GEOLOGY

Detailed explanation-1: -They can move at rates of up to four inches (10 centimeters) per year, but most move much slower than that. Different parts of a plate move at different speeds. The plates move in different directions, colliding, moving away from, and sliding past one another. Most plates are made of both oceanic and continental crust.

Detailed explanation-2: -The lithospheric plates move at about 5 km per year. on the ocean floor. Convergent Boundaries (pages 265–267) 5. At convergent boundaries, plates and interact.

Detailed explanation-3: -The average rate of plate movement is approximately 5 cm/yr (about as fast as fingernails grow). This rate is perceptible but only over a long time.

Detailed explanation-4: -Lithospheric Plates move at different speeds depending upon the exposure to the convection currents it experiences from within the mantle. The fastest-moving plate is drifting at an approximate speed of 10 cm/year while the slowest moving plate is moving at the speed of around 1 cm/year.

Detailed explanation-5: -Due to the convection of the asthenosphere and lithosphere, the plates move relative to each other at different rates, from two to 15 centimeters (one to six inches) per year.
