What evidence supports Wegener's Theory? Give at least 2.

sides of continents fit together, same fossils found on different parts, mineral and rock formation

What is the driving force that facilitates the movement of the lithospheric plates?

Convection current in the mantle

What did scientists conclude when they discovered that stripes of ocean floor leading away from the crest showed polarities that alternate between normal and reversed?

That the earth‘s magnetic field must have flip-flopped many times since its formation.

What element is abundant in the earth’s crust?

Oxygen

Why is the inner core solid?

The inner core is solid because of pressure exerted by Earth’s outer layers.

In which layer of the earth does convection current take place?

Mantle

Which crust is most likely to subduct?

The older, the denser plate will subduct beneath the less dense plate.

What is the role of the mid-ocean ridge in the movement of lithospheric plates?

force where actual seafloor spreading occurs

San Andreas fault found in North American Plate is what type of plate boundary?

Transform fault boundary

Where do most new oceanic crust form?
