Question

Which is one type of evidence that geologists usually study

Answer 1

Geologists have used two main types of evidence to learn about Earth's interior: direct evidence from rock samples and indirect evidence from seismic waves.

Answer 2

QUESTION:-

Which is one type of evidence that geologists usually study?

ANSWER:-

• Indirect evidence is one type of evidence that geologists usually study.

EXPLANATION:-

• Geologists can not be able to see what is inside Earth which is why they have relied on indirect evidence techniques for observation.

• When a heavy picture is being hung on a wall, the person hanging it first knocks on the wall to find the wooden beam that is underneath the plaster to support the picture. While knocking the person carefully listens to know the change in the sound to fit the picture to the wooden bean

• For studying the interior of Earth's surface, geologists similarly use an indirect evidence technique. However, rather than knocking on walls, they use seismic waves. During the occurrence of earthquakes, they generate seismic waves. These seismic waves are recorded by Geologists for studying how these waves travel to the interior of Earth.

• Several classifications of seismic waves function differently. The wave's speed and the paths that are taken by the waves disclose the arrangement of the planet.

• With the help of seismic waves, geologists have discovered that the interior of Earth is composed of layers. Each layer is surrounded by another layer underneath it.
