During the May Day holiday this year, Mr. Wang, who was traveling, climbed a mountain to a place and determined his location through GPS positioning (pictured). Reading pictures

(1) (60°W, 30°S) West

(2) Short days and long nights _____ around June 22

(3) Southwest Conference

Test question analysis:

(1) Reading the map shows that the longitude and latitude of A is (60°W, 30°S), it can be judged that location A is located in the Western Hemisphere.

(2) The town where Mr. Wang stayed is located in the southern hemisphere. During the May Day holiday, the sun shines directly on the northern hemisphere. The days in the southern hemisphere are shorter and the nights are longer, and the day length will become shorter. This changing trend will continue until Around June 22nd.

(3) According to the latitude and longitude grid, place A is located southwest of place B. It can be seen from the contour diagram that from point A to point B, we pass through a valley, so we may encounter a river.

Comments: The distribution of contour lines can reflect the surface form. A closed contour line with a high middle and low sides is a mountain top, and a low middle with high sides is a basin. When contour lines are curved, you can use the formula "high convex to be low, convex low to be high" to help remember valleys and ridges. The convex lows are ridges, which are watersheds, and the convex heights are valleys, where rivers may develop and flow to low places; the terrain where the contour lines intersect is steep cliffs; the dense contour lines reflect larger slopes and faster river flow speeds.
