K. The graph above shows how sea level has varied over the past 120,000 years (modified from Gurrola et al., 2014 based on data from Muhs et al., 2012). Using this graph, determine the elevation of sea level relative to modern sea level 45,000 years ago. Sea level 45,000 years ago: m[1] L. How much has the wave-cut terrace exposed in the beach cliffs been uplifted since it was formed 45,000 years? Be sure to account for both the change in sea level and its current height relative to sea level. m[1] M. Now calculate the rate of uplift of the Santa Barbara beach cliffs in both m per thousand years (m/ka) and mm per year ( mm/yr).
So, the solution to the given question is as follows:K. To calculate the elevation of the sea about the present-day sea level 45,000 years ago:Find the location on the x-axis where 45,000 years are plotted on the y-axis.Read the matching elevation value on the x-axis starting at that location.The available information indicates that the elevation 45,000 years ago was roughly -67 meters.
