The distance to the centre of the Earth has been taken as the volumetric mean radius of the Earth: 6,371km.

iMoviemanual för nybörjare Jag har skapat en manual för nybörjare till appen iMovie. Den tar upp en del av, enligt mig, de viktigaste funktionerna att känna till för att komma igång. Manualen har bilder och beskrivningar för funktionerna i iMovie när man vill skapa en film eller trailer. iMovie rymmer så mycket mer, men har du väl startat, kommer du att själv upptäcka finesser under resan.

Les élèves ont déjà appréhendé en classe la notion de plaques lithosphériques définies en surface par l’activité sismique et volcanique et en profondeur par l’étude de la vitesse de propagation des ondes sismiques. Les notions de lithosphère et d’asthénosphère sont connues.

Blog Animation is a powerful technique that allows you to turn complex ideas or vague concepts into a clear and comprehensive story. However, sometimes it might be easier or less time-consuming to demonstrate something using camera-recorded video instead of recreating a situation using animated objects: a product demo, an exterior site, a manufacturing process, an interview — live action helps showing your audience how something works or what you've achieved.
