Question

Magnetic stripes on the seafloor are caused in part by:

A. declination of the poles.
B. tidal forces.
C. movement of ocean crust.
D. gravity.

Answer 1

Option C, movement of ocean crust.

Step-by-step explanation:

When ocean crust are moved apart from each other , the magma with in the earth crust rises to the surface of mid-ocean ridges. This magma being unstable is spilled off. All ferromagnetic minerals with in the earth crust align themselves along the spilled hot magma thereby reversing its north-to-south polarity very frequently. As the magma cools down the polarity gets constant and confined. Later on when the magnetic field flips again, new ocean floor again aligns its polarity in opposite direction.

Hence, option c is correct.

Answer 2

Hey there!

• 
  `\bold{A.}` declination of the poles is the vertical axis of the globe which starts at the degrees of 0
  `\bold{\leftarrow{incorrect}}`
• 
  `\bold{B.}` tidal forces is the force which reaches/ stretches for the body water that is towards from the middle of the mass from another body of water
  `\bold{\leftarrow{incorrect}}`
• 
  `\bold{C.}` movement is the magnetic stripes on the seafloor that is caused in the part
  `\bold{\leftarrow{CORRECT!!!!}}`
• 
  `\bold{D.}` gravity is force
  `\bold{\leftarrow{Incorrect}}`

•
