Chapter 1-Resources- Class 8-NCERT- Geography
Resources,class 8
The document defines and classifies resources according to their origin, renewability, distribution, development potential, and how they are obtained and used by humans. Resources are things that fulfill human needs and have utility or value. They include natural resources drawn directly from nature as well as human-made resources created through human ideas, knowledge, and technology. Resources can be biotic or abiotic, renewable or non-renewable, ubiquitous or localized, actual or potential. People are an important resource, and sustainable development aims to ensure responsible use of resources for current and future generations.
Resources class 8
The document discusses different types of resources. It defines resources as objects or substances that have utility or usability. Resources can have economic value, like metals, or no economic value, like landscapes. Some resources gain economic value over time with inventions or technology. There are three main types of resources: natural resources found in nature like water and soil; human-made resources that are modified versions of natural substances like buildings and machinery; and human resources which are people whose skills and knowledge allow for better resource use and development. The distribution of natural resources depends on physical factors like climate and terrain, so their availability varies in different regions. Conservation of resources involves sustainable use to allow for renewal without compromising future needs.

Class 8 chapter 1 geography 1.pptx
Anything that satisfies a need is considered a resource. Resources have utility or usefulness, economic value, and are derived from natural or human-made sources. The distribution of resources is unequal globally depending on factors like climate and geography. People are the most important resource as their ideas, knowledge, and inventions can transform natural materials into new resources through technology over time. Conservation of resources through sustainable use and development is important to preserve the planet's life support systems for future generations.
RESOURCES & TYPES
Resources are materials that have value and are used to satisfy human needs. They can be biotic or abiotic, renewable or non-renewable. Natural resources come directly from nature without modification, examples include water, air and solar energy. Human-made resources are created from natural resources through human modification, such as buildings, books and vehicles. Human resources refer to people who can utilize other resources efficiently through skills and expertise, like doctors, teachers and politicians.
Sustainable development & The use of Resources
This document discusses sustainable development and the use of resources. It focuses on land as a key resource for Caribbean countries. Land can be misused through poor planning, mining, deforestation, and unsustainable farming techniques like shifting cultivation and overgrazing. This damages soils and increases erosion. Conservation efforts are needed like replanting vegetation after mining, controlled logging, using fertilizers, and contour ploughing to retain soils. Sustainable development requires balancing the economy, environment and social needs of people.
Resources
This document discusses different types of resources. It defines a resource as something that can be used to produce wealth or benefit. Resources are categorized as economic, biological, land or natural, and human. Economic resources include goods and services used to produce products. Biological resources are substances required by living organisms. Land resources include materials found in the environment like water, air, and minerals. Human resources refer to the workforce. The document provides examples of each type and notes that resources of Bangladesh include natural gas, minerals, fertile soil, water, and its population.
Bio-resources & Natural resources
Resources are anything that has utility and adds value to your life. Air, water, food, plants, animals, minerals, metals, and everything else that exists in nature and has utility to mankind is a ‘Resource’. The value of each such resource depends on its utility and other factors, e.g. metals are gold, silver, copper or bronze have economic value; i.e. they can be exchanged for money. Mountains, rivers, sea or forests are also resources but they do not have economic value. The given presentation briefly explants about the classification and availability of bio-resources and natural resources( mainly emphasizing on Indian natural and bio-resources) and also describes about bioproducts or green products.
Resource, Geography
The document discusses different types of resources including renewable and nonrenewable resources. Renewable resources like solar, wind, and water can be replenished within a short period of time, while nonrenewable resources like coal, oil, and gas cannot be replenished on a human timescale. Resources can also be classified based on their origin as biotic (living) or abiotic (non-living), as well as their potential, actual, or reserve levels. Unequal distribution of resources between countries can lead to interdependence, uneven development, and conflicts over control of resources. Conservation aims to use both renewable and nonrenewable resources efficiently and extend their availability for future generations.

