The document summarizes information about the Earth, including its interior structure, tectonic plates, continents, and earthquakes and volcanoes. It describes the lithosphere and two types of crust. It explains tectonic plates and lists the seven major plates. It discusses continental drift and the movement of continents over time. It provides brief descriptions of volcanoes and earthquakes, including what causes them and examples of volcanic eruptions and earthquake damage.

Harry Ball was born in 1995 in Donostia, Spain. His parents, Diana Lindsay and Philip Ball, are English. He enjoyed playing football and played for Añorga football team. His parents' work involved education projects, so they had to move to Doha, Qatar where this document shows photos Harry sent home. The photos show scenes of their life in Doha like their apartment, areas around the city, cultural sites, shopping malls, sports activities, and Harry's school.
The document outlines the history of sound recording technology from 1877 to 2010, including key inventions like the phonograph in 1877, tape recorders in the 1920s, cassette tapes and compact discs in the 1960s and 1980s, mp3s and digital music in the late 20th century. Modern listening habits using technologies like mp3s, CDs, and digital music are common today, though over 100 years ago there was no means to record and replay sound.

1. 1. Taula diagonalean
tolestu eta triangelu
forma geratuko da.
2. Berriro ere,
era berean
tolestu
eta forma bera
geratuko da
baina txikiagoa.
3. Gero, bi ertzeak barrurantz tolestu behar dira, karratu
forma geratuz.
2. 4. Orain, erdidik
tolestu lauki
zuzenaren forma
emanez.
5. Ondoren, erditik tolestu eta karratu forma geratuko
zaizu.
6.Azkenik, marratik
moztu artazien
laguntzarekin.
4. GRANADAKO ALHANBRA
Alhanbra munduko monumenturik miretsienetako bat da,
musulmanek utzitako aztarna garrantsitzuenetako bat. XIV.mendean
sortu zen eta hitz hau (Alhanbra) musulman hitz batetik dator
gogorleku gorria (fortaleza roja) esanahia duelarik. Honen arrazoia
bertan lanean ari ziren langileen aizkorak eguzkiarekin zuten kolore
gorrixka eta gauetan egiten ziren sute txikiak dira.
Alhanbran matematika asko erabiltzen da, marrazkiak,
eskulturak eta eraikinen forma guztietan (ateak, leihoak...).
Arabiarren erilijioak ez zien uzten animalien eta pertsonen marrazkiak
egiten, beraz, mosaiko geometrikoak erabili zituzten eraikin, lorategi
eta patio guztien apainketarako. Esaterako, hamazazpi simetria mota
ezberdin daudela ikusi izan da, naturan mineralizazioan dauden
guztiak hain zuzen ere. Hortaz gain mosaikoetan bost forma
desberdin daudela ere konprobatu da: erronboa, karratua,
paralelogramoa, hexagonoa eta angeluzuzena. Baina formetaz gain
koloreek ere garrantzi handia dute eta bien loturari esker, Alhanbra
edertasunaren sinbolotzat hartzen da. Horrela, garai batetan errege
Nazariak bizi ziren leku hartara gaur egun bisitari ugari iristen dira.
Materialei so eginez, esan beharra dago, Alhanbra hain eraikin handia
izanik, materialak askotarikoak direla, baina ugarienak zura,
zeramika beiraztatua eta igeltsua direla. Material apalak eta arinak
direnez, aberastasun horren gabezia estaltzeko dekorazioa eta
apaingarri oso ugariak eta landuak erabili zituztela esan ohi da. Zura
normalean ateetan eta sabietan kokatzen ziren, Siria eta
Mesopotamiako sortaldeko eragina bere eginez. Andalustarrek
(eraikuntza lanetako maisuek), mosaikoen teknika eta apainketa ikasi
zuten, gaur egun erabiltzen ditugun azulejoen aurrekariak izango
zirelarik, gerora, behe-ohol eta hormetan erabiliko genituen arren.
Alhanbrako patiorik garrantzitzuena (el patio de los leones) da eta
bertan ere, beste modu batean izan ez litekeen bezala, forma
5. matematiko asko daude. Badirudi irudi horiek guztiak matematikako
problema konplexu bat konpontzeko daudela bertan.
Geometria eta aritmetika menderatzea ezinbesteko abilezi izan zen
monumento zoragarri honen arkitektura lanak egiteko. Azuleju-
estalgarrietan geometria ereduak erabiltzean, gangetako mokarabeak
(igeltsuz edo zurez egindako albeolo esferiko eta prismatikoetan
adibidez). Bestalde hiru dimentsioen efektuekin aberastuta, ura eta
argiaren jakinduria bertan oso ondo erabili izan dira.
