What are 2 geological features that can occur at plate boundaries?
Two geological features that can occur at plate boundaries are mountain ranges, formed from the collision of two plates, and deep ocean trenches, formed at subduction zones where one plate is forced beneath another.
What geological process occurs at a oceanic continental plate boundary?
At an oceanic continental plate boundary, a process called subduction occurs, where the denser oceanic plate is forced beneath the less dense continental plate due to the difference in their densities. This leads to the formation of deep oceanic trenches and volcanic arcs on the overriding continental plate.
What physical feature occures along ocean trenches and ridges?
The physical feature that occurs along ocean trenches and ridges is seafloor spreading. This process is when new oceanic crust is formed at mid-ocean ridges through volcanic activity, pushing the older crust away from the ridge towards ocean trenches where it is eventually subducted back into the mantle.
How do ocean ridges and deep-sea trenches support the theory of sea floor spreading?
Ocean ridges and deep-sea trenches support the theory of sea floor spreading through the process of plate tectonics. At ocean ridges, new oceanic crust is formed as magma rises and solidifies, pushing the existing crust apart. Deep-sea trenches are areas where old oceanic crust is being subducted back into the mantle, completing the cycle of sea floor spreading. This continuous movement of crust at ridges and trenches provides evidence for the theory of sea floor spreading and the movement of tectonic plates.
Is subduction occuring at ridges or trenches?
Subduction occurs at trenches where one tectonic plate is forced underneath another plate. Ridges, on the other hand, are locations where tectonic plates are moving apart and new crust is being created.
Where do midocean ridges intersect the landmasses?
Midocean ridges are areas where continents broke apart. Midocean ridges are closest to the landmasses in younger oceans. One example where a midocean ridge intersected a landmass is the Arabian sea, which was formed by the pulling apart of the Arabian Peninsula and Africa.
Where are the midocean ridges offset the most by faults?
At transform faults or transform zones.
Does the theory of continental drift state that ocean crust is formed at ocean ridges and destroyed at deep sea trenches?
Yes
Does theory continental drift state that new ocean crust is formed at ocean ridges and destroyed at deep sea trenches?
No, the theory is that Seafloor spreading state that the new ocean crust is formed at ocean ridges and is destroyed at deep sea trenches.
What theory explains the processes that shape the Earths surface into mountains deep sea trenches and oceanic ridges?
the theory of sea floor spreading or continental drift
Is the Mid-Oceanic Ridge in the middle of the Atlantic Ocean?
One of the midocean ridges is, but others are in other oceans, seas, and bays.
How is the formation of mid-ocean ridges and trenches different?
Mid-ocean ridges form at divergent boundaries where tectonic plates are moving apart, allowing magma to rise from the mantle and create new oceanic crust. Trenches form at convergent boundaries where one plate subducts beneath another, creating deep oceanic trenches due to the sinking of the denser plate back into the mantle.
What are valleys between the ridges on the ocean floor?
They are called oceanic trenches.
Do Ocean sediments become younger or older away from midocean ridges?
Older, as it moves away from the mid-ocean ridge the sediment gets thicker and older
How do you contrast mid-ocean ridges and trenches?
Mid-ocean ridges are the birthplace of oceanic crust. Trenches represent the destruction and burial of oceanic crust. They are at opposite ends of the Earth's convection currents that move through the asthenosphere.
