# Geophysics

Geophysics is an interdisciplinary subject which studies the Earth and its environment in space. Geophysicists will study the Earth by using quantitative physical methods. Geophysics can also refer to geological applications. Geophysics looks at the Earth’s shape, its gravitational and magnetic fields, its internal structures and composition, its dynamics and their surface expression in plate tectonics, the generation of magmas, volcanism and rock formations.

Geophysics can be applied to meet society’s requirements. It has been used in mineral resources, mitigation of natural hazards and environmental protection. Geophysics can also be utilized by surveying the land to analyze potential petroleum reservoirs and mineral deposits, locate groundwater, find archaeological relics, determine the thickness of glaciers and soils, and assess sites for environmental remediation.

### Rocks: Solid Earth

I have studied Bowen's reaction series and understand the process of magmatic differentiation, that different types of minerals crystallize from magma systematically. I understand that during the crystallization process, the composition of magma continually changes. However, can you explain and help me understand how partial me
