What happens to the size of the shadow zone as the diameter of the liquid core increases?
As the diameter of the liquid core increases, the size of the shadow zone decreases. This is because the larger diameter allows for more refraction of seismic waves, leading to less complete shadowing of seismic waves at certain distances.
Why does an earthquake get weaker as you move further away from the epicentre?
An earthquake gets weaker as you move away from the epicenter because the seismic waves spread out in all directions, losing energy as they travel through the Earth's layers. The farther you are from the epicenter, the more the energy of the seismic waves is spread out over a larger area, resulting in weaker shaking.
How much bigger is a magnitude 9.7 earthquake than a 6.8 earthquake?
A magnitude 9.7 earthquake is significantly larger than a 6.8 earthquake. The difference in magnitude signifies a 10^3.7 times increase in amplitude of seismic waves released, resulting in much greater energy and destructive power.
What happens to the energy when sunlight hits earth at an angle smaller than ninety degrees?
When sunlight hits Earth at an angle smaller than ninety degrees, the energy is spread over a larger surface area, resulting in less energy per unit area. This leads to lower intensity of sunlight and reduced heating compared to when sunlight hits directly overhead.
How would the seismograph for the two earthquake compare?
The seismograph for a larger earthquake would show stronger and more prolonged seismic waves compared to a smaller earthquake. The amplitude and duration of the seismic waves recorded by the seismograph would be greater for the larger earthquake.
What happens when a seismic wave grows increasingly larger?
The seismic wave's energy get's a-lot smaller
What happens to the energy in a seismic wave as the wave grows larger?
As a seismic wave grows larger, the energy it carries remains constant. The amplitude (height) of the wave increases, but the total energy the wave carries does not change. The energy is redistributed within the wave to accommodate the larger amplitude.
What happens to the energy to seismic waves at the distance from the focus increase?
As the distance from the seismic wave's focus increases, the energy of the seismic waves dissipates and spreads out over a larger area. This results in a decrease in wave amplitude and intensity as they travel through the Earth's crust. Consequently, the seismic waves become weaker, leading to a reduction in the perceived shaking and damage at greater distances from the epicenter.
How geometrical spreading affects the seismic waves?
Geometrical spreading refers to the way seismic waves distribute their energy as they propagate through the Earth. As waves travel outward from a point source, their energy spreads over an increasingly larger area, resulting in a decrease in amplitude and intensity with distance. This phenomenon affects the observed seismic wave characteristics, such as their amplitude and frequency, leading to weaker signals at greater distances from the source. Consequently, geometrical spreading is a crucial factor in seismic wave analysis and interpretation in seismology.
What makes waves small?
Very small seismic activity causes small waves to occur. The bigger the waves get the larger the seismic activity is.
What happens to the size of the shadow zone as the diameter of the liquid core increases?
As the diameter of the liquid core increases, the size of the shadow zone decreases. This is because the larger diameter allows for more refraction of seismic waves, leading to less complete shadowing of seismic waves at certain distances.
Why does an earthquake get weaker as you move further away from the epicentre?
An earthquake gets weaker as you move away from the epicenter because the seismic waves spread out in all directions, losing energy as they travel through the Earth's layers. The farther you are from the epicenter, the more the energy of the seismic waves is spread out over a larger area, resulting in weaker shaking.
What does increasingly mean?
Meaning: Advancing in amount or intensity Synonyms: increasingly; more and more; progressively Context example: she became increasingly depressed Pertainym: increasing (becoming greater or larger) By: MMC
Does a primary seismic wave have a larger shadow zone than a secondary wave?
no, an s-wave shadow zone is way larger
What kind of scale used to measure the amount of seismic energy realized by an earthquake?
The Richter scale is commonly used to measure the amount of seismic energy released by an earthquake. It quantifies the magnitude of an earthquake based on the amplitude of seismic waves recorded by seismographs. More recently, the Moment Magnitude Scale (Mw) has become the standard for measuring larger earthquakes, as it provides a more accurate representation of their size by considering the fault area and the amount of slip. Both scales help in assessing the potential impact and damage caused by earthquakes.
What kind of scal used to measure the amount of seismic energy released by an earthquake?
The Richter scale is commonly used to measure the amount of seismic energy released by an earthquake. It quantifies the magnitude of an earthquake based on the amplitude of seismic waves recorded by seismographs. Another scale, the Moment Magnitude Scale (Mw), is often used for larger earthquakes, providing a more accurate measure by considering factors like the fault area and the amount of slip. Both scales help in understanding the potential impact of an earthquake.
What happens to the amplitude of a wave if more energy is added?
The amplitude of a wave increases as more energy is added to it. This means that the displacement of the particles or the height of the wave increases, resulting in a larger motion.
