Why do scientists believe that the earth is made up of different layers?

for the same reason that if you pour oil on top of a jar of water the oil stays on top. the layers of the earth have different densities and so the heaviest stuff sank to the center while the lighter stuff rose to the top.

Scientists believe that humans arrived on Earth during which Period?
A. Quaternary
Why have scientists not been able to physically explore all of the layers of the earth?
because they haven't quite gotten that far in technology to create a machine to go to the flaming hot center of the earth
What do scientists believe causes so many earthquakes in the middle of the Atlantic ocean?
scientists believe that the volcano and earthquakes activity in this area are due to the formation of new part of the Earth's crust along the ridge
How thick is each 8 layer of the Earth?
There are five basic layers of the Earth, being the crust, upper mantle, inner mantle, outer core, and inner core. Of these, the lithosphere is composed of the crust and upper mantle, and the asthenosphere is part of the mantle, below the lithosphere.
How does density change between the different layers of earth?
The deeper you get into the earth, the more weight you have above you. This results in pressure that increases the density of the material below.
How do scientists believe the layers of the earth were formed?
dust and ice and other partcials
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
Which layers have scientists been able to explore?
which layers of the earth have scientists been able to explore
How can scientists see what happened in the past by using the layers of earth?
It's because of the different levels of carbon or something.
Scientists believe that the Earth is presently overdue for an Ice Age?
Yes it is true that scientists believe that the Earth is presently overdue for an Ice Age. The Ice Age happens in different cycles.
Explain why scientists believe the Earth developed in a series of layers?
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.
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 kind of scientists would study the earth's layers?
Geologists
What is stratification and why is it important to earth scientists?
stratification- is the process of sediments forming layers it helps to tell scientists how old they are and when did they form on 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 scientists study the layers of the earth?
Scientists use their eyes where the layers have risen above ground and drill core samples to bring to the surface to study. Scientists use GPS tracking to study plate tectonics. by studying how seismic waves refract as they pass through different material.
