  • Why is sea water salty?

    Nobody knows for sure the answer for that question. There are two hypothesises and both of them can be correct. The first one states that the percentage concentration of salt in sea water has always been bigger than in rivers; the second one states – what is more possible – that salt has been collected from rocks and carried to sea by rivers.

  • How does a breakwater work?

    A breakwater is a construction, that protects for example a harbour from waves influence – it breaks them and do not allow them to reach the covered area. It consists of stones, concrete walls or wooden stakes sticking out of water.

  • Where do the ambers come from?

    Amber is a solidified resin of trees, mainly coniferous ones. Resin needs millions of years to become an amber, so do not count on gaining this beautiful stone from the fresh resin found in the woods after a couple of days.

  • Where is the deepest water of the world?

    The deepest point of ocean is the Mariana Trench. Its depth exceeds 11 kilometres!

  • 
  • Does pirate, buccaneer and privateer means the same?

    Not exactly. Pirates, sailing on the ships or boats, attacked other ships or coasts. Buccaneers have also been pirates, but they served the ruler, who wanted to harm the opponent fleet without spending any money. The ruler allowed buccaneers to rob or kill with no punishment and keep part of the loot.

  • What does „mayday” mean?

    Mayday is an announcement of direct threat to life, used in the air or at the sea. It derives from French m'aidez, which means „help”. When there’s a life threat, the announcement is repeated three times and ship hallmarks are made, describing its position and the reason for the hallmark proceeding.

  • Why does fish can’t fly?

    Some of them can! Fish do not have wings, it’s obvious, but there are some bony fish that have developed pelvic fins in such a way that they can slide over the water waves; bow waves formed by ships, knock this strange fish out in the air. Then they soar like birds!

  • 
  • Why is the water blue?

    Water is in fact most often blue, but we can also observe its other colours. Coastal ocean waters are almost always greenish, because they contain more organic matter disturbing the sunlight in such a way, that reflected light waves are of green and yellow light. Microscopic marine plants also influence the colour of water.

  • Which of the seas is the warmest one?

    The temperature of the Red Sea surface waters reaches even 32°C. You can swim in it just like in warm, though oversalted soup!
