The length of time between polar shifts, the distance from the mid-oceanic ridge, the width of the adjacent stripes, and the direction the iron particles are aligned are all irrelevant information for calculating the speed a plate is moving if the width of the magnetic stripe is known.
To calculate the speed a plate is moving, in addition to knowing the width of the magnetic stripe, you need to know the length of time between polar shifts and the width of the adjacent stripes.
To calculate the speed at which a plate is moving, in addition to the width of the magnetic stripe, you also need the following information:
1. The length of time between polar shifts: Earth's magnetic field undergoes periodic reversals, known as polar shifts. By knowing the time it takes for one polar shift to occur, you can determine the rate of plate movement.
2. The distance from the mid-oceanic ridge: The mid-oceanic ridge is a range of undersea mountains that runs through the center of the ocean basins. The rate of seafloor spreading, which is related to plate movement, can be determined by measuring the distance between the magnetic stripe and the mid-oceanic ridge.
3. The width of the adjacent stripes: Magnetic stripes on the ocean floor occur in a pattern where alternating stripes have opposite magnetic orientations. By considering the width of both the known stripe and its adjacent stripes, you can calculate the rate of plate movement.
4. The direction the iron particles are aligned: The alignment of iron particles within the Earth's crust provides information about the magnetic field's orientation when the rock was formed. By studying the direction of the aligned particles in the magnetic stripe, you can ascertain the direction and speed of the plate movement.
So, by combining the width of the magnetic stripe with these additional pieces of information, you can calculate the speed at which a plate is moving.
