A bar graph titled Global Trade (Percent of G D P). The x-axis is labeled Year from 1988 to 2013. The y-axis is labeled Percent of G D P from 0 to 70. 1988 and 1993 were under 40 percent. 1998 and 2003 were over 40 percent. 2008 and 2013 were almost 60 percent. Which statement is supported by information in the graph? Trade between nations steadily decreased between 1988 and 2013. Trade between nations steadily increased between 1988 and 2013. Trade between nations increased between 1988 and 2003, and then decreased. Trade between nations decreased between 1988 and 2003, and then increased.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
