Sustainable Energy Exam Questions and
Answers with Verified Solutions | Latest
Updated 2026
What are the different soil Soil horizons are distinct layers in the soil
horizons? profile,
including the O horizon (organic matter), A
horizon
(topsoil), E horizon (eluviation layer), B
horizon
(subsoil), and C horizon (parent material),
each
differing in composition and
characteristics.
What are the differences between Sustainable agriculture focuses on
sustainable and conventional long-term
agriculture? ecological balance, using methods like
crop
rotation, organic fertilizers, and reduced
chemical
use. Conventional agriculture emphasizes
high
yields through monoculture, synthetic
fertilizers,
and pesticides.
, What effect does conventional Conventional agriculture can lead to soil
agriculture have on the soil? degradation, reduced fertility, erosion, and
loss of
biodiversity due to heavy reliance on
chemicals
and monoculture practices.
What are the primary goals of The primary goals of sustainable
sustainable agriculture? agriculture
include preserving environmental quality,
enhancing soil health, promoting
biodiversity, and
ensuring economic viability for farmers.
What are different types/sources Sources of water pollution include
of agricultural
water pollution? runoff (pesticides, fertilizers), industrial
discharges
(heavy metals, chemicals), sewage and
wastewater,
and oil spills.
What are the different Types of air pollution include particulate
types/sources matter,
of air pollution? nitrogen oxides, sulfur dioxide, carbon
monoxide,
and volatile organic compounds, sourced
from
vehicles, industrial emissions, and burning
fossil
fuels.
