A. how do index contours let you know if the land you are viewing is increasing or decreasing in elevation? b. what would you expect to find in an area with ten evenly spaced contour lines?

a. Various index contour has an elevation connected with it. When you look at 2 contours, one will have a greater corresponding elevation. As you go from the moderate elevation to the higher elevation, you know that the land is rising in the direction toward the higher elevation. From the higher to the lower elevation, the land is decreasing (sloping downward, declining in elevation).

b. Evenly spaced contour lines indicate a steady slope, uphill or downhill. The lines on a map that force variations in elevation are called contour line. A contour line is a line on a map that joins points of equal elevation. They show how steep a land form is. A contour line also is a function of two variables in a curve which has a constant value.

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.

i would say it is
