Answer:When scientists focus on climate from before the past 100-150 years, they use records from physical, chemical and biological materials preserved within the geologic record. Organisms (such as diatoms, forams and coral) can serve as useful climate proxies. Other proxies include ice cores, tree rings, and sediment cores.

Answer:

4. Colonización portuguesa de Brasil

2010

Por Amelia Meyer

821

Aunque estuvo habitado durante mucho tiempo por tribus y asentamientos prehistóricos, Brasil experimentó un tipo de habitación completamente nuevo durante el siglo XVI. En abril de 1500, los portugueses llegaron a las costas bahianas del río Buranhém, bajo la dirección de Pedro Alvares Cabral. Estos documentaron haber visto a habitantes indígenas al desembarcar en la playa, quienes los recibieron con ofrendas de paz de tocados hechos con plumas de loro.

Aunque los marineros portugueses se quedaron solo nueve días, los indígenas pronto quedaron fascinados por las herramientas de hierro utilizadas, la observancia del servicio católico y las bebidas alcohólicas que observaban. Debido a este interés percibido en la religión católica romana, los portugueses asumieron que estos se convertirían rápidamente al cristianismo una vez educados.
