Hawaiian IslandsThe Hawaiian Islands (Hawaiian: Mokupuni Hawaiʻi) are an archipelago of eight major volcanic islands, several atolls, and numerous smaller islets in the North Pacific Ocean, extending some 1,500 miles (2,400 kilometers) from the island of Hawaiʻi in the south to northernmost Kure Atoll. Formerly called the Sandwich Islands, the present name for the archipelago is derived from the name of its largest island, Hawaiʻi. The archipelago sits on the Pacific Plate.
MauiMaui is the second-largest island in the Hawaiian archipelago, at 727.2 square miles (1,883 km2). It is the 17th-largest in the United States. Maui is one of Maui County's four sizable islands, along with Molokaʻi, Lānaʻi, and Kahoʻolawe. In 2020, Maui had a population of 168,307, the third-highest of the Hawaiian Islands, behind Oʻahu and Hawaiʻi Island. Kahului is the largest census-designated place (CDP) on the island, with a 2020 population of 28,219.
ErosionErosion 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.
VolcanoRupture in a planet's crust where material escapesAugustine Volcano (Alaska) during its eruptive phase on January 24, 2006A volcano is a vent or fissure in the crust of a planetary-mass object that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater.
Sea levelMean sea level (MSL, often shortened to sea level) is an average surface level of one or more among Earth's coastal bodies of water from which heights such as elevation may be measured.
Trade windsThe trade winds, or easterlies, are east-to-west prevailing winds that flow in Earth's equatorial region. The trade winds blow mainly from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere, strengthening during the winter and when the Arctic oscillation is in its warm phase. Trade winds have been used by captains of sailing ships to cross the world's oceans for centuries.
HaleakalāHaleakalā (; Hawaiian: Hawaiian pronunciation: [ˈhɐlɛˈjɐkəˈlaː]), or the East Maui Volcano, is a massive, active shield volcano that forms more than 75% of the Hawaiian Island of Maui. The western 25% of the island is formed by another volcano, Mauna Kahalawai, also referred to as the West Maui Mountains. The tallest peak of Haleakalā ("house of the sun"), at 10,023 feet (3,055 m), is Puʻu ʻUlaʻula (Red Hill).
HardpanIn soil science, agriculture and gardening, hardpan or soil pan is a dense layer of soil, usually found below the uppermost topsoil layer. There are different types of hardpan, all sharing the general characteristic of being a distinct soil layer that is largely impervious to water. Some hardpans are formed by deposits in the soil that fuse and bind the soil particles. These deposits can range from dissolved silica to matrices formed from iron oxides and calcium carbonate.
Rain shadowA rain shadow is an area of significantly reduced rainfall behind a mountainous region, on the side facing away from prevailing winds, known as its leeward side. Evaporated moisture from bodies of water (such as oceans and large lakes) is carried by the prevailing onshore breezes towards the drier and hotter inland areas.
SaproliteSaprolite is a chemically weathered rock. Saprolites form in the lower zones of soil profiles and represent deep weathering of the bedrock surface. In most outcrops, its color comes from ferric compounds.
OrographyOrography is the study of the topographic relief of mountains, and can more broadly include hills, water stream directions and any part of a region's elevated terrain. Orography (also known as oreography, orology, or oreology) falls within the broader discipline of geomorphology. The term orography comes from the Greek: όρος, hill, γράφω, to write.
Volcanic craterA volcanic crater is an approximately circular depression in the ground caused by volcanic activity. It is typically a bowl-shaped feature containing one or more vents. During volcanic eruptions, molten magma and volcanic gases rise from an underground magma chamber, through a conduit, until they reach the crater's vent, from where the gases escape into the atmosphere and the magma is erupted as lava. A volcanic crater can be of large dimensions and sometimes of great depth.*As an Amazon Associate I earn from qualifying purchases.
