Which properties describe pedocal, a type of soil common in the western united states?

a. dry, light gray-brown in color, and abundant in calcite

b. damp, reddish-brown in color, and rich in clay

c. wet, orange or red in color, and poor in calcite

A. dry, light gray-brown in color, and abundant in calcite.

Pedocal soils found in the western United States, are exposed to dry, warm climates and receives very low amount of rainfall. They exhibit high amount of calcium carbonate and sulfate minerals, because of the composition and environmental exposure they are light gray brown in color and dry.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

answer; i believe the correct answer is (sporophyte);
