Example 1: North Anatolian Fault Zone in the sea of Marmara
• Bouguer anomalies that are negative over high areas and positive over oceans. •Near sea level, the average is close to zero.• The negative Bouguer anomalies areas due to the excess of low density material at depth in mountainous regions when compared to rocks at depth in areas of low relief near sea level.

Use the online tool for making a gravity map from the site http://www.itismolinari.mi.it/Gravity.htm.Make your gravity map and compare changes in the gravity to changes through regions of major tectonics? What is the gravity through the areas:
a) Red Sea b) Dead Sea Fault c) Iranian Sea d) Gulf of Aqaba e) Zagros Thrust Fold
