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

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

Mantle

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

Convection current in the mantle

What feature is created along the plate boundary when a plate subducts underneath another plate?

trench

Lithosphere is made up of ___________.

Crust and Upper mantle

Why is the inner core solid?

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

In a convection current, hot materials move ______________.

upward

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

force where actual seafloor spreading occurs

Name the type of movements on the Earth's crust.

DIVERGENT, CONVERGENT, TRANSFORM

Where do most new oceanic crust form?

at mid-ocean ridges

Compare the densities of the Earth’s crust, mantle, and core?

The mantle is less dense than the core but denser than the crust.

Why does oceanic plates go beneath continental plate?

Oceanic plate is denser than continental plate.

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.

This geologic features can be observed in a place where two oceanic crusts diverge.

RIFT VALLEY

Which crust is most likely to subduct?

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

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

Transform fault boundary
