Scientists have used seismic waves from earthquakes to study the Earth's interior. By analyzing how these waves travel through the Earth, scientists have been able to determine the density and composition of different layers like the crust, mantle, and core. Additionally, studies of meteorites and laboratory experiments have provided further insights into the Earth's composition.

How have scientists determined the age of earth?
Scientists have determined the age of the Earth using various methods, most notably radiometric dating of rocks and minerals. By measuring the decay of certain radioactive isotopes within these materials, scientists are able to calculate the age of Earth to be approximately 4.54 billion years old.
How did scientists determined that the earth was made 4.567 billon years ago?
Scientists determined the age of the Earth by studying the decay of radioactive isotopes in rocks and meteorites. By measuring the ratios of certain isotopes in these samples, they were able to calculate an age of approximately 4.567 billion years. This technique is known as radiometric dating.
What do scientists study to learn about the temperature inside the earths crust?
Scientists study seismic waves to learn about the temperature inside the Earth's crust. By analyzing the speed and direction of these waves as they travel through different layers of the Earth, scientists can infer information about the temperature and composition of the Earth's crust.
What is the age of the earth that is accepted by most scientists?
Most scientists accept that the Earth is approximately 4.5 billion years old. This age is determined through radiometric dating of rocks and meteorites, among other methods.
How did scientists determine Earth has layers?
Scientists determined that Earth has layers through various methods such as studying seismic waves from earthquakes, analyzing samples from drilling projects like the Deep Earth Sampling, and studying the behavior of materials under high pressure and temperature in laboratory experiments. These methods provide evidence for the composition and properties of Earth's layers, including the crust, mantle, outer core, and inner core.
Why do scientists study rocks in order to study the inside of the earth?
Types of rocks are inside the Earth, so scientists study them.
Who do scientists figure out what inside earth?
by digging holes in the earth

How do scientists find out information on the core?
Scientists find out information on the core by using special tools to dig out samples from deep inside the earth. Special instruments "look inside" parts of the earth we cannot see.
How do we know the mass of the Earth?
The mass of the Earth is determined by measuring the gravitational pull it exerts on objects. Scientists use the laws of physics and observations of the Earth's orbit to calculate its mass.
How did scientists determined that the earth was made 4.567 billon years ago?

Scientists determined this was expanding by using the spectrograph?
Scientists determined that the object was expanding by analyzing its light spectrum using a spectrograph. By observing the Doppler shift in the spectral lines, scientists could infer the motion of the object relative to Earth, leading to the conclusion that it was moving away and expanding.
How did scientists determine that the Earth's mantle existed?
Scientists used detectors which determined the mantle existed. As well, scientists must hypothesize and theorize what cannot be readily seen, and make determinations based on the evidence that does exist.
What do scientists study to learn about the temperature inside the earths crust?
Scientists study seismic waves to learn about the temperature inside the Earth's crust. By analyzing the speed and direction of these waves as they travel through different layers of the Earth, scientists can infer information about the temperature and composition of the Earth's crust.
Explain why its impossible to ever really know the materials compose earth's interior?
Scientists have determined what the interior of the earth is like through analyzing seismic or earthquake wave
Earth scientists assume that the causes of natural events or phenomena can be determined by?
Earth scientists assume that the causes of natural events or phenomena can be determined by observing patterns, collecting data, and analyzing evidence. They use methods such as experimentation, modeling, and field studies to understand the underlying processes driving these events. By studying these factors, scientists aim to develop theories and explanations that can help predict and mitigate future events.
How do scientists know the inside of the earth is made of layers?
each layer in earth has diffrent material that is cuse diffrent propertis. natural or man made Wave when it come from inside of the earth show difftent propertis .this is main reason of layering earth .
