Which of the following soil zones is found in the southeast part of Alberta?

The correct answer is Brown, as this soil zone is characteristic of the southeast region of Alberta. Brown soil zones typically feature a rich topsoil layer that is high in organic matter, making it fertile and suitable for agricultural activities. This type of soil is commonly found in areas with a moderately dry climate, which aligns with the environmental conditions in the southeastern part of Alberta.

In contrast, the other soil zones, such as Dark Gray, Black, and Gray, are associated with different regions and climatic conditions. Dark Gray soils are usually found in regions with more moisture, often in the central areas of Alberta, while Black soils, known for their high organic content, are predominant in the grassland regions of Alberta's northwestern areas. Gray soils generally occur in cooler, wetter climates, which does not apply to the southeast portion of Alberta. Understanding these distinctions is crucial for recognizing the diverse agricultural zones within the province and how they relate to soil types.
