The Dead Sea and the Great Salt Lake are like in what way?
Both the Dead Sea and the Great Salt Lake are hypersaline bodies of water with high salt concentrations, which makes them too salty for most organisms to survive. Additionally, both are popular tourist destinations known for their unique natural beauty and therapeutic properties.
Suppose the paramecium were placed in a container of sea water what would you observe?
If placed in sea water, the paramecium would likely experience a change in its environment due to the difference in salt concentration compared to its usual freshwater habitat. This could lead to osmotic stress on the paramecium, affecting its ability to regulate water and ions. In such conditions, the paramecium may exhibit behaviors such as swimming irregularities or changes in cell volume as it adapts to the new osmotic conditions.
Are there fish in the dead sea?
yes. it is only called the dead se because the waters are so calm. this is caused because of the extreme amount of salt in its waters. bacteria and different types of plankton makeup the majority of life in the dead sea though.
What would happen if salt water is heated?
Eventually if heated long enough (and hot enough) all the water would either eat the world or MELT (turning into steam), leaving behind nothing but solid salt behind. This is one way that you can remove salt from sea water in fact.
How many people visit the dead sea every year?
Around 1 million people visit the Dead Sea every year. It is a popular tourist destination known for its unique qualities and health benefits.
What Were The 5 Biggest Archaeological Discoveries Of The Last Decade?
Can you believe it’s been nine years since the last Indiana Jones film came out? As much as we might wish to forget Shia LaBeouf swinging from vines amidst a family of monkeys, the reality is that Harrison Ford’s scruffy-faced adventurer made archaeology cool for generations of young boys and girls. Now, a similarly exciting first look at the rebooted Tomb Raider franchise proves Alicia Vikander’s Lara Croft is set to become Jones’ worthy successor.

But while the actual practice of excavating and restoring ancient artifacts may not be full of deranged Nazis and supernatural curses, for Dr. Deborah Gangloff, president and CEO of the Crow Canyon Archaeological Center in southwestern Colorado, as well as vice president for outreach and education at the Archaeological Institute of America, it’s always been exciting.
Looking toward the future, not just the pastGangloff is a New World archaeologist, which means her expertise is primarily in North America. For Gangloff, archaeology is not just about digging up the past, but looking toward the future.

“There are many reasons why archaeology is relevant today, and we need to do a better job of communicating those reasons to the public and decision makers,” she says. “Archaeological findings can give politicians, planners, and the general public a significant, deep-time perspective on key issues (changing environments, economic and demographic trends, etc.) and quite possibly point the way towards solutions for the future.”

Since we last saw Indiana Jones raiding the Crystal Skull onscreen, there have been many exciting archaeological discoveries in the real world. Each one has pushed the field forward and taught us something about the past we didn’t know before. With that in mind, here are five of the most important discoveries made in the last decade:
1. The Lovers of ValdaroWe’ve heard of “’Til death do us part,” but a 2007 discovery near Mantua, Italy, takes that concept to an entirely new level. Two skeletons from over 6,000 years ago were excavated, discovered in an embrace. Their legs were intertwined and their arms were wrapped around one another. Immediately, speculation about who these two people were and how they could have died ran rampant. It didn’t help that Mantua was where Shakespeare’s Romeo was exiled after killing Tybalt and where he learned of his darling Juliet’s death.
Scholars are still divided on what may have happened to the lovers. Tests have concluded that the skeletons are definitely a woman and a man, between 18 and 20 years old. But, were they killed? Did they die holding each other on a frozen Italian night? Or were they placed in their intriguing position after their deaths? The world may never know, but it’s fun to speculate.
2. The Nesting Pyramids of Chichén ItzáEven if you’ve never been to Chichén Itzá on Mexico’s Yucatán peninsula, chances are you’ve seen the iconic El Castillo pyramid in photos. Constructed between 950 and 1000 A.D., the ancient Mayan structure rises 100 feet into the sky and is 180 feet wide at its base. On each side, a set of 91 steps rise to the top. When added together with the one it takes to enter the structure, the total number of steps comes to 365—one calendar year.

What you might not know, however, is that El Castillo actually has two other pyramids inside it. The first has been known for awhile; it was discovered in the 1930s and is believed to have been built sometime between 850-900 A.D. But as recently as November 2016, scientists were still making discoveries at the site.
Archaeologists used electrical resistivity to find a third, even smaller pyramid hidden within the first two. This one was constructed sometime between 600 and 800 A.D. As the oldest of the three, this third structure is thought to be more purely Mayan. Archaeologists believe it can reveal a lot about the beginnings of the settlement, as well as the Mayan’s earliest cultural influences.

This recent discovery will surely increase tourism to the Yucatán peninsula, which Gangloff says is a big benefit of the field. “[Archaeology]…helps increase visitation to cultural and historic sites that brings more people to tour archaeological sites, and that makes them more knowledgeable about what we do and helps support local economies through tourism,” she says.
3. The Youngest Known MummyIn the Fitzwilliam Museum in Cambridge, England, sits a small cedar coffin that was unearthed in 1907. The coffin dates back almost 2,500 years, from the Egyptian Late Period, between 664 and 525 B.C. Until last year, museum curators believed the coffin was too small to hold anything but the mummified organs of a deceased individual.

That is, until a micro CT scan showed a much more interesting find: a mummified fetus, believed to be only 16-18 weeks old when it died from a probable miscarriage. This makes the fetus the youngest mummy ever found. The scan shows two hands with five fingers each, and the fetus’ arms are crossed over its chest. This remarkable find proves what recent advances in technology enables archaeologists to do.
In a press release, Dr. Tom Turmezei, who collaborated with the museum on the find, said, “CT imaging has been used successfully by the museum for several projects in recent years, but this is our most successful find so far. The ability of CT to show the inner workings of such artefacts without causing any structural damage proved even more invaluable in this case, allowing us to review the foetus for abnormalities and attempt to age it as accurately as possible.”

