How to create a Temperature Graph


To create a temperature graph, the first thing you have to do is to locate the categories in the graph. In this case, the days of the week and different temperatures.



¡¡Remember!!

*The space between the different data MUST be the same. 
*You MUST keep the same series, which means that if you start counting in twos (15,17,19,21...) you should continue like this until the end. 
🙊You can not write for example 15, 17, 22, 23, 25...🙊


After that, it is time to indicate in your graph the relation between the information. In this case, between the temperature and the days of the week.


To finish with your graph, you just have to join the different points in order, and you will obtain the final version of your temperature graph.

Climate


¡¡Remember!!

Climate is not the same as weather.

Weather is the temperature, precipitation and wind at a particular time and place.

Climate is the typical temperature and precipitation in a particular place BUT over a long period of time.


We can divide the Earth into 3 different climate ZONES depending on the amount of heat each zone receives from the Sun, as you can see in the following picture...


Nevertheless, there are a lot of different climates on the Earth.

For example...... 

-Places near the Equator have a hotter climate than those further from the Equator.
-Mountains have colder climates and coasts have hotter climates.


THE TROPICAL ZONE: Places located in this zone have hot climates

Near the Equator, temperatures are high and it rains a lot. There are a lot of forests
Further from the Equator, it rains less, so there is less vegetation. There are a lot of savannahs.
In places like deserts, it rains less, so there is little vegetation. 


            
     FOREST


       
     SAVANNAH


       
      DESERT


THE TEMPERATE ZONES: There are two temperate zones, and the climates there are temperate, nor too hot nor too cold. 

Climates in these zones vary, and the four seasons are different.

Typical vegetation in these zones is woodland and grassland.


         
         WOODLAND


         
           GRASSLAND


THE POLAR ZONES: There are two polar zones. Places located there, have cold climates with little precipitation, mainly as snow.

Typical vegetation is tundra, where only moss and grasses grow.

The Weather


¡¡Remember!!

The weather is the state of the atmosphere at a particular time and place. The weather often changes. It is determined by temperature, precipitation and wind, and it happens in the troposphere.




TEMPERATURE: The temperature is an important element of the weather for all living things. 

Humans need a warm temperature to live, between 18 and 22ºC.

We measure the temperature in ºC (degrees Celsius), and we use a thermometer for measuring it.



PRECIPITATION: It happens when the water drops in the clouds get bigger and heavier, and fall to the ground. Depending on the temperature, that water can fall as rain, snow or hail.

We measure the precipitation in litres per square metre (l/m2), and we use a pluviometer for measuring it.


WIND: The wind is the air moving in a particular direction and speed. There are different types of wind:

-Breezes (light winds)
-Gales (strong winds)
-Hurricanes (extremely strong winds, destructive winds)

We measure the speed of the wind in (km/h) with an anemometer...... 

  

and its direction with a weather vane.....





Global Warming




As you already know, the Earth is becoming warmer and warmer, but do you know why?

Because of an excessive Greenhouse Effect



As you have seen, the Greenhouse Effect is something good for the Earth. But be careful, an excessive Greenhouse Effect is something dangerous. What does it mean?

Although it is true that the Greenhouse gases act as a barrier to maintain the warmth on the Earth, an excessive increase of those gases make that barrier thicker and thicker

As you have seen in the first video, if that Greenhouse gases barrier becomes thicker, it results impossible for the Earth´s excessive heat to go back to the Universe. As a consequence, the Earth´s temperature increase.

Nowadays, the Earth´s temperature is higher than for example 100 years ago. If it continues increasing........ 

-The North and the South Poles will disappear because of the melting process... 😰



-Some cities near the coast will disappear because the level os the sea will increase... 😣



-Lots of animals and plants will die because of the high temperatures... 😓

Air Pollution & the Ozone Layer




As you already know, air pollution happens when the atmosphere contains too much of one of its gases. Some of these gases come from burning fuel in industries, vehicles and homes. 

Air pollution is a serious problem for the environment. It affects the health of all living things.

Because of this pollution, the ozone layer is becoming thinner

¡¡Remember!!

The Ozone Layer is like a shield that protects us from the harmful rays of the Sun.



If that shield continues becoming thinner and thinner, more and more harmful rays will enter to the Earth in a near future, which is dangerous for plants, animals and humans.
