Известняки используются:
-в строительстве: как облицовочный камень, для производства извести и тд.
-в стекольной промышленности
-в металлургии (в качестве флюсов)

андрейN1: стекло из песка

kukish1: Известняк для стекольной промышленности используется как источник окиси и кальция для стекловарения. Оксид кальция, получаемый из известняка, способствует силикатообразование, существенно облегчает варку и светопропускаемость

Read the text below and decide if the statements 1-8 are True or False according to the text.
Who are Teenagers?

It was a popular British comedian Harry Enfield who perfectly captured the essence of those difficult teenage years in his character “Kevin the Teenager”. On the eve of his 13th birthday, Kevin and his parents were counting down the seconds till midnight, when the birthday boy began to change before everybody’s eyes. His hair became long and greasy; his skin broke out in spots; his clothes became scruffy and ill-fitting and he lost his ability to speak properly. “I hate you. You are ruining my life” – that’s what he shouted. Frankly speaking, isn’t it a recognizable picture?
The teens really care about the way they look. Many of them believe if a person doesn’t follow fashion, he won’t be in the centre of attention. That’s why they try to wear trendy clothes not be on the other side of popularity. To be popular, in their opinion, means to look perfect – have the perfect clothes, the perfect hair style and the perfect face. The opinion of their peers matters a lot for them.
The desire to be on equal terms with others explains their hanging out with friends. If they are not involved in any activity, they will feel a bit stressed out. Talking with friends on the phone, participating in sport competitions, concerts, student governments are widely spread among them.
In the 21st century, the country of new technologies, teenagers spend tremendous amount of time surfing the Internet, playing computer games. They are so addicted to playing them. Not for nothing they got the name of the ‘thumb generation’. In this connection, a new tendency of exchanging games, discs with music or films appeared. Teenagers feel necessity for meeting peers with the same interests and preferences. Thus, a lot of clubs as another form of socializing in many countries are set up.
If you enjoy dancing, you may join a dancing club. If you are keen on technology, join a technology club etc. At the same time, a lot of interesting teens’ organizations like Boy Scouts or Plast were set up. Together with clubs they help them to enrich teenagers’ world, to develop their intelligence and practical skills, to share their interests and to learn from each other. They have fun being together. Being in a group is like living a real life for them. So let them enjoy this life and be happy.