Resources
This document defines and describes different types of resources. It discusses resources as anything that satisfies human needs and wants, including materials, energy, services, staff, knowledge, and assets. Resources have the key characteristics of utility, limited availability, and potential for depletion or consumption. The document then defines and provides examples of different specific types of resources, including natural resources, biological resources, economic resources, human resources, land resources, soil resources, and discusses sustainable development and resource planning.
Resource Classification
This document discusses different ways of classifying resources. It can classify resources based on their origin (biotic vs abiotic), exhaustibility (renewable vs non-renewable), ownership (individual, community, national), and development status (potential vs developed). Renewable resources like forests can replenish, while non-renewable resources like fossils fuels are limited. Resources can be owned privately, accessed by a community, or belong to a entire nation. Potential resources have not been utilized yet, while developed resources have been surveyed. Ecological resources include flora, fauna, natural and managed ecosystems, and provide direct benefits as well as maintaining ecological balance.
Natural resources and types of natural resources
Natural resources can be classified in several ways based on their origin, abundance, renewability, and development stage. Biotic resources like wildlife originate from living organisms, while abiotic resources like metals are non-living. Resources are also exhaustible if they can be depleted, like fossil fuels, or inexhaustible if replenished like solar energy. Renewable resources regenerate naturally, unlike non-renewable resources. Potential resources have yet to be developed, whereas actual resources are currently being used. Conservation of natural resources is important as most are finite or non-renewable.

Resources - Geography - Chapter 1
A resource is a physical material that humans need and value such as land, air, and water. Resources are characterized as renewable or nonrenewable; a renewable resource can replenish itself at the rate it is used, while a nonrenewable resource has a limited supply.A resource has some value. The value can be associated with money (i.e. you have to pay money to get it), or just mental satisfaction (e.g. when you look at a beautiful painting or scenery, it feels pleasant, so the painting or scenery has utility).
Examples of resources include books, stationery material, clothes, utensils, furniture, your teacher, school, rivers, water, electricity, and so on. A substance may or may not be a resource depending on our knowledge. If we do not know how to write with a pen, then certainly the pen has no utility for us. So, in this case, the pen is not a resource. However, for those who know how to use a pen, it is a resource. So technology, ideas, knowledge, inventions, discoveries, etc. make a substance a resource.
Time may also be a factor involved in making a substance a resource. Water has always been there, but its utility to manufacture electricity was not always known.
When people realized that water can be used to produce electricity, water became a resource in a new way.
Resources may be natural, human, or human-made.
Natural resources are those that are taken from nature. They are used without modifying them, i.e. in the same form as they exist in. Rivers, lakes, air, soils, minerals, trees, mountains, etc. are natural resources.
On the basis of level of development of resource, a natural resource can be actual or potential. An actual resource is one which is used currently. We know their quantity. Examples are: coal deposits. A potential resource is one whose utility is not known at present or is not used despite having utility; instead it may be useful at some time in future. It means that it has the potential to have utility, although it does not have any today. Examples include uranium deposits in Ladakh.
On the basis of origin, a resource can be abiotic or biotic. A biotic resource is one that has life. Examples: plants and animals. An abiotic resource is non-living. Examples: soils, rocks, furniture, books.
Natural resources may also be classified as renewable and non-renewable. A renewable resource can be used without any risk of its ending up. They exist in unlimited quantity, for example solar energy, and wind energy. On the other hand, use of non-renewable resources need to be controlled since once they end up, they cannot be renewed. Examples: coal, petroleum.
On the basis of distribution, a resource can be ubiquitous or localised. A ubiquitous resource is found everywhere, like air. A localised resource is, however, found in certain parts of the world only, like we cannot find coal everywhere.

Primary economic-activity classroomcobalt
Primary economic activity involves extracting natural resources from the land and sea, such as through farming, fishing, forestry, mining, and quarrying. Natural resources are things provided by nature that are useful to people, and can be renewable like water, fish, plants and crops; or non-renewable like coal, oil and gas. Most people in developing countries work in primary economic activities compared to developed countries due to the types of resources available.

