, SCSC 301 - Exam 1 Questions and
Answers (Latest Update 2025)
What about soils used for buildings and roads? - Correct
Answer ✅o Soils differ in their bearing strength,
compressibility, shear strength, and stability
What about soils used for habitat? - Correct Answer ✅A
handful of soil may contain billions of organisms. Example is
pores filled with water having roundworms, diatom, and
rotifers.
What about purification of water and regulator of water
supplies? - Correct Answer ✅Most rain travels through or
over the soil. Soil slows water flow. Soil binds and detoxifies
many pollutants, thus purifying water as it moves toward
water bodies.
What about Recycling system for nutrients and organic
wastes - Correct Answer ✅Animal and plant wastes
become Humus, CO2, and nutrients available to plants.
Which elements are an essential plant nutrient? - Correct
Answer ✅- Macronutrients
