plate tectonics:
lithosphere- contains the crust and the upper mantle,

asthenosphere- is the next layer within the mantle, 

mesosphere- were material still flows but at a much slower , 

boundaries : divergent - two tectonics moves away from each other   
convergent- two tectonics push together  transform- two plate slide each other    

solar system : formed 4.6 billon years , 

terrestrial planet- mercury, venus,earth,mars 

Gas giant - jupiter, saturn,uranus,neptune, 

planet: celestial body, constellation:help people to recognize stars , stars : made of hydrogen and helium , galaxy: huge collection of gas

Sandblasting is a practice for excellence in Almeria,
This technique is based on the placement on the ground of an impermeable horizon that can be cane earth thirty 
centimeters thick, over a layer ofmanure two centimeters and finally a layer of sand between ten and twenty 
centimeters.
One of its qualities is that it prevents the rise of the water by capillarity breaking is where the roots of the 
plants are located, allows the use of water which is a great advantage and allows saving water.
The main element of sandblasting is sand.

3.5 billion years old
 embedded in rocks in western Australia: stromatolites(fosilized bacteria)                
Prokaryotes dominated from 3.5 to 2 billion years ago.
 During this time, the first divergence occurred:Bacteria and archeae
5.  First photosynthetic organisms around 3.5 billion years but Oxygen began accumulating in the atmosphere about 2.7 billion years ago. Cyanobacteria are photosynthetic prokaryotes that are still present today → produced oxygen. Sequestered carbon dioxide in organic molecules.
These bacteria changed the Earths atmosphere.
6.  The oldest eukaryotic fossils are ~2 billion years old.
 Symbiotic community of prokaryotes living within larger prokaryotes.

First step in forming sedimentary rock

Written at on English with a size of 1.38 KB.

KARST LANDFORM- A modelling that takes place in limestone masses due to the action of water with dissolved carbon dioxide from the atmosphere.  The CO2 reacts with the calcium carbontae in the limestone adn transforms it into calcium bicarbonate. This is a type of chemical weathering callled carbonatation. The inflitrationof water slowly alter and soddolves the limestone, making the cracks and fissures in the rock and creating lapies, dolines, poljes, galleries and caverns. In the cavities, the dissolves calcium bicarbonate can be transformed back into insoluble carbonate, creating stlactites and stalagmites. JOINTS-Are short, narrow cracks that appear in a rock mass without the cracked blocks moving at all. EROSION- The progressive wearing

Written at on English with a size of 3.71 KB.

Raw materials: three types: raw materials of animal and plant origin, raw materials of mineral origin: non-metallic minerals: are those from which other materials are obtained, including sulfur, rock salt, gypsum and mica, rock are also considered non-metallic raw materials, rock are also considered non-metallic raw materials. Mines: mining refers to the process of extracting raw materials origin. Non-renewable energy sources: are natural resources that are processes to produce energy for domestic purposes and the operation of industries and transport. Two groups: depending on their economic importance, they are classified as tradicional or alternative and depending on whether or not the will run out, they can be renewable or non-renewable.

Characteristics of a good source of fuel :-i) It should have A high energy output per unit mass or volume.

ii) It should be easily available.Iii) It should be easy to store and Transport.Iv) It should be economical.

Sources of energy :-

Conventional sources of energy :- are wood, flowing water& fossil fuels (coal, petroleum, natural gas).

Non conventional sources of energy :- are solar energy, Wind energy, biomass energy, ocean energy (tidal energy, wave energy, ocean Thermal energy), geothermal energy, nuclear energy etc. Some sources of energy Are renewable like sun, wind, flowing water, ocean, wood, biomass etc. Some Sources of energy are non renewable like coal, petroleum and natural gas.
