km]/[Duration (m.y.) · 1,000,000 (yr/m.y.)]
When you cancel out the zeros (100,000 over 1,000,000) there is one zero left over in the denominator, so to get from km/m.y. to cm/yr, we simply have to divide by 10. Thus, the total process is:
1 – measure the width in kilometers;
2 – note how long it took that oceanic crust to be formed (the duration);
3 – divide the width by the duration;
4 – divide by 10 to get cm/yr.
For our example the result is 8 cm/yr, a typical rate.
Spreading Rate = 80km wide/10m.y. duration = (80 km/m.y.)/10 = 8.0 cm/yr
Representation and manipulation
On the map in Figure 1 there are thick lines across mid-ocean ridges in the Atlantic Ocean (A-D) and Pacific Ocean (E and F).
Table 1 lists widths represented by each line and the duration over which the oceanic crust within that width was formed. Calculate the spreading rate in cm/yr for each line, show your calculations and write your answers in the table.
Table 1. Spreading rates of the oceanic floor
Line Width
(km) Duration
(m.y) Spreading Rate (cm/yr)
A 1050 55
B 5850 180
C 4530 120
D 6130 135
E 3350 20
F 5420 100
2. My calculations:
Analysis, assumptions and communication
3. Which part of the Atlantic Ocean opened first and is that segment’s spreading rate faster slower or the same as those for the other three lines across the Atlantic? When writing your answer use appropriate grammar and use the data in the table to support your statements.
4. How do the two spreading rates for lines C and D compare? Can you explain the difference in rates and why the age widths (and ocean) widen to the south? When writing your answer use appropriate grammar and use the data in the table to support your statements.
5. How do the spreading rates in the Atlantic Ocean compare with those in the Pacific Ocean? When writing your answer use appropriate grammar and use the data in the table to support your statements.
6. The correctness of this exercise relies on a series of assumptions. Order them by the most (1) to the least (5) important:
[_] The endpoint of every line in Figure 1 at some time in the past were in the same location
[_] The spreading rate that we compute is an average between burst of higher activity and dormant phases
[_] The same geologic processes as today occurred millions of years ago
[_] Dating method of the ocean seafloor are reliable
[_] The location of plate boundaries is accurate
Interpretation, analysis and communication
– Look carefully at the location and distribution of colors along the line F
– Look carefully at the location and distribution of colors along the line C
One line is in the northern part of the Pacific Ocean and the other line is in the Atlantic.
7. Use two concept sketches to show the geometry of plate boundaries along line F and line C. Can you identify the spreading centers, the location of a subduction zone and passive margins? Remember to include labels and short sentences explaining the key geologic processes.
[Take pictures of your sketches and insert them on this document. Add pages as needed, make sure all the labels and sentences are clearly readable. If you prefer you can draw on a printed version of this file.]

ECON 202 University of Massachusetts Dartmouth Macroeconomics Theory Questions Economics Assignment Help
I’m working on a economics question and need support to help me study.
Macroeconomics theory – Econ 202 – 2 questions
Question 1: Over recent decades in the U.S. economy there have been a set of changes that,
together, have reduced worker bargaining power (reduced ‘z’). These changes include declining
unionization rates and a declining inflation-adjusted minimum wage. (15 points)
a. Use the baseline version of the labor market model (i.e. in which the markup depends
only on the degree of competition between firms and not on relative bargaining power) to
graphically analyze the effect of these changes in labor market institutions on the natural
rate of unemployment and real wages.
Because our labor market model is based on the relative bargaining power of workers and
employers, a reasonable extension of our model also allows the mark-up to change when
bargaining power changes.
b. If the mark-up also depends on bargaining power, does the mark-up increase or decrease
when worker bargaining power falls? Why?
c. In this case, show the effect of declining unionization rates using the graphical labor
market model. What happens to real wages and unemployment? Explain briefly.
d. Compare your answers to (a) and (c). Which version of the model do you find more
convincing and why? (Explain in 1-2 sentences).
Question 2: Describing the relationships in the Phillips curve (10 points)
Consider the following general form of the Phillips curve:
π” = π”
$ + (m + z) − αu”
a. If there is an increase in the markup, what happens to inflation? Explain why.
b. If there is an increase in unemployment, what happens to inflation? Explain why.
Question 3: Anchored versus adaptive expectations and the Phillips curve (15 points)
Suppose the Phillips curve is given by:
�. = �.
/ + 0.1 − 2�.
a. What is the natural rate of unemployment?
Assume that inflationary expectations are anchored at 0%. Suppose that the rate of
unemployment was initially equal to the natural rate. In year t, the authorities decide to bring the
unemployment rate down to 3% and hold it there forever.
b. What is the rate of inflation in years t, t + 1, t + 2 and t + 5?
c. Do you think that, in year t+5, people will still expect inflation to be 0%? Why or why
not? (Hint: think about how people are likely to form expectations of inflation).
Now suppose that in year t + 6 inflationary expectations become adaptive. Suppose that the
government is still determined to keep u at 3% forever.
d. What is the inflation rate in years t + 6, and t + 7?
e. Continue to assume inflationary expectations are adaptive. What happens to inflation
when unemployment is kept below the natural rate of unemployment? What happens to
inflation when unemployment is kept at the natural rate of unemployment?

AAAS 288A Abram Friedman Occupational Center Week 1 Autoethnography Fieldnotes Journal Writing Assignment Help
I’m working on a health & medical writing question and need support to help me study.
Assignment Summary
- Five 600-word entries in a fieldnotes journal
- Content focuses on everyday “autoethnographic” observations related to the provided prompts
- Writing style is open to student choice; illustrations, etc., welcome
- Must meet provided Minimum Requirements to be accepted for credit
- Grading based on a provided rubric
- Final due date on December 10
Assignment Overview
Each week, students will write fieldnotes observing the role of their online activities in their own lives. These fieldnotes will be “autoethnographic,” which is a phrase that combines “auto” and “ethnographic.” “Auto” means “self,” like in “autobiography.” “Ethnographic” means, literally, “culture-writing”; ethnography is a genre of qualitative social science writing central to cultural anthropology, sociology, education research, and many other fields. We can gloss autoethnography as self-culture-writing. One of my favorite definitions of autoethnography describes it as “an approach to research and writing that seeks to describe and systematically analyze (graphy) personal experience (auto) in order to understand cultural experience (ethno)” (Ellis, Adams, and Bochner 2011, 273). I like how this definition interprets the “writing” part of the word as description and systematic analysis. I have coordinated the fieldnote prompts with the ethnographic readings (as well as the wellness activities) to help you produce a description and systematic analysis through your autoethnography. Our ultimate goal is to systematically analyze our own personal experiences online in order to understand the broader cultural experiences characteristic of the current moment.
OBJECTIVE
There are two main goals of this assignment. The first goal is to become more aware of the cultural aspects of our own online activities. The second goal is to integrate the concepts and evidence from the ethnographic readings through comparison with our own cultural milieu online. A tertiary goal is to provide students an introductory experience of ethnographic writing and analysis.
