D. It provides a general picture of the earth. 2. Why is the seafloor beneath U. S.waters mentioned in paragraph 3? A. To stress the further task of mapping the seafloor. B. To explain the standards of mapping the seafloor. C. To illustrate the geographical features of the seafloor. ...
Part of the energy of these powerful calls travels beneath the ground and bounces(反弹) off the Earth's surface. Some equipment at the bottom of the ocean off the coast of Oregon caught the seismic waves of these fin whale calls. Researchers Kun a and John Nabelek,from Oregon State ...
[04:48.77]The study suggests enough water exists below the surface to form a planet-wide ocean about 1 to 2 kilometers deep. [05:01.00]There is currently no way to confirm the study's suggested existence of liquid ...
It must therefore be true that scientists know less about the ocean floor environment than about almost any other environment on Earth. Which of the following, if true, provides the most support for the conclusion A.Many mountain ranges lie entirely beneath the ocean surface, yet new underwater...
Our oceans are a marvel – alive with color, noise, drama, curious life forms, and fascinating creatures – and that is just what we know about today! Every day, scientists learn more about the wonders beneath the waves.From space, our planet Earth shines blue amidst the infinite blackness...
The ocean bottom a region nearly 2.5 times greater than the total land area of the Earth is even today largely unexplored.Until about a century ago the deep-ocean floor was completely inaccessible and hidden beneath waters averaging o
How does this property affect large bodies of liquid water on Earth? What is groundwater? a. All liquid water that resides beneath the Earth's surface b. Muddy mixtures of water and dirt that lies beneath the Earth's surface c. Only the water found in underground lakes and rive...
So much of the world’s oceans have yet to be explored beyond a certain depth, so it is likely that many other animals lurk beneath the surface. The Most Dangerous Ocean Animals The stomach of a pufferfish can inflate up to three times its normal size. Its deadly toxins can be ...
The water is likely contained in a deep layer of iguanas rock beneath the Martian surface. Scientists said that the water likely moved down from the surface billions of years ago, when water is believed to have flowed freely on Mars.There is currently no way to confirm the study's ...
3. Bottom water extends beneath the Atlantic layer to the ocean floor. This is colder than the Atlantic water (below 32 °F, or 0 °C) but has the same salinity. 4. An inflow of Pacific water can be observed in the Amerasia Basin but not in the Eurasia Basin. This warmer and fresh...
