What else can I help you with?
How do P and S waves prove that the outer core is a liquid?
Unlike the P-wave, the S-waves, or shear waves, cannot travel through liquids, and this causes a shadow zone for S-waves opposite to where they originate(caused by the molten outer core of the Earth).
What happens when s waves hit the outer core of earth?
S-waves cannot travel through the liquid outer core because it cannot support shear stress. Instead, they are either absorbed or reflected when they reach the outer core boundary, causing a shadow zone on the opposite side of the Earth from the earthquake where these waves are not detected.
What type of earthquake waves can not pass through the earths inner core?
S waves (secondary waves) cannot pass through Earth's inner core because it is liquid. S waves travel by shearing the rock, which is not possible in a liquid medium. Only P waves (primary waves) can pass through the inner core because they can travel through both solid and liquid material.
Which type of seismic wave cannot travel through the core?
S-Waves, or shear waves cannot travel through the liquid outer core because liquids have no shear and therefore shear waves cannot propagate through them http://en.wikipedia.org/wiki/S-wave
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 type of scientist analyzes the composition of rocks?
A geologist does that and he/she studies both the liquid and solid materials of earth.
Which structural layer of earths interior have scientists concluded is liquid?
the mantle
Who concluded that rockets for space flight must be powered by liquid fuel?
Germany
What is our risk level from convection currents?
Convection currents are caused by a rising temperature of liquid in the earth's mantle. The risk is that the pressure will build up and, through volcanoes, the liquid will be pushed out. The risk level varies from place to place and is carefully monitored by geologists.
Why do geologists consider the inner core and the outer core as parts of the same layer instead of two separate layers?
because the outer core is liquid and the inner core is solid.
How do geologists know that the earth is not just filled with magma?
Geologists use seismic waves from earthquakes to study the interior of the Earth. These waves behave differently as they pass through solid and liquid materials, allowing geologists to determine that the Earth has distinct layers of solid rock and a liquid outer core, rather than being entirely filled with magma. Additionally, the study of volcanoes and magma that reaches the surface provides further evidence that the Earth's interior is not entirely molten.
What do longitudinal waves have to do with earthquakes?
The disturbance from an earthquake propagates as a wave. This wave can be either longitudinal or transverse. (Since waves that pass through the Earth's core are always longitudinal, geologists conclude that the Earth is liquid. A liquid won't transport transverse waves.)
Why can you drink through a straw?
because there is a gap throgh it therefore liquid can pass through it (:
What state of matter must be supplied with the most energy to turn it into a gas And why?
Solid, because it goes through a longer process than the Liquid. Thus, the Liquid doesn't need as much energy as a solid.
Can you intake more liquid through one straw or through two straws?
You get more water in 1 straw then you get out of 2 straw because when you have 2 straws you just get more air then water.
What is the change from liquid to gas?
To change a gas to a liquid, you condense it.
What is the change to gas to liquid?
through a process called evaporation, when the liquid is turned into a gas because something like heat
