Questions and Answers

1.

About 38% of Earth's land surface is used for ___________________
- A.
  
  Agriculture
- B.
  
  Architecture
- C.
  
  Conservation corridors
- D.
  
  National parks
Correct Answer
A. Agriculture

Explanation
The correct answer is agriculture because the question asks about the use of Earth's land surface, and agriculture is the practice of cultivating crops and raising livestock for food, fiber, and other products. Agriculture is a widespread activity that requires a significant amount of land for farming and grazing, making it the most likely option among the given choices.

Which of the following is soil not formed by?
- A.
  
  Weathering
- B.
  
  Decomposition
- C.
  
  Erosion
- D.
  
  Photosynthesis
Correct Answer
D. Photosynthesis

Explanation
Soil is formed through the process of weathering, which involves the breakdown of rocks and minerals. Decomposition also plays a role in soil formation as organic matter decomposes and contributes to the soil's nutrient content. Erosion, on the other hand, is the process of soil being moved or transported from one location to another. Photosynthesis, however, is the process by which plants convert sunlight into energy, and it does not directly contribute to soil formation.

True or false: Human activities cause more erosion than natural events
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Human activities such as deforestation, mining, construction, and agriculture often contribute significantly to erosion. These activities can remove vegetation cover, disturb soil structure, and increase the amount and speed of water flow, leading to increased erosion rates. Natural events like wind, water, and ice also cause erosion, but human activities can exacerbate and accelerate these processes, resulting in more erosion overall. Therefore, it can be concluded that human activities cause more erosion than natural events.

Fill in the blank: _____________ is the raising and grazing of livestock

Correct Answer
ranching

Explanation
Ranching refers to the practice of raising and grazing livestock. It involves managing large areas of land where animals such as cattle, sheep, or horses are bred, raised, and allowed to graze freely. Ranching typically involves activities such as providing food and water for the animals, maintaining their health, and managing the land to ensure sustainable grazing.

Fill in the blank: ___________________ was one of the most significant desertification events that took place in the 1930s.

Correct Answer
The Dust Bowl

Explanation
The Dust Bowl refers to a period of severe dust storms that occurred in the 1930s, primarily in the Great Plains region of the United States. It was a significant desertification event that resulted in the destruction of farmland, crop failures, and mass migration of people. The combination of drought, poor soil conservation practices, and strong winds led to the erosion of topsoil and the creation of massive dust storms that blanketed the region. This environmental disaster had a profound impact on agriculture, economy, and the lives of people in the affected areas.

What is the buildup of salts in the upper soil horizons?
- A.
  
  Fossil fuels
- B.
  
  Salinization
- C.
  
  Industrial Agriculture
Correct Answer
B. Salinization

Explanation
Salinization refers to the buildup of salts in the upper soil horizons. This occurs when there is excessive irrigation or poor drainage, causing water to evaporate and leave behind salt deposits. As these salts accumulate, they can negatively affect plant growth and soil fertility. Salinization is a common problem in arid and semi-arid regions where water resources are limited and irrigation is necessary for agriculture. It is important to manage irrigation practices and improve drainage systems to prevent or mitigate salinization and maintain healthy soil conditions for sustainable agriculture.

1. True or false: Traditional agriculture requires the use of fossil fuels.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Traditional agriculture refers to farming methods that rely on traditional techniques and tools, such as manual labor and animal power. These methods do not require the use of fossil fuels, as they do not involve the use of machinery or equipment powered by fossil fuels. Instead, traditional agriculture relies on human and animal power to perform tasks such as plowing, sowing, and harvesting. Therefore, the statement that traditional agriculture requires the use of fossil fuels is false.

8.

__________ are concentrated groups of livestock or poultry.

Correct Answer
feedlots

Explanation
Feedlots are concentrated groups of livestock or poultry. In feedlots, animals are confined to a specific area and provided with a controlled diet. This allows for efficient feeding and management of the animals. Feedlots are commonly used in the agricultural industry to raise livestock or poultry for meat production.

Which of the following is not a trait of Genetically Modified Organisms
- A.
  
  Rapid growth
- B.
  
  Frost tolerance
- C.
  
  Increased need for insecticides
- D.
  
  Pest resistance
Correct Answer
C. Increased need for insecticides

Explanation
Genetically Modified Organisms (GMOs) are organisms whose genetic material has been altered through genetic engineering techniques. They are typically designed to possess certain desirable traits. Rapid growth, frost tolerance, and pest resistance are all traits commonly associated with GMOs. However, increased need for insecticides is not a trait of GMOs. In fact, one of the main goals of genetic modification is to reduce the need for chemical insecticides by enhancing the plant's natural resistance to pests.

True or False: The Green Revolution was the introduction of new technology, crop varieties, and frost tolerance.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The Green Revolution was not the introduction of new technology, crop varieties, and frost tolerance. Instead, it was a period of significant agricultural advancements in the mid-20th century that focused on the development and adoption of high-yielding crop varieties, improved irrigation methods, and increased use of fertilizers and pesticides. The aim was to increase agricultural productivity and combat hunger and poverty. Frost tolerance was not a specific focus of the Green Revolution.
