Explain why areas on different continents such as western europe and coastal east asia have similar climates at different latitudes

Just because towns are on the same latitude doesn't mean they will have the same climates. Different air and ocean currents make all the difference.Sep 7, 2002

What are the components of soil and why does fertile soil need to be sustained as a resource?

The components of soil in mineral particles, water, air, and organic matter like decaying plant material. It needs to be sustained because it proved nutrient for plant/crops to grow healthy.

2 ways humans have adapted to topographical challenges

1. Terrace building for farming protects soil on steep sloped, while irrigation or drainage schemes influence water availability 2. Adding fertilizers enhances the soil fertility of cropland

Compare the advantages and disadvantages of clustered, dispersed, and linear settings.

Advantages of clustered- social unity, allows resident to share common resources, and expand their land outward. Disadvantage of clustered- social friction or to a family's fields extending too far away from the settlement. Advantage of dispersed- promote independence and self sufficiency Disadvantage of dispersed- difficult terrain, resources like water and fertile land are scarce, lack of social interaction;shared institutions, such as schools; and ability to easily defend their residents. Linear advantages- people settle along these features because they provide access to water or transportation. Linear disadvantages- fields stretch out from the line of settlement, making the far end of those fields distant from homes.

Describe how intensive and extensive farming practices are determined in part by the bid-rent theory.

Both subsistence and commercial agriculture are practices at different scales known as intensive and extensive scales. The bid rent theory explains how land value determines how a farmer will use the land either intensively or extensively. Where land value is high farmers will but less land and use it intensively to produce the most agricultural yield per unit of land. Where land has lower value or is farther from the market, farmers will but more land and use it less intensively or extensively.

4 factors required for agriculture and how they interact.

Climate(Temperature and precipitation), elevation, soil, and topography. It is the combination of these four factors that allow specific crops to be grown in certain areas.

how does elevation affect the possibility of agriculture?

Elevation affects the growing season and what plants can be grown. Every 1,000 ft above sea level means a decrease in 3.6 F to temperature. The higher the elevation the shorter the growing season.

Environmental impacts of slash-and-burn farming techniques

Its very unsustainable as more farmers do this practice this also led to land becoming greatly degraded and open to erosion. Increasing loss of habitats for species, increasing air pollution. NOt only this since there's much release of carbon it contributes to global climate change.

Why is nomadic heding the most extensive type of agriculture.

Nomads stay on the move to allow their herds to continuously graze. This means the labor or cost exerted on a plot of land is proportionally minimal.

advances and impacts of the Second Agricultural Revolution

One of the most important tech during this revolution horse-drawn seed drill. Other tools like the McCormick mechanical reaper in the 1830s that mechanized harvesting grain or John deere invented the steel plow that made it possible to farm new areas. After these changes there was a pop boom similar to the first agri revolution. People had more food, nutritious diets, and longer life expectancy.

How does temperature and precipitation play a role in affecting the possibility of agriculture in an area?

Precipitation and temperatures needed for seeds to germinate, plants to grow, or livestock to have food needed to survive. Precipitation provides the moisture plants and animals require. Temperature is the key factor in determining the growing season.

Explain how the changes that some call the fourth agricultural revolution use geographic principles, skills, and technologies and have geographic consequences.

Some scientist refer to the use of info tech and data analytics as 4th agri. Revolution. This revolution involves GPS tech, smart tech farm equipment with sensors and wireless(percision agriculture), computer databases, and info processing powers this period is characterized by efficiency driven by data.

Compare the similarities and differences between subsistence and commercial farming practices.

Subsistence farming is meant to support family and local community. Also this farming is mostly found in semi-peripheral countries or peripheral. They require heavy human labor. While on the other hand commercial agriculture involves heavy invesments in labor and capital resulting in high yields for profit. They rely more on machines and fertilizers than human labor. Similarities between both use new technology just in different amounts, also fertilizers just more in commercial, and both can produce the same crops just at different yields.

Describe how the 3 agricultural revolutions were similar and how they were different.

The First Agricultural Revolution: From Hunting & Gathering to Settlement. The Second Agricultural Revolution: Business, Not Just Subsistence. The Third Agricultural Revolution: The Rise of Bioengineering. They were all similar because they all impacted human life with new technologies or practices that caused an agricultural revolution.

Describe how the agricultural practices of certain regions are influenced by the mediterranean climate?

The hot, dry summers are ideal for cultivating certain vines and trees(olive, fruit, and nut trees), shrubs(grape vines), and raising sheep and goats.

Define the term on Growing Season

The part of the year where the rainfall and climate is right to grow crops successfully.

Explain how geographic features would effect the grid pattern of the township and range system.

These land divisions over geographic features are very visible when passing by them. This separates geographic features by making a mix a property types.

compare the advantages and disadvantages of the green revolution for the food supply and environment in the periphery.

This revolution benefited the peripheral and semi-peripheral areas by bringing the new advances of the 3rd revolution like developing new high-yield strains of grain crops like wheat and rice. The disadvantage where the need for more water so taking from places that shouldn't have been taken from. This also leads to polluting water due to pesticides.
