Kohala (mountain)
Kohala is the oldest of five volcanoes that make up the island of Hawaii. Kohala is an estimated one million years old—so old that it experienced, and recorded, the reversal of Earth's magnetic field 780,000 years ago. It is believed to have breached sea level more than 500,000 years ago and to have last erupted 120,000 years ago. Kohala is in area and in volume, and thus constitutes just under 6% of the island of Hawaii. Kohala is a shield volcano cut by multiple deep gorges, which are the product of thousands of years of erosion. Unlike the typical symmetry of other Hawaiian volcanoes, Kohala is shaped like a foot. Toward the end of its shield-building stage 250,000 to 300,000 years ago, a landslide destroyed the northeast flank of the volcano, reducing its height by over and traveling across the sea floor. This huge landslide may be partially responsible for the volcano's foot-like shape. Marine fossils have been found on the flank of the volcano, ...

Volcanic Landslide
A volcanic landslide or volcanogenic landslide is a type of mass wasting that takes place at volcanoes. Occurrences All volcanic edifices are susceptible to landslides, particularly stratovolcanoes and shield volcanoes where landslides are important processes. Volcanic landslides range in size from less than to more than . The largest volcanic landslides on Earth occur from submarine volcanoes and are several times larger than those that occur on land. Submarine landslides with volumes of have occurred in the Canary Islands within the last 43 million years, but the largest submarine landslides could have been up to in volume. Massive submarine landslides have also taken place in the Hawaiian Islands over the last several million years, the largest of which constitute significant portions of the islands from which they originated. Smaller landslides have also been identified at volcanoes on Mars and Venus. Martian landslides reach lengths of and more whereas the largest Venus ...

Kingdom Of Hawaii
The Hawaiian Kingdom, also known as the Kingdom of Hawaiʻi (Hawaiian language, Hawaiian: [kɛ ɐwˈpuni həˈvɐjʔi]), was an Archipelagic state, archipelagic country from 1795 to 1893, which eventually encompassed all of the inhabited Hawaiian Islands. It was established in 1795 when Kamehameha I, then Aliʻi nui of Hawaii, conquered the islands of Oʻahu, Maui, Molokaʻi, and Lānaʻi, and unified them under one government. In 1810, the Hawaiian Islands were fully unified when the islands of Kauaʻi and Niʻihau voluntarily joined the Hawaiian Kingdom. Two major Dynasty, dynastic families ruled the kingdom, the House of Kamehameha and the House of Kalākaua. The kingdom subsequently gained diplomatic recognition from European powers and the United States. An influx of European and American explorers, traders, and whalers soon began arriving to the kingdom, introducing diseases such as syphilis, tuberculosis, smallpox, and measles, leading to the rapid decline of the Native H ...

King Of Hawaii
Kamehameha I established the Hawaiian Kingdom in 1795 after conquering most of the Hawaiian Islands. In 1810, Kaumualiʻi became a vassal of Kamehameha I, who therefore emerged as the sole sovereign of the island chain of Hawaiʻi. His dynasty lasted until 1872, and his Kingdom lasted until 1893, when Queen Liliʻuokalani, of the Kalākaua dynasty, was deposed by pro-United States businessmen who led the overthrow of the Hawaiian Kingdom. The monarchy was officially ended on January 24, 1895, when Liliʻuokalani formally abdicated in response to an attempt to restore the royal government. On November 23, 1993, the Congress passed Public Law 103-150, also known as the ''Apology Resolution'', acknowledging the American role in the overthrow of the Hawaiian monarchy. President Bill Clinton signed the joint resolution the same day. Hawaiian Monarchs (1795–1893) , width=auto, Kamehameha ISpring, 1795 – May 8, 1819 , , c. 1758 Moʻokini Heiau, Kohala, Hawaiʻ ...

