DESERTS | Educational Videos For Kids

hello friends welcome to a new happy learning video take a look at these images today we’re going to see a place where it’s both really hot and very very cold [Music] and where it hardly ever rains do you know which place it is it’s [Music] the desert deserts are arid places where there often appears to be no life yet they are home to amazing plants and animals which have had to develop incredible abilities in order to survive but what makes a place a desert it’s not the sand no nor is it the heat it’s actually the scarcity of a fundamental liquid water if a place receives an average of centimeters of rainfall per year which is very very little then we say that that place is a desert deserts cover one fifth of our planet [Music] the most important are the sahara desert the arabian desert the australian desert the gobi desert and the atacama desert but there are also two very special deserts because they are frozen the arctic and the antarctic deserts the world’s largest hot desert is the famous sahara desert [Music] here the temperatures can reach 57 degrees celsius during the day now that’s hot but at night they can drop to 10 degrees below zero freezing [Music] this huge temperature change occurs because it’s so dry that the clouds can’t even form and the clouds not only produce rain but also act as a shield they protect us from the heat of the sun’s rays and at night they prevent heat from escaping the few plants in the desert are very special because they have had to adapt to the lack of water in order to live some store all the water they get in their stems like these cacti others extend roots for many many meters until they find some moisture some remain in a dormant state as if they were asleep and when a few raindrops fall they turn the desert into a garden how beautiful although the truth is they don’t last very long the animals that live in the desert are also very interesting look at these camels their humps are full of fat they are like a reservoir of moisture and so they can go for up to 10 days without drinking other animals like this lizard or this snake prefer to hide during the day and come out at night to hunt [Music] deserts are also home to people like nomadic tribes that never stop traveling from one place to another their clothes protect them from the heat and the frequent sandstorms what a hard life [Music] as we said at the beginning there are frozen deserts they are in the polar areas of the arctic and antarctica they are huge expanses of ice where it hardly rains and where it’s very cold moreover did you know that for many months of the year in frozen deserts there is almost no light most plants cannot photosynthesize that’s why there are only mosses and lichens the animals that live in frozen deserts have thick layers of fat and lots of fur or feathers to withstand the cold like these polar bears this arctic fox and these penguins did you know that deserts are growing look at these pictures deforestation fires and water pollution are turning places full of life into dry and barren land where nothing grows anymore where it’s very difficult for life to prosper that’s why happy learning is asking you to take care of the environment don’t waste water and recycle as much as you can to avoid pollution all together we can make sure that deserts do not advance one more centimeter if we do this our planet and all living things will thank us goodbye friends see you in the next video [Music]
