Sea

The moon and dark stains on it have always interested the people. Galileo Galilley was the first to call these stains “seas”. He was the first to study the Moon with the help of a telescope and perhaps he was very much amazed by the vast smooth fields with the chains of mountines and rages on the Moon’s surface. He even noticed some kind of waves on them but the time passed and these waves did not change their positions. Galliley even then realized that these moon seas were not actually of liquid as they were just valleys. As it turned out later, they consist of basalt or in other words solidified lava which existed there when the Moon was tectonically active.
The names of these seas are of Latin origin and are still used in science in Latin. They occupy nearly 17 per cent of the whole Moon’s surface. They are called maria. The largest seas are - Mare Tranquillitatis, Crisium, Foecunditatis, Nectaris, Nubium, Humorum, Imbrium, and Serenitatis.
So when looking on the moon try to find some of them as people many centuries ago did.

Children and sun

The hot summer sun - are the kids. First of all, it is the main factor in the growth of children, because vitamin D sunlight enhances their work but also the best natural means to combat anemia, as well as the sun speeds up the metabolism, supports the immune system and helps to counter the disease. To sunbathing were really helpful, you need to know how to take. Indeed, sometimes the sun can be very insidious! 
If your child complains of headaches, he had a very red face; it may be signs of sunstroke. This often occurs on hot days. But even on cloudy days, going out into the street, be sure to don’t give kid headdress. Symptoms heliosis often resemble signs of the beginning of an inflammatory disease: baby becomes sluggish (or, conversely, very excited), he raised the temperature. If time does not take action, the child may lose consciousness. 
We need to always remember that heliosis - it defeated the central nervous system. It arises because of the strong head overheating sunlight. In doing so, significant changes in metabolism, which leads to a shortage of oxygen to tissues, violated the function of important organs and systems. 
Put a child in a dark and quiet place. Unfasten clothes or undress it. On the forehead and put his head cold compresses. Come on baby to drink more frequently, preferably water at room temperature with lemon. If the temperature is high, the child has dizziness, nausea, vomiting, he loses consciousness, immediately called an ambulance! To reduce the temperature to use physical methods of cooling the body: rubdown, cool shower, wrapping wet sheets.
