Earth’s Layers
Core: The inner zone of higher temperature and density, occupying 17% of Earth’s volume. The high temperature is due to the disintegration of uranium and other radioactive elements.
Mantle: Occupies 82% of Earth’s volume with a density slightly lower than the core. Mostly solid except for the asthenosphere, located between the mantle and crust. Convection currents within the asthenosphere move the tectonic plates of the lithosphere.

Roman Architecture and Engineering
Key Innovations
Rome’s architectural prowess stemmed from their innovative use of the arch and vault, evident in structures like the Pantheon. They also developed the composite capital, blending Ionic scrolls with Corinthian acanthus leaves. Another Roman creation was the Tuscan order, a simplified Doric style with a base, smooth shaft, and a smaller, more intricate capital.
Temples
Roman temples, unlike their Greek counterparts, were rectangular and elevated on
