Why is the inner core solid and the outer core liquid quizlet?
The Earth's Inner core is solid because there is so much pressure exerted that it can only exist in the solid form. The outer core is liquid iron and nickel. Again, it is very dense but because it is in its liquid form it is less dense than solid and forms the outer core. The outermost layer.
Why is it that outer core is liquid?
Although having a composition similar to Earth's solid inner core, the outer core remains liquid as there is not enough pressure to keep it in a solid state.
Why is the inner core solid?
However, unlike the outer core, the inner core is not liquid or even molten. The inner core's intense pressure—the entire rest of the planet and its atmosphere—prevents the iron from melting. The pressure and density are simply too great for the iron atoms to move into a liquid state.
Why is the outer core liquid quizlet?
The outer core is a liquid instead of a solid Because it is not under as much pressure as the inner core.
Why the inner core is in the solid state?
The inner core is solid because it is made of very dense, or heavy, materials – like iron and nickel. Even though it is very hot, these materials don't "melt" very easily, so they stay solid. Answer 3: It turns out that many materials can be a solid at a higher temperature if the pressure is also higher.
Is the inner core a solid or a liquid?
solid The core of the Earth is made up mainly of iron, in an outer liquid layer and an inner solid layer. The outer core is where the circulating conducting liquid generates the geodynamo, responsible for our magnetic field.
Is the outer core liquid or solid?
The outer core is the third layer of the Earth. It is the only liquid layer, and is mainly made up of the metals iron and nickel, as well as small amounts of other substances. The outer core is responsible for Earth's magnetic field.
Which layer of Earth is a liquid and why?
The outer core is the liquid largely iron layer of the earth that lies below the mantle. Geologists have confirmed that the outer core is liquid due to seismic surveys of Earth's interior. The outer core is 2,300 km thick and goes down to approximately 3,400 km into the earth.
What do you think is reason why the outer core is liquid while the inner core remains solid Brainly?
However, the PRESSURE on the inner core is greater than the pressure on the outer core and the melting point of iron, the main constituent of the core, INCREASES as the pressure goes up. So, because the pressure effect overrides the temperature effect, the inner core is solidified.
Why is the inner core is solid?
However, unlike the outer core, the inner core is not liquid or even molten. The inner core's intense pressure—the entire rest of the planet and its atmosphere—prevents the iron from melting. The pressure and density are simply too great for the iron atoms to move into a liquid state.
How do we know the outer core is liquid?
Two kinds of waves created by earthquakes are compressional (P) waves and shear (S) waves. Both of these waves can travel through solids, but S waves cannot travel through liquids. Scientists figured out that the outer core must be liquid because S waves do not pass through it, but P waves do.
Why is the inner core a solid?
However, unlike the outer core, the inner core is not liquid or even molten. The inner core's intense pressure—the entire rest of the planet and its atmosphere—prevents the iron from melting. The pressure and density are simply too great for the iron atoms to move into a liquid state.
Is the inner core solid liquid or gas What keeps it in this place?
The Earth's inner core is a solid sphere of iron and a little nickel. It is easily hot enough to be a liquid; in fact, the average temperature in the inner core is about 11,100° F (6150° C.) However, the immense pressure on top of it keeps it squeezed into a solid.
Is the inner core solid or liquid?
solid The core of the Earth is made up mainly of iron, in an outer liquid layer and an inner solid layer. The outer core is where the circulating conducting liquid generates the geodynamo, responsible for our magnetic field.
Is the outer core a solid or liquid?
Cite. The core of the Earth is made up mainly of iron, in an outer liquid layer and an inner solid layer. The outer core is where the circulating conducting liquid generates the geodynamo, responsible for our magnetic field.
Is the inner core of the Earth solid or liquid?
Newswise — Earth's core, the deepest part of our planet, is characterized by extremely high pressure and temperature. It is composed of a liquid outer core and solid inner core. The inner core is formed and grows due to the solidification of liquid iron at the inner core boundary.
Why is inner core liquid?
The inner core's intense pressure—the entire rest of the planet and its atmosphere—prevents the iron from melting. The pressure and density are simply too great for the iron atoms to move into a liquid state.
Why does the inner core is solid?
However, unlike the outer core, the inner core is not liquid or even molten. The inner core's intense pressure—the entire rest of the planet and its atmosphere—prevents the iron from melting. The pressure and density are simply too great for the iron atoms to move into a liquid state.
Is the outer core a liquid or solid?
Obviously because the inner core is solid but the outer core is liquid, we must conclude that the drop in temperature vs the drop in pressure must be lower than the gradient of 16 degrees/GPa shown in the diagram below (link to source), given that at the outer-core temperature has exceeded the melting point of iron/ …
