How does soil formation contribute to sustainable development?
-
By providing a foundation for agriculture
-
By regulating water flow and preventing erosion
-
By supporting biodiversity and ecosystem functioning
-
All of the above
D
Correct answer
Explanation
Soil formation is essential for sustainable development as it provides the basis for agriculture, regulates water flow and prevents erosion, and supports biodiversity and ecosystem functioning. Healthy soils are crucial for food security, water management, and the overall resilience of ecosystems.
The ancient Maya civilization, known for its advanced agricultural practices, developed a unique system of raised fields, called "chinampas," to increase crop yields. What was the primary purpose of chinampas?
-
To improve soil fertility
-
To control flooding and waterlogging
-
To create additional agricultural land
-
All of the above
D
Correct answer
Explanation
The Maya developed chinampas, raised fields, to improve soil fertility, control flooding and waterlogging, and create additional agricultural land. These raised fields allowed the Maya to cultivate crops year-round and increase their agricultural productivity.
The ancient Inca Empire implemented a sophisticated system of agricultural terraces, known as "andenes," to optimize crop production in mountainous regions. What was the primary benefit of using andenes?
-
Preventing soil erosion
-
Conserving water
-
Increasing the amount of arable land
-
All of the above
D
Correct answer
Explanation
The Inca andenes served multiple purposes: they prevented soil erosion, conserved water, and increased the amount of arable land available for cultivation. These terraces allowed the Inca to grow a variety of crops, even in challenging mountainous terrain.

C
Correct answer
Explanation
Agriculture is the largest land use in the world, occupying approximately 33% of the world's land surface.
What is the term used to describe the practice of using the same land for both agriculture and livestock grazing?
-
Agroforestry
-
Silvopasture
-
Permaculture
-
Polyculture
B
Correct answer
Explanation
Silvopasture is the practice of using the same land for both agriculture and livestock grazing, often by planting trees or shrubs among the pasture grasses.
Which of the following is NOT a type of sustainable agriculture?
-
Organic farming
-
Permaculture
-
Conventional agriculture
-
Agroforestry
C
Correct answer
Explanation
Conventional agriculture, which relies on synthetic fertilizers and pesticides, is not considered to be a type of sustainable agriculture, as it can lead to environmental problems such as water pollution and soil erosion.

-
Monoculture
-
Polyculture
-
Intercropping
-
Crop rotation
D
Correct answer
Explanation
Crop rotation is the practice of rotating crops in a field to improve soil fertility and reduce the risk of pests and diseases.

-
Sustainable agriculture
-
Organic farming
-
Permaculture
A
Correct answer
Explanation
Conservation agriculture is the practice of managing agricultural land to protect and enhance natural ecosystems.
Which of the following is NOT a principle of conservation agriculture?
-
Minimizing soil disturbance
-
Maintaining soil cover
-
Using crop rotations
-
Using synthetic fertilizers
D
Correct answer
Explanation
