D.
P waves move matter up and down, perpendicular to the direction of the wave, while S waves move matter back and forth, in a direction parallel to the direction of the wave.
Answers
Answer:
C. P waves move matter back and forth, in a direction parallel to the direction of the wave, while S waves move matter up and down, perpendicular to the direction of the wave.
Explanation:
P and S - waves are both called seismic waves. They are produced during deformation within the earth.
Usually, P or Primary waves have the fastest velocity and arrives at the seismic station first. Secondary, Shear or S-waves follows P-waves.
P-waves are body waves that propagates within a body. They cause movement internally. Secondary waves are surface waves. They move on the surface of earth. One way to also distinguish between these two seismic waves is that, P-waves are longitudinal waves that travels parallel or longitudinally to the source. Secondary waves moves in an up and down motion pattern. They propagate transversely to their source.Related Questions
What would be the greatest threat to LA if a magnitude 8 earthquake struck along the San Andreas Fault?
A. Buildings toppling over
B. Tsunami
C. Fires from downed power lines
D. Giant fissures opening up
Answers
The greatest threat to LA if a magnitude 8 earthquake struck along the San Andreas Fault would be fires from downed power lines.
Why is it the greatest threat?
The San Andreas Fault is an active geological formation in the state of California, and earthquakes are common in the area. The 1994 Northridge earthquake, which killed at least 57 people, damaged buildings, and resulted in a power outage for more than 200,000 residents, was one of the most recent and devastating quakes to strike the Los Angeles area.
When a powerful earthquake strikes an area, it can cause a range of devastating effects, including buildings toppling over, tsunami, fires from downed power lines, giant fissures opening up, and so on. However, based on the history of earthquakes in the Los Angeles area, it is known that fires from downed power lines are the most common danger following an earthquake, with the potential to cause more destruction than the earthquake itself.
Therefore, the greatest threat to LA if a magnitude 8 earthquake struck along the San Andreas Fault would be fires from downed power lines.

If a magnitude 8 earthquake were to strike along the San Andreas Fault, the greatest threat to LA would be buildings toppling over and fires from downed power lines. This is because of the highly dense population of Los Angeles and the age of many of the buildings.
The San Andreas Fault is a fault zone in California that forms the tectonic boundary between the Pacific Plate and the North American Plate. It's roughly 800 miles long and stretches northwestward from the Gulf of California through western California, across the Pacific Ocean floor, and into the Aleutian Islands. It passes through two of the most populated regions in California, Los Angeles and San Francisco. The greatest threat to Los Angeles is buildings toppling over and fires from downed power lines in the event of a magnitude 8 earthquake striking along the San Andreas Fault. This is due to the high population density of Los Angeles and the age of many of its buildings. Buildings in Los Angeles are predominantly made of concrete and brick, making them more susceptible to damage in the event of an earthquake. In addition, because of the age of the buildings in the area, many do not meet modern building codes for earthquake safety, which can exacerbate the damage caused by an earthquake. Fires from downed power lines are another major concern in the aftermath of an earthquake. The shaking caused by an earthquake can cause power lines to come down, which can then ignite fires if they come into contact with combustible materials. This is a significant danger in urban areas like Los Angeles, where there are many sources of fuel for fires, such as gas stations, and where emergency services may have difficulty responding to the fires due to damage to roads and other infrastructure.

____ facies are expected at the core of mountains formed at a continental-continental convergent plate boundary.
Answers
Answer:
Granulite.
Explanation:
A granulite can be defined as a set of cluster of metamorphic rock formulated by the process of metamorphism. Under this process of metamorphism, a granulite is essentially fashioned with or without quartz. A granulite facies are composed under the experience of high pressure/high temperature, which can be found at the core of continental crust.
Near the core of continental crust, the biotite mineral breaks down when under the high-temperature and forms the granulite facies from the composition of orthopyroxene, feldspar, and water.
Therefore, the correct answer is granulite facies.

what subdivision of the geologic time scale represents the greatest expanse of time?
Answers
The subdivision of the geologic time scale that represents the greatest expanse of time is called "Precambrian".
The greatest expanse of time in the geologic time scale is represented by the Eon. Eons are the largest subdivision of time and encompass billions of years. The geologic time scale is divided into four eons: the Hadean, Archean, Proterozoic, and Phanerozoic.
The Phanerozoic Eon, which began approximately 541 million years ago and continues to the present day, represents the most recent and significant portion of Earth's history. It is further divided into three eras: the Paleozoic, Mesozoic, and Cenozoic.
While the Phanerozoic Eon is the most recent and well-known due to its relevance to the evolution of life on Earth, it still represents only a fraction of the total geologic time scale. The preceding eons, Hadean, Archean, and Proterozoic, span vast periods of time.

why does the eclipse seem to travel from one place to another?
Answers
The moon also seems to orbit Earth in a counterclockwise direction when seen from this point in space. The total solar eclipse's shadow moves across the surface of Earth from west to east due to the moon's circular motion.
The orbit of the Moon, our planet's natural satellite, is well recognized. When the Moon passes between the Sun and the Earth throughout its recurring cycle, it prevents the Sun's light from reaching the planet.
The planet is then covered in a thick shadow. But during a total solar eclipse, we can observe the Moon's actual motion as it moves from west to east across the face of the Sun.

as the length of the confidence interval for the population mean increases, the degree of confidence in the interval's actually containing the population mean
Answers
When the length of a confidence interval increases, the degree of confidence in its actually containing the population parameter being estimated increases.
What relationship exists between the size of the population mean increase confidence interval and the level of interval confidence?The probability that a confidence interval truly contains the population parameter being assessed rises as its length does. The width of the confidence interval for a population mean shrinks with the sample size at a fixed level of confidence. A population parameter's point estimate is thus always in the middle of the parameter's confidence interval.
The relevant sample statistic is the most accurate point estimate for a population parameter. When determining confidence intervals for the difference between two population proportions using equal sample sizes, the sample size will grow when the margin of error is decreased and the significance level is held fixed.
