What does the shadow zone tell scientists about Earths interior?
that the earth is going to end in 2 days
Why is s wave shadow zone larger than the p wave shadow zone?
In simple terms the shadow zone of the S-wave is larger because of the Earth's liquid outer core. The S-wave cannot travel through the liquid outer core but the P-waves get refracted at the boundary between the mantle and the outer core. This is why the S-wave shadow zone is larger than the P wave shadow zone. P waves are refracted at the liquid outer core of the Earth, while S waves are attenuated or stopped entirely. This allows P waves to go "around" the core and reach locations on the far side of the Earth that are within the shadow of the S waves. -- A P-wave is a longitudinal wave with an alternating stretching and compressing motion in the direction of propagation. An S wave is a transverse wave with a vertical motion perpendicular to the direction of propagation. The shadow zone of a P-wave exists from 105 to 143 degrees (epicentral distance). This is caused by P waves meeting the liquid outer core and being refracted. Part of the P wave is also reflected by the outer core and as a result of the two, a shadow zone exists. The shadow zone of an S-wave exists from 105 to 180 degrees (epicentral distance). S-waves cannot travel through liquids at all so rather than being refracted by the liquid outer core and traveling through it, they are totally reflected, resulting in a shadow zone from 105 to 180 degrees.
What causes a shadow?
Light travels in straight lines. A shadow is caused when light beams hit an object and bounce off, preventing the light beams from passing through and hitting the ground on the other side. So when you, for example stand in the sun and the suns rays hit you, the light reflects off you and goes the other way. so behind you no light falls from the direct rays of the sun, so it is dark. The area around your shadow is where the light is hitting and reflecting, so technically speaking there is shadow under them, which is why we associate the ground with being dark. no light.
The shadow zone separates P waves that have reached the surface through the mantle from P waves that have reached the surface after passing through both the mantle and the core?
true.
Which area of earth is unaffected by both p and s waves?
The Crust of the Earth
When p wave bend while traveling through earth's core what happen when arrive at the shadow zone?
serveral minutes later than expected
When the moon goes through the earths shadow what do you see?
you see a eclipse
What is the moon passing through the earths shadow?
That would be a lunar eclipse.
What event is caused by the moon passing through earths shadow?
An eclipse
What happens durning a lunar eclipse?
The moon darkens because it passes through Earths shadow.
What eclipse passes through the earths shadows?
A lunar eclipse occurs when the full moon passes through the Earth's shadow.
The moon experiences a total lunar eclipse when it passes through the earths shadow?
More specifically, a total lunar eclipse occurs when the moon passes through the umbra, the darker part of the shadow.
What shadow is bigger the Moon's umbra or earths umbra?
definitley the earths
When the earths shadow falls on the moon the shadow caused a?
A lunar eclipse.
Why there is not a lunar eclipse on every full moon day?
because the moon does not orbit directly through the earths shadow, only passes through it occasionally.
What does earths shadow cause?
a lunar eclipse
Why is the moon's shadow clearer than earths?
It is not.
