Geophysics is the measurement of contrasts in the physical properties of materials beneath the surface of the earth and the attempt to deduce the nature and distribution of the materials responsible for these ovservation.For example,variations in elastic moduli and density cause seismic waves to travel at different velocities through different materials variations in the electric conductivity rocks and sediments produce varying values of apparent resistivities as the distance measuring probes is changed on the surface,and density variation in the subsurface lead to variation in gravitational acceleration at surface insstrument stations.

地球物理学测量地表以下物质物理特性对比度并尝试推导出符合这些特征的物质特性及其分布.比如,弹性和密度的不同促使地震波在不同的物质中传播的速度不同.随着地表遥测探针的变化,岩石和沉积物导电特性的不同会产生电阻系数的明显差值.地表下密度的变化会导致地面仪器站里重力加速度的变化.
