APES Unit 5 Test Review (Land and Water Resources)

Front

What is drip irrigation?

Back

Drip irrigation is a method of watering plants that delivers water directly to the roots through a system of tubes, minimizing evaporation and preventing salinization of the land.

Front

What is contour plowing?

Back

Contour plowing is an agricultural practice where plowing is done along the contours of the land to reduce soil erosion and water runoff.

Front

What is soil erosion?

Back

Soil erosion is the process by which the top layer of soil is removed due to factors like water, wind, and human activity, leading to loss of fertile land.

Front

What are crop rotations?

Back

Crop rotations involve alternating the types of crops grown in a particular area across seasons to improve soil health and prevent soil erosion.

Front

What greenhouse gas is produced by cattle during digestion?

Back

Cattle produce methane, a potent greenhouse gas, as a byproduct of fermentation in their digestive systems.

Front

What is the main benefit of pesticide use?

Back

Pesticides are used primarily for disease control and crop protection, helping to increase agricultural productivity.

Front

What is eutrophication?

Back

Eutrophication is the process by which water bodies become overly enriched with nutrients, leading to excessive growth of algae and depletion of oxygen.

Front

What is the impact of over-grazing on soil?

Back

Over-grazing can lead to soil degradation, compaction, and increased erosion, as vegetation is removed and soil structure is compromised.

Front

What is the pesticide treadmill?

Back

The pesticide treadmill refers to the cycle where farmers must continuously increase pesticide use due to pests developing resistance, leading to higher costs and environmental impact.

Front

What is soil salinization?

Back

Soil salinization is the accumulation of soluble salts in soil, often due to improper irrigation practices, which can harm plant growth.
