Answer to Problem 1FQ

Major causes for the climate changes along the 40ºS latitude line from west to east across South America are the westerlies flowing out of the subtropical high and bringing moisture from the Pacific Ocean to the west coastal portion of the parallel and the rain shadow effect of the Andes to the east.

Explanation of Solution

From the image, the areas of savanna climate are located adjacent to the rainforest climates of South America. Chile is located along the west of the 40ºS latitude line of the South America. It lies between the Andes in the east and Pacific Ocean in the west. Chile experiences Marine west coast climate receiving a year-round ample precipitation as the west coast location is under the influence of westerlies and has mild to cool summers.

Moving to the east of the latitude line, the highland locations of the Andes or Andean Mountains exist there. Andean Mountains are the longest continental mountain range in the world that forms a continuous highland along the western edge of South America. The Andes experiences two different climatic conditions due to the location of pacific ocean to one side and desert regions on the other. As local topography being the most important factor for receiving precipitation, Chilean Andes experiences wet climatic condition as it parallels the western coast of South America by receiving ample precipitation, both cyclonic and orographic, falls on the windward side of the mountains. The Andean mountains in Argentina experiences dry climates as it reaches 40°S due to the leeward effect of the mountain barrier.

Moving further to the east of the latitude line, semi-arid climatic conditions exist in Argentina. Argentina is bordered by Chile in east and Uruguay on the west. Steppe (semi-arid) climate regions have slightly higher precipitation totals than deserts and can support grassland vegetation. The semiarid climates are transitional zones between the humid climates and the deserts.

Arid regions typically have a central core of desert climate, surrounded on the boundaries by transition zones of semi-arid steppe climates. The arid conditions within continental interiors are because of their remote locations from moisture-carrying winds. These arid lands include the cold-winter deserts of South America. The dry conditions of Argentina are due to the mountain barriers (Andes) which block the migration of rain-bearing air masses from the Pacific Ocean in the west. Hence, the rain-shadow conditions help to clarify the Patagonian Desert of Argentina.

due today at 2pm, the problem have been done already, is there anyway you can draw the diagrams i was supposed to for this because I am confused on how to draw them
1. Calculate the elevation of the water table at each well location and write the approximate elevation on the line next to each well. Next, use a colored pencil to draw smooth 10-foot contours that show the shape of the water table. (Start with the 1160-foot contour.) Use a pencil of a different color to draw arrows on the map to indicate the direction of the slope of the water table. a. Toward which direction (downward) does the water table slope? b. Referring to the site of the proposed water well, at approximately what depth below the surface should the proposed well intersect the water table? 2. Assume that a dye was put into well A on May 10, 2017, and detected in well B on May 25, 2018. What was the rate of groundwater movement between the two wells, in centimeters per day? (Hint: Convert feet to centimeters.)Velocity:_____________centimeters per day
