They are at right angles because the spreading occurs at right angles to the ridges. If you look you will see that the faults happen at places where the ridges bend and they allow for the differential movement required.

Not true. If the associated central angles are equal, the two chords would be equal.

Beam spreading is when the sun's rays (or angles) spread out because the earth is in it's revolution and rotation. However this is the definition of beam spreading relating light and the amount of light received to earth, not relevant to another meaning. So basically beam spreading is when the sun's light spreads on earth.
The bond angles in IF4^- (iodine tetrafluoride) are approximately 90 degrees.
If the heptagon is regular the angle measurement for three angles would be approximately 385.7

They are all boundaries between or fractures within the Tectonic Plates forming the Earth's crust. A convergent boundary is that between two approaching plates; usually an ocean-floor plate being subducted beneath the continental plate as the ocean closes. This is happening now to the Pacific Ocean. A divergent boundary is the opposite: the fracture of plate into two parts moving away from each other. The break is closed by upwelling magma. E.g. The Mid-Atlantic Ridge - the Atlantic is presently widening away from this subsea mountain-range at a mean rate of about 25mm/yr. Transform boundaries, or Transform Faults, are shear fractures across the plate at roughly right-angles to the spreading-ridge from which the emanate. They represent the effect of unequal spreading forces. If you look at a relief map of the Atlantic Ocean bed you will see many transform faults to E and W of the Mid-Atlantic Ridge
They do not have the same solid angles. Also, CH4 has five atoms while H2O has three.
No, the bond angles in NH3 are approximately 107 degrees.
Sydney to Los Angles would be approximately 12051 KM. Sydney to New York City would be approximately 15992 KM.
