Archive for the ‘Plate tectonics and their effects’ Category

Last week when explaining The Earth´s Internal Energy and its effects: Earthquakes, volcanoes, folds, faults and orogenies, a couple of students form 2ºESO A, came up with a very interesting question. In fact, not all the scientist agree with a same answer.

 Why aren’t there any volcanoes in the Himalayas?

Some videos to help you understanding this Internal Geology Topic:

Alfred Wegener: Great Minds ( 5 mins video; do not miss this funny and interesting youtube channel – scishow– )

The evidences for Continental Drift clearly explained (Geographical / Paleonthological / GEological and Paleoclimatic) – 11 mins-

Teacher Feature (MrSerabian) explains in 7 mintues the 3 types of Plate boundaries. I can also recommend his channel to have fun and learn: MrSerabian.

Last but not least, this 7 minutes video with the basics of Plate tectonics (by Isaac Frame). In this video you will find the answer to

A través de la RedBioGeo encuentro la recomendación de este artículo de análisis de José Cervera sobre las repercusiones del terremoto sucedido en Haití en 2010 y que recupero ahora al hilo del suceso en Japón:

Los terremotos no matan gente.

El artículo comienza con estas dos sentencias contundentes:

Los terremotos no matan gente. Lo que mata gente es la pobreza.

José Cervera

A lo largo del texto se pone el acento sobre la medidas preventivas  que se pueden tomar para paliar los daños basándonos en el contenido científico para el cual es imprescindible el conocimiento de la geología.

This is another one of those good lessons online to learn Earth science, this one is about Earthquakes explaining how and why they happen, what are the seismic waves and what is a seismograph.

Earthquakes- It is an interactive lesson about Earthquakes from the Guardian on line edition

Latest Earthquakes in the World- a good web where the last Earthquakes registered are shown on the map with its magnitude.
