Draw three diagrams to show how each type of seismic wave moves through rocks?
Seismic waves are primarily categorized into three types: P-waves, S-waves, and surface waves. P-waves (primary waves) are compressional waves that move back and forth in the same direction as the wave, causing particles in the rock to compress and expand. S-waves (secondary waves) move perpendicular to the direction of wave travel, causing particles to move side to side, which results in shear stress in the rocks. Surface waves travel along the Earth's surface, causing both vertical and horizontal ground movement, similar to ocean waves, which often leads to the most damage during an earthquake.
How does the speed of the seismic waves change as they travel farther and farther from the epicenter?
As seismic waves travel farther from the epicenter, their speed generally remains consistent, determined by the type of wave and the properties of the Earth's materials they pass through. However, the amplitude of the waves typically decreases with distance due to geometric spreading and energy absorption by the Earth's materials. Surface waves, which typically travel slower than body waves, may show more significant attenuation as they disperse over greater distances. Thus, while the speed is not affected by distance, the energy and intensity of the waves decrease.
How do scientists find out about the inner core of earth?
A seismograph is used to sense seismic waves in the earth. The seismic waves are sent down by scientist and how fast and how straight the line is when the seismograph reads them is how they tell which mineral or if its a liquid or solid. Which is how they know about the inner and outter core, and the mantel.
How seismic studies support seafloor spreading?
Seismic studies show evidence of mid-ocean ridges where new oceanic crust is forming, supporting the theory of seafloor spreading. By analyzing seismic waves, scientists can map the structure of the ocean floor and identify areas of tectonic activity where plates are moving apart. Additionally, seismic data reveals the presence of magnetic striping on the seafloor, further supporting the idea of seafloor spreading.
What part of earths interior layers are in motion due to density differences?
The outer core is liquid and convects. The mantle also convects, although it is almost entirely solid and it is a matter of debate whether the entire mantle convects, or whether there are seperate layers each individually convecting.
What does time-distance graph of seismic waves show?
Comparison of waves going through the solid inner core and those just skimming it can show the rotation of the inner core.
What is the instrument that records earthquakes waves?
A seismograph records earthquake waves.the correct answer is a seismometer a seismograph is the graph to show the recordings
How is seeismic waves measured?
Seismic waves are measured using seismometers, which detect the ground vibrations created by seismic events like earthquakes. Seismometers record the data in the form of seismograms, which show the amplitude and arrival times of different types of seismic waves such as P-waves and S-waves. By analyzing these seismograms, scientists can determine the characteristics of the seismic event and its location.
What ways do seismic waves show us what the interior is like?
very carfully
How can seismic waves be used to determine an earthquake's epicenter?
The epicenr can be found by location the sound in the waves carried.
How to read a seismograph and interpret seismic activity accurately?
To read a seismograph and interpret seismic activity accurately, first, understand that a seismograph records ground motion caused by earthquakes. Look at the seismograph's wavy lines, called seismograms, which show the intensity and duration of seismic waves. Identify the P-waves (primary waves) and S-waves (secondary waves) to determine the earthquake's location and magnitude. Compare the seismogram with data from other seismographs to confirm the earthquake's characteristics.
Is seismic waves indirect or direct evidence?
Seismic waves provide indirect evidence of the Earth's internal structure. They do not directly show us what is inside the Earth but instead allow scientists to infer the properties and composition of different layers based on how these waves travel and behave as they pass through various materials. By analyzing seismic wave patterns, researchers can deduce information about the Earth's core, mantle, and crust.
The shadow zone exists because?
sunlight blocks out S waves in certain regions.
Can you model a typical surface wave on the simulation?
I can simulate various types of surface waves, such as ocean waves or seismic waves, using numerical methods to model their behavior and propagation characteristics. The simulation can show how the wave moves and interacts with different types of surfaces or boundaries.
How a bar graph and a line graph alike?
they both show in crease but a line graph may show decrease
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 does a graph not do?
A graph does not cook your meals when you are hungry! A graph does not show causation.
