ARE THERE MOUNTAINS AND VOLCANOES UNDER THE SEA..? DO ALL SEAS HAVE TIDES...?

You may have a doubt that are there any mountains and volcanoes under the seas..?


There are thousands of mountains under the sea. All of them are volcanoes, but some of them do not erupt anymore. There is long chain of undersea mountains all the way down the Atlantic Ocean. It is called the Mid-Atlantic Ridge, and is the longest chain of mountains in the world. The highest sea mountains are over 10,000 metres tall.



You may also doubt that do all seas  have tides..?

Tides are caused due to the pull of the  moon, and to a smaller extent, the Sun. In  general, the larger body of water, the more noticeable the tide. The height of the tide depends on the size, shape, and depth of the sea in a given location. In enclosed seas like the Mediterranean, there is hardly any tide at all, because it is surrounded by land on all sides. The rise and fall of the water may be only a few centimetres.
