The Simplified NOTEs (The Last Scientific Prayer)

Hello Young Scientists, Welcome to the PHOTO DAY.

Today we are going to look at how People Use Sustainable Energy and The Scientific Ideas behind those ways.

First and foremost, we may all have heard of the ability to harness energy from the sun (solar or radiant energy) into electrical energy, and the generated energy can then be channelled into various forms of energies like light energy, thermal or heat energy or even mechanical energy, at home or even at the industries.

NOTE: Trapping the radiant energy is made possible by the use of solar panels that comprises of solar cells.

As a result, the combustion of fossil fuels is reduced since no fossil will have to be burnt in thermal plants or generators in an attempt to generate electrical energy, thereby reducing the production of excessive green house gases that will also reducing the occurrence of global warming. Therefore using solar energy is a convenient way of reducing global warming and promoting ecological friendliness.

Second point to add, Hydroelectric energy, it can also be called Hydropower or Hydroelectric power. It is a form of sustainable energy that is generated from moving water. It is generated by converting the kinetic energy of the moving water into electrical energy using turbines that have been connected to dams.

The generated electrical energy is made available to various forms of energies such as light, mechanical, sound and heat.

In addition, Windmill energy is a renewable energy that is sustainable, and it is generated from harnessing the wind into electrical energy. The harnessing process is only possible when a windmill is mounted on a highland that will convert the moving air (wind) into electrical energy. Hence the electrical energy can then be channelled into various forms of energies such as light, mechanical sound and heat.

In addition, Ocean energy ( ocean & tidal energy) is a renewable and sustainable energy that is generated from the tides and wind on the ocean. The tides and wind is converted from mechanical energy to electrical energy.

Furthermore, Nuclear energy is a renewable energy that is also generated from the nucleus of atoms. Since atoms are always in existence nuclear energy may never get exhausted therefore nuclear energy is a renewable and sustainable energy. But it's emissions has negative impact on the environment as the gases are likely to contain greenhouse gases that may tend to cause global warming. 

Lastly, Geothermal energy is also a sustainable and renewable energy that's generated from from heath beneath the Earth's crust. The heat is mostly in the form steam from boiling waters.

LAST TOPICs FOR THE TERM : LANDFORMS

Landforms are features on the Earth's surface that is part of the terrain.

Types of Landforms

1. Mountains

2. Plateau

3. Plains

4. Hill

5. Valleys

Some terminologies associated with Landforms

-> Mutualism is the  interaction between two living things in which both organisms benefit from each other, i.e, both exchange of substances

-> Commensalism is a type of relationship between two living organisms in which one organism benefits from the other without harming it. A commensal species benefits from another species by obtaining locomotion, shelter, food, or support from the host species, which (for the most part) neither benefits nor is harmed. 

-> Parasitism is feeding relationship in which one organism, called Parasite, lives in/on another organism, called Host, for survival. 

CAREERS IN THE STUDY OF SCIENCE.

Careers in the study science is the job opportunities that are available for individuals who pursue the study of science to advance levels.
