Creep meters and laser-ranging devices measure horizontal fault movement. t and f

The given statement is true.

Creep meters and laser ranging devices are used to measure horizontal fault movements. Creep meter is a device which is used to measure how far the ground has moved in a horizontal direction over an active fault. It works by using a wire across the fault. As the ground move in the horizontal path the change in position is measured. Laser-ranging device uses a laser beam of light & reflector to detect  the horizontal fault movements.

format change of dna.  

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !
