Tossup

Changes in this quantity are associated with changes in radar reflectivity in a form of interferometry whose control variables are “persistent scatterers.” Measurements of this quantity standardized to the GTOPO30 (“G-topo-thirty”) system have since been improved by the ASTER instrument. (-5[1])Techniques like IfSAR (“IF-sar”) and InSAR (10[1])(“IN-sar”) are used to obtain image representations (-5[1])of this quantity called DEMs (-5[1])(“D-E-M’s”). Temperature gradients (10[1])relative to this quantity (10[1])in dry and moist air parcels define the (10[1])adiabatic (10[1])lapse (10[1])rate. (10[7]-5[2])High values (10[1]-5[1])of latitude (10[1]-5[1])and this quantity (10[1])form the “tree line” (10[2])of a habitat. (10[4]-5[3])Constant (10[7])values of this quantity (10[2]-5[1])are represented (10[2])by contour lines (10[4])on (10[1])topographic (10[4])maps. (10[4]-5[1])For 10 points, (10[1])what quantity (10[3])is defined as (-5[1])zero at sea level? (10[3])■END■ (10[5])
