Scientists send seismic waves through the earth. These travel at different speed according to the density of the material that they travel through. When they bounce back, scientists use these data to guess what the earth is made up of.

∙ 12y agoMuch of what is known about the earth's layers comes from measuring seismic waves caused by earthquakes or massive explosions. As these waves move through different substances, their properties change, allowing scientists to estimate the depths and compositions of different layers of the earth.

Why do scientists believe that the earth developed in a series of layers?
because the earth as it builds up over time new layers formed from the techtonic plates each layer probobly has their own plates but not discovered yet and when convergent bounderies made mountains and more land, the earth made new layers that were capable of living on
How did scientists figure that the earth was made of layers?
Scientists used seismic waves to discover the layers of Earth.
How do scientists learn about the layers of Earth?
no
Four layers of an equatorial forest?

How do scientists believe the layers of the earth were formed?
dust and ice and other partcials

What methods did geologist used when they first developed the geologic time scale?

Scientists believe that the iridium found in some rock layers may originally have come from a?
Meteorite. An asteroid is probably a better description of the thing that hit Earth.

4
How did scientists determine Earth has layers?
Scientists determined that the Earth has layers through studying how seismic waves travel. These seismic waves differed depending on how thick the layer was.
What methods did geologists use when they first developedthe geologic time scale?
Scientists first developed the geologic time scale by studying rock layers and index fossils worldwide. With this info. (information if you forget!), scientists placed Earth's rocks in order by the relative age.
What kind of scientists would study the earth's layers?
Geologists
