JSS 1: Renewable and non-renewable energy

-
                       Resources
Resources refer to all the materials present in our environment which are used by living things.

 Natural Resources: 

Natural resources are resources that occur on Earth and are formed through natural processes without human intervention. Humans require many useful things available in nature to live on this planet. Examples of natural resources are air, water, wood, animals, and minerals. When humans use natural things to make a new thing that increases its value, it is known as a man-made resource.

Types of Natural Resources

There are two types of energy resources:

1. Renewable energy resource  

2. Non-renewable energy resources


Types of natural resources

             Renewable resources

Renewable resources are those that cannot be depleted. They are always available and can be reused. Examples of renewable energy resources: Sun, Wind, Water, Soil and Biogas

                Non-renewable Resource

They are natural resources that are limited in quantity. These resources cannot be supplied or regenerated in a short duration of time. These resources cannot be reused.

Examples of non-renewable resources are: fossil fuel, coal, natural gas, petroleum, nuclear energy

Differences between the renewable and non-renewable resources

Renewable Resources

Non-renewable Resources

1. Can be replaced by natural processes in a short duration of time or can be recycled.


1. These are natural resources that either can not be replaced or may take millions of years to be replaced by natural processes like coal and oil.

2. It can be reused or recycled and used multiple times.

2. It cannot be reused or recycled.

3. Some examples are wind energy, solar power, hydroelectricity, and geothermal.

3.  Some of the examples are petrol, coal, Natural gas, nuclear energy, and fossil fuels.

4. There is no harm to the environment by using renewable resources.

4. Huge harm done to the environment because of the harmful emissions.

                               Shadow  A shadow is an area in which light rays from a source cannot reach                           Types of shadow  There are two types of shadow: 1. Umbra: A region of complete darkness 2. Penumbra: A region of partial darkness                                   Eclipse  An eclipse is a result of a shadow cast by one heavenly body on another                           Types of eclipse  There are two types of eclipse, namely: 1. Eclipse of the sun (Solar eclipse) 2. Eclipse of the moon (Lunar eclipse)                         Solar eclipse  Solar eclipse occurs when the moon comes between the sun and the earth                           Lunar eclipse  A lunar eclipse occurs when the earth comes between the sun and the moon                            Image  An image is a visual representation of an object.                    Types of image  The two types of images are: 1. Real image:  A real image is an image that can be f

JSS 1: Gravitation and weightlessness

                     Gravitation  Gravitation  is defined as a natural phenomenon by which all physical bodies attract one another. Gravity: This is   the force that attracts a body towards the centre of the earth.                  Gravitational pull  Gravitational pull is the force of attraction to the earth. The gravitational pull on the moon is about one-sixth of that of the Earth and that is why astronauts seem lighter and need special boots and clothes to walk on the moon                Effects of gravitational pull 1. Gravitational pull affects the weight of an object  2. It helps human beings to stand well on the earth  3. It keeps the planets of the solar system in their positions  4. It helps the moon to keep revolving around the earth  5. It helps in the formation of tides                    Centre of gravity (C.G.) The Centre of gravity is the average point on an object where the total weight is located.

Light is a form of energy called luminous energy which can enable us to see.                       Sources of light  There are various sources of light, namely: 1. Natural sources e.g.  sun, stars, fire-flies, etc  2. Artificial sources e.g.  candles, electric torches, electric lamps, fluorescent lights, etc                   Transmission of light  Light travels at a speed of 3.0 x 10⁸m/s in a vacuum or space and through a material medium  Transparent objects: They are objects that allow light to pass through them and objects can be easily seen through them. Examples: glass, water, air, lenses, etc  Translucent objects: They are objects that allow light to pass through them but objects cannot be seen through them  Examples: frosted glass, tissue paper, tinted car windows, etc  Opaque objects: They are objects that do not allow light to pass through them and objects can not be seen through them. Examples: wood, leather, metal sheets, walls, etc              Rays and beams
