Our living hollow earth by rodney m cluff this knowledge should generate within us a deep respect for the planet upon which we live which provides us our home . More detailed knowledge of the structure of the earths interior comes from observations of seismic waves when an earthquake happens, it releases energy that travels through the earth in all directions as seismic waves. Earth's interior, like that of the other terrestrial planets, is divided into layers by their chemical or physical from new moon to new moon, is 2953 days. Knowledge of other earths in the universe, and its relation to the new dispensation it has been a question which has interested the human mind, whether the globes which compose our planetary system and the starry universe, are inhabited by rational beings like ourselves.

Advances in imaging the interior of earth have revised conceptions of how the planet formed and continues to evolve vast amounts of new data, especially from satellites, together with modern computational models, are revealing the complexity of the interacting systems that control earth’s ever-changing surface. Is about the earth`s interior and plate tectonics(we should know it by memory,we have gone over thesequestions more than 1000 times). It is widely accepted that the earth’s interior is composed of several layers: the crust, the mantle and the core since the crust is readily accessible, scientists have been able to perform hands-on experiments to determine its composition studies on the more distant mantle and core have more limited opportunities samples, so scientists also rely on analyses of seismic waves and gravity . A look at the layers of the inner earth studying the earths interior can help us to understand earthquakes, volcanoes, plate tectonics and more about the inner earths natural processesthese layers of the earth interact in ways that affect life on the earth.

Earth keeps a nearly steady temperature, because it makes heat in its interior in other words, earth has been losing heat since it formed, billions of years ago the earthsky team has a blast . The inner earth is composed of three main parts, sometimes called the layers of the earth the crust, the mantle, and the core as shown in the diagram of the earths interior below: the crust - silicate rocks, primarily granite and basalt oceanic crust - mostly basalt continental crust - igneous, metamorphic, and sedimentary rocks. The main way that scientists have been able to determine the makeup of the interior of the earth is by studying how seismic waves pass through its various layers in addition, they have also made theories about the composition of the core of the earth by studying its magnetic fields scientists know .
The distance from earth's surface to its center is about 3,975 miles (6,395 kilometers) scientists have divided the interior of earth into various layers, based on their composition the crust, or outer portion, varies in depth from 5 to 25 miles (8 to 40 kilometers) below the crust is the mantle .
