Question

sources of evidence in studying the interior structure of the earth

Answer 1

Answer:

Explanation:

Indirect sources include meteors that at times reach the earth, gravitation, magnetic field, and seismic activity. Most of our information about earth's interior has come from seismic studies. Seismic waves produced during an earthquake are recorded by a seismograph when these waves reach the surface of the earth

Answer 2

There are both indirect and direct evidence to study the interior structure of the earth

Explanation:

• The knowledge of the interior structure of the earth is obtained from direct and indirect sources. The direct sources include the rock's materials as molten rocks from the volcanic eruption and the deep oceanic drilling studies.

• The indirect sources include the meteoroids that at a time reach by the earth's gravitational and magnetic fields and seismic activity.

• The seismic activity produced is recorded in the seismograph that shows the earth waves P and S that are due to the release of the energy from the earth.

• The P waves travel by all the mediums and S waves can through the solid mediums, places were we don't get any waves is a sign of discontinuity or a shadow zone that exists between the layers of the earth. Thus on the behavior of the waves the following structure has been identified as.

• The Lithosphere thin sheet of plate tectonics is brittle and has a thickness of 5 to 200 km, followed by asthenosphere that is ductile and has 100 to 300 km, mantle (upper) 300 to 400 km.

• Are rigid and density increase with depth, mantle (lower) is denser and is rigid at 23,00 km and core outer liquid state and inner in solid and rigid.
