Question

write a letter to your class teacher and ask him/har to give a lecture on the bad effect of global warming​

Answer 1

Good morning to my respected teachers and dear friends. I would like to speech on the Global Warming at this occasion. Global warming is a

continuously increasing environmental issue all over the world. There is no any single country responsible for its causes, all the countries worldwide are responsible for its ever increasing. Actually global warming is a global increase in the temperature of the earth because of our some daily activities. Our various activities heats up the earth which ultimately rises its temperature. Rise in temperature takes place when greenhouse gases (such a carbon dioxide, water vapours, nitrous oxide, methane, etc) trap heat and light from our surroundings and sun. Ultimately, rise in temperature hurts the lives of human beings, animals, and plants. There are many reasons for the increasing global warming however some of the primary and main causes are considered because of the Green House Effect.

It is affecting almost all parts of the world and causing sea level to rise, glaciers to melt and many more which covers all the low land islands. It is destroying huge forests, killing algae, acid rain, etc. Acid rain is very dangerous which may destroy anything in touch. Global warming causes natural fires which may wipe out whole forests. Continuous rise in the earth temperature affects agricultural crops, forests, marine life and life growth on the earth. It cannot be solved by the effort of only one country, it needs global effort of all countries to reduces its effects and completely eliminate it. thank you

Answer:

Electrons fill orbitals in a way to minimize the energy of the atom. Therefore, the electrons in an atom fill the principal energy levels in order of increasing energy (the electrons are getting farther from the nucleus).
