- Greece’s 3,000 islands and 15,000 kilometers (9,300 miles) of coastline highlight this image acquired on November 11, 2005. The rich texture produced by the topographic variation in this image reveal that it is the most mountainous of all the European countries, comprising about 80% of the country’s land surface. These mountains are the product of plate tectonics: the Eurasian plate, stretching from the Eastern portion of Siberia into the middle of the Atlantic Ocean, is converging with the African plate. The region is also known for its volcanic activity; the so-called Hellenic Arc of islands, which stretch from the eastern of Greece to western Turkey, is the result of subduction of the African plate under a portion of the Eurasian plate. This portion, or microplate, is called the Aegan plate is actually moving in a different direction than the rest of the Eurasia plate because it is being pushed by the Turkish microplate as well as the African plate. The most famous of these volcanoes is Santorini, which last erupted in 1950. It erupted in 1600 B.C., obliterating the city of Akroteri, an event which may have spawned the legend of city sinking under the ocean – Atlantis.
- The Turkish Microplate is also known as the Anatolian Sub-Plate.
- Depression (mood) (Wikipedia)
Depression is a mental state of low mood and aversion to activity. It affects more than 280 million people of all ages (about 3.5% of the global population). Depression affects a person’s thoughts, behavior, feelings, and sense of well-being. Depressed people often experience loss of motivation or interest in, or reduced pleasure or joy from, experiences that would normally bring them pleasure or joy. Depressed mood is a symptom of some mood disorders such as major depressive disorder and dysthymia; it is a normal temporary reaction to life events, such as the loss of a loved one; and it is also a symptom of some physical diseases and a side effect of some drugs and medical treatments. It may feature sadness, difficulty in thinking and concentration and a significant increase or decrease in appetite and time spent sleeping. People experiencing depression may have feelings of dejection or hopelessness and may experience suicidal thoughts. It can either be short term or long term.