Kamehameha I
Kamehameha I (; Kalani Paiʻea Wohi o Kaleikini Kealiʻikui Kamehameha o ʻIolani i Kaiwikapu kauʻi Ka Liholiho Kūnuiākea; to May 8 or 14, 1819), also known as Kamehameha the Great, was the conqueror and first ruler of the Kingdom of Hawaii. The state of Hawaii gave a statue of him to the National Statuary Hall Collection in Washington, D.C., as one of two statues it is entitled to install there. Birth and childhood Paternity and family history Kamehameha (known as Paiʻea at birth), was born to Kekuʻiapoiwa II, the niece of Alapainui, the usurping ruler of Hawaii Island who had killed the two legitimate heirs of Keaweʻīkekahialiʻiokamoku during civil war. By most accounts he was born in Ainakea, Kohala, Hawaii. His father was Keōua Kalanikupuapa'ikalaninui; however, Native Hawaiian historian Samuel Kamakau says that Maui monarch Kahekili II had ''hānai'' adopted (traditional, informal adoption) Kamehameha at birth, as was the custom of the time.

Sweet Potato
The sweet potato or sweetpotato (''Ipomoea batatas'') is a dicotyledonous plant in the morning glory family, Convolvulaceae. Its sizeable, starchy, sweet-tasting tuberous roots are used as a root vegetable, which is a staple food in parts of the world. Cultivars of the sweet potato have been bred to bear tubers with flesh and skin of various colors. Moreover, the young shoots and leaves are occasionally eaten as greens. The sweet potato and the potato are in the order Solanales, making them distant relatives. Although darker sweet potatoes are often known as "yams" in parts of North America, they are even more distant from actual yams, which are monocots in the order Dioscoreales. The sweet potato is native to the tropical regions of South America in what is present-day Ecuador. Of the approximately 50 genera and more than 1,000 species of Convolvulaceae, ''I. batatas'' is the only crop plant of major importance—some others are used locally (e.g., ''I. aquatica'' "ka ...

Geographical Isolation
Allopatric speciation () – also referred to as geographic speciation, vicariant speciation, or its earlier name the dumbbell model – is a mode of speciation that occurs when biological populations become geographically isolated from each other to an extent that prevents or interferes with gene flow. Various geographic changes can arise such as the movement of continents, and the formation of mountains, islands, bodies of water, or glaciers. Human activity such as agriculture or developments can also change the distribution of species populations. These factors can substantially alter a region's geography, resulting in the separation of a species population into isolated subpopulations. The vicariant populations then undergo genetic changes as they become subjected to different selective pressures, experience genetic drift, and accumulate different mutations in the separated populations' gene pools. The barriers prevent the exchange of genetic information between th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecosystem
An ecosystem (or ecological system) is a system formed by Organism, organisms in interaction with their Biophysical environment, environment. The Biotic material, biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal Environmental factor, factors. External factors—including climate—control the ecosystem's structure, but are not influenced by it. By contrast, internal factors control and are controlled by ecosystem processes; these include decomposition, the types of species present, root competition, shading, disturbance, and succession. While external factors generally determine which Resource (biology), resource inputs an ecosystem has, their availability within the ecosystem is controlled by internal factors. Ecosystems are wikt:dynamic, dynamic, subject to periodic disturbances and always in the process of recovering from past disturbances. The tendency of an ecosystem to remain clo ...

Tsunami
A tsunami ( ; from , ) is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Earthquakes, volcanic eruptions and underwater explosions (including detonations, landslides, glacier calvings, meteorite impacts and other disturbances) above or below water all have the potential to generate a tsunami. Unlike normal ocean waves, which are generated by wind, or tides, which are in turn generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water from a large event. Tsunami waves do not resemble normal undersea currents or sea waves because their wavelength is far longer. Rather than appearing as a breaking wave, a tsunami may instead initially resemble a rapidly rising tide. For this reason, it is often referred to as a tidal wave, although this usage is not favoured by the scientific community because it might give the false impression of ...
