Natural Bridge
A natural arch, natural bridge, or (less commonly) rock arch is a natural landform where an arch has formed with an opening underneath. Natural arches commonly form where inland cliffs, coastal cliffs, fins or stacks are subject to erosion from the sea, rivers or weathering ( subaerial processes). Most natural arches are formed from narrow fins and sea stacks composed of sandstone or limestone with steep, often vertical, cliff faces. The formations become narrower due to erosion over geologic time scales. The softer rock stratum erodes away creating rock shelters, or alcoves, on opposite sides of the formation beneath the relatively harder stratum, or caprock, above it. The alcoves erode further into the formation eventually meeting underneath the harder caprock layer, thus creating an arch. The erosional processes exploit weaknesses in the softer rock layers making cracks larger and removing material more quickly than the caprock; however, the caprock itself continues to erod ...

Silang, Cavite
Silang, officially the Municipality of Silang ( tgl, Bayan ng Silang), is a 1st class municipality in the province of Cavite, Philippines. According to the 2020 census, it has a population of 295,644 people. Silang is located in the eastern section of Cavite. It is home to the Philippine National Police Academy, PDEA Academy, and International Institute of Rural Reconstruction head office. With the continuous expansion of Metro Manila, the municipality is now part of the Manila's conurbation which spans southward toward Lipa City. History Pre-Hispanic period The traditional origins of the town are attributed to ten Bornean datus who sailed northward on board balangays and ended in Silang through Taal Lake. Its first settlers were Gat Hingiw, his wife Gat Kaliwanag, and their seven children, who later moved to different parts of the town and established their respective barangays. Gat Pandan stayed in the original community and developed the area. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cavite
Cavite, officially the Province of Cavite ( tl, Lalawigan ng Kabite; Chavacano: ''Provincia de Cavite''), is a province in the Philippines located in the Calabarzon region in Luzon. Located on the southern shores of Manila Bay and southwest of Manila, it is one of the most industrialized and fastest-growing provinces in the Philippines. As of 2020, it has a population of 4,344,829, making it the most populated province in the country if the independent cities of Cebu are excluded from Cebu's population figure. The ''de facto'' capital and seat of the government of the province is Trece Martires, although Imus is the official (''de jure'') capital while the City of Dasmariñas is the largest city in the province. For over 300 years, the province played an important role in both the country's colonial past and eventual fight for independence, earning it the title "Historical Capital of the Philippines". It became the cradle of the Philippine Revolution, which led to the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Provinces Of The Philippines
In the Philippines, provinces ( fil, lalawigan) are one of its primary political and administrative divisions. There are 82 provinces at present, which are further subdivided into component cities and municipalities. The local government units in the National Capital Region, as well as independent cities, are independent of any provincial government. Each province is governed by an elected legislature called the Sangguniang Panlalawigan and an elected governor. The provinces are grouped into seventeen regions based on geographical, cultural, and ethnological characteristics. Thirteen of these regions are numerically designated from north to south, while the National Capital Region, the Cordillera Administrative Region, the Southwestern Tagalog Region, and the Bangsamoro Autonomous Region in Muslim Mindanao are only designated by acronyms. Each province is a member of the League of Provinces of the Philippines, an organization which aims to address issues affecting provi ...

History Of The Philippines (1898-1946)
Earliest hominin activity in the Philippine archipelago is dated back to at least 709,000 years ago. ''Homo luzonensis'', a species of archaic humans, was present on the island of Luzon at least 67,000 years ago. The earliest known anatomically modern human was from Tabon Caves in Palawan dating about 47,000 years. Negrito groups were the first inhabitants to settle in the prehistoric Philippines. By around 3000 BC, seafaring Austronesians, who form the majority of the current population, migrated southward from Taiwan. Scholars generally believe that these ethnic and social groups eventually developed into various settlements or polities with varying degrees of economic specialization, social stratification, and political organization. Some of these settlements (mostly those located on major river deltas) achieved such a scale of social complexity that some scholars believe they should be considered early states. This includes the predecessors of modern-day population centers s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tuff
Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Following ejection and deposition, the ash is lithified into a solid rock. Rock that contains greater than 75% ash is considered tuff, while rock containing 25% to 75% ash is described as tuffaceous (for example, ''tuffaceous sandstone''). Tuff composed of sandy volcanic material can be referred to as volcanic sandstone. Tuff is a relatively soft rock, so it has been used for construction since ancient times. Because it is common in Italy, the Romans used it often for construction. The Rapa Nui people used it to make most of the ''moai'' statues on Easter Island. Tuff can be classified as either igneous or sedimentary rock. It is usually studied in the context of igneous petrology, although it is sometimes described using sedimentological terms. Tuff is often erroneously called tufa in guidebooks and in television programmes. Volcanic ash The material that is expelled in a volcanic ...

Box Canyon
A canyon (from ; archaic British English spelling: ''cañon''), or gorge, is a deep cleft between escarpments or cliffs resulting from weathering and the erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering. A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains, the Alps, the Himalayas or the Andes. Usually, a river or stream carves out such splits between mountains. Examples of mountain-type c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion procee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
