Hey guys, how are you guys I'm from Abril educa.com And today we're going to talk about the oceans and the seas but these I want to ask you to subscribe to our channel I'll like the video and also Activate antivirus for stay on top of everything we put here on our channel and now let's go to class she's very top good let's start with the oceans the oceans are large expanses of salt water that cover seventy percent of the earth's surface enveloping and also separating continents there are four oceans, the Pacific , the Indian Atlantic,
and the Arctic glacier, so just like the surface of the earth, the bottom of the oceans also have different shapes, with emphasis on the resistance mountain ranges that are called dorsals, guys, that's right there are mountains below in the ocean or as oceanic waters are in constant motion and under the influence of the earth's rotation if I send it the difference in temperature and salinity of the waters causes displacement d and masses of water in the oceans known as the famous sea currents, these movements interfere in the climatic conditions of everyone and can cause periods
of drought or rain on the continent, the warm waters close to the equator die without direction to the poles and the cold waters are displaced in the sense how to deal with the poles to the equator line these sea currents will directly influence our life because it will change it will influence the climate of each Brazilian region and also each region of the world seriously let's talk now about the oceans the Pacific Ocean is located between Asia EA Oceania and America is the largest ocean and also covers about a third and it is also the
deepest with more than 11 thousand meters and what stands out is the Mariana Trench that has there in the Pacific they are around the Pacific there is an area of geological instability called the circle of fire in this arc there is an earthquake tsunami and also volcanic islands and mountain ranges are formed Pacific Ocean has increased its strategic importance commercially and militarily, especially between the countries of Asia, Oceania and the United States, so people look at how even the oceans are extremely strategic for the world economy today, the Atlantic Ocean is located between America, Africa
and Europe and it is the second largest ocean in the world it is divided into the North Atlantic and the transposul and is what bathes the largest number of countries and territories because of the great flow of communication preaching between Europe and America with the Atlantic it has historically assumed great strategic importance right then in the middle of the North Atlantic Ocean so there is a wide submarine mountain range Atlantic worship mountains also the occurrence of volcanic islands in this area So look how interesting there guys this Atlantic ridge a large mountain range that is
in Atlantic Ocean And in addition another ocean that has long contributed to the The Indian Ocean is located between Africa, Asia and Oceania and is the third largest in the world and most of it is located in the southern hemisphere, the Indian Ocean and the departure of many oil tankers from the Middle East and it is much more than a billion people live on the shores of the Indian Ocean important economic activities are developed in its waters an example of this is fishing and also oil exploration finally guys we have the glacial Arctic Ocean is
located in the north of America, Europe and Asia will have low temperatures and will remain icy for a large period of the year in this ocean if the North Pole is located in these areas of the Arctic Ocean there are giant floating ice blocks famous five famous icebergs and This makes it difficult to navigate through Arctic are its recent ice there because of the warming of the waters, new navigation routes were opening and accelerating exploration. the economic in the region Look how interesting there with the melting of these ice is like opening paths that also
open up opportunities to eat right even though their temperatures are always low the arctic region is inhabited by many native peoples to hundreds Dian so all these oceans exist within of our planet earth so we can understand and each one of them has a characteristic and they will vary in the way we humans are going to use these oceans let's talk about something now that will influence the oceans the tides are the tides are the waters of the oceans and suffer constant oscillations and sometimes it just comes, sometimes it comes to the beach for example
when you arrive at the beach you put it on your umbrella very close to the sea because because the tide is set back but the hours go by it happens Maria is going up going up and soon it will take everyone with it the whole family now have you ever wondered why this happens this movement comes with me daily are the materials were created by the gravitational attractions of the sun and moon on the surface of the oceans the level of high tides will call the high tide And low low tide is influenced by the
position of the moon in relation to the earth and the sun the greater oscillations of the tides occur with from Earth to the moon and the sun are aligned ie during the new moon and far away following the galley not talking about the seas the seas are masses of salt water that are located close to the continent or inside these continents the sun presents there smaller depth and size than the oceans also not having a greater variation in the amount of salt than temperature and also in the transparencies of the Waters is basically the seas
is an environment that they dive on the beach right there are three classifications for the seas open sea the inland sea and the ocean closed sea only the open sea can also be called as Marcos ugly is the one that communicates with the ocean through wide passages an example of this is the North Sea that is in the Europe the closed sea can also do nothing like the isolated sea This Sea does not have communication with the ocean or with another sea it is located within the continental lands like a large lake more or less
closed serves as an example of this is the Dead Sea this type of banks Depends on rainfall and river water to maintain the volume of water an interior can also be called the continental sea will communicate with the ocean through straits or channels the Mediterranean sea for example communicates with the Atlantic Ocean pa Gibraltar good guys This was our class for today but before finishing I want to give you a very important message if you are having difficulty with school or you are curious to learn more about all the subjects you study at school click
on this link is that here it is, cool educa.com and take a look at our platform that we can help you very seriously guys I hope you enjoyed it and until next time Hey Hey Hey
