Q: Context: Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced or sinks due to gravity into the mantle. Regions where this process occurs are known as "subduction zones". Rates of subduction are typically in centimeters per year, with the average rate of convergence being approximately two to eight centimeters per year along most plate boundaries., Milwaukee Deep , also known as The Milwaukee Depth , ( 19 35 N 66 30 W ) is the deepest part of the Atlantic Ocean and is part of the Puerto Rico Trench . It has a maximum depth of at least 27,493 feet ( 8,380 m ) . It is just 76.0 miles ( 122.3 km ) north of the coast of Puerto Rico at Punto Palmas Altas in Manati . This ocean floor feature is named for the USS Milwaukee ( CL - 5 ) , a U.S. Navy Omaha class cruiser , which discovered the Milwaukee Deep on February 14 , 1939 with a reading of 28,680 feet ( 8,740 m ) . On August 19 , 1952 , the U.S. Fish and Wildlife vessel Theodore N. Gill obtained a reading of 28,560 feet ( 8,710 m ) at ( 19 36 N 68 19 W ) , virtually identical with the Milwaukee ' s reading . The existence of deep water to the Atlantic Ocean side of the Caribbean has been known for more than a century . One of the area 's earliest soundings was obtained June 12 , 1852 by Lt. S. P. Lee , U.S. Navy brig Dolphin , with a reading of 22,950 feet ( 7,000 m ) at ( 26 32 N 60 06 W ) ., The Caribbean Sea is a sea of the Atlantic Ocean in the tropics of the Western Hemisphere. It is bounded by Mexico and Central America to the west and south west, to the north by the Greater Antilles starting with Cuba, to the east by the Lesser Antilles, and to the south by the north coast of South America., The oceanic trenches are hemispheric-scale long but narrow topographic depressions of the sea floor. They are also the deepest parts of the ocean floor. Oceanic trenches are a distinctive morphological feature of convergent plate boundaries, along which lithospheric plates move towards each other at rates that vary from a few mm to over ten cm per year. A trench marks the position at which the flexed, subducting slab begins to descend beneath another lithospheric slab. Trenches are generally parallel to a volcanic island arc, and about from a volcanic arc. Oceanic trenches typically extend below the level of the surrounding oceanic floor. The greatest ocean depth to be sounded is in the Challenger Deep of the Mariana Trench, at a depth of below sea level. Oceanic lithosphere moves into trenches at a global rate of about 3km/yr., Central America is the southernmost, isthmian portion of the North American continent, which connects with South America on the southeast. Central America is bordered by Mexico to the north, Colombia to the southeast, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America consists of seven countries: Belize, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica and Panama. The combined population of Central America is between 41,739,000 (2009 estimate) and 42,688,190 (2012 estimate)., Hispaniola (Spanish: "La Espanola"; Latin: "Hispaniola"; Taino: "Haiti") is the 22nd-largest island in the world, located in the Caribbean island group, the Greater Antilles. It is the second largest island in the Caribbean after Cuba, and the tenth most populous island in the world., Puerto Rico, (Spanish for "Rich Port") officially the Commonwealth of Puerto Rico ("Free Associated State of Puerto Rico") and briefly called Porto Rico, is an unincorporated territory of the United States located in the northeast Caribbean Sea., Water is a transparent and nearly colorless chemical substance that is the main constituent of Earth's streams, lakes, and oceans, and the fluids of most living organisms. Its chemical formula is HO, meaning that its molecule contains one oxygen and two hydrogen atoms, that are connected by covalent bonds. Water strictly refers to the liquid state of that substance, that prevails at standard ambient temperature and pressure; but it often refers also to its solid state (ice) or its gaseous state (steam or water vapor). It also occurs in nature as snow, glaciers, ice packs and icebergs, clouds, fog, dew, aquifers, and atmospheric humidity., The Atlantic Ocean is the second largest of the world's oceans with a total area of about . It covers approximately 20 percent of the Earth's surface and about 29 percent of its water surface area. It separates the "Old World" from the "New World"., The Pacific Ocean is the largest of the Earth's oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south and is bounded by Asia and Australia in the west and the Americas in the east., Cuba, officially the Republic of Cuba, is a country comprising the island of Cuba as well as Isla de la Juventud and several minor archipelagos. Cuba is located in the northern Caribbean where the Caribbean Sea, the Gulf of Mexico, and the Atlantic Ocean meet. It is south of both the U.S. state of Florida and the Bahamas, west of Haiti, and north of Jamaica. Havana is the largest city and capital; other major cities include Santiago de Cuba and Camaguey. Cuba is the largest island in the Caribbean, with an area of , and the second-most populous after Hispaniola, with over 11 million inhabitants., The Old World consists of Africa, Europe, and Asia, regarded collectively as the part of the world known to Europeans before contact with the Americas. It is used in the context of, and contrast with, the New World (Americas)., Bean is a common name for large seeds of several genera of the flowering plant family Fabaceae (also known as Leguminosae) which are used for human or animal food., A transform fault or transform boundary (also known as a conservative plate boundary, since these faults neither create nor destroy lithosphere), is a type of fault whose relative motion is predominantly horizontal, in either a sinistral (left lateral) or dextral (right lateral) direction. Furthermore, transform faults end abruptly and are connected on both ends to other faults, ridges, or subduction zones. While most transform faults are hidden in the deep oceans where they offset divergent boundaries as series of short zigzags accommodating seafloor spreading, the best-known (and most destructive) are those on land at the margins of tectonic plates. Transform faults are the only type of strike-slip fault that can be classified as a plate boundary., Area is the quantity that expresses the extent of a two-dimensional figure or shape, or planar lamina, in the plane. Surface area is its analog on the two-dimensional surface of a three-dimensional object. Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single coat. It is the two-dimensional analog of the length of a curve (a one-dimensional concept) or the volume of a solid (a three-dimensional concept)., An ocean (the sea of classical antiquity) is a body of saline water that composes much of a planet's hydrosphere. On Earth, an ocean is one of the major conventional divisions of the World Ocean, which covers almost 71% of its surface. These are, in descending order by area, the Pacific, Atlantic, Indian, Southern (Antarctic), and Arctic Oceans. The word "sea" is often used interchangeably with "ocean" in American English but, strictly speaking, a sea is a body of saline water (generally a division of the world ocean) partly or fully enclosed by land., The Puerto Rico Trench is located on the boundary between the Caribbean Sea and the Atlantic Ocean. The oceanic trench is associated with a complex transition between the Lesser Antilles subduction zone to the south and the major transform fault zone or plate boundary, which extends west between Cuba and Hispaniola through the Cayman Trench to the coast of Central America. The trench is long and has a maximum depth of or 5.373 miles at Milwaukee Deep, which is the deepest point in the Atlantic Ocean and the deepest point not in the Pacific Ocean., Subject: milwaukee deep, Relation: instance_of, Options: (A) animal (B) area (C) chemical (D) city (E) coat (F) common name (G) continent (H) country (I) curve (J) definition (K) direction (L) fault (M) formula (N) geological process (O) guatemala (P) gulf (Q) human (R) hydrogen (S) island (T) liquid (U) material (V) molecule (W) name (X) ocean (Y) oceanic trench (Z) part ([) plane (\) planet (]) population (^) port (_) process (') quantity (a) republic (b) scale (c) sea (d) series (e) shape (f) single (g) standard (h) state (i) strike (j) surface (k) ten (l) three (m) transform fault (n) two (o) vapor (p) water (q) word (r) year