Julie Dawson, head of conservation at the Fitzwilliam Museum, added in a statement: “This ground-breaking find educates us further still in our conception of just how precious the unborn child was in Ancient Egyptian society. The care taken in the preparation of this burial clearly demonstrates the value placed on life even in the first weeks of its inception.”
4. New Dead Sea ScrollsIt was the archaeological find of the century. Between 1946 and 1956, 11 caverns in the Qumran caves near the Dead Sea in Israel and Palestine yielded thousands of fragments of historically significant parchment paper stored in ancient, earthen jars. In early 2017, researchers found a twelfth cave.
For more what they uncovered, and what it means to history, watch our video below.
5. Greece’s Largest TombThe Hill of Kasta was almost discovered first in the 1970s, when an archaeologist speculated that the site, near the ancient Greek city of Amphipolis, hid a large tomb under the earth. His work took him elsewhere, and archaeologists were unable to revisit the site until four decades later. As expected, the tomb was waiting for them.
The tomb, the largest of its kind in Greece, dates from the 4th century B.C., is guarded by two large marble sphinxes, and contains three separate chambers.
What’s more, archaeologists discovered the skeletons of five people: a woman over 60 years old, two males between 35 and 45, a newborn, and a third male whose age is difficult to determine. Initial reports that it was the tomb of Alexander the Great were later dismissed.
More likely, the tomb belonged to a member of an ancient royal family or a wealthy citizen. Inscriptions within the tomb apparently link the tomb to that of Hephaestion, a nobleman and a general in Alexander’s army.
The Accumulation of ResearchSo does Gangloff have a find she’s been a part of that excites her most? For her, it’s not about any one discovery, but the sum total of research that provides insight into the past.
“It’s not the individual artifacts we find that are the most interesting, it’s the accumulation of research findings that help give us a more complete picture of a society of the past,” she says. “For instance, in the southwest of the US, we now have a better view of how people lived 700 years ago and when and why this area of the Four Corners was nearly totally abandoned in the late 13th century.”
To the layperson, that may sound less interesting than cracking bullwhips and fighting off villains, but Gangloff doesn’t mind the way her field is portrayed in the media. In, fact, she says, it can do some good: “While I can’t speak for the entire profession, the popular cultural interpretations of archaeology and archaeologists, while they amuse professionals with their sensationalism, do result in an up-tick in interest in archaeology and in enrollment in college courses.”
So I guess Shia LaBeouf’s monkey swing isn’t all bad.

~1/2 pound
First, note that 1 gram was originally defined to be the weight of one milliliter of ice water, so it is a good approximation of water weight (and mass).
Second we need milliliters of water in a cup:
There are 8 fluid ounces in a cup (that's *fluid* ounces, a measure of volume, not ounces, a measure of weight)
1 US fluid ounces = 29.5735296 milliliters x 8 fl. oz / cup= 236.588237 milliliters in a cup
By the above approximation, 1 cup, therefore, weighs 236.6 grams
236.6 grams = 0.521613712 pounds which equals approximately 1/2 pound.
The Dead Sea is called the Dead Sea because no living creature can live in it (other than
humans)
It is also so named because there is no water that flows out of it...
The Red Sea and the Dead Sea are two separate bodies of water.
The Red Sea separates Africa from Asia. It is a large inlet of the Indian ocean.
The Dead Sea is a large saltwater lake bordering Israel, Jordan and the West Bank. It is made after the river Jordan flows from the Sea of Gallilae down the river and lands there. It gets it's name The Dead Sea because it is so salty nothing can live in it.
Is the dead sea salty or less salty?
The dead sea is getting more salty. Like all seas, rivers which carry bits of sedimentary rock, enter the sea and "dump" whatever they carried on its journey to the sea. As you may well know, there is salt in this sedimnetary rock. The dead sea is more salty that others for a fews reasons: * Higher salt content in rocks & soil * More rivers entering sea
Why do ships float higher on sea water than in fresh water?
Because the the sea water contains salt, which increases the density of the water. Therefore, the ships becomes even less dense than the water, making it float higher.
What is the absolute location of the dead sea?
Dead sea is a salt lake which is located in middle east. It borders Jordan to the east and Palestine and Israel to the west. It is 9-6 times more saline than ocean hence no marine life can flourish in it. That is why it is called dead sea.
How does the amount of salt in the dead sea compare to ocean water?
The salinity in isolated seas and salt-water lakes (for example, the Dead Sea) can be considerably greater. SO there's a high salinity in the Dead Sea. :D
What is the volume of the dead sea?
There are roughly about 9,000,000,000,000,000,000,000,000,000 cubic gallons of water in the dead sea. But the dead sea is very slowly shrinking so in 100 years time there will only be 9,000,000,000 cubic gallons of water in the sea!
Why cant you dive into the Dead Sea?
Diving or going under the surface of the water in the dead sea is very difficult due to the high salt concentration, makes the water more dense, allowing objects to float more easily. If you find a place high enough to jump from, you can still dive, but its fairly shallow and the bottom is covered with sharp crystallized salt that will probably hurt you, and there is a pretty thick layer of mineral oil in the Dead Sea that will coat your entire body and make you extremely uncomfortable if you get you face wet.
How would you describe the dead sea?
The Dead Sea is called the Dead Sea because nothing can live in it. This is due to the massive amounts of salt. It has ten times more than the ocean. The sea is the lowest elevation on earth. It is 420 meters under sea level.
