The Hawaiian Islands were formed by such a hot spot occurring in the middle of the Pacific Plate. While the hot spot itself is fixed, the plate is moving. So, as the plate moved over the hot spot, the string of islands that make up the Hawaiian Island chain were formed.

The land area of the state of Hawaii consists of the tops of a chain of emerged volcanic mountains that form 8 major islands and 124 islets, stretching in a 1,500-mile (2,400-km) crescent from Kure Island in the west to the island of Hawaii in the east.

Hawaii’s main volcanoes are “shield” volcanoes, which produce lava flows that form gently sloping, shield-like mountains. A good example is Maunaloa, the most massive mountain on earth, deceptively covering half of Hawaii Island.

The oldest island of Hawaii is Kauai which formed 5.1 million years ago, then Niihau which formed 4.9 million years ago, then Oahu, Hawaii’s third largest island formed 3 and a half million years ago, followed by Molokai which was formed 1 and a half million years, then Maui, Hawaii’s second largest island formed a …

Kilauea volcano (Hawai’i): activity remains unchanged; lava flow continues to feed lava lake. The effusive eruption of the volcano continues and no significant change in activity has occurred since the last update. Laser rangefinder measurements indicate that lava has filled about 220 meters (772 ft) of Halema’uma’u.

Q: Can you see lava in Hawaii now? Yes! The newest and ongoing eruption of the Kilauea volcano started in the Halemaʻumaʻu crater on December 20, 2020. The best way to see lava is from several viewpoints and public viewing areas around the Halemaʻumaʻu crater.

Kilauea – in Hawai’i Volcanoes National Park – is the most active of the five volcanoes that form the Hawaiian islands. Its most recent eruption began December 20, 2020, around 9:30 p.m. local time (7:30 UTC on Monday).

The colder part of a diffusion (incomplete combustion) flame will be red, transitioning to orange, yellow, and white as the temperature increases as evidenced by changes in the black-body radiation spectrum. For a given flame’s region, the closer to white on this scale, the hotter that section of the flame is.

Because the light is outside the range of human vision, it is invisible, so a room illuminated with a black light appears dark. There are many types of black lights, including special fluorescent lamps, LEDs, incandescent lamps, and lasers. These light are not created equal, as each produces a unique spectrum of light.

A “black light” doesn’t produce much visible light, so you’d think maybe it would work as a night light. But what you need to remember is that a black light produces a lot of invisible ultraviolet light. This ultraviolet light can, with continued exposure, result in sunburns. It can damage your eyes.

Blacklight is actually ultraviolet light, slightly higher energy than visible light. When fluorescent surfaces absorb ultraviolet light, they give up that energy in two or more steps. One is in the form of visible light, which is what you see as purple, even when other luminous sources of light are turned off.

Originally Answered: Why do black lights look purple? There is no such thing as “black light”, it is just a name, a label for an energy band of purplish light that occurs in the ultra-violet frequency part of the electro-magnetic spectrum.

Ultraviolet (UV) Light is a proven technology that has been killing mold, fungus, bacteria, and viruses since the beginning of time. It’s effective at treating the mold you know about, and can help kill mold, including airborne spores that you can’t see.

In general terms, darkness or dim light stimulates melatonin production and its resultant drowsiness, which enables us to sleep, whereas bright light — whether it is sunlight or artificial light — stems the flow of this sleep-inducing substance, making us more alert.
