![]() ![]() Tsunami are UNDETECTABLE by ships in the open ocean. Tsunami HAVE a very long wavelength, so they travel at very high speeds (equivalent to the speed of a jet airplane). it is NOT AVAILABLE on demand, and there currently is no viable way to store the energy Of the following statements about tsunami, which is/are true? -THE tsunami warning system uses seismic waves and deep-ocean pressure sensors to detect tsunami. A disadvantage shared by wave, solar and wind energy is that _. MAGMA is not generated in significant amounts until the subducted plate has reached a depth of 100 Volcanic Arc Creation. What might be a possible explanation for the fact that the there are no volcanoes over areas where the subducted plate is less than 100 kilometer deep? There are no volcanoes over plate that is less than 100 kilometer deep. The volcanoes appear to line up along the (100-kilometer dashed) depth isoline, and there are more over areas where the plate is deeper. ![]() Describe the relationship between the location of volcanoes on the island of Japan and the depth to the subducted plate below Japan. What is the magnitude of the maximum slip indicated here, in meters? 24 According to this chart, in what general direction did slip occur? The motion was both UPWARD and toward the EAST. The effective height of the tsunami would have been increased by the amount of subsidence of the coastline: here, around 1 meter. Scientists first saw this natural landmark in orbiter images years before the rover even launched into space.In light of your answers to Parts A through B, explain how the earthquake changed the coastline in a way that increased the destructiveness of the tsunami as it came ashore. The robot found the rippled rocks about a half-mile up the mountain on a feature dubbed " Marker Band (Opens in a new tab)," a dark, thin layer of rock sandwiched between lighter layers. Creeping through the desolate alien wilderness, Curiosity is exploring an environment that could have been hospitable to tiny microorganisms, if any ever inhabited Mars. The rover has slowly climbed the slope of Mount Sharp, a three-mile-high mountain once ribboned with streams, since 2014. Want more science and tech news delivered straight to your inbox?

(opens in a new tab) (Opens in a new tab) The spacing between ripples, for example, is an indicator of the water's depth and the size of the waves that molded them. ![]() Still, geologists can learn a lot from these rocks with water imprints, which can also be found on Earth in petrified seabeds from eons ago. By exploring former water sites, NASA hopes to find evidence of ancient microbial life. Lakes and oceans could have been a key ingredient for supporting primitive Martian life, once upon a time, but this doesn't outright mean the environment was habitable. The obsessive search for past water on Mars, a frozen desert, is a quest to prove the Red Planet was once wet, warm, and more Earth-like. In the first year (Opens in a new tab) of Curiosity's expedition, it sent home pictures of a stream bed, eroded and dry, with bountiful round pebbles, similar to those formed on Earth from flowing water. Martian water chiseled sinuous river beds and deep ravines into the ground, now hollowed out and dusty. "We climbed through thousands of feet of lake deposits and never saw evidence like this."įor years researchers have found signs that Mars used to be bathed in creeks and lakes. "Now we found it in a place we expected to be dry." "We climbed through thousands of feet of lake deposits and never saw evidence like this," said Ashwin Vasavada, Curiosity’s project scientist at NASA’s Jet Propulsion Laboratory, in a statement (Opens in a new tab). The movement on top churned up sediment from the bottom, they suspect, forming the combed texture. Mission scientists say waves of water lapping on the surface of a shallow lake created these grooves, perhaps billions of years ago. The rocks are like the undulating patterns one might find when the tide reels the ocean back from a beach, revealing wobbly tracks on the temporarily exposed sand. ![]() A NASA rover exploring the foothills of a Martian mountain has found rippled rocks, offering scientists the clearest evidence yet of ancient water waves on the Red Planet.Ĭuriosity, a car-size robot that has been rumbling over Mars for a decade, took photos of the peculiar geology in mid-December (Opens in a new tab). ![]()
