Climate and Vegetation Zones Geography Binogi app

weather and climate vary lot over the planet in certain places it's always warm swimming weather all year round in other places though it's skiing weather all year round it's cold sometimes very cold some places are dry others are rainy and wet what is it that decides this most importantly it's the sunbeams as they hit the surface of the earth this beam of sunlight reaches the earth close to the equator it hits small area where it gets hot here close to the poles each beam of sunlight is spread out over much larger area which is not heated as much this way the climate becomes warmer the closer to the equator you are will take journey on the earth from the equator to the North Pole to see what different climates we encounter on the way from warm to cold we start in the Congo in Central Africa here we are close to the equator the Sun shines intensely it gets very hot when the air gets warm it becomes lighter and moves higher up in the atmosphere the water vapour in the air goes with it higher up the air gets cooler the water vapour becomes small droplets it starts to rain which it does almost every day so near the equator it's not only warm it's humid too the forests are green and dense and are called rainforests now we move north from the equator large plain areas spread out the vegetation is tall grass and scattered bushes and trees the climate is drier here but rain comes in vast amounts during certain periods of the year rain seasons this is the savanna between them the rainforests and the savanna make up the tropical climate zone now we continue further north the Sun is blazing here it is extremely hot and almost nothing grows how come it's so dry here do you remember that the air rises from the equator when the Sun shines and it gets hot that air can't rise forever when it has reached certain height in the atmosphere it moves south or north instead after while it becomes so cool and heavy it starts to sink toward the earth again then lots of air is pressed to the earth and high pressure areas are created the weather becomes dry and warm such as in the Sahara Desert little further north we reach the Mediterranean here it is dry and very warm in the summer while the winters are mild and bring more precipitation this climate zone with dry hot and long summers and short mild winter is called the subtropical zone further north it's cooler again here we have four distinct seasons spring summer autumn and winter the vegetation is primarily woodland broadleaf or pine trees giant belt of pine forests spread from Scandinavia over Asia and all the way across the North American continent this is the temperate climate zone we finish our journey in the very north it's cold all year round there are areas here where the ice melts in the summer and allows for little vegetation to grow but in the extreme north the ice is there all year round this is the polar climate zone we started our journey in Africa and travelled north through Europe to the North Pole but it looks about the same if we make similar journey from the equator to one of the poles in other parts of the world and therefore we can divide the earth into four climate zones closest to the equator there is the tropical zone it's warm the whole year round and rains lot some distance from the equator there is the subtropical zone with dry and hot summer and short mild winter the temperate zone has four distinct seasons and large forests and in the polar Zone it's cold with almost no vegetation you
