The waves are refracted as they travel through the Earth
due to a change in density of the medium
. This causes the waves to travel in curved paths. When the waves cross the boundary between two different layers, there is a sudden change in direction due to refraction.
Which wave can travel through the Earth’s core?
2. P-waves speed up again through the inner core and
S-waves
also travel through it, suggesting that the inner core is composed of solid iron and nickel. 3. Figure 19.10: The increase of temperature with depth in the earth is indicated by a curve called the geotherm.
Can surface waves travel through the core?
Body waves can travel through the Earth’s inner layers, but
surface waves can only move along the surface of the planet
like ripples on water.
Can pass through the core Cannot pass through the core?
Secondary waves are a type of seismic waves. They can travel through solid medium only. The outer core is made up of liquid state. Hence,
secondary waves cannot pass through outer core
.
Which type of seismic wave Cannot pass through Earth’s core What does that indicate about the composition of the core?
P waves can travel through Earth’s outer core, but
S waves
cannot. Because of this, scientists know 16. Scientists use the properties of seismic waves to figure out the structure of Earth’s interior. For example, seismic waves travel faster through denser layers than through less dense layers.
Which type of wave can penetrate the outer core and the inner core?
P waves
penetrate the core.
Which seismic wave can penetrate core but refracts?
10. Which seismic wave can penetrate the core but refracts?
P waves
also refracts but is able to penetrate the core.
Which seismic wave Cannot penetrate core?
The seismic waves that get refracted and cannot pass through the core of the Earth are:
S-waves
.
Can S-waves travel through the interior of the Earth?
S-waves (S stands for secondary) are shear earthquake waves that
pass through the interior of the Earth
.
How is outer core different from the inner core?
The inner core and the outer core are made up of similar stuff chemically (both are made mostly of iron, with a little nickel and some other chemical elements)–the difference between them is that
the outer core is liquid and the inner core is solid
.
Which waves Cannot pass through the core?
S waves
cannot pass through the liquid outer core, but P waves can. The waves are refracted as they travel through the Earth due to a change in density of the medium.
Which waves Cannot pass through outer core right or wrong?
Answer: The secondary waves of earthquake can travel only through the solid state in the interior of the earth. Since the outer core of the center of the earth is in liquid state, the secondary waves are not able to travel through the outer core of the earth.
What is the phase of matter of Earth’s outer core?
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.
Which type of seismic wave Cannot pass through Earth’s core What does that indicate about the composition of the core quizlet?
S-waves
, a type of seismic wave, cannot travel through liquids. They do not pass through the Earth’s outer core, so the outer core is made of what? What sort of material is the mantle? The boundary between two dissimilar materials.
Why is the outer core a liquid but not the inner core?
Inner core – High pressure from the other layers at the Earth center makes the inner core solid. Outer core – It is liquid
because the temperature is high and there is not enough pressure to make it solid
.
What element makes up most of Earth’s core?
Unlike the mineral-rich crust and mantle, the core is made almost entirely of metal—specifically,
iron and nickel
. The shorthand used for the core’s iron-nickel alloys is simply the elements’ chemical symbols—NiFe. Elements that dissolve in iron, called siderophiles, are also found in the core.
What happens to P-waves and S-waves as they travel inside the earth?
P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation.
In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave
.
Which seismic waves stay on Earth’s surface?
There are two major kinds of surface waves:
Love waves
, which are shear waves trapped near the surface, and Rayleigh waves, which have rock particle motions that are very similar to the motions of water particles in ocean waves.
