2. what are the processes by which water vapor is produced? 
3. What are the two ways you can take the water after reaching the surface?

Three quarters of the Earth's surface is covered by the waters of the oceans, lakes, rivers, streams and springs. When drilling in the subsurface, usually water can be found. This is just a different depths (groundwater or groundwater).

The process known as "water cycle" is that by which the ocean water evaporates and precipitates on earth, where it is distributed in rivers and lakes, mainly ensuring groundwater recharge. This water is used by plants, animals and man.

Water vapor is produced by evaporation on land and water bodies, and transpiration of living beings. This vapor circulates through the atmosphere and falls as rain or snow. Upon reaching the surface, the water follows two paths:

In amounts determined by the intensity of the rain as well as porosity, permeability, thickness and antecedent soil moisture, some of the water is discharged directly into streams and rivers, where it is absorbed into the oceans and inland water bodies the rest infiltrates into the ground.

Some water is infiltrated soil moisture, and can evaporate directly or penetrate plant roots for transpiration from leaves. The portion of water that exceeds the forces of cohesion and adhesion of soil, filtered down and accumulates in the call saturation zone to form an underground water reservoir, whose surface is called water table.

Under normal conditions, the water level increases as intermittently filling or recharging will, and then declines as a result of continuous drainage gutters are natural springs.

Sulfuric acid is the main link in the chain of production of chemical muchosproductos. Use in chemical synthesis of many drugs, in lafabricación battery, purification of oil in the ácidosulfúrico metallurgy is used to remove the oxide layers formed on the steel and as in the production of synthetic fibers and dyes. It is obtained from the sulphate amonioque used in the manufacture of fertilizers. In ysulfonatos sulfate detergents are used also from the sulfuric acid, is also used in lapurificación of fats and oils. Thus, the sulfuric acid is not sóloresponsable of acid rain. Their uses are very varied and importantes.El sulfuric acid is commercially available in large numbers and purities deconcentraciones. There are two main processes for laproducción sulfuric acid method and the lead chamber process decontacto. The lead chamber process is the oldest of the two processes currently used to produce yes largely consumed lafabricación acid fertilizer. This method produces a relatively dilute acid (62% -78% H2SO4)

 This corresponds to the abstract of a scientific paper for concentrations of carbon dioxide in the atmosphere and how this impacts on global warming

 ABSTRACT. The glasshouse effect caused by atmospheric CO2: a new thermodynamic interpretation: At present times the use of models to simulate and predict the climate change and its consequences on global ecological processes has contributed to a better understanding of the phenomena in several disciplines. However, there is evidence that current models fail to simulate a number of well known climatic changes recorded around the world, which suggests that many of the processes involved in climatic change are still not fully understood. A new thermodynamic interpretation of the atmospheric glasshouse effect caused by CO2 is presented, which is based on the relationship between temperature and heat considered from the corpuscular theory of energy. The activated complex theory used in chemical kinetics is interpreted as probabilistic criteria, applicable therefore not only to the chemical reactions but also to physical interactions. Under this perspective, this article suggests that

This video is great for when you messed with cat

 it costs nothing to see the video, are 5 little minutes

This video is of a pink floyd theme that is very good, not only to hear the song but the lyrics as well and do a few minutes of reflection to think about the children of our country

Here is the letter:

We don't need no education
we don't need no thought control
no dark sarcasm in the classroom
teacher, leave them kids alone
hey!, teacher, leave them kids alone
all in all it's just another brick in the wall
all in all you're just another brick in the wall

(children:)
we don't need no education
we don't need no thought control
no dark sarcasm in the classroom
teacher, leave the kids alone
hey!, teacher, leave us kids alone
all in all you're just another brick in the wall
all in all you're just another brick in the wall

(teacher:)
wrong! do it again
wrong! do it again
if you don't eat your meat, you can't have any pudding
how can you have any pudding if you don't eat your meat?
you! yes, you behind the bike shed
stand still, laddie
you! yes, you behind the bike shed
stand still, laddie

This video made me laugh and so I leave the link to enter and look, it's about the evolution of technology in education
