What are the sediment types and thickness observed at each
location, View the legend for identifying the different lithologies
and sediment types by color? What features in the
terrestrial/marine environment are impacting the distribution of
sediments? Compare and contrast the shelf, slope, and rise from
these three sites and explain what processes and features account
for the observed variations. (7.5 pts.)

Location 1: From the mouth of the Hudson River (NY) to the southeast. a. Calculate the slopes (rise/run) of the Shelf, Slope and Rise along the following traverse: Lat. 40.5° Lon. -74.0° to Lat. 36.7° Lon. -66.0°. Please show all work for full credit. (0.5 pt. per calculation; total of 1.5 pts.) Rise (m) Run (m) Slope= Rise/Run Shelf 100 200,000 100/200,000= 0.0005 Slope 2200 55,000 2200/55,000=0.040 Rise 300 30,000 300/30,000= 0.010 b. Convert ach calculated slope to an angle. (0.5 pt. per conversion; 1.5 pts.) Slope in degree of shelf= tan-¹(0.0005)= 0.028° Slope in degree of slope= tan¹(0.04)= 2.29⁰ Slope in degree of rise= tan-¹(0.01)= 0.573⁰ c. Compare and contrast how the angles change from the shelf to slope to rise. (1.5 pts.) Hence, we find that the angle increases sharply from shelf to slope and then decreases from slope to rise. Thus, the slope is characterized by maximum slope and shelf with minimum. d. Copy the profile window into your assignment. Annotate the diagram with the locations of the shelf, slope, rise, and any visible submarine canyons and seamounts. Submit your annotated diagram with the rest of your completed homework. Use a figure caption to describe the profile. (1 pt.) shelf GMRT Grid Version 4.0 -0 100 200 700 800 Rise 300 Seamounts 400 Distance, km 500 600
