Name: Learning GOAL You will interpret coastal landforms and use them to distinguish between emergent an coastlines. A Refer to the photograph of the Po Delta, Italy (Fig. 16.4), During Etruscan times around 600 BC, the city of Adria was a ba Scaport on the coastline at the mouth of the Po River. Adria was so important that the Adriatic Sea was named after it. The F River has continued to deposit sediment at its mouth and has extended its delta far bevond Adria, which is no longer located on the coastline. 1. What has been the average annual rate (in cm/yr) at which the Po Delta has extended toward the Adriatic Sea since Adria was a thriving seaport on the coast? Show your work. 2. Based on the average annual rate that you just calculated, how many centimeters does the leading edge of the Po Delta move seaward during the lifetime of someone who lives to be 60 years old? Show your work.

Please help me answer section A

Learning You will to submergent Activity 16.2 Introduction to Coastlines Date: Name: Course/Section: Learning GOAL You will interpret coastal landforms and use them to distinguish between emergent and subnior coastlines. A Refer to the photograph of the Po Delta, Italy (Fig. 16.4), During Etruscan times around 600 BC, the city of Adria Was a ba seaport on the coastline at the mouth of the Po River. Adria was so important that the Adriatic Sea was named after 1l. The o River has continued to deposit sediment at its mouth and has extended its delta far beyond Adria, which is no longer locatea on the coastline. 1. What has been the average annual rate (in cm/yr) at which the Po Delta has extended toward the Adriatic Sea since Adria was a thriving seaport on the coast? Show your work. 2. Based on the average annual rate that you just calculated, how many centimeters does the leading edge of the Po Delta move seaward during the lifetime of someone who lives to be 60 years old? Show your work. 3. REFLECT & DISCUSS Sea level is rising and submerging coastlines adjacent to the Po Delta, and yet the delta is still extending out into the Adriatic Sea. Why? B Refer to the map and photographs of St. Catherines Island, Georgia (Fig. 16.5). Note that on the southwestern and east-central parts of the island there are large areas of salt marsh (Fig. 16.5A). Living salt marsh plants are present there as shown on the right (west) in Figs. 16.5B and 16.5C. A sandy beach that occurs on the east side of the island can be seen in Figs. 16.5B and 16.5C bounded on its seaward side (left) by another strip of marsh mud. This is a relict salt marsh consisting of mud from an ancient salt marsh that is eroding along the coastline. 1. What type of sediment is probably present beneath the beach sands in Figs. 16.5B and 16.5C? (3) 2. Explain how you think the beach sands were deposited landward of the relict marsh mud. 12c022 3. Portions of the living salt marsh wetland in Fig. 16.5C recently have been buried by white sand that was deposited from storm waves that crashed over the beach and sand dunes. What is the name given to this type of sand body?
