geophysics
n. uncountablen. the study of the physical processes and properties of the Earth and its surrounding space. Scientists in this field look at things like earthquakes, the Earth's magnetic field, and how the planet moves.
n. the branch of geology concerned with the physical properties and processes of the Earth and its surrounding space. It encompasses the study of seismic activity, gravity, magnetism, and the Earth's internal structure.
She decided to study geophysics to understand how earthquakes happen.
The university's geophysics department uses advanced sensors to monitor seismic activity deep beneath the ocean floor.
By analyzing the propagation of seismic waves through the Earth's mantle, geophysics provides critical data for understanding the planet's internal heat flow and tectonic plate movements.
