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 ...

Mauna Kea
Mauna Kea ( or ; ; abbreviation for ''Mauna a Wākea''); is a dormant volcano on the island of Hawaii. Its peak is above sea level, making it the highest point in the state of Hawaii and second-highest peak of an island on Earth. The peak is about higher than Mauna Loa, its more massive neighbor. Mauna Kea is unusually topographically prominent for its height: its wet prominence is fifteenth in the world among mountains, at ; its dry prominence of is second in the world, only after Mount Everest This dry prominence is greater than Mount Everest's height above sea level of , and some authorities have labelled Mauna Kea the tallest mountain in the world, from its underwater base. It is about one million years old and thus passed the most active shield stage of life hundreds of thousands of years ago. In its current post-shield state, its lava is more viscous, resulting in a steeper profile. Late volcanism has also given it a much rougher appearance than its neighboring v ...

Landslide
Landslides, also known as landslips, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, deep-seated grade (slope), slope failures, mudflows, and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are called submarine landslides. Gravity is the primary driving force for a landslide to occur, but there are other factors affecting slope stability that produce specific conditions that make a slope prone to failure. In many cases, the landslide is triggered by a specific event (such as a heavy rainfall, an earthquake, a slope cut to build a road, and many others), although this is not always identifiable. Causes Landslides occur when the slope (or a portion of it) undergoes some processes that change its condition from stable to unstable. This is essentially due to a decrease in the She ...

Hawi, Hawaii
Hawi ( haw, Hāwī; ) is a census-designated place (CDP) in Hawaii County, Hawaii. The population was 2,268 at the time of the 2020 United States Census. Hawi is situated to the west of the community of Kapaau. Together, they comprise the most densely-populated region in the district of North Kohala. Historically this part of Kohala is significant as the birthplace of Kamehameha I and the location of the Mookini heiau in the Kohala Historical Sites State Monument. The two communities were once busy commercial centers during the operation of the Kohala Sugar plantation. Hawi is the turnaround point for the Ironman World Championship Triathlon. It is the northernmost point on the bicycle leg, where athletes return to the finish line at Kamakahonu in Kailua-Kona. Geography Hawi is located at (20.241917, -155.834013). According to the United States Census Bureau, the CDP has a total area of , all of it land. The climate of the city is tropical, with temperatures staying betwe ...

Kingdom Of Hawaii
The Hawaiian Kingdom, or Kingdom of Hawaiʻi ( Hawaiian: ''Ko Hawaiʻi Pae ʻĀina''), was a sovereign state located in the Hawaiian Islands. The country was formed in 1795, when the warrior chief Kamehameha the Great, of the independent island of Hawaiʻi, conquered the independent islands of Oʻahu, Maui, Molokaʻi and Lānaʻi and unified them under one government. In 1810, the whole Hawaiian archipelago became unified when Kauaʻi and Niʻihau joined the Hawaiian Kingdom voluntarily. Two major dynastic families ruled the kingdom: the House of Kamehameha and the House of Kalākaua. The kingdom won recognition from the major European powers. The United States became its chief trading partner and watched over it to prevent other powers (such as Britain and Japan) from asserting hegemony. In 1887 King Kalākaua was forced to accept a new constitution in a coup by the Honolulu Rifles, an anti-monarchist militia. Queen Liliʻuokalani, who succeeded Kalākaua in 1891, trie ...

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 the pro-United States led 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.

Kamehameha I
Kamehameha I (; Kalani Paiea Wohi o Kaleikini Kealiikui Kamehameha o Iolani i Kaiwikapu kaui Ka Liholiho Kūnuiākea; – 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 Paiea 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. Kamakau believes this i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
County (United States)
In the United States, a county is an administrative or political subdivision of a state that consists of a geographic region with specific boundaries and usually some level of governmental authority. The term "county" is used in 48 states, while Louisiana and Alaska have functionally equivalent subdivisions called parishes and boroughs, respectively. The specific governmental powers of counties vary widely between the states, with many providing some level of services to civil townships, municipalities, and unincorporated areas. Certain municipalities are in multiple counties; New York City is uniquely partitioned into five counties, referred to at the city government level as boroughs. Some municipalities have consolidated with their county government to form consolidated city-counties, or have been legally separated from counties altogether to form independent cities. Conversely, those counties in Connecticut, Rhode Island, eight of Massachusetts's 14 counties, and Alaska ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sweet Potato
The sweet potato or sweetpotato (''Ipomoea batatas'') is a dicotyledonous plant that belongs to the Convolvulus, bindweed or morning glory family (biology), family, Convolvulaceae. Its large, starchy, sweet-tasting tuberous roots are used as a root vegetable. The young shoots and leaves are sometimes eaten as Leaf vegetable, greens. Sweet potato cultivars, Cultivars of the sweet potato have been bred to bear tubers with flesh and skin of various colors. Sweet potato is only distantly related to the common potato (''Solanum tuberosum''), both being in the order Solanales. Although darker sweet potatoes are often referred to as "yams" in parts of North America, the species is not a yam (vegetable), true yam, which are monocots in the order Dioscoreales. Sweet potato is native to the tropical regions of the Americas. Of the approximately 50 Convolvulaceae#Genera, genera and more than 1,000 species of Convolvulaceae, ''I. batatas'' is the only crop plant of major importance—some o ...

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 continental drift, 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 Genetics, genetic changes as they become subjected to different Natural selection, selective pressures, experience genetic drift, and accumulate different mutations in the separated populations' gene pools. The barriers prevent t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecosystem
An ecosystem (or ecological system) consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and microbes. Ecosystems are controlled by external and internal factors. External factors such as climate, parent material which forms the soil and topography, control the overall structure of an ecosystem but are not themselves influenced by the ecosystem. ...

Tsunami
A tsunami ( ; from ja, 津波, lit=harbour wave, ) 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 other 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 ...
