1. The scale of analysis on the Map is at highest to show the globe. 2.The Southeast Asia is shaded in a single color in the world map because its produces 0.5 tons - 1.0 tons per acre of rice. 3. The rice production data for Southeast Asia and West Africa differs because the first produces 0.5 tons - 1.0 tons per acre of rice while the later produces 0.56 per acre of rice. 4. The Green Revolution was birthed after technological advancements in the agricultural field. One example of this is the introduction of pesticides and GMO crops. With genetically modified crops and special seeds constructed to prevent insects, crops were able to produce more abundantly hence the Green Revolution. 5. The green revolution lead to improvized rice seed for efficiency. 6. Mechanization changed rice production in less developed countries because its led to abundancy and efficiency or a higher yield of rice production 7. Agricultural chemicals contributed to the change in rice production. With advancements in agricultural technology, thanks to the Green Revolution, the farming world has seen improvements in cultivation. This holds true with rice. More rice is being producted more effectively and at a faster rate.

Which of the following best explains the economic advantage of the type of farm-produced goods shown in the images?

Compared to plain milk or fresh fruit, these value-added agricultural goods significantly increase the price of the farm products sold and increase earnings for farmers.

Which of the following spatial patterns is best explained by bid-rent theory?

Concentric rings of different agricultural activities surrounding a city in the midwestern United States

Which of the following explains why multiple early hearths of domestication and diffusion of plants and animals arose across the world in Central America, the Fertile Crescent, the Indus River valley, and Southeast Asia?

Domestication of plants and animals evolved in each hearth independently of one another as societies in each area learned and applied the process to local plants and animals.

Which of the following explains an impact of globalized agricultural commodity chains on consumers as compared to producers?

Drought and depletion of groundwater sources in developing countries cause a rise in global grain prices and associated higher costs for food.

The two images represent two different methods of raising livestock in the United States. Which of the following statements most accurately compares these two agricultural practices?

Feedlots can minimize costs associated with livestock production because feedlots do not use as much space as cattle ranching.

Based on the diagram of von Thünen's model of agricultural land use, which statement best explains the connection between land value and agricultural production regions?

Grain crops require extensive acreage and are grown on land that is less costly and farther away from the market than other agricultural land uses.

In less developed countries, pesticides are typically applied by hand, whereas pesticides are typically applied by tractors or aircraft in more developed countries. Which of the following best explains the risks associated with pesticide applications?

In a country with a lower level of economic development pesticides would be applied by human labor putting the farmer and farm workers at risk. In countries with higher levels of economic development, pesticides are applied mechanically, or through crop dusting, which spreads the pesticides over a greater area and has a negative impact on the environment.

Based on the different types of land use shown in the image, which of the following best explains why soil salinization is a concern in the arid landscape shown?

Irrigation increases the salt content of the soil, which disrupts the growth of crops and degrades soil fertility.

Which of the following best explains why farmers would plant both strawberries and watermelons in the same field?

Limited farmland encourages intensive farming with intercropping to produce high yields.

Which of the following best explains the importance of climate to agricultural practices?

Midlatitude climates tend to support similar agricultural crops and practices, such as wheat farming in the United States and China.

Palm oil, an edible vegetable oil used in processing packaged food products, is obtained from the fruit of the oil palm tree, grown only in the tropics. Which of the following explains how global demand for palm oil has proved beneficial and detrimental for countries such as Indonesia and Malaysia?

Palm oil exports provided substantial corporate profits, but the growth in the industry resulted in heavy deforestation in both countries.

Which of the following best explains why the New England region, located in the northeastern United States, would specialize in market gardening agriculture rather than other types of agriculture, such as grain farming?

Several large cities on the East Coast provide a growing market and shorter distances for transporting market gardening products.

Sheep production in New Zealand and poultry production in Arkansas produce food animals for human consumption. Which of the following best describes the differences in the agricultural practices and land use for these products?

Sheep production is an example of extensive agriculture requiring large pastures, whereas poultry production is an example of intensive agriculture often practiced indoors.

During the Green Revolution, agricultural practices from more developed countries diffused to less developed countries in Asia and Africa. Which of the following best explains the Green Revolution's highly variable level of success in increasing agricultural yields?

Small-scale farmers in Asia often lacked the resources necessary to acquire the hybrid seeds and the chemical inputs to grow them, leaving large gaps in the success of the Green Revolution outside of urban cores.

In the South Asian country of Sri Lanka, tea is farmed as a monoculture. Which of the following best explains why tea plantations are common in Sri Lanka and tea exports are important to the country's economy?

Sri Lanka's unique climate and terrain make it one of the only countries where tea plants thrive.
