What are 2 geological features that can occur at plate boundaries?
What are three geographic features that may be found at plate boundaries?
What is the hypothesis that continents have moved slowly away from there current locations?
It was called "Continental Drift" and was promptly (and rightly) dismissed as it proposed that the Continents were somehow plowing through the solid rock of the Oceanic crust, like ships through the liquid water of the ocean. It took observations made by the US Navy during the 1950s (and kept classified secrets for many years), including volcanic activity of the midocean ridges, magnetic reversals in the Oceanic crust that were symmetric about the midocean ridges, and very deep ocean trenches. These showed that large moving plates existed in the earth's crust that transported both the Continents and sections of Oceanic crust in various directions. Ultimately this provided a workable mechanism that replaced the rejected "Continental Drift" hypothesis with the Theory of Plate Tectonics.
How do ocean ridges and deep-sea trenches support the theory of sea floor spreading?
Sea Floor spreading has to do with the crust forming at ocean ridges and being destroyed at deep sea trenches.
Is subduction occuring at ridges or trenches?
Subduction usually occurs in trenches, for example the Marriana's Trench or the Aleutian trench! Hope that Helps!
Explain what plate tectonics and ocean trenches have in common?
Ocean trenches and volcanoes both occur where continental plates collide, or meet. An Ocean trench is also noted for the presence of a volcanic arc. This is right no joke:)
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 are Continental margins near the edges of converging plates?
In the main along the mid oceanic ridges and along oceanic 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.
Are maps made from sonar and magnetometer data led to the discovery of ocean ridges and deep-sea trenches?
no they found ocean ridges sonar maps alone found deep-sea trenches
What are valleys between the ridges on the ocean floor?
They are called oceanic trenches.
How do ocean ridges and deep-sea trenches support the theory of sea floor spreading?
Sea Floor spreading has to do with the crust forming at ocean ridges and being destroyed at deep sea trenches.
