Mountains do not have direct economic worth as they cannot be bought or sold in the traditional sense. However, they hold immense value in various other aspects:

• Environmental Value: Mountains are home to diverse ecosystems and provide habitat for numerous plant and animal species. They play a crucial role in maintaining biodiversity and preserving natural resources.



 
• Recreational Value: Mountains offer opportunities for outdoor activities like hiking, climbing, skiing, and camping. They attract tourists and adventure enthusiasts, contributing to the tourism industry and local economies.



 
• Cultural Value: Mountains often hold cultural and historical significance for indigenous communities and societies. They are associated with myths, legends, spiritual beliefs, and traditional practices.



 
• Water Resource Value: Mountains are a major source of freshwater, as they capture and store snow and rain. They serve as watersheds, feeding rivers and supplying water for agriculture, drinking, and industrial purposes downstream.



 
• Aesthetic Value: Mountains are often considered breathtakingly beautiful and awe-inspiring. Their majestic landscapes, scenic views, and natural beauty have inspired artists, writers, and photographers throughout history.


 

While mountains might not have a direct economic worth, their value extends beyond monetary measures, making them highly valuable in various ways.

The type of resources on the basis of stock are:

• Renewable resources.
• Non renewable resources.

Most fossil fuels, such as natural gas, coal etc. are considered nonrenewable resources in that their use is not sustainable because their formation takes billions of years. Natural gas is a fossil fuel, like petroleum and coal, and is non-renewable.

The example of sustainable development among the given options is:

• Option B: Not wasting paper

Sustainable development refers to the practice of using resources in a way that meets the needs of the present without compromising the ability of future generations to meet their own needs. It involves considering the economic, social, and environmental impacts of our actions.

In the given options:

• Option A: Ignoring the lights when they are switched on but not required - This does not contribute to sustainable development as it involves wasteful energy consumption.


• Option B: Not wasting paper - This is an example of sustainable development as it promotes resource conservation and reduces the negative environmental impact of paper production.


• Option C: Using coal and petroleum deposits at a fast pace - This is not an example of sustainable development as it involves the rapid depletion of non-renewable resources.


• Option D: None of these - This option indicates that none of the given options are examples of sustainable development.

Therefore, option B (not wasting paper) is the correct example of sustainable development.

It is a renewable resource but though renewable resources also require a long period of time to get recharged. If once water is wasted it would a long span of time to be regenerated on the surface of the earth.

Yes, resources don't have same economic value.
•Although those resources satisfy the needs and have some use or utility, it depends on time and the change brought in them to make them economically valuable.
For example - Metals have an economic value while landscapes do not, but both have their use. If the same landscape is made into a tourist place where you've to buy tickets for viewing, it's economic value increases.

Yes with respect to Electricity water was a potential resource because few years ago there was not too develop technology to use the water to produce electricity by the process of hydroelectricity but now now we can generate electricity by using water.

Natural resources like rain, tides, waves are renewable but resources like natural gas, petroleum, coal are non- renewable resources.So this statement is false.

This world that has a value is a resource. A farmer who is valuable for our food who is a living being is a human resource. 

A farmer is a human resource . This is because all the humans are human resources. What makes them a resource is their

brain or wisdom which makes them know how to utilise other resources and modify them into useful things. Therefore, A farmer is a human resource and the statement is true

Yes we have to conserve resources bcoz as due to the increasing population it is decreasing day by day.
