How gravitational force, magnetic field and seismic activity do helps to understand the interior structure of the earth?
Answers
Explanation:
Gravity and gravitation is a natural phenomenon by which all things with or energy _including planets, stars and even light.
........... Thus Gravity measurements the earth mass and tell us that the interior of the earth must be denser than the crust because the average density of earth is much higher than the density of the crust.
**A magnetic field is generated by electric current due to the motion of convection currents of a mixture of molten iron and nickel in the Earth's outercore : these convection currents are caused by heat escaping from the core,a natural process called geodynamo
**Seismic waves travel at different speeds when they pass through different types of material. So
by studying seismograms(used to detect and record earthquake). So by this we can learn a lot about Earth internal structure.
