Anh tries to find evidence that Earth changes over time due to natural processes. She sees a rock formation at a beach as shown in the diagram below. How does the picture relate to change by natural processes?
A. The rock formation was formed by tectonic plate movements over a long period of time.
B. The shape of the rock shows evidence of a canyon, which takes a long time to form.
C. The rock formation was formed by deposition over many years.
D. The shape of the rock was formed by weathering and erosion over a long period of time.

Find the steady-state temperature at the center of the plate = /2, = /2) for sums of w from n=1 to n=19 (only odd values). find the value of n for which the change in /2, /2) is less than 1% from the value at the previous n. at this point, we consider the solution converged. does the value of the temperature at the center seem reasonable? in this part, the values of x and y are constant scalar values. you should produce a plot of the value of n on the horizontal and the estimate of the temperature at the center of the plate on the vertical. b. using the value of n (or larger) that resulted in convergence in part (a), create a contourf plot of the temperature distribution across the entire plate. use enough spatial subdivisions to create a useful plot. comment on the results. hint: you need to determine what “x” and “y” values to use to make your t matrix. i recommend using a different number of x and y values. use enough x and y values so that the plot is “smooth”.
