Regents Earth Science - Plate Tectonics and The Interior

Front

What is the outer core of the Earth composed of?

Back

The outer core is composed of liquid iron and nickel.

Front

How do P waves and S waves behave in the outer core?

Back

P waves can travel through the outer core, while S waves cannot.

Front

What type of rock primarily makes up the continental crust?

Back

The continental crust is primarily made up of granite.

Front

What is the significance of the ocean ridge in plate tectonics?

Back

The ocean ridge is a divergent boundary where new oceanic crust is formed.

Front

Who is credited with proposing the theory of continental drift?

Back

Alfred Wegener proposed the theory of continental drift.

Front

What is the composition of the inner core of the Earth?

Back

The inner core is composed of solid iron and nickel.

Front

What is the difference between oceanic crust and continental crust?

Back

Oceanic crust is primarily basalt, while continental crust is primarily granite.

Front

What evidence supports the theory of plate tectonics?

Back

Evidence includes the fit of continents, fossil distribution, and seismic activity.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle.
