From this restoration it appears that the depth to the top of Layer 3 at the time it was formed is 4.25 (卤 1.25) km below sea level regardless of whole crustal thickness or spreading rate. These results suggest that the mechanism of construction of oceanic crust is, in many ways, ...
Which layer is more likely to have a greater thickness difference between the continental and oceanic regions? A. The outer core. B. The inner core. C. The crust. D. The mantle. 相关知识点: 试题来源: 解析 C。解析:地壳在大陆和海洋区域之间更有可能有较大的厚度差异。大洋地壳较薄,大陆...
All models of the magmatic and plate tectonic processes that create continental crust predict the presence of a mafic lower crust. Earlier proposed crustal doubling in Tibet and the Himalayas by underthrusting of the Indian plate requires the presence of
Where is the Earth's crust the thinnest? Which layer of the Earth contains magma? Which layer of the Earth are the lithosphere and asthenosphere found? In what layer of the Earth's interior do primary waves travel the fastest? What is the thickness of the Earth's inner core?

(yellow-shaded rectangle in Fig.3c). As a consequence, the estimate of LSL thickness improves to 150 ± 15 km (1σ, red contours in Fig.2c), while core density and radius are slightly modified to 6.65 ± 0.1 g cm−3and 1675 ± 30 km (1σ, red ...
What is thickness in meteorology? What is responsible for the weather patterns in the troposphere? What are the layers of the Earth's ecosphere? What is saturated air in meteorology? What is convection in meteorology? What layer of the atmosphere are cirrus clouds in?
from the axis is due to successive episodes of volcanic activity increasing the thickness of the uppermost crustal section from the top, rather than tectonic fracturing lowering the uppermost crustal seismic velocities and pushing the bottom of layer 2A downwards as the crust moves away from the ...
