These lines are artifacts of the ocean floor mapping process. Oceanographers use sonar—sound waves—to map the ocean bottom. These sonar readings are typically taken by ships towing submersible devices that send out sound waves.
What's at the bottom of the ocean floor?
The main features are mid-oceanic ridges, hydrothermal vents, mud volcanoes, seamounts, canyons and cold seeps. …
Why does Google Maps block the ocean?
You can always use Google Earth if you want to see the surface of the ocean or the 3D modelling of the sea floor. But since Google has to buy their satellite imagery from those with the satellites, it would be wasteful to spend money on areas that have no land, only featureless surface of the ocean.
What are the lines on Google Earth?
Borders, or boundaries, are shown in different ways in the new Google Earth. The lines are drawn based on the status of the border.What are the blue lines in the water on Google Maps?
The blue dashed lines on oceans or creeks indicate shipping lanes. That becomes useful to know whether there is any ferry service between two ports or points of interests.
Does the sea have a bottom?
The seabed (also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean. All floors of the ocean are known as ‘seabeds’. The structure of the seabed of the global ocean is governed by plate tectonics. Most of the ocean is very deep, where the seabed is known as the abyssal plain.
Is the bottom of the ocean sand?
there is NO SAND in the bottom of the ocean. Sand, crushed up rock, ground up silica is made be grinding rocks together. Think glaciers 1+miles deep pressing down on giant landforms and moving along the surface at 1 mile every 10 years for 3 million or more years; that is a sand machine.
What are the bumps in the ocean on Google Earth?
Those bumps at the surface of the ocean, Sandwell says, reflect features—such as seamounts or extinct volcanoes—on the sea floor below. “A seamount, for example, exerts a gravitational pull, and warps the sea surface outward,” he says. “So we can map the bottom of the ocean indirectly, using sea-surface topography.”Where is the lost city of Atlantis on Google Earth?
A video posted on YouTube claims that Google Earth has discovered proof that Atlantis existed. The footage shows a strange structure at the bottom of the ocean floor that does not appear to be natural. The formation lies at a depth of over 4500 meters under the ocean off the coast of Africa.
Does Google Earth show the ocean floor?The ocean floors contain dramatic landscapes – volcanic ridges, lofty peaks, wide plains and deep valleys. Thanks to a new synthesis of seafloor topography released through Google Earth, armchair explorers can now view five percent of the deep ocean floor in far greater detail than ever before.
Article first time published onWhy is Google Maps blurry in Korea?
The satellite imagery you see in South Korea is actual satellite imagery. That is the resolution of non-military satellite images. The reason it looks blurry to you is that you are accustomed to seeing aerial photos. South Korea does not allow exporting aerial photos and therefore, Google Maps can’t buy them.
Why are some places blurred on Google Earth?
According to Google, some fuzzy places, particularly in remote regions, are simply the result of a lack of good aerial images. When better imagery becomes available, Google incorporates it, so “censored” spots may become clear with the next software update.

What does the GREY line mean on Google Maps timeline?
“The grey line indicates that Google Maps does not have enough information about what transport method was being used between those times. It could be due to movement, or the device being turned off and on again, or just poor signal on the wifi/4g/gps connections it was using to determine the location.”
What is the line in the ocean?
The Pacific White Line is a periodic but random natural feature in the Pacific Ocean. It is a huge collection of fish, foam and algae that usually occurs between January and August. When conditions are right it can be seen from space.
Why are the Nazca lines blurred on Google Maps?
The Nazca Lines can only be discerned from high elevation or altitude. The ancients used these ways to attract future generations to search for the wisdom deposited there. Our experts are slow to learn, they called the Ica Stones fake, and missed the climate change. These messages were probably left by the Lemurians.
Is sand really fish poop?
The famous white-sand beaches of Hawaii, for example, actually come from the poop of parrotfish. The fish bite and scrape algae off of rocks and dead corals with their parrot-like beaks, grind up the inedible calcium-carbonate reef material (made mostly of coral skeletons) in their guts, and then excrete it as sand.
What is under beach sand?
Often, underneath the loose sand of a beach is a layer of hard, compacted sand, which could be on its way to becoming sandstone if the necessary cement, pressure and heat ever appear — and if is not eroded by severe storms. … These beaches commonly lose all the new sand in five years or so.
Is the ocean floor flat?
The oceans’ floors are not a flat, sandy expanse – they are every bit as varied as the landscapes above water, with plunging valleys and huge mountains.
What happens to a human body at the bottom of the ocean?
The pressure from the water would push in on the person’s body, causing any space that’s filled with air to collapse. (The air would be compressed.) So, the lungs would collapse. … The nitrogen would bind to the parts of the body that need to use oxygen, and the person would literally suffocate from the inside out.
How deep does the ocean go down?
The average depth of the ocean is about 12,100 feet . The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam.
Who ruled Atlantis?
Its culture was advanced and it had a constitution suspiciously similar to the one outlined in Plato’s “Republic.” It was protected by the god Poseidon, who made his son Atlas king and namesake of the island and the ocean that surrounded it.
Was Atlantis a real city?
Atlantis didn’t exist at all—Plato invented it. Most historians and scientists throughout history have come to the conclusion that Plato’s account of the lost kingdom of Atlantis was fictional.
Where is Atlantis underwater?
It was situated in the Atlantic Ocean, somewhere outward from the Strait of Gibraltar. It’s a landmass large enough that, if it really existed somewhere underwater in the Atlantic, it would certainly appear on sonar maps of the ocean floor.
Why does the sea look weird on Google Earth?
Google Earth shows the seafloor topography. That rough looking surface is quite real. It is based on sonar reflection bathymetry, with lots and lots of cable sonde measurements of depth as control points.
How do we know what the ocean floor looks like?
But satellites can use radar to measure the height of the sea’s surface very accurately. And if there are enough measurements to subtract the effects of waves and tides, satellites can actually measure bumps and dips in the sea surface that result from the underlying landscape of the ocean floor.
How deep is the the Mariana Trench?
It is 11,034 meters (36,201 feet) deep, which is almost 7 miles. Tell students that if you placed Mount Everest at the bottom of the Mariana Trench, the peak would still be 2,133 meters (7,000 feet) below sea level. Show students NOAA’s Mariana Trench animation.
Where is the ocean the shallowest?
The Arctic Ocean is the shallowest (mean depth 1361 m) and has significantly larger continental shelves than other oceans.

Why does South Korea smell bad?
Experts say hydrogen sulfide, an odor-causing gas that results naturally from septic conditions during the collection and treatment of wastewater, is only slightly soluble and therefore easily released into the atmosphere. “This summer has been especially brutal,” said Kim So-hye, a mother of two in western Seoul.
Can you see North Korea on Google Earth?
North Korea was long a big blank space on Google Maps. No roads were visible. … Google changed that on Tuesday, unveiling a detailed view of North Korea that points out spots as small as stores or subway stops, and as large as North Korea’s gulags, some of which are the size of cities.
