CLIMATE DETAILS


 What is climate ?

While the weather changes every day and a hot and humid day can be followed by a rainy one, the climate of a region remains the same for a long time. Thus, the summer season at the north sea is generally cooler than in Freiburg and the winter season is rather cold and damp and not as snowy as in the alps. The climate is driven by the sun, which heats up the air and gives rise to winds such as the trade wind. The ocean and the ocean currents also affect world climate, an instance of which can be seen in the way things turn topsy-turvy due to occurrence 'El Nino'. The climate also undergoes long term changes-the last ice age is a good example of this.

How the weather change ?

Unlike climate, weather depends on the seasons and can also change anytime. Meteorologist predict in the evening how the weather will be the next day. The weather is driven by the sun, which heats up the ground and the water surfaces. Evaporated water creates clouds from which thunderstorm build up, and the ensuing bursts of thunder and lightning make us flinch. Every time a cyclone hits the tropical regions, lashing rain sends  people running for cover.

Where does the rain comes from?

Water evaporates when the sun shines on oceans, seas, or wet grounds or when wind blows over them. The water vapour rises up and get converted again into tiny droplets from clouds which are carried here and there by the wind. If they rise further such as on a high mountain crest, they become colder and turn into large raindrops, small ice crystal and hailstones. These are heavy and fall to the ground as rain, and water seeps into the ground. This water return to the sea as ground water, rivers and streams. This cyclical process known as 'water cycle'.

How did we discover that the Earth is round ?


 About 3000 year ago people believe that the earth was flat. But people wondered why ships disappeared at the horizon. Sailor too returned from journeys and were proof that ships did not fall off the edge of the Earth. The simplest explanation was :the Earth must be round.The final proof come in the year 1522 after the expedition of Ferdinand Magellan,Who was the first to sail around the earth.


Why we do not fall from the Earth ?

Gravity is the force of the Earth that attracts every object toward itself. From our perspective this force always act downwords. For a long time people did not believe that the Earth is round then the people 'underneaath"the sphere would have actually fallen down. In 1687,a physicist issac Newton, prooved that the force of gravity always acts towards the center of the Earth.On the Earth,The force of gravitation always acts 'downwords' irrespect of Eskimos in the Artic region, people in Europe or in habbitants of australa.


What is the atmosphere made up of ?

The word 'atmosphere' means a gaseous cover enveloping a planet. With out atmosphere life would have not been possible on the Earth. One fifth of the atmosphere is Oxygen and four-fifth is Nitrogen. Like the earth interior. The atmosphere too is made up of several layers. All animal and planet lived in the lower most layer of the atmosphere called the troposphere. All weather phenomena take place in the troposphere. Even aeroplanes fly in the outer edge of the troposphere. The stratosphere ,the mesosphere, the iono sphere and the exosphere lie above the traposphere.

Children victimization the net became a big concern.

When youths area unit on the online, they’ll be force into one thing unsafe while not a awfully exceptional stretch. precisely once kids banter with others on the online, they don’t comprehend they might be chatting with a unsafe person.

Unlike the benefits of web, There area unit completely different gadgets open nowadays.

Adolescents got to explore things. withal, there area unit folks on the net that area unit basically usuriously potential. Most guards don’t comprehend the risks enclosed once their youths sign onto the net. Prophet Mahound SAW Said: (in this fashion, guards ought to accept the issue their youths do or seeing…)

Watchmen need to raise their kids upon the exercises of Islam by victimization all potential extraordinary methods.

In all honesty, the net will facilitate gatekeepers in such the way if it’s used exactly. withal, guards ought to management their kids in victimization it in spades. And secure them against manhandling this organization.

What is internet

 


What is the Internet ?

The internet is the wider network that allows


computer networks around the world run by companies, governments, universities and other organisations to talk to one another. The result is a mass of cables, computers, data centres, routers, servers, repeaters, satellites and wifi towers that allows digital information to travel around the world.


It is that infrastructure that lets you order the weekly shop, share your life on Facebook, stream Outcast on Netflix, email your aunt in Wollongong and search the web for the world’s tiniest cat.



What is the world wide web?

The web is a way to view and share information over the internet. That information, be it text, music, photos or videos or whatever, is written on web pages served up by a web browser.


Google handles more than 40,000 searches per second, and has 60% of the global browser market through Chrome. There are nearly 2bn websites in existence but most are hardly visited. The top 0.1% of websites (roughly 5m) attract more than half of the world’s web traffic.

Among them are Google, YouTube, Facebook, the Chinese site Baidu, Instagram, Yahoo, Twitter, the Russian social network VK.com, Wikipedia, Amazon and a smattering of porn sites. The rise of apps means that for many people, being on the internet today is less about browsing the open web than getting more focused information: news, messages, weather forecasts, videos and their 



How much energy does the internet use?

The Chinese telecoms firm Huawei estimates that the information and communications technology (ICT) industry could use 20% of the world’s electricity and release more than 5% of the world’s carbon emissions by 2025. The study’s author, Anders Andrae, said the coming “tsunami of data” was to blame.


In 2016, the US government’s Lawrence Berkeley National Laboratory estimated that American data centres – facilities where computers store, process and share information – might need 73bn kWh of energy in 2020. That’s the output of 10 Hinkley Point B nuclear power stations.
