WebAn earthquake is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge … WebD) crust. B) lithosphere. Plate tectonics states that. A) the continents move through Earth's crust like an icebreaker through ice. B) earthquakes occur because tectonic plates break like a dropped dinner plate. C) tectonic plates have not moved since Pangaea broke up. D) tectonic plates are in slow, but constant motion.

Webasthenosphere, zone of Earth’s mantle lying beneath the lithosphere and believed to be much hotter and more fluid than the lithosphere. The asthenosphere extends from about 100 km (60 miles) to about 700 km (450 miles) below Earth’s surface. crustal generation … subduction zone, oceanic trench area marginal to a continent in which, … earthquake, any sudden shaking of the ground caused by the passage of … convection, process by which heat is transferred by movement of a heated … lithosphere, rigid, rocky outer layer of the Earth, consisting of the crust and the … tectonic landform, any of the relief features that are produced chiefly by uplift or … magma, molten or partially molten rock from which igneous rocks form.

The seismic waves created by the earthquake were so strong that scientists were able to measure them closely and prove that they moved differently through the asthenosphere …
WebWhere do these earthquakes most likely occur? on land but close to oceans inland, far from the coast in the middle of the oceans anywhere there are mountains on land but close to oceans During the process of mountain building, earthquakes sometimes occur along continental-continental convergent boundaries. WebMost earthquakes and volcanoes occur where the moving plates interact along their boundaries, and at hotspots. Evidence for Tectonic Plates The continents are blocks of thick crust that are passengers on the tops of large tectonic plates (lithosphere) that move over a softer part of Earth’s mantle (asthenosphere).
WebThe asthenosphere is a layer of low rigidity that separates the rigid lithosphere from the rigid mantle. Most of the Earth's volcanic and earthquake activity occurs at the edges of lithospere plates. The eastern edge of the North American continient is not the same as the eastern boundary of the North American plate. WebWhat layer of the earth provides the heat that causes convection to happen? 5.) As the plates continue to move, what other geologic event could take place? 9. what geologic features and events are evidences of the movement of the tectonic plates? 10. Q5. What are the geologic Processes/events that will occur because of this plate movement?Q6.
WebEarthquakes occur in the lithosphere, not in the asthenosphere There is no sharp boundary between the lithosphere and asthenosphere. The Earth gets gradually hotter as you go deeper, so the viscosity of rocks gradually gets smaller. On the other hand, the crust and mantle are different rock types.

Active faults are concentrated in the zones that form plate boundaries. Elastic Rebound Theory How earthquakes are generated. Stresses cause strain to build up in rocks until they can no longer bend elastically and they break, causing an earthquake. portmeirion in walesWeb7. In this exercise, you will explore the dynamics that power plate tectonics.
