Ocean Rivers Salty

shared by morales5853 on 03 Dec 14 - No Cached
  • In the beginning, the primeval seas were probably only slightly salty. But over time, as rain fell to the Earth and ran over the land, breaking up rocks and transporting their minerals to the ocean, the ocean has become saltier.
  • Rain replenishes freshwater in rivers and streams, so they don’t taste salty. However, the water in the ocean collects all of the salt and minerals from all of the rivers that flow into i
  • It is estimated that the rivers and streams flowing from the United States alone discharge 225 million tons of dissolved solids and 513 million tons of suspended sediment annually to the ocean. Throughout the world, rivers carry an estimated four billion tons of dissolved salts to the ocean annually.

  • About the same tonnage of salt from ocean water probably is deposited as sediment on the ocean bottom and thus, yearly gains may offset yearly losses. In other words, the ocean today probably has a balanced salt input and output (and so the ocean is no longer getting saltier).

      the sea is salty because it brings the earth materials and it becomes salty. The rivers are not salty because when it rains it takes away everything and the earth matirals don't go to the rivers.

  • wice being turned back by ice, Hudson embarked on a third voyage–this time on behalf of the Dutch East India Company–in 1609. This time, he chose to continue east by a more southern route, drawn by reports of a possible channel across the North American continent to the Pacific. After navigating the Atlantic coast, Hudson’s ships sailed up a great river (which would later bear his name) but turned back when they determined it was not the channel they sought. On a fourth and final voyage, undertaken for England in 1610-11, Hudson spent months drifting through the vast Hudson Bay and eventually fell victim to a mutiny by his crew. Hudson’s discoveries laid the groundwork for Dutch colonization of the Hudson River region, as well as English land claims in Canada.

      the water of the world ist goes in a contninouse cycle first evaporated and then it rain.
  • Water falls all over the planet, but when it passes through soil and rocks it slowly dissolves bits of minerals, including sodium chloride (salt). This means rivers and lakes have tiny fragments of salt in them, which — little by little — are carried into the sea.

      the rain falls to the grownd between rocks and pants. that rain becomes into river and the earth becomes salty. Like there are vocanos under water the volcanos have minerals and the sea keeps them.
  • Rivers and lakes are replenished with fresh rainwater, but oceans are a sort of dumping ground where water with accumulated salt keeps adding to the salinity. There are also vents and volcanoes under the ocean that increase the amount of minerals, especially salt.

  • d. He had brothers, Thorvald and Thorstein, and a half-sister, Freydis. In the year 999 BCE, Ericsson sailed to Norway to visit King Olaf Trygvson. On his way the ship was blown off course and he landed on one of the Hebrides islands. Continuing poor weather made it impossible for him to leave so he spent the summer on the island.
  • . She gave birth to his son and as his departure date drew near, she asked that he take her with him. He refused, citing her family connections. Thorgunna had a reputation for being able to predict the future, and vowed that even though Leif was leaving them, one day she and their son would journey to find him and the experience would not be a good one.

  • What is known for certain is that Leif and the boy eventually found each other and the young man was recognized as his son.
  • Nevertheless, Leif left the island and got to Norway by the fall. King Olaf welcomed him to his court and asked if Leif had plans for a voyage to Greenland. The king had recently been converted to Christianity and wanted Leif to proclaim Christianity to the Norse settlers living in Greenland, including his parents. He returned to Greenland, and as the king wished, spread the message of Christianity. Leif’s mother, Thjodhild, quickly adopted the new religion, but his father, Eric, was reluctant to give up his pagan beliefs. Only when Thjodhild refused to live with
  • him as man and wife, did Eric the Red finally convert to Christianity.
  • Leif Eiriksson’s exploration and discovery of America was inspired by the accidental voyage of Bjarni Herjulfson.
  • As a skilled sailor and trader, Herjulfson had devoted himself to going on trading voyages from Iceland every other year
  • In 1002 BCE, Leif Eiriksson decided to explore the unknown lands discovered by Herjulfson while on the quest for his father.
  • Leif bought a ship from Bjarni and gathered a crew of thirty-five men.
  • Eric, his father, was approached about being the expedition leader. A fall from a horse prior to embarking convinced Eric that he would be unlucky on the voyage and that he was too old to set off on another adventure. Leif himself took command and the ship and crew departed.
  • The first country Leif encountered was the last one Herjulfson had seen. It was barren, with glacier-topped mountains and vast stretches of rock-covered ground
  • Initiating the practice of naming the lands he found after their geological and physical traits, he called this area Helluland, or “land of flat rocks.” (Labrador)
  • The second country Leif sailed to was level and wooded, with deep white beaches and a sloping shoreline. He called this place Markland (Newfoundland) or “forest land.” Leaving there, he sailed northeast. He found an island north of the mainland. He and his crew sailed the channel between the island and mainland and steered west. When they found land they went ashore, discovering a small river that flowed to the sea. They returned, took the ship up the river to a lake where they decided to build houses, and stayed through the winter.
  • The area had salmon in the river and lake; the winter was mild and almost frost-free, and the grass did not wither during the cold season.
  • The hours of daylight and nighttime were more equally divided than in either Iceland or Greenland
  • Leif divided his crew in half, determined to explore the area. Half would stay in camp while the other half went as a group to investigate the surroundings. The exploration crew was to go no further than the distance they could travel in order to return to camp by nightfall.

  • As water flows in rivers, it picks up small amounts of mineral salts from the rocks and soil of the river beds.
  • but the salt remains dissolved in the ocean - it does not evaporate. So the remaining water gets saltier and saltier as time passes.
  • This very-slightly salty water flows into the oceans and seas. The water in the oceans only leaves by evaporating (and the freezing of polar ice),

Salty ocean

shared by marino5856 on 04 Dec 14 - No Cached
  • The ocean is salty for several reasons, one of which is the groundwater from rain which trickles down into the ocean and picks up salt from the earth along its way! But this same water trickles down into lakes… so why aren't lakes salty?
  • The reason lake water usually isn't salty (or at least it's less salty than ocean water) is because the salty groundwater not only runs into the lakes, but also back out of it! Unlike the huge, vast ocean which already covers most of the Earth and therefore can't open up to any larger body of water, most lakes have outlets from which water leaves. This means that the salty groundwater has a chance to filter out and escape! (In the ocean, it has nowhere e
  • lse to go!)
