The circular folds or plicae circularis are the permanent folds or ridges of the mucosa.

The areolar connective tissue layer is found deep to the mucosa in various parts of the body, including the digestive and respiratory tracts. It serves to provide support, protection, and flexibility to the mucosa layer. Additionally, it contains blood vessels, nerves, and immune cells important for tissue function and repair.
Mid-ocean ridges transfer energy from the mantle/asthenosphere/lithosphere to the surface. The energy is from the deep Earth.
The deep *vertical* lines in your fingernails are genetic. If you have *horizontal* ridges in your nails, you should see a doctor.
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.
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.
Compared to ocean crust near deep-sea trenches, crust near ocean ridges is generally younger, thinner, and hotter. Ocean ridges are sites of active seafloor spreading where magma rises to create new crust, while deep-sea trenches are associated with subduction, where older, denser crust is pulled back into the mantle. As a result, the crust at ocean ridges is also less dense and more buoyant than the crust found near trenches.
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.
