A. the inner and outer core B. the atmosphere and crust C. the lower mantle and outer core D. the crust and upper mantel © 2025 Renaissance Learning, Inc. All right ! testing.illuminateed.co

Did you know that the Earth's crust and the upper mantle together form the lithosphere? This solid, rigid layer is crucial because it’s not just any rock, but it’s broken into tectonic plates that float on the semi-fluid asthenosphere below. These plates are responsible for moving and can cause earthquakes and volcanic eruptions when they interact! In real life, understanding these layers and the behavior of tectonic plates helps scientists predict when and where earthquakes might strike. For instance, places situated along tectonic plate boundaries, like California with the San Andreas Fault, are known to experience more seismic activity, prompting preparedness and safety measures for the communities living there.
