Was the sea floor off the coast of Newfoundland a likely site for earthquakes Why?
Yes, the sea floor off the coast of Newfoundland is a likely site for earthquakes due to its location along the boundary of the North American and Eurasian tectonic plates. These tectonic plates interact in ways that can cause stress and lead to seismic activity. Additionally, the region has been historically associated with seismic events, highlighting its vulnerability to earthquakes.
Do earthquakes trigger tsunami's?
Tsunami's can be triggered by earthquakes that happen underneath the ocean floor.
What causes tsunami and earthquakes in Japan?
Earthquakes in Japan are caused by the movement of tectonic plates. A tsunami is a large ocean wave that is caused by sudden motion on the ocean floor which can be triggered by earthquakes.
What happens when an earthquake originates under the sea floor?
earthquakes under seafloor can lead to tsunamis
Earthquakes that originate beneath the ocean floor produce huge tidal waves called .?
tsunami
Which feature of the ocean floor is shallow and close to the edge of the continent?
pie
What Deep focus earthquakes are associated with what prominent ocean floor feature?
Deep focus earthquakes are primarily associated with subduction zones, which are often located near oceanic trenches. These trenches, such as the Mariana Trench or the Japan Trench, occur where one tectonic plate is being forced beneath another, leading to deep seismic activity. The depth of these earthquakes typically ranges from 300 to 700 kilometers, reflecting the conditions of the subducting slab.
Which feature best marks the edge of a continent?
The expanse of land known as a 'continental shelf' where seawater is shallow, before it drops off into the ocean.
What ocean-floor feature is associated with areas where oceanic crust is broken down?
The mid ocean ridge is the area of the ocean floor that is associated with the breaking down of the oceanic crust. This area is known for seafloor spreading.
What are the features of the ocean floor?
The ocean floor is irregular as to the land we can see. It has mountains and ridges and plains and valleys and volcanoes. It even has underwater earthquakes, and just about every other land feature you could name.
What is shallow ocean floor near the shore?
THE SHELF
What sea floor can algae survive on?
shallow areas
Was the sea floor off the coast of Newfoundland a likely site for earthquakes Why?
Yes, the sea floor off the coast of Newfoundland is a likely site for earthquakes due to its location along the boundary of the North American and Eurasian tectonic plates. These tectonic plates interact in ways that can cause stress and lead to seismic activity. Additionally, the region has been historically associated with seismic events, highlighting its vulnerability to earthquakes.
What are offshore trenches?
Offshore trenches are deep, elongated depressions on the ocean floor formed by the collision of tectonic plates. They are typically associated with subduction zones where one tectonic plate is forced beneath another, creating a trench-like topographic feature. Offshore trenches play a vital role in plate tectonics and are often sites of earthquakes and volcanic activity.
Why the earth quack come in new zealand commonly?
New Zealand experiences about 300 earthquakes of Richter 4 to 4.9 each year, (on average); and an average of two in the range Richter 6 to 6.9.There is a huge difference in the distribution of Deep and Shallow earthquakes, and this is illustrated by graphs in the website of gns.cri.nz.Of course, the shallow earthquakes have a very much greater effect on structures.The very deep earthquakes are commonly in Fiordland, where the population is very low. The deep earthquakes in both islands are strongly associated with the subduction of the Pacific plate under the Australian Plate in the north; and the subduction of the Australian plate under the Pacific Plate in the South.As far as deep earthquakes are concerned, there is a quiet zone where these patterns cross over, and this raises the Southern Alps.New Zealand straddles the boundary between these two plates. The Alpine Fault in the South Island may be an extension of a transcurrent fault associated with the Mid Ocean Ridge sea floor spreading in the south Pacific.This fault continues through New Zealand, emerging as the Hikurangi trench, which becomes the Tonga Trench further north again.
Do earthquakes trigger tsunami's?
Tsunami's can be triggered by earthquakes that happen underneath the ocean floor.
How are earthquake patterns used to provide evidence of sea floor spreading?
Earthquake patterns, including their depth and distribution, can provide evidence of sea floor spreading by showing a concentration of earthquakes along mid-ocean ridges where new oceanic crust is being formed. As tectonic plates diverge and new crust is created, stress builds up and is released through earthquakes. The pattern of earthquakes along mid-ocean ridges provides a visual representation of the tectonic activity associated with sea floor spreading.
