When there is an earthquake, seismic waves are created. Seismic waves are energy traveling through air, water, or rock. There are a few different types of seismic waves but the one in question here are called body seismic waves. These body waves can only travel through solids or rock.
So we can measure a body wave created from an earthquake or atomic bomb on one part of the planet and measure it on a different part of the planet. So if Earth is solid to the core we should be able to measure the same seismic body wave on opposite sides of the planet, but we can't, the wave generated on one side of the planet isn't transmitted to the exact opposite side. This is because of the liquid layer of the earth. Once the body wave hits the liquid layer it is quickly dissipated.
What else can I help you with?
What is one way that scientists know the outer core is liquid?
Scientists know the outer core is liquid because S waves, which cannot travel through liquid, are not detected beyond the core. Additionally, seismic waves from earthquakes have shown that P waves slow down significantly when passing through the outer core, indicating it is a liquid layer.
How do scientistS know that the earth's inner core is made of dense iron and it's outer core is liquid?
When eartquakes erupt only certaing wavelengths can travel through both liquids and solids, so when the scientists measure to see at what point in the earth the waves refract they can then tell what parts are solid and what parts are liquid
What is the outer core made of liquid or solid?
Melted iron and nickel alloy. It is too hot near the centre, so it is liquid. But if you want to know if the inner core is solid or liquid, then it is solid, because there is too much pressure from the rest of the Earth
How do you know how big the inner core outer core and mantle are?
The sizes of Earth's inner core, outer core, and mantle are determined through seismic studies, which analyze how seismic waves travel through the different layers of the Earth. Scientists study the speed of seismic waves and how they bend or refract as they travel through the Earth to determine the size and composition of these layers.
What is internal composition of Earth?
The Earth is composed of four main layers: the inner core, outer core, mantle, and crust. The inner core is solid iron and nickel, surrounded by a liquid outer core of the same materials. The mantle is composed of molten rock, while the crust is a thin, solid layer that forms the Earth's surface.
What is one way that scientists know the outer core is liquid?
Scientists know the outer core is liquid because S waves, which cannot travel through liquid, are not detected beyond the core. Additionally, seismic waves from earthquakes have shown that P waves slow down significantly when passing through the outer core, indicating it is a liquid layer.
What is one way the scientists know the outer core is liquid?
some kinds of seismic waves cannot travel through liquids, such as the outer core.
How do you know the earth has a liquid outer core?
Seismic measurements and rheology. The outer core is so hot the iron and nickel there is liquid. The inner core is also as hot and just as liquid but the pressure in the inner core is so great it is solid. Some believe the inner core is a single iron crystal from earth's initial formation but there is no evidence to support that.
How did the scientist to know the outer core is liquid?
Scientists determined that the Earth's outer core is liquid primarily through the study of seismic waves generated by earthquakes. When these waves travel through the Earth, they behave differently depending on the state of the material they encounter. S-waves, which cannot travel through liquids, are absent in the outer core, indicating that it must be in a liquid state. Additionally, the behavior of P-waves, which can travel through both solids and liquids, further supports the conclusion that the outer core is liquid.

How do you know earths outer core is liquid?
Volcanoes allow the molten lava from the outer core to pass through weak spots in the mantle.
How do we know the outer core is liquid?
seismic waves travel slowly trough
What is one way scientist know the outer core is liquid?
some kinds of seismic waves cannot travel through liquids, such as the outer core.
Does the liquid in the inner core or outer core flow in currents?
The inner core is solid, but the mantle is the only layer of Earth that flows in currents. These currents are caused by convection. If you don't know what convection is then you might as well look it up because I don't have a good definition.
Why are seismologist important?
They are important because they study p-waves and s-waves which now we know that the Outer Core is liquid
What is the outer core made of liquid or solid?
Melted iron and nickel alloy. It is too hot near the centre, so it is liquid. But if you want to know if the inner core is solid or liquid, then it is solid, because there is too much pressure from the rest of the Earth
How do you know What is inside the Earths core?
Scientists study seismic waves and magnetic fields to determine the composition and properties of Earth's core. They use data from earthquakes and magnetic measurements to infer that the inner core is solid iron and nickel, while the outer core is liquid iron-nickel alloy. Deep drilling and experimental simulations also provide insights into the Earth's core composition.
