Plastistone
Plastistone is the umbrella term for rocks that have fused with plastic. At the end of 2023 there were numerous sightings of green-colored plastic seemingly melted to rocks. It forms from plastic that floats through the ocean and melts to the rocks over time. So far, the stone has appeared on 5 continents. It was recently spotted in March 2023 on the Brazilian remote island of Trindade and has been seen in Hawaii Hawaii ( ; ) is an island U.S. state, state of the United States, in the Pacific Ocean about southwest of the U.S. mainland. One of the two Non-contiguous United States, non-contiguous U.S. states (along with Alaska), it is the only sta ... a decade before.

Trindade And Martim Vaz
Trindade and Martim Vaz (, ) is an archipelago located in the South Atlantic Ocean about east off the coast of the Brazilian state of Espírito Santo, of which it forms a part. The archipelago has a total area of and a navy-supported research station of up to 8 persons. The archipelago consists of five islands and several rock (landform), rocks and stack (geology), stacks; Trindade is the largest island, with an area of ; about east of it are the tiny Martim Vaz islets, with a total area of . The islands are of volcanic origin and have rugged terrain; the date of last eruption in the island is unknown, but occurred on the southeastern tip of the island at Vulcão de Paredão. They are largely barren, except for the southern part of Trindade. They were discovered in 1502 by Portuguese explorer Estêvão da Gama (c. 1470), Estêvão da Gama and stayed Portuguese until they became part of Brazil at its Independence of Brazil, independence in 1822. From 1895 to 1896, Trindade was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine Plastic Pollution
Marine plastic pollution is a type of Water pollution, marine pollution by Plastic pollution, plastics, ranging in size from large original material such as bottles and bags, down to microplastics formed from the Fragmentation (cell biology), fragmentation of plastic material. Marine debris is mainly discarded human rubbish which floats on, or is suspended in the ocean. Eighty percent of marine debris is Marine debris#Nurdles and plastic bags, plastic. Microplastics and nanoplastics result from the breakdown or photodegradation of plastic waste in surface waters, rivers or oceans. Recently, scientists have uncovered nanoplastics in heavy snow, more specifically about 3,000 tons that cover Switzerland yearly. It is approximated that there is a stock of 86 million tons of plastic marine debris in the worldwide ocean as of the end of 2013, assuming that 1.4% of global plastics produced from 1950 to 2013 has entered the ocean and has accumulated there. Global consumption of plasti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaii
Hawaii ( ; ) is an island U.S. state, state of the United States, in the Pacific Ocean about southwest of the U.S. mainland. One of the two Non-contiguous United States, non-contiguous U.S. states (along with Alaska), it is the only state not on the North American mainland, the only state that is an archipelago, and the only state in the tropics. Hawaii consists of 137 volcanic islands that comprise almost the entire Hawaiian Islands, Hawaiian archipelago (the exception, which is outside the state, is Midway Atoll). Spanning , the state is Physical geography, physiographically and Ethnology, ethnologically part of the Polynesian subregion of Oceania. Hawaii's ocean coastline is consequently the List of U.S. states and territories by coastline, fourth-longest in the U.S., at about . The eight main islands, from northwest to southeast, are Niihau, Niihau, Kauai, Kauai, Oahu, Oahu, Molokai, Molokai, Lanai, Lānai, Kahoʻolawe, Kahoolawe, Maui, and Hawaii (island), Hawaii, a ...

Rocks
In geology, rock (or stone) is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its chemical composition, and the way in which it is formed. Rocks form the Earth's outer solid layer, the crust, and most of its interior, except for the liquid outer core and pockets of magma in the asthenosphere. The study of rocks involves multiple subdisciplines of geology, including petrology and mineralogy. It may be limited to rocks found on Earth, or it may include planetary geology that studies the rocks of other celestial objects. Rocks are usually grouped into three main groups: igneous rocks, sedimentary rocks and metamorphic rocks. Igneous rocks are formed when magma cools in the Earth's crust, or lava cools on the ground surface or the seabed. Sedimentary rocks are formed by diagenesis and lithification of sediments, which in turn are formed by the weathering, transport, and deposition of existin ...

Artificial Stone
Artificial stone is a name for various synthetic stone products produced from the 18th century onward. Uses include statuary, architectural details, fencing and rails, building construction, civil engineering work, and industrial applications such as grindstones. History One of the earliest examples of artificial stone was Coade stone (originally called ''Lithodipyra''), a ceramic created by Eleanor Coade (1733–1821), and produced from 1769 to 1833. Later, in 1844, Frederick Ransome created a Patent Siliceous Stone, which comprised sand and powdered flint in an alkaline solution. By heating it in an enclosed high-temperature steam boiler the siliceous particles were bound together and could be moulded or worked into filtering slabs, vases, tombstones, decorative architectural work, emery wheels and grindstones. This was followed by Victoria stone, which comprises three parts finely-crushed Mountsorrel (Leicestershire) granite to one of Portland cement, mechanically mixed an ...

Plastics And The Environment
Plastics are a wide range of synthetic or semisynthetic materials composed primarily of polymers. Their defining characteristic, plasticity, allows them to be molded, extruded, or pressed into a diverse range of solid forms. This adaptability, combined with a wide range of other properties such as low weight, durability, flexibility, chemical resistance, low toxicity, and low-cost production, has led to their widespread use around the world. While most plastics are produced from natural gas and petroleum, a growing minority are produced from renewable resources like polylactic acid. Between 1950 and 2017, 9.2 billion metric tons of plastic are estimated to have been made, with more than half of this amount being produced since 2004. In 2023 alone, preliminary figures indicate that over 400 million metric tons of plastic were produced worldwide. If global trends in plastic demand continue, it is projected that annual global plastic production will exceed 1.3 billion tons by ...
