Sea

A sea is a large body of salt water that is surrounded in whole or in part by land. More broadly, "the sea" is the interconnected system of Earth's salty, oceanic waters—considered as one global ocean or as several principal oceanic divisions. The sea moderates Earth's climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle. Although the sea has been travelled and explored since prehistory, the modern scientific study of the sea—oceanography—dates broadly to the British Challenger expedition of the 1870s. The sea is conventionally divided into up to five large oceanic sections—including the IHO's four named oceans (the Atlantic, Pacific, Indian, and Arctic) and the Southern Ocean; smaller, second-order sections, such as the Mediterranean, are known as seas.

Owing to the present state of continental drift, the Northern Hemisphere is now fairly equally divided between land and sea (a ratio of about 2:3) but the South is overwhelmingly oceanic (1:4.7).Salinity in the open ocean is generally in a narrow band around 3.5% by mass, although this can vary in more landlocked waters, near the mouths of large rivers, or at great depths. About 85% of the solids in the open sea are sodium chloride. Deep-sea currents are produced by differences in salinity and temperature. Surface currents are formed by the friction of waves produced by the wind and by tides, the changes in local sea level produced by the gravity of the Moon and Sun. The direction of all of these is governed by surface and submarine land masses and by the rotation of the Earth (the Coriolis effect).

Daffy Duck

Daffy Duck is an animated cartoon character produced by Warner Bros. Styled as an anthropomorphic black duck, the character has appeared in cartoon series such as Looney Tunes and Merrie Melodies, where he usually has been depicted as the best friend and occasional arch-rival of Bugs Bunny. Daffy was one of the first of the new "screwball" characters that emerged in the late 1930s to replace traditional everyman characters who were more popular earlier in the decade, such as Mickey Mouse and Popeye. Daffy starred in 133 shorts in the golden age, making him the third-most frequent character in the Looney Tunes/Merrie Melodies cartoons, behind Bugs Bunny's 166 appearances and Porky Pig's 159 appearances.

Daffy was number 14 on TV Guide's list of top 50 best cartoon characters and was featured on one of the issue's four covers as Duck Dodgers with Porky Pig and the Powerpuff Girls (all of which are Time Warner-owned characters).

Origin and history

Daffy first appeared in Porky's Duck Hunt, released on April 17, 1937. The cartoon was directed by Tex Avery and animated by Bob Clampett. Porky's Duck Hunt is a standard hunter/prey pairing for which Leon Schlesinger's studio was famous, but Daffy (barely more than an unnamed bit player in this short) was something new to moviegoers: an assertive, completely unrestrained, combative protagonist. Clampett later recalled:

Bugs Bunny

Bugs Bunny is an animated cartoon character, created by the staff of Leon Schlesinger Productions (later Warner Bros. Cartoons) and voiced originally by the "Man of a Thousand Voices," Mel Blanc. Bugs is best known for his starring roles in the Looney Tunes and Merrie Melodies series of animated short films, produced by Warner Bros. during the golden age of American animation. His popularity during this era led to his becoming an American cultural icon, as well as a corporate mascot of Warner Bros. Entertainment.

Bugs is an anthropomorphic gray hare or rabbit who is famous for his flippant, insouciant personality; a pronounced New York accent; his portrayal as a trickster; and his catch phrase "Eh... What's up, doc?", usually said while chewing a carrot. Though a similar rabbit character began appearing in the Warner Bros. cartoon shorts during the late 1930s, the definitive character of Bugs Bunny is widely credited to have made his debut in director Tex Avery's Oscar-nominated film A Wild Hare (1940).
