Olango Island
The Olango Island Group is a group of islands found in the Central Visayas region of the Philippines. It comprises Olango island and 6 satellite islets namely: Caubian, Camungi, Caohagan, Gilutongan, Nalusuan, Pangan-an, and Sulpa. The island group has a total land area of approximately . It is divided under the jurisdiction of the city of Lapu-Lapu and the municipality of Cordova, Cebu. It lies east of Mactan and is a major tourist destination in Cebu. It is known for its wildlife sanctuary. The entire area is the first declared Ramsar Wetland Site in the Philippines, as recognized in 1994. Geography The Olango Group of islands consists of seven islands. Located east of Mactan Island, Olango Island and its satellite islets lies between the Cebu Strait to the south and the Camotes Sea to the north. To the west is the Hilutangan Channel (which separates it from Mactan Island) while to the east is the Olango Channel (which separates it from Bohol). Land area Olango Islands ...

Cebu
Cebu ( ; ), officially the Province of Cebu (; ), is a province of the Philippines located in the Central Visayas region, and consists of a main island and 167 surrounding islands and islets. The coastal zone of Cebu is identified as a site of highest marine biodiversity importance in the Coral Triangle. Its capital and largest city is Cebu City, nicknamed "the Queen (Catholic) City of the South" having the Second Cardinal, the oldest city and first capital of the Philippines, which is politically independent from the provincial government along with Mandaue and Lapu-Lapu City. The Cebu Metropolitan Area or Metro Cebu is the third largest metropolitan area in the Philippines (after Metro Manila and Metro Davao) with Cebu City as the main center of commerce, trade, education and industry in the Visayas as well as the regional center of Central Visayas. Being one of the most developed provinces in the Philippines, in a decade it has transformed into a global hub for b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mangrove Forest
Mangrove forests, also called mangrove swamps, mangrove thickets or mangals, are productive wetlands that occur in coastal intertidal zones. Mangrove forests grow mainly at tropical and subtropical latitudes because mangrove trees cannot withstand freezing temperatures. There are about 80 different species of mangroves, all of which grow in areas with low-oxygen soil, where slow-moving waters allow fine sediments to accumulate.What is a mangrove forest? National Ocean Service, NOAA. Updated: 25 March 2021. Retrieved: 4 October 2021. Many mangrove forests can be recognised by their dense tangle of prop roots that make the trees appear to be standing on stilts above the water. This tangle of roots allows the trees to handle the daily rise and fall of tides, as most mangroves get flooded at least twice per day. The roo ...

Mactan Island
Mactan is a densely populated island located a few kilometers (~1 mile) east of Cebu Island in the Philippines. The island is part of Cebu province and it is divided into the city of Lapu-Lapu and the municipality of Cordova. The island is separated from Cebu by the Mactan Channel which is presently crossed by three bridges: the Cebu–Cordova Link Expressway (CCLEX), the Mactan–Mandaue Bridge, and the Marcelo Fernan Bridge. The island covers some and has a population of 527,071 as of 2020, making it the nation's most densely populated island. Along with Olango Island Group, the isles are administered by a city and a municipality covering . Mactan–Cebu International Airport is located on the island. Etymology The modern name Mactan descended from an earlier form, ''Manctan''. However, evidence of this earlier form is scant as, even as early as the 17th century, the island was already named Mactan. This form is attested in the original copy of the Philippine Declara ...

Mactan–Cebu International Airport
Mactan–Cebu International Airport (MCIA) is the main international airport serving Metro Cebu and is the main gateway to the Central Visayas region in the Philippines. Located on a site in Lapu-Lapu City on Mactan island, it is the second busiest airport in the Philippines. Opened on April 27, 1966, the airport serves as a hub for Philippine Airlines, and as an operating base for Cebu Pacific, Philippines AirAsia, and Sunlight Air. The airport is managed by the Mactan–Cebu International Airport Authority and operated by the GMR–Megawide Cebu Airport Corporation. History Early years The runway was built by the United States Air Force in 1956 as an emergency airport for Strategic Air Command bombers. It was known back then as the Mactan Air Base. It remained a spartan outpost until the Vietnam War in the 1960s when it became a base for a C-130 unit of the U.S. Air Force. Commercial operations started on April 27, 1966 for domestic flights. It replaced the now close ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Köppen Climate Classification
The Köppen climate classification divides Earth climates into five main climate groups, with each group being divided based on patterns of seasonal precipitation and temperature. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indicates a tropical rainforest climate. The system assigns a temperature subgroup for all groups other than those in the ''A'' group, indicated by the third letter for climates in ''B'', ''C'', ''D'', and the second letter for climates in ''E''. Other examples include: ''Cfb'' indicating an oceanic climate with warm summers as indicated by the ending ''b.'', while ''Dwb'' indicates a semi-Monsoon continental climate, monsoonal continental climate ...

