One driving motive was the hunt for wealth and luxury goods (gold, spices, silks, etc.); as for technological advances, a star map is an example that comes to mind.
Respuesta: Los glaciares causaron la erosión
Explicación: La deriva continental era una teoría que explicaba cómo los continentes cambian su ubicación en la superficie terrestre. Propuesta en 1912 por Alfred Wegener, un geofísico y meteorólogo, la deriva continental también aclaraba por qué se encuentran fósiles de animales y plantas parecidos, así como formaciones rocosas similares, en distintos continentes.
La teoría de la deriva continental
Wegener pensaba que todos los continentes estuvieron una vez unidos formando un "Urkontinent" antes de separarse y desplazarse hacia sus posiciones actuales. Sin embargo, los geólogos rechazaron rotundamente la teoría de Wegener tras publicar los detalles en un libro de 1915 titulado "El origen de los continentes y océanos." Parte de la oposición se debía a que Wegener no contaba con un modelo adecuado que explicara cómo se movían los continentes.
Though I'm not drafting the two paragraphs, I can provide details about one specific case: Gibbons v. Ogden involved a federally issued permit versus a state (NY) issued permit for navigating New York waterways. The Marshall court reinforced Article VI (Supremacy), asserting that federal law overrides state law, while also bolstering the Commerce Clause's interpretation—that commerce encompasses not just the exchange of goods but also their transportation. This established that national Congress holds the exclusive power to regulate interstate commerce, thereby reinforcing federal authority over state governance. This case, among others, influences the understanding of federalism concerning its powers, rights, and responsibilities.
Initially, there was Humanism during the Renaissance. The curriculum focused on liberal studies, including grammar, poetry, rhetoric, history, politics, and moral philosophy. There was a belief that engaging with classical works would lead to a virtuous and balanced life. The emphasis was placed on human rather than divine concerns, gathering knowledge from sources rather than adhering to tradition, and much of life was dedicated to the study and practice of classical knowledge, opposing the scholasticism prevalent in medieval education.
