Why do sesonal conditions vary in part of the world

Lerok [7]4 years ago

Answer:

Para empezar, la Tierra no es una esfera perfecta. Y cuando gira sobre su eje (una línea imaginaria que atraviesa el mundo desde el Polo Norte al Polo Sur), su rotación se parece más a la de una peonza que a la de una esfera, bamboleándose y desviándose continuamente. Es lo que se conoce como "movimiento polar".

Las mediciones realizadas durante décadas demuestran que, solo durante el siglo XX, el eje de giro se desplazó alrededor de 10 cm por año. Lo que, durante todo el siglo, supone un desplazamiento de más de 10 metros. Ahora bien, ¿a qué se debe exactamente esta deriva?

Un equipo de investigadores de la NASA ha utilizado datos observacionales que abarcan todo el siglo XX y ha conseguido, por primera vez, identificar las causas del desplazamiento. Son tres: la pérdida de masa, principalmente en Groenlandia; el llamado "rebote glacial" y, por último, la convección del manto. El estudio se acaba de publicar en Earth and Planetary Science Letters, y cualquier persona que esté interesada puede acceder a una simulación interactiva de cómo los varios procesos contribuyen al "bamboleo" del eje de rotación terrestre.

'La explicación tradicional - afirma Surendra Adhikari, investigador del Jet Propulsion Laboratory de la NASA y autor principal del trabajo- es que un solo proceso, el rebote glacial, es responsable de este desplazamiento del eje de rotación terrestre. Pero recientemente, muchos investigadores han especulado que otros procesos podrían tener también grandes efectos sobre él. Elaboramos modelos para un conjunto de causas que se consideran importantes para impulsar el movimiento del eje de rotación. Al final no identificamos uno, sino tres conjuntos de procesos que son cruciales. Y la fusión de la criosfera global (especialmente Groenlandia) a lo largo del siglo 20 es uno de ellos".

How did Woodrow Wilson's Fourteen Points differ from the Paris Peace<br> Conference agreements?
RUDIKE [14]

Answer:

The biggest difference between Wilson's Fourteen points and the Paris Peace Conference agreement was on how to deal with the war losses and the socio-economic future of Europe.

Explanation:

Woodrow Wilson did not talk about war repatriation or any 'revenge' upon an enemy nation. Instead he spoke about the rights of people, discussed free trade and an end to hostilities and also discussed the formation of a few borders, especially an Independent Polish State and the future of the Ottoman Empire.

This however, did not go down well with the European powers, who had bared the real cost of the war. The French industry had collapsed under German pressure and the country was looking for millions in repatriation costs.

The Russians were not happy with an Independent 'Polish' State and had their own claim to the region.

Eventually, the 14 points were rejected, which many claim, eventually led to the second world war.
