Seismic waves traveling through the inner core go faster than those through the outer core.

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.

How do scientistS know that the earth's inner core is made of dense iron and it's outer core is liquid?
Scientists use seismic waves from earthquakes to study the Earth's interior. By analyzing the speed and behavior of these waves as they travel through the Earth, scientists can infer the composition of the layers. For the Earth's inner core being dense iron and the outer core being liquid, this is supported by the behavior of seismic waves, which show that the inner core is solid due to shear waves not passing through it, while the outer core must be liquid to allow the transmission of seismic waves.
What is earths internal composition?
nope i dont know really
What is hotter inner mantle or outer mantle?
The inner mantle is hotter than the outer mantle. Temperatures in the inner mantle can reach up to 4,000 degrees Celsius, whereas temperatures in the outer mantle range from about 500 to 900 degrees Celsius.
Which is used by scientists as evidence that earths inner core is soild?
Scientists use seismic waves and their behavior as they pass through the Earth's inner core to provide evidence that it is solid. The way these waves travel, reflect, and refract within the inner core suggests it is composed of solid iron and nickel. Additionally, studies on how seismic waves travel through the Earth and the speed at which they travel further support the solid nature of the inner core.
Inner core thickness?
The inner core of the Earth is a solid iron-nickel alloy with a radius of about 1220 kilometers. It is the densest layer of the Earth and produces the planet's magnetic field through the movement of molten iron in the outer core. The inner core is believed to have formed as a result of solidification of the outer core due to decreasing temperatures and increasing pressure.
What evidence did scientists use to figure out Earths inner core is solid?
Scientists use the difference in density between the inner and outer core as evidence that the inner core is solid. This was proven using seismic waves traveling through the earth.

What happens in the inner core?
The inner core is solid and made up primarily of iron and nickel. It is the hottest part of the Earth, with temperatures reaching up to 5700°C. The immense pressure at the center of the Earth keeps the inner core solid despite its high temperature.
What types of gases are on the inner core?
The inner core of the Earth is primarily composed of solid iron and nickel. It is a solid metallic sphere rather than a gaseous one, as the intense pressure and high temperatures prevent the presence of gases in this region.
Does the liquid in the inner core or outer core flow in currents?
The liquid in the outer core flows in currents due to the Earth's rotation and convective motion generated by heat from the inner core. The inner core, being solid, does not flow in the same way as the liquid outer core.
Why is the inner core a solid?
Dont know exactly i know that heat gives a substance more energy if that helps any.the pressure from everything around it causes it to compress into a solid. >
Which planet has a large solid core?
Earth is the planet with a large solid core consisting mainly of iron and nickel. This core is divided into a solid inner core and a liquid outer core, which is responsible for generating the Earth's magnetic field.
How many layers does earth have and what are the names?
Earth has four main layers: the inner core, outer core, mantle, and crust. The inner core is solid iron and nickel, the outer core is liquid iron and nickel, the mantle is mostly solid rock, and the crust is the Earth's outermost layer where we live.

What evidence did scientists use to figure out that earth inner core is solid rock?
They do not have evidence. In fact most pf things are not even true. The only thing they say they did was put a stick on the ground and with a shockwave they knew what was inside the earth. My opinion is that the core is not what scientists say it is. Due to the fact that we know more about the moon than our own planet.
What is hotter inner mantle or outer mantle?
The inner mantle is hotter than the outer mantle. Temperatures in the inner mantle can reach up to 4,000 degrees Celsius, whereas temperatures in the outer mantle range from about 500 to 900 degrees Celsius.
