Soil and Environmental Conservation Quiz

Soil comprises minerals, organic matter, water, and air.

Erosion refers to the gradual process of soil and rock removal by natural agents like water, wind, or ice.

Humus is the dark organic material formed by the decomposition of plant and animal matter in soil.

Clay soil consists of very fine particles, smaller than those of sandy or loamy soils.

Windbreaks, like trees or shrubs planted along field edges, reduce wind speed and minimize soil erosion.

Topsoil is the upper layer of soil where plant roots grow and most biological activity takes place.

Crop rotation involves alternating crops in a particular field over different seasons to maintain soil fertility and reduce erosion.

Terracing involves creating flat platforms on steep slopes to minimize erosion and conserve soil.

Most plants thrive in soil with a pH range between 6 and 7.

Deforestation, the removal of trees and vegetation, exacerbates soil erosion rather than conserving it.

Conservation tillage minimizes soil disturbance, maintains crop residue cover, and enhances soil health.

Percolation is the movement of water through the soil's pores and interstices.

Industrial waste, including chemicals and pollutants, is a major contributor to soil pollution.

Excessive irrigation leads to the accumulation of salts in the soil, causing salinization.

Subsoil is the layer beneath topsoil where leaching affects nutrient movement.

Strip mining involves the removal of soil layers, exacerbating soil degradation rather than remediating it.

Soil horizons include O, A, E, B, and C horizons, but there's no X horizon in standard soil classification.
