SOLAR SYSTEM

Detailed explanation-1: -The study of seismic waves is known as seismology. Seismologists use seismic waves to learn about earthquakes and also to learn about the Earth’s interior. One ingenious way scientists learn about Earth’s interior is by looking at earthquake waves.

Detailed explanation-2: -So scientists rely on seismic waves-shock waves generated by earthquakes and explosions that travel through Earth and across its surface-to reveal the structure of the interior of the planet. Thousands of earthquakes occur every year, and each one provides a fleeting glimpse of the Earth’s interior.

Detailed explanation-3: -These recordings made by a seismograph are called seismograms. Seismic waves travel at different speeds when they pass through different types of material, so by studying seismograms, scientists can learn a lot about Earth’s internal structure.

Detailed explanation-4: -P waves can travel through liquid and solids and gases, while S waves only travel through solids. Scientists use this information to help them determine the structure of Earth. For example, if an earthquake occurs on one side of Earth, seismometers around the globe can measure the resulting S and P waves.
