Time Zones

Hello, today I am going to write about time zones:

-YEAR: is a revolution around the sun. It takes 365 days and a half. Every 4 years there is one day more. It´s measured with calendar.
-DAY: is a rotation on it´s axis. It takes 24 hours and its divided into two 12 hours period. It´s measured with calendar too.
-A.M.: Ante meridiam (before the meridian).
-P.M.: Post meridiam (after the meridian)
-G.M.T.: Greenwich Mean Time
-U.T.: Universal Time.

Now I am going to answer some questions that my teacher have asked me:
 - How many Time Zones divide the earth?
   The Earth has 24 Time Zones. 
  -What is the distance (in degrees) between Time Zones?
 The distance between one Time Zone to the next is 15 seconds longitude.
 -What is the name of the city where  we can find the Prime Meridiam? What is its longitude?
Greenwich, England and it is at 0º longitude.

 The International Date Line (IDL) is an imaginary line on the surface of the Earth, that runs from the north to the south pole. If you want to cross the IDL from east to west it will take you 1 day (24 hours) and you wont be in the same day you will be one day after.
Here are some images of this unit:

Prehistoric Art

Hello, I was a long time without writting, but I am here again. We have finished a unit about geography, and now we have just started History, we have learned about the different stages of human beings and now we are going to learn about Prehistoric Art. Lets start:

Prehistoric Art.
a) Art started with the appearence and dispersion of Homo Sapiens from Africa, Europe, Asia, America and Oceania.
Archeologysts have find four types of Prehistoric art:
· Cupules, rocks carvings and engravings.
· Pictorial imagery, ideomorphs, ideograms or        symbols.
· Cave paintings and drawings.
· Small totemic statuettes known as Venus Figurines,  various forms of zoomorphic, therianthrophic carving   and relief sculptures.
And megalithic art, consisting of the arrengement of  rocks. 

Like we do, prehistoric people represented their belifs and world trough paintings.   
Paintings in the Lascaux Cave were made by brushes made from animal fur. 
Paleolithic artists used five colours: yellow, red, black, white and brown. White is more strange, but it has been seen. 

The cave art of all the prehistoric groups  consisted of five main motif:
  · Human figures, animals, tools and weapons, local maps and   symbols.

 Vase decoration is a typically Neolithic art form. They were decorated with rolled shells and geometrical motifs.

c) 

Lascaux Cave Paintings. 
The Lascaux Cave was discovered by a group of teenagers in September 1940. The cave is in the southwest of France in the village of Montignac. 
It was closed because of enviromental problems and in 1983 the exact replica "Lascaux II" was build a few hundred metres from the original caves. Other wall made art is reproduced in the Centre of Prehistoric Art, located at Le Thot, France. 
Altamira Cave Paintings.
It is located in the North of Spain, near Cantabria. Altamira is famous because of it's vivid rock paintings, featuring drawings and multicoloured cave paintings. 

Seine

Hello!! It's been a long time since I wrote in this blog, but I've returned!!! Well, lets start:
I am going to talk about a river, the river Seine:
 The River Seine is about 445 km long and it is 24m above sea level. It's depth is 8m when flowing through Paris, and it´s flow is very slow therefore it is easily navigable. It is the second longest river in France after the river Loire with a length of 776km. The mouth of the river is located on the English Channel. It is, perhaps,  the best known river in France. 
The river starts just outside Dijon and flows to the North west through Troyes. It continues its journey to Paris, the capital of France. Then goes to Fontainbleau. Before reaching the English Channel, it goes through Rouen.  
Ile Saint Louis is surrounded by the river Seine. This small island is like an oasis in the middle of Paris. Ille Saint Louis is one of the most visited places of Paris, in this island is the famous Cathedral, Notre Dame.  
The name "Seine" comes from the Latin Sequana. Sequana was the goddess of the river Seine. She was represented like a large bronze statue of a woman, draped in a long gown and with a diadem on her head, she stands in a boat shaped like the head of a duck. The statue is now in the Musée archéologique de Dijon.
