Tectonic Plates-



1-The following video explains how the phenomenon
  transformants plate, and which is one of the three forms of plate tectonics
1- Through the video-
Explains plates Between that this phenomenon occurs transform plate?
2 -Does it describe according to what the video shows, the property damage?



1-R: El fenómeno se produce entre la Placa Pacífico y la Placa Norteamérica, al deslizarse en zig zag, es decir no hay subducción, sino que ambas placas se mueven en un sentido y otro, dando lugar a la conocida Falla de San Andres (California),
2-R: Los efectos que produce en la superficie son de destrucción material, además de victimas, se pueden observar casas y carreteras destruidas.

1-¿What are the main key concepts that identify the process of the water cycle?

¿The reflected solar radiation over the oceans causing atmospheric phenomenon-What?

Evaporación - Condensación- Precipitaciones- formación del curso de agua- agua que se infiltra a través del suelo (Acuífero)- salida al mar, también la evapotraspiración de las plantas hace que estas al transpirar, ese vapor suba a la atmósfera junto con la evaporación formada desde los mares por efecto de la radiación solar y se condense en la baja atmósfera, donde la temperatura disminuye con la altura y se produce la Condensación y proceso de precipitación.


-TRUE OR FALSE-

-Brand with a V or F corresponding option

-La Evapotranspiraciòn es el proceso por el cual, la vegetaciòn al recibir la energìa solar, hace que estas transpiren y ese vapor se eleve a la Atmòsfera para su posterior condensaciòn __V__-

The Water Cycle


The Water Cycle (also known as the hydrologic cycle) is the journey water takes as it circulates from the land to the sky and back again.

The Sun's heat provides energy to evaporate water from the Earth's surface (oceans, lakes, etc.). Plants also lose water to the air (this is called transpiration). The water vapor eventually condenses, forming tiny droplets in clouds. When the clouds meet cool air over land, precipitation (rain, sleet, or snow) is triggered, and water returns to the land (or sea). Some of the precipitation soaks into the ground. Some of the underground water is trapped between rock or clay layers; this is called groundwater. But most of the water flows downhill as runoff (above ground or underground), eventually returning to the seas as slightly salty water. 

WHY ARE THE OCEANS SALTY?


Oceans cover about 70% of the Earth's surface. The oceans contain roughly 97% of the Earth's water supply.
As water flows through rivers, it picks up small amounts of mineral salts from the rocks and soil of the river beds. This very-slightly salty water flows into the oceans and seas. The water in the oceans only leaves by evaporating (and the freezing of polar ice), but the salt remains dissolved in the ocean - it does not evaporate. So the remaining water gets saltier and saltier as time passes.
