Iron in Earth's Core Weakens Before Melting

This informational text resource is intended to support reading in the content area. Researchers have created models that can be used to understand previously unexplained properties of the Earth's core. Previously, we have not been able to explain the behavior of seismic waves traveling through the core. However, a new model suggests that the iron in the core greatly weakens before melting, which slows the waves down.
