Answer:
St. Petersburg is located on the Pinellas Peninsula in southernmost Pinellas County. It is surrounded by the Gulf of Mexico to the west and Tampa Bay to the east. To the north, the city borders Clearwater. The 345 miles of shoreline around the peninsula include the resort communities of Clearwater Beach, Dunedin, Indian Rocks Beach, Redington/Bellaire Beach, Madeira Beach, St. Petersburg, St. Pete Beach, Safety Harbor, Tarpon Springs, and Treasure Island. The Sunshine Skyway bridge spans Tampa Bay to connect St. Petersburg with Manatee County to the south. More than 20 barrier islands buffer the Pinellas Peninsula from the Gulf of Mexico, resulting in a calm surf ideal for family water activities.
Explanation:
The correct answer is - Tethys Ocean.
The Tethys Ocean was an ocean that was situated between the European and African continents, through what is now the Middle East and parts of Central Asia, and the northern half of the Indian Ocean. Because of the geologic activities, mainly the movement of the Indian plate towards Asia, and the Alpine orogenesis, the ocean was becoming smaller and smaller, and it started to be divided into smaller pieces, until it totally disappeared. One of the remains of this ocean is the largest lake in the world, the Caspian Lake, often referred to as Caspian Sea, and it can easily be seen that this body of water was once part of a much bigger body of water with saline water, because it itself has saline waters.
