Study Notes
Ocean Basins
- Ocean basins cover approximately 70% of Earth's surface and hold most of the planet's water.
- These regions are situated below sea level and contain various underwater features.
Oceanic Ridges
- Formed when tectonic plates diverge, creating gaps for magma from the mantle to rise.
- Magma solidifies upon cooling, generating a new layer of ocean crust.
- Oceanic ridges are continuous submarine mountain chains and the largest features in ocean basins.
Abyssal Hills
- Raised features in ocean basins that rise from deep ocean floors.
- Typically grow to about 500 feet in height and a few miles in width.
- Formed mainly through volcanism and block faulting, with the influence of spreading rates.
Guyots
- Submerged volcanic mountains with flat tops, shaped by erosion from waves and other processes.
- Differ from seamounts as guyots once reached the surface before being eroded away.
Seamounts
- Large submerged volcanic mountains that rise from the ocean floor, can reach heights of up to 10,000 feet.
- Seamounts never emerged above sea level, retaining their mountain shape.
Evolution of Ocean Basins
- Ocean basins have changed over geologic time, influenced by the movement of tectonic plates for approximately 200 million years.
- The breakup of the supercontinent Pangaea initiated recent ocean basin growth.
- The oldest oceanic crust is found in the western equatorial Pacific, near the Mariana Island arc.
Age of Ocean Floors
- The Pacific Ocean floor's crust formed during seafloor spreading, linked to historical patterns of ridges and tectonic activity.
- The western Philippine Sea floor developed between 60 and 35 million years ago, with new formations occurring from 30 million years ago.
Communication
History and Importance of Language
- The study of language history offers insights into how languages evolve over time, their interconnections, and their impacts on culture and society.
- Language is a crucial part of cultural identity, serving as a means to express ideas, emotions, and experiences.
- Language facilitates communication, knowledge sharing, and community building among individuals.
Languages in the Philippines
- The Philippines is one of the countries with the highest number of dialects and languages, with over 400 distinct languages across more than 7,000 islands.
- Each region has its own languages or dialects, leading to challenges in communication among different groups.
Periods of Language Influence in the Philippines
Spanish Colonial Period
- The Spanish colonization lasted for over 300 years, during which Spanish was the primary language of propaganda and nationalism.
- The Propaganda Movement emerged, led by figures such as Dr. Jose Rizal, Graciano Lopez, Juan Luna, and Antonio Luna, igniting a sense of national pride.
- Dr. Rizal emphasized the importance of language in fostering understanding and unity among Filipinos.
American Colonial Period
- The American occupation introduced the concept of education, contrasting the Spanish approach.
- English was chosen as the medium of instruction in public schools; Thomasites (American soldiers) were the primary teachers.
- Despite English being the main language of instruction, vernacular languages continued to serve as auxiliary languages in education.
Japanese Occupation Period
- During the Japanese occupation, strict media controls prompted Filipinos to strengthen their use of native languages amidst language policy challenges.
- The use of native languages, particularly Tagalog, was emphasized in schools, leading to an increase in local literature.
- Japanese authorities attempted to eliminate American influence by declaring Tagalog and Japanese as official languages through Military Order No. 13.
