How are ocean ridges and trenches related? Describe their relationship in
True [87]

Terms that are asked to be used in the response are bolded;

     Ocean ridges and trenches are related in a few ways. One of the ways is being created from the movement of tectonic plates on the mantle when they diverge and converge. When tectonic plates diverge they "pull apart" and create trenches. When they converge they "push together" and create ridges, subduction happens here. The tectonic plates move on the mantle of magna from convection currents creating these different boundaries.

Have a nice day!

The surface indentation that separates the atria from the ventricles is known as the?
Lerok [7]

Atrioventricular septum is the surface indentation that separates the atria from the ventricles.

<h3>What is an atrioventricular septum? </h3>

The interatrial and interventricular septal cross the atrioventricular annular plane and merge with the septum tricuspid and anterior mitral leaflet attachment at the septal atrioventricular junction, which is a critical region of the heart.

The tricuspid and mitral valves seem cruciate on a four-chamber view when both septa are converging, earning the term crux of the heart, cardiac crux, or crux cordis.

The atrioventricular septum, a septal component dividing the atria from the left ventricle, is a distinctive anatomic characteristic of the atrioventricular junction.

Therefore, the atrioventricular septum is the indentation that separates the atria from the ventricles.
