When visiting schools and museums our Street Scientists often get asked a variety of questions from curious children. Here are the answers to some of our favourite questions!

This week, we’re answering questions on Marine Biology and Oceanography, ahead of World Ocean Day next Monday.<\/h5>\n\n\n\n

How do they (fish) breath under water?<\/h3>\n\n\n\n

-asked by Maisie, 9, from Kells Lane Primary School<\/em><\/p>\n\n\n\n

Fish can breathe under water because they have lungs that are adapted to work under water. These are called gills. Gills are feathery organs full of blood vessels, fish use them to take up oxygen that is dissolved in the water. Oxygen is taken up through the thin walls of the gills and the travels into the cells in the body. However, there are some mammals that are mistaken as fish, such as whales and dolphins. They are just like us and they need to breathe air to survive. Therefore, we often see them swimming into the surface and take up some oxygen from the air.

What is the fastest fish in the world?<\/h3>\n\n\n\n

-asked by Isobel, 11, from Marden Bridge Middle School<\/em><\/p>\n\n\n\n

The fastest current known fish is the sailfish<\/strong>, it can swim at speeds of up to 68 miles per hour which is around the same speed as cars travel up the motorway!\u00a0

How are waves formed?<\/h3>\n\n\n\n

-asked by James, 10, from Ravenswood Primary School<\/em><\/p>\n\n\n\n

Most waves are formed by wind blowing over the top of the sea. The stronger the wind the bigger the waves! However there are a couple of different types of wave that aren\u2019t formed by the wind for example the tides are actually a form of wave, which are formed by the gravitational attraction of the sun and the moon on the water. Also tsunamis are a type of wave that is formed by under water earthquakes or eruptions! \u00a0

How big is the sea?<\/h3>\n\n\n\n

-asked by Iyla, 7, from Grace Darling Primary School<\/em><\/p>\n\n\n\n

The\u00a0sea\u00a0covers about 71% of the world\u2019s surface <\/strong>and although\u00a0it is all connected it is usually\u00a0split into\u00a05 oceans called:\u00a0The Pacific, the Atlantic (this is the ocean the UK\u00a0is in), the Indian, the\u00a0Antarctic\u00a0and the Arctic ocean.\u00a0All combined that is 1.3 billion cubic km<\/strong> of water, that\u2019s about\u00a03.47 Quadrillion swimming pools\u00a0which is 462,667 swimming pools for every person living on the planet!\u00a0The\u00a0Atlantic ocean\u00a0where we are is the second biggest ocean in the world and if you tried to swim from here to America it would take you\u00a050 days if you\u00a0swam\u00a0non stop.\u00a0The deepest bit of the ocean is called the Mariana trench\u00a0and it is 11,034 metres deep\u00a0that\u2019s more than mount\u00a0Everest\u00a0which is the highest mountain in the world, it\u2019s so deep that only 3 people have ever been there (that\u2019s\u00a0fewer\u00a0than have been to the moon).\u00a0
