We very often used terms such as "weather" and "climate".But always we clearly understand what it is?And if the weather as we know more, then that is the climate, say not all.Let's try to figure it out.
weather - a state of atmospheric air layer near the surface of the earth over a territory at the time.It depends on many factors, the most diverse and primarily on the processes that occur in the atmosphere.
weather is very changeable during the day can change several times.But if you look closely, watch her for a year, we can see some permanent properties.For example, alternating in sequence with warm and cold weather, by its change of seasons.These features are typical of the area, called climate.In other words, the fact that such a climate, we can say this - it is a long-term weather patterns in the area.
Why is it different?
Since the Earth has a spherical shape, its surface is illuminated by the sun differently.At the poles, the surface of the sun's rays barely heated, sliding and bouncing off the snow, they go back into space.What is the climate of the polar regions - a constant cold, eternal snow and ice.
But in the equatorial region is always hot, there is a maximum coverage, so the sun is always overhead.On both sides of the equator, are areas with the hot conditions, they are called the tropics.In these areas not only always heat but they also are the wettest, since due to the high temperature evaporates much moisture.The abundance of rainfall and hot air contribute to the rapid growth of vegetation.Such a diversity of species of flora and fauna on the planet do not have anywhere else.In addition, to explain in what climates grow tropical forests, it is not necessary, and that's why a lot of the same tropical deserts, it is necessary to clarify.
saturated air during the motion of the equator to the poles is becoming drier.In the tropics there is almost no water, because of this, there are corners of the world, where for several years does not drop a single drop of rain.Under these conditions and formed a desert, in particular, the largest in the world Sahara desert.
What is the climate of the highlands?
much colder in the mountains than on the plains, and these changes are associated with height.The higher on the foot, the climate becomes more severe, as the distance from the Earth's surface temperature is lowered.In this case there is a pattern - if the rise for every thousand meters is becoming colder 6 ° C.
The impact of climate on human life
weather can change several times a day, climate change, too, only much slower, this takes millennia.It is influenced not only by natural factors such as volcanic eruptions, but also the results of human activity.Deforestation, ozone depletion, air pollution - all of this has a negative impact on the Earth's climate.
changes, even the smallest, can lead to major problems for humanity.Changing the location of natural areas in certain regions there is a change of species of flora and fauna, there is the melting of glaciers and ice fields in the Arctic Ocean.All of this will impact not only on people's living conditions, but also on their economic activity.
