Question

Plates are puzzle-piece like sections of the lithosphere that move over the asthenosphere, carrying pieces of continental and oceanic crust.

Which statement about the plates can geologists assume is true?


The plates are less than 70 km in thickness.

The plates assist in forming Earth’s magnetic field.

The plates are denser than the oceanic crust.

The plates experience little pressure from the weight of rocks.

Answer 1

The statement which geologists assume is true is that plates are denser than the oceanic crust.

 A section of lithosphere which slowly moves over the asthenosphere, carrying pieces of continental and oceanic crust.
Seafloor spreading is termed as the process by which molten material adds new oceanic crust to the floor of oceans. A divergent boundary is where plates move away from each other by forming rift valleys or oceanic ridges.

Answer 2

your answer would be C, The plates are denser than the oceanic crust. :D
