Explanation:
Natural resources are classified based on various factors such as their abundance, distribution, durability, and origin. In this specific question, the classification is based on their distribution.

Distribution:
Distribution refers to the geographical spread or availability of natural resources. It determines whether a resource is found everywhere or is limited to specific regions.

Ubiquitous Resources:
Ubiquitous resources are those that are found almost everywhere on the Earth's surface. These resources have a widespread distribution and are not limited to specific regions. Examples of ubiquitous resources include air, water, and sunlight. These resources are available in abundance and can be found in almost every part of the world.

Localized Resources:
Localized resources, on the other hand, are limited to specific regions or areas. These resources are not evenly distributed and are found only in certain geographical locations. Examples of localized resources include minerals, fossil fuels, and certain types of vegetation. These resources are often concentrated in specific regions due to geological or environmental factors.

Importance of Classification:
The classification of natural resources based on their distribution is important for several reasons. It helps in understanding the availability and accessibility of resources in different regions. It also assists in planning and managing the sustainable use of resources. Additionally, it aids in identifying regions that are rich in specific resources, which can have implications for economic development and trade.

Conclusion:
In conclusion, natural resources can be classified based on their distribution as ubiquitous resources, which are found everywhere, and localized resources, which are limited to specific regions. This classification helps in understanding the availability and accessibility of resources and has implications for planning and management.