In this lesson you will comprehend how the consumption of everyday p.docx
In this lesson you will comprehend how the consumption of everyday products affects the availability of renewable and nonrenewable natural resources for future generations and learn about environmental threats to our home.
Read the following information to help you define three different types of resources—renewable, nonrenewable, perpetual.
1. On earth, there are only limited amounts of fossil fuels, such as coal, oil and natural gas. There are also only limited amounts of minerals, such as iron, copper and bauxite. These resources either cannot be replaced by natural processes or require millions of years to replenish.
2. Some renewable and nonrenewable resources can be recycled or reused. This process decreases the rate at which the supplies of these resources are depleted. For example, aluminum cans can be recycled and turned into “new” cans or other aluminum products many times over. Recycling reduces the need to mine bauxite, the mineral used to manufacture aluminum.
3. Renewable natural resources include plants, animals and water when they are properly cared for. Minerals and fossil fuels such as coal and oil are examples of nonrenewable natural resources.
4. Trees, wildlife, water and many other natural resources are replaced by natural processes. Plants and animals can also be replenished by human activities. Water is continuously cycled and reused. Sunlight, wind, geothermal heat, tides and flowing water are perpetual resources.
Water is a resource that is typically considered renewable. However, over usage of water can cause us to use it faster than it is replenished.
The chart below approximates daily water consumption in the United States:
1. Thermoelectric Utilities 187 billion gallons/day
2. Irrigation 137 billion gallons/day
3. Public Water Supply 36 billion gallons/day
4. Industry 26 billion gallons/day
5. Rural and Livestock 8 billion gallons/day
Total 394 billion gallons/day
What are the threats to our environment?
Biodiversity
Biodiversity is all of the Earth's plants, animals, ecosystems and genes. It includes the tallest tree, the smallest insect, and the most delicate coral reef ecosystem. Biodiversity is what allows the Earth and all of its creatures to adapt and survive.
As humans, we are completely dependent on biodiversity for survival. Yet we are destroying large parts of our natural world. In places far and wide, humans are squeezing out other forms of life, sometimes causing the extinction of entire species.
We have the power to change our course. Each of us can act to protect our biodiversity and help create a sustainable future for life on Earth. Learn more about biodiversity and how

water.pptx
Water is essential for life but is a limited resource. It exists in liquid, solid and gas forms on Earth. Most water is salty ocean water, while only 3% is freshwater, and less than 1% is accessible for human use. Water is needed for biological processes like nutrient transport and thermoregulation, as well as for industrial, agricultural and other uses. Water shortages can occur when demand exceeds supply and may exacerbate global conflicts. Educating others about water conservation is important through activities like art, stories, investigations and understanding our local water systems.

It also provides sample exam questions from previous years on these topics, such as questions about population growth and control, overpopulation, resource exploitation and conservation, and various energy sources and sustainability issues. The syllabus aims to equip students with an understanding of these important environmental subjects.
Management of natural resources
Natural resources provided by nature such as soil, air, water, forests, wildlife, coal and petroleum are essential for human survival but are present in limited quantities and require careful management. Resources can be classified as either exhaustible like coal and petroleum or inexhaustible like air and water. Conservation efforts aim to protect these natural resources for future generations through laws and initiatives like the Ganga Action Plan while reducing pollution and contamination. The three R's of reduce, reuse and recycle can help minimize environmental impact and make resources last longer.
Eco chapter 2 n
The document describes how the environment sustains life through providing basic needs like food, water, air, shelter and space. It defines key terms like ecosystem, habitat, food chain and explains the roles of humans as resource users and decision makers who can prevent waste. Living things obtain nutrients from food sources in their habitat and energy is transferred between organisms through food chains within ecosystems.
