Ocean ridges can be found at divergent boundaries where two plates are moving away from each other. As the magma rises to fill the void, it cools into rock and forms new crust. The iron minerals in the rocks align with the earth’s magnetic field before the rock cools. This causes the rocks in these areas of seafloor spreading to have band-like patterns. The irons align differently each number of years in relation to the flipping of the earth’s magnetic field. This phenomenon has been used to determine the ages of these rock layers.
O=height of monument
tan32= O/405
O=tan32/405
height of monument=0.0015 ft.
Because the rays of the sun gives off a stronger brightness.
Also people want to see the effect of the eclipse and are dumb enough to stare at it, which u really can't due to such brightness.
