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.


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.


What is the difference between trench and ridges?

Trenches are long, narrow depressions in the Earth's surface, usually formed by tectonic activity or erosion. Ridges, on the other hand, are elevated areas or lines along the Earth's surface, often created by the movement of tectonic plates or the accumulation of sediment. In simple terms, trenches are valleys, while ridges are peaks or elevated areas.

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.

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.

Are maps made from sonar and magnetometer data led to the discovery of ocean ridges and deep-sea trenches?

Yes, sonar and magnetometer data have been instrumental in the discovery of ocean ridges and deep-sea trenches. Sonar data is used to map the sea floor topography, revealing ocean ridges, while magnetometer data helps identify variations in the Earth's magnetic field caused by stripes of rock on the ocean floor, contributing to understanding plate tectonics and the formation of deep-sea trenches.
