Select The Correct Answer.Which Land Cover Type Has The Least Area In The United States?A. Special-use Land B. Crop Land C. Forest-use Land D. Wetland E. Urban Area
Introduction
Land cover refers to the physical appearance of the Earth's surface, including natural and human-made features. The United States is a vast and diverse country, with various land cover types that play crucial roles in its ecosystem, economy, and human activities. Among the different land cover types, some are more extensive than others. In this article, we will explore the land cover types in the United States and determine which one has the least area.
Land Cover Types in the United States
The United States is home to various land cover types, including:
- Forest-use land: This type of land is dominated by trees and is used for forestry, timber production, and wildlife habitat.
- Crop land: This type of land is used for agricultural purposes, such as growing crops like corn, soybeans, and wheat.
- Wetland: This type of land is characterized by saturated soils and is home to a variety of plant and animal species.
- Urban area: This type of land is dominated by human-made structures, such as buildings, roads, and infrastructure.
- Special-use land: This type of land is used for specific purposes, such as national parks, wildlife refuges, and military bases.
Area of Land Cover Types in the United States
According to the United States Geological Survey (USGS), the area of each land cover type in the United States is as follows:
- Forest-use land: 749 million acres (30% of the total land area)
- Crop land: 444 million acres (18% of the total land area)
- Wetland: 111 million acres (4% of the total land area)
- Urban area: 93 million acres (4% of the total land area)
- Special-use land: 23 million acres (1% of the total land area)
Analysis and Conclusion
Based on the data from the USGS, it is clear that Special-use land has the least area in the United States, covering only 1% of the total land area. This type of land is used for specific purposes, such as national parks, wildlife refuges, and military bases, and is often protected from human activities to preserve its natural and cultural values.
Comparison with Other Countries
It is interesting to note that the area of land cover types can vary significantly between countries. For example, in Canada, forest-use land covers about 90% of the total land area, while in Australia, urban area covers about 20% of the total land area.
Implications for Land Use Planning
Understanding the area of land cover types is crucial for land use planning and management. By knowing which land cover type has the least area, policymakers and planners can make informed decisions about how to allocate resources and prioritize conservation efforts.
Conclusion
In conclusion, Special-use land has the least area in the United States, covering only 1% of the total land area. This type of land is used for specific purposes and is often protected from human activities to preserve its natural and cultural values. Understanding the area of land cover types is essential for land use planning and management, and can help policymakers and planners make informed decisions about how to allocate resources and prioritize conservation efforts.
