Write an essay about environmental pollution

Answers

Answer:

In the modern world Environmental pollution has become a global threat. On the other hand, an essay on pollution or essay on Environmental pollution is now a common topic in each and every board exams. Students are very frequently asked to write an essay on pollution not only in school or college levels but also pollution essay has become a common essay in different competitive examinations. Thus, GuideToExam brings to you a different essay on pollution. You can pick up an essay on pollution as per your need.

We can classify pollution in many categories such as soil pollution, air pollution, water pollution, and noise pollution etc. Though pollution has become a threat to our environment, people are still not trying to control it. In the 21st century technological development in every field is given priority, but on the other hand, people are ruining the environment at the same time to fulfill their personal needs. Deforestation, urbanization and blind race in industrial development are some major causes of environmental pollution. People need to be conscious to save or protect our environment for future generation.The change in nature of the environment that gets harmful to living organisms is known as environmental pollution. On the basis of their nature pollution can be classified in different forms. They are soil pollution, water pollution, noise pollution, thermal pollution, visual pollution etc.

On the other hand, many of us don’t know that there are three types of pollution that occur by industries. Now a day’s industries are adding more pollution to our environment. Industries are also responsible for soil, water, and air pollution. Wastes from the industries are generally thrown in soil or water bodies and that cause soil and water pollution. Industries also emit dangerous chemicals in the form of gas. Our ecosystem is in real trouble due to this environmental pollution. We should consider it as an important task to stop environmental pollution to leave the globe safe for our successors.

On the other hand water pollution is another type of environmental pollution. In our country in most of the areas river water is the only source of drinking water. But almost every river in India is in the grip of pollution due to the negligence of people. Poisonous waste materials from industries are thrown in the rivers and as a result of that, the river water gets polluted. People also pollute river water in the name of traditional beliefs. For example, people still believe that the ashes (Asthi) after burial ceremonies should be thrown in the river, the hair needs to be thrown in the river after Mundan, etc. Water pollution gives birth to different water-borne diseases.

Environmental pollution needs to be stopped to secure the earth for our successors. We should keep our planet healthy to keep ourselves fit and healthy.

Answers

Mark Brainliest please

When condensation occurs closer to the
Earth's surface we can see fog, dew or Frost.

1. Fog:- As the temperature of the layers off the air the surface of the earth reduces water vapour condenses it turns into very small water particles and float in the air when the density of the droplets in the air increases fog occurs

2. Dew:- When moisture Laden air near the earth surface comes in contact with very cold objects condensation of vapour takes place and it turns into very small water droplets these water droplets. These water droplets stick to the surface of the cold objects and form dew.

3. Frost:- If the temperature of the air riches below 0 degree Celsius the Dew freezes. this frozen water droplet is called Frost

a. Mt. Fuji is too far away from Tokyo to pose a sig- nificant hazard.

who would use GIS to help plan activities?​

Answers

Answer:

A geographic information system (GIS) is a computer system that records, stores, checks, and displays data about locations on the Earth's surface.

Explanation:

Any information that involves a location can be used by GIS. The location can be specified in a variety of ways, including latitude and longitude, address, and ZIP code.

Data on people, such as population, income, and education level, can be included in the system. It may contain information on the landscape, such as the location of streams, various types of vegetation, and various types of soil. It could include information regarding factory, agricultural, and school locations, as well as storm drains, highways, and electric power lines.

A single map might incorporate pollution-producing areas, such as industries, as well as pollution-sensitive sites, such as wetlands and rivers, utilizing GIS. A map like this would aid in determining where water resources are most vulnerable.

2. EXPLIQUE o que foi o tratado de Tordesilhas

Answers

Answer:

El Tratado de Tordesillas dispuso la división del mundo no europeo entre Castilla y el Reino de Portugal, que organizó los primeros viajes de descubrimiento. El tratado fue ratificado por Castilla el 2 de julio de 1494 y por Portugal el 5 de septiembre de 1494.

Tras el descubrimiento de América, el Papa Alejandro VI determinó que todo al oeste de una determinada línea (480 km del archipiélago de Cabo Verde) pertenecía a Castilla y todo al este pertenecía a Portugal. Debido al cambio de la línea de demarcación en el tratado de Tordesillas, una gran parte del Brasil descubierto más tarde pasó a ser posesión portuguesa. Sin embargo, algunos historiadores sostienen que existe la posibilidad de que expediciones anteriores ya hubieran pisado Brasil, lo que implica que entraron en el Tratado de Tordesillas de forma premeditada.

(The word consumptionrefers to tuberculosis.) A.) Read the beginning of Jason's argumentative speech on the use of Internet slang and answer the question.The use of acronyms, or abbreviations, is not new. In fact, there are examples of the use of acronyms that date back to antiquity. Ancient scribes had a daunting enough task without having to write out every word. The Christian Church has inscribed the acronym INRI, which stands for the Latin Iesus Nazarenus Rex Iudaeorum ("Jesus the Nazarene, King of the Jews") over the crucifix for centuries. American and European corporations discovered long ago that it is easier to remember three letters than it is to remember three names. During the twentieth century, there was an upsurge in the use of acronyms that corresponded with the introduction of highly technical vocabulary. The tendency to shorten has an established history and many of these abbreviations have even found their way into the dictionary. Today, the use of time-saving abbreviations provides the language of internet and other wireless communication. But should it? Unlike in the past, this shortening does not represent a natural and necessary progression of language change. Internet slang is a manifestation of two much more serious problems with modern society intellectual laziness and too little time.Which sentence would provide the best transition into the counterargument paragraph of this essay?1- OMG! don't we have bigger problems as a society than taking a few short-cuts when it comes to communication?2- Until recently, the use of acronyms could be justified in most contexts.3- Many would argue that there is no harm in populating our communication with OMGs and LOLs given their widespread use.4- Intellectual laziness is a treatable disease, while finding more time is much more challenging.__________________________________________________________________B.) Read this excerpt from Jason's persuasive speech and answer the question.The main reason for using a slang unique to the Internet is to make communication easier.Which revision would add supporting evidence to best strengthen Jason's claim?1.) Add this sentence to the above excerpt: However, there is some debate about how internet slang influences everyday language.2.) Add this sentnece to the above excerpt: Studies suggest that saving a few keystrokes can both reduce stress and lead to more productivity.3.) Add this sentence to the above excerpt: However, while Internet slang shortcuts save time for the writer, according to at least one study they take two times as long for the reader to understand.4.) Add this sentence to the above excerpt: Only strict grammarians object, arguing that Internet slang is a degradation of standard usage.
