How Does the Structure of the Earth Affect Earthquakes and Volcanoes?

The structure of the Earth plays a significant role in the occurrence of earthquakes and volcanoes. The Earth's crust is divided into tectonic plates, which are in constant motion. When these plates collide or slide past each other, it can result in seismic activity such as earthquakes and volcanic eruptions. Additionally, the Earth's mantle, which is semi-fluid, can cause pressure buildup beneath the Earth's surface, leading to volcanic activity. Understanding the Earth's structure is crucial in predicting and preparing for these natural events.
