Agroup of scientists studied seismic waves and observed that the speed of seismic waves changes as they travel deeper into the earth. based on the scientists' observations, it can be concluded that earth may have layers made of the same materials empty caverns deep under earth's crust the same density throughout layers of different densities

Ответ:
Based on the scientists' observations, it can be concluded that there may be empty caverns deep inside the Earth's crust and also layers of different densities.
Explanation:
The layers beneath the Earth's surface are distinctly dense. Some layers possess very high density, while some are comparatively less dense. The seismic waves travel at different speeds through layers of different densities. These waves even disappear while penetrating through some layers. This allows scientists to draw solid and reliable conclusions about the formation of the Earth's interior.Ответ:
After Mars, there is an asteroid belt that separates the inner planets from the outer ones. The outer planets are called the jovian planets, meaning huge gas giant. These planets in order are Jupiter, Saturn, Uranus, and Neptune. Pluto comes after Neptune, but it is no longer considered a planet.
