Scientists use seismic waves to study the Earth's interior. Which part of the Earth is the outermost layer? A. Mantle B. Core C. Crust D. Atmosphere 相关知识点: 试题来源: 解析 C。解析:地球的最外层是地壳,它是地球固体圈层的最外层。地幔是地壳下面的一层,地核则在更深处,而大气圈不属于...
To do so, scientists relied on seismic waves (elastic waves) — waves generated by earthquakes and explosions that travel through the earth and across its surface to reveal the structure of the interior of the planet. Thousands of earthquakes occur every year, and each one provides a glimpse ...
Scientists study seismic waves to learn about the Earth's interior. When seismic waves change speed suddenly, it often indicates a boundary between different layers. Which layer is beneath the crust? A. Inner core B. Outer core C. Mantle D. None of the above 相关知识点: 试题来源: 解...
aSeismic waves generated in Earth's interior provide images that help us to better understand the pattern of mantle convection that drives plate motions. 在地球的内部引起的地波提供帮助我们更好了解披风对流的样式驾驶板材行动的图象。 [translate] ...
Sentence Correction_To map Earth146;s interior, geologists use a network of seismometers to chart seismic waves that originate in the earth146;s crust and ricochet around its interior, most rapidly traveling through cold, dense regions and slower thr
Geologists often use seismic waves to study the interior structure of the Earth. Which of the following statements about seismic waves is correct? A. 级京技于听织包共制次民组级京技于听织包共制次民组P - waves can only travel through solids.级京技于听织包共制次民组级京技于听织包共制...
Seismic wave, vibration generated by an earthquake, explosion, or similar energetic source and propagated within the Earth or along its surface. Earthquakes generate four principal types of elastic waves; two, known as body waves, travel within the Earth
At distances farther than 130 m from the cliff face, the inversion results reveal an earth model dominated by a vertical velocity structure; however, at closer distances we observe significantly slower S-wave values and isolated strong 2D velocity heterogeneity in the top 20 m. While these ...
(RC) buildings in this project, 6- and 12-story frames of representative buildings are modeled in this research paper. The response spectrum analysis is deployed for a multi-degree-of-freedom system exposed to seismic waves (earthquake) in the City of Vancouver. Hence, the seismic nature of ...
To map Earth146;s interior, geologists use a network of seismometers to chart seismic waves that originate in the earth146;s crust and ricochet around its interior, most rapidly traveling through cold, dense regions and slower through hotter rocks._
