Density, because the core is made of metals like iron and nickel
I believe it is called elastic deformation. Have a great day ! :)
Th correct answer is letter A. Echo sounding is very useful for depth profiles where SONAR is used to determine the depth of water through the transmission of sound pulses. It is calculated by checking the interval between the mission and the pulse that is recorded within the SONAR device.
Answer:
A. True
Explanation:
Oceanic crust, while older than plateaus of rocks found far away from volcanic activity, it is much thinner, denser, younger, and of different chemical composition than continental crust. Continental crust is typically 30-50 km thick, whilst oceanic crust is only 5-10 km thick. On the other hand, plateaus of rocks are formed from volcanic activities and are of more recent occurrence than oceanic crust.