Tropical Monsoon Climate
An area of tropical monsoon climate (occasionally known as a sub-equatorial, tropical wet climate or a tropical monsoon and trade-wind littoral climate) is a tropical climate subtype that corresponds to the Köppen climate classification category ''Am''. Tropical monsoon climates have monthly mean temperatures above in every month of the year and a dry season. The tropical monsoon climate is the intermediate climate between the wet Af (or tropical rainforest climate) and the drier Aw (or tropical savanna climate). A tropical monsoon climate's driest month has on average less than 60 mm, but more than 100-\left(\frac\right). This is in direct contrast to a tropical savanna climate, whose driest month has less than 60 mm of precipitation and also less than 100-\left(\frac\right) of average monthly precipitation. In essence, a tropical monsoon climate tends to either have more rainfall than a tropical savanna climate or have less pronounced dry seasons. A tropical monsoon cl ...

Climate Of The Philippines
The Philippines has five types of climates: tropical rainforest climate, tropical rainforest, tropical monsoon climate, tropical monsoon, tropical savanna climate, tropical savanna, humid subtropical climate, humid subtropical and oceanic climate, oceanic (the latter two are found in higher-altitude areas). The country overall is characterized by relatively high temperature, oppressive humidity and plenty of rainfall. There are two seasons in the country: the wet season and the dry season, based upon the amount of rainfall. This is also dependent on location in the country as some areas experience rain all throughout the year (see ). The warm months of the year are March through October; the winter East Asian Monsoon, monsoon brings cooler air from November to February. May is the warmest month, and January, the coolest. Weather in the Philippines is monitored by the PAGASA (Philippine Atmospheric, Geophysical and Astronomical Services Administration). Rainfall Monsoons ar ...

Equatorial Climate
A tropical rainforest climate or equatorial climate is a tropical climate sub-type usually found within 10 to 15 degrees latitude of the equator. There are some other areas at higher latitudes, such as the coast of southeast Florida, United States, and Okinawa, Japan that fall into the tropical rainforest climate category. They experience high mean annual temperatures, small temperature ranges, and rain that falls throughout the year. Regions with this climate are typically designated ''Af'' by the Köppen climate classification. A tropical rainforest climate is typically hot, very humid, and wet with no dry season. Description Tropical rainforests have a type of tropical climate (with an average temperature of at least in their coldest month) in which there is no dry season—all months have an average precipitation value of at least . There are no distinct wet or dry seasons as rainfall is high throughout the months. One day in a tropical rainforest climate can be very similar ...

Hard Water
Hard water is water that has a high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone, chalk or gypsum, which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates. Drinking hard water may have moderate health benefits. It can pose critical problems in industrial settings, where water hardness is monitored to avoid costly breakdowns in boilers, cooling towers, and other equipment that handles water. In domestic settings, hard water is often indicated by a lack of foam formation when soap is agitated in water, and by the formation of limescale in kettles and water heaters. Wherever water hardness is a concern, water softening is commonly used to reduce hard water's adverse effects. Origins Natural rainwater, snow and other forms of precipitation typically have low concentrations of divalent cations such as calcium and magnesium. They may have small concentrations of ion ...

Alluvium
Alluvium (, ) is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings. Alluvium is also sometimes called alluvial deposit. Alluvium is typically geologically young and is not Consolidation (geology), consolidated into solid rock. Sediments deposited underwater, in seas, estuaries, lakes, or ponds, are not described as alluvium. Floodplain alluvium can be highly fertile, and supported some of the earliest human civilizations. Definitions The present Scientific consensus, consensus is that "alluvium" refers to loose sediments of all types deposited by running water in floodplains or in alluvial fans or related landforms. However, the meaning of the term has varied considerably since it was first defined in the French dictionary of Antoine Furetière, posthumously published in 1690. Drawing upon concepts from Roman law, Furetière defined ''alluvion'' (the French term for al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quaternary
The Quaternary ( ) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS), as well as the current and most recent of the twelve periods of the Phanerozoic eon. It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today); a proposed third epoch, the Anthropocene, was rejected in 2024 by IUGS, the governing body of the ICS. The Quaternary is typically defined by the Quaternary glaciation, the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four succ ...

Plio-Pleistocene
The Plio-Pleistocene is an informally described geological pseudo-period, which begins about 5 million years ago (Mya) and, drawing forward, combines the time ranges of the formally defined Pliocene and Pleistocene epochs—marking from about 5 Mya to about 12 kya. Nominally, the Holocene epoch—the last 12 thousand years—would be excluded, but most Earth scientists would probably treat the current times as incorporated into the term "Plio-Pleistocene"; see below. In the contexts of archaeology, paleontology, and paleoanthropology, the Plio-Pleistocene is a very useful period to which scientists may assign the long and continuous run in East Africa of datable sedimentary layers and their contents (e.g. the Bouri Formation). These contents collectively present a focused view of the continuous evolution of the region's large vertebrates, especially the evolution of some African apes ( hominids) to the earliest hominins; and then the development of the early humans and ...
