How Richard oldham discover that outer core of the earth was liquid?
Richard Oldham discovered that the outer core of the Earth was liquid through the analysis of seismic waves. He observed that certain seismic waves would not pass through the Earth's outer core, indicating it was a liquid layer that blocked those waves. This discovery revolutionized our understanding of the Earth's internal structure.
What two metals are found at the centre of the Earth?
Iron and nickel are believed to be the two main metals found at the center of the Earth. This is based on seismic data and the behavior of these metals under high pressure and temperature conditions similar to those found at the Earth's core.
Earth's core is likely composed mostly of?
iron and nickel, with some lighter elements like oxygen and sulfur. This composition is inferred from studying seismic waves and the behavior of materials under high pressure and temperature conditions similar to those found in the Earth's core.
What pieces of evidence supports the theory that the Earth's interior is composed of different elements than those prominent in the crust?
The study of seismic wave behavior provides evidence that the Earth's interior is composed of different elements than the crust. These waves change speed and reflect differently at boundaries between different layers, indicating varying compositions. Additionally, analysis of meteorites and volcanic eruptions has revealed elements that are not abundant in the Earth's crust but are present in the mantle and core.
How do scientists know that the inner core is solid?
Scientists use seismic waves from earthquakes to study the Earth's interior. By analyzing the way these waves travel through the Earth, they have found that certain waves cannot pass through the inner core, indicating that it is solid. Additionally, laboratory experiments that simulate the high pressure and temperature conditions in the Earth's core support the idea that the inner core is solid.
What was a goal of the industrial workers of the world in 1905?
Get rid of the differences between those who owned property and those who did not. - Apex
What is seismic in earthquakes?
It relates to earthquakes or other tremors in the earth, such as those caused by large explosions

Is earth or venus closer to the earth?
. . the closest between those two choices is . . . Earth.
What is the differences between web browser and a search engine?
There is not really a diffrents between those because there the same thing
How do the energy differences between higher energy levels of an atom compare with the energy differences between the lower energy levels of an atom?
They are smaller in magnitude than those between lower energy levels.
What are the biggest differences between cats and dogs?
probably their size and how much they eat. It depends from animal to animal but those are probably the biggest differences.

What was one of the major differences between the resources available in the Americas and those in Asia and the Mediterranean?
the location
The speed at which seismic waves travel through Earth's layers depends upon the of those layers. temperature density shape area?
The speed of the waves depends on the density of the material.
