- Levant (Wikipedia)
The Levant (/ləˈvænt/ lə-VANT) is an approximate historical geographical term referring to a large area in the Eastern Mediterranean region of West Asia and core territory of the political term Middle East. In its narrowest sense, which is in use today in archaeology and other cultural contexts, it is equivalent to Cyprus and a stretch of land bordering the Mediterranean Sea in western Asia: i.e. the historical region of Syria (“Greater Syria”), which includes present-day Israel, Jordan, Lebanon, Syria, the Palestinian territories and most of Turkey southwest of the middle Euphrates. Its overwhelming characteristic is that it represents the land bridge between Africa and Eurasia. In its widest historical sense, the Levant included all of the Eastern Mediterranean with its islands; that is, it included all of the countries along the Eastern Mediterranean shores, extending from Greece in Southern Europe to Cyrenaica, Eastern Libya in Northern Africa.
- Plucking (Wikipedia)
Plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the weathering and erosion of pieces of bedrock, especially large “joint blocks”. This occurs in a type of glacier called a “valley glacier”. As a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock. The freezing and thawing action of the ice enlarges, widens, or causes further cracks in the bedrock as it changes volume across the ice/water phase transition (a form of hydraulic wedging), gradually loosening the rock between the joints. This produces large pieces of rock called joint blocks. Eventually these joint blocks come loose and become trapped in the glacier.
