The world’s oceans are truly amazing. roughly seventy-one percent of the earth is covered by oceans, and they are the home to countless fish, crustaceans, and other marine animals. the five major oceans—the arctic, the atlantic, the indian, the pacific, and the southern, which are then broken down into smaller seas—provide food for humans and animals, entice explorers, enable trade, and affect the climate and environment the world over. 2with all of the creatures that call the ocean home, the waters provide an abundance of food for both humans and animals. for this reason, civilizations have arisen along coastlines around the world for millions of years. settling along the ocean eventually enabled people to trade, and the location even influenced their cultures, which is evident in many ancient mythologies. 3ocean exploration has occurred for ages and has opened up new worlds to those daring enough to set sail. explorers from european nations such as great britain, spain, portugal, and also the vikings from scandinavia, are likely to be the most well known, but every nation with a coastline has had its share of oceangoing explorers. these explorers found new lands where people very often led lives rather different from their own. many people can trace their roots back to these early settlers and explorers, who founded the colonies that became the famous seaside cities we know today. 4by interacting with and trading with newfound nations, explorers were able to bring back products that were exotic to their own shores. they opened up trading routes between different countries. trade has been an important part of life for most cultures throughout history; it is even more so today, as the internet has improved our ability to maintain a global market. today, most of the world’s goods are transported on the oceans from one seaport to another before making their way to your home. 5climate and weather are also intricately connected to the world’s oceans. impressive storms form over the oceans and at times come ashore. the currents that flow throughout the ocean bring warm air to some coastal regions and cold air to others. along with warm or cold air, precipitation is also carried to different coastal areas. once in a specific coastal area, wind can carry the warmer or cooler air and also the precipitation further inland to affect the climates there as well. 6between the majestic and useful marine animals, the chance of exciting new places to explore, the usefulness of trade, and the amazing effects on the climate, the oceans are among the most interesting areas of study. what is the main purpose of the author of this passage is: a) to persuade readers to schedule a vacation soon to spend time at the beach. b) to describe in detail a few of the world's best know oceans and its inhabitants. c) to convince readers that the oceans of the world are in severe danger of pollution. d) to describe some of the wonders of the oceans that make it such a precious resource. the author uses paragraph 6 to: a) urge his readers to take action b) readers understand his point about how oceans affect weather c) describe to readers how the oceans humans and animals survive. d) provide readers with his conclusion about why oceans are interesting. in paragraph 4, what point is the author making when he talks about the internet: a) the internet provides us with facts about people who first settled along oceans around the world. b) the internet allows us to buy products from and sell products to people around the world. c) the internet lets us look up information about different countries all over the world. d) the internet makes it possible to ship products to locations all over the world.

Monsters of the deep the ocean is full of mysteries and amazing creatures. since the first sailors left their home shores and set off for adventure, stories have been told of the strange and wondrous beasts encountered on the open ocean. with only glimpses and imagination-enhanced stories to go on, humans have made many an interesting creature into a monster. the truth is, the ocean's scariest creatures inhabit such extreme depths that humans are rarely, if ever, threatened by them. that does not mean they are not the stuff of nightmares. consider, if you will, the following frightful fiends. atlantic hagfish part eel, part sea snake, this sea serpent may have inspired many stories. lacking the scales that most fish have, the hagfish secretes the most amazing slime to protect itself. this slime may be used to suffocate predators. the slime includes small fibers that make it almost impossible to remove. but the hagfish's truly horrific nature lies in what it does to its prey, not its predators. with an excellent sense of smell that compensates for almost total blindness, the hagfish will locate and latch on to a victim. with a circle of razor sharp teeth, the hagfish bores a hole into the side of its now-doomed prey. once the hole is complete, the hagfish just welcomes itself inside for a meal of fish innards. it essentially eats its prey from the inside out. like other deep-sea monsters, however, hagfish are seldom a nuisance to humans. they live most of their lives at depths of up to 5,600 feet. in fact, they prefer a soft sea bottom so they can quickly bury themselves to hide from threats. gulper eel another, more hideous, fiend of the deep is the gulper eel. this creepy critter is part eel and part giant pouch. like a pelican's enormous pouch-shaped mouth, the mouth of the gulper eel can open quite wide to gulp prey. it has a long tail tipped with a glowing organ that is used to lure in prey. in part to its tail, the gulper can reach up to six feet in length. because its tail is so thin, it is not able to pursue prey with any speed, but it can scoop up hundreds of small crustaceans or shrimp in one bite. often swimming through these prey groups with its mouth wide open, its large jaws allow it to feed on squid and other creatures much larger than itself. gulper eels have only been studied because they sometimes get caught in the nets of fishermen. the depths they inhabit make it quite difficult for scientists to study them. they can go as deep as 6,000 feet, well beyond the abilities of humans to pursue them. vampire squid perhaps the most frightening of the deep-sea monsters is also the smallest. the vampire squid reaches lengths of only six inches. it is also one of the most ancient of the deep-sea monsters. scientists believe it to be the last surviving member of its order. to see the vampire squid is to wonder how many kinds of sea creatures have been mashed into this one odd-looking spook. part squid, part octopus, and part fish, the vampire squid has features of all of these. first, it has large fins at the top of its head that look like ears. flapping like dumbo, the squid uses these fins to get around. it also has tentacles and a large bulbous head like an octopus. its arms, however, are connected by webbing that allows it to form a cloak around itself when frightened. like the octopus, it can change its colors, even making its cloak so dark that it appears invisible. remarkably, it has the largest eyes compared to its body size of any creature on earth. despite its mere six-inch length, its eyes are as big as those of a large dog. with its glowing orbs of eyes and its disappearing tricks, it's no wonder it's named after one of the most feared creatures of legends and folklore: the vampire. these creatures make one wonder not just about the odd members of the deep-sea community, but also what mysterious things inhabit the regions never visited by humans. what may be lurking in the deepest, darkest corners of the deep blue seas? one thing we know for certain, much like the outrageous monsters we conjure in our worst nightmares, the deep ocean is an equally imaginative source of shock, awe, and outright fright. what are the key differences between the atlantic hagfish and the gulper eel? use details and quotations from the text to support your answer.
