As P and S waves move further into the Earth's mantle, their speed rises. They are responsible for causing earthquakes.
They follow curving trajectories through the Earth, but as they cross the dividing line between substances in various states, they abruptly reverse course.
P waves leave the earthquake first and go the furthest. Rock oscillates perpendicular to the direction of wave propagation in S or shear waves. In rock, S waves typically move at a pace of roughly 60% that of P waves, and they always come after the latter.
As compressional waves are also known as P-Waves (P stands for "primary"). Shear waves are sometimes known as secondary waves since they travel through the Earth's atmosphere more slowly than compressional waves and arrive after them.

Why is continental crust less dense than oceanic?
Granitic rocks, which have even more silicon and aluminum than the basaltic oceanic crust and are less dense than basalt, make up the continental crust.
Although continental rocks are very diverse, the upper continental crust is accessible and has been thoroughly sampled. According to estimates, the average composition above 30 km is approximately 67 wt% silica and hasn't changed significantly in about 50 years.
For more information, see the tables in Yanagi (2011) and Henderson (1982). Many of these estimations are based on grids of rock samples collected from numerous sizable regions of the world.
The lower continental crust's composition is still poorly constrained because the deepest drill hole in the world—the 12 km borehole in Kola—did not extend there. The entirety of the continents is thought to be represented by andesite (57 weight percent silica).

how is parallax used to measure the distances to stars
Parallax is a method used to measure distances to nearby stars. It takes advantage of the fact that as the Earth orbits the Sun, the position of nearby stars as seen from the Earth appears to change.
Here's how it works: Observation at two different points in Earth's orbit: The first observation is taken when the Earth is on one side of its orbit around the Sun. Six months later, a second observation is taken when the Earth is on the opposite side of its orbit.
Triangulation: These two observations form a triangle with the star at one vertex and the two positions of the Earth at the other two vertices. The size of this triangle can be used to determine the distance to the star.

how does the phosphorous get released from the rock?
By rain and weathering the phosphorous get released from the rock . Phosphorus cycles through rocks, water, soil and sediments, and organisms.
Phosphorus is found in the earth's crust, mainly in sedimentary rocks containing phosphate minerals, As these rocks are weathered and eroded, dissolved phosphates enter the soil and travel to the ocean via rivers. Over time, phosphate ions and other minerals form in rocks due to rain and weathering. This inorganic phosphate is then distributed into soil and water.
Since the main source of phosphorus is in rocks, the first step in the phosphorus cycle involves the removal of phosphorus from rocks by weathering. Weather conditions such as rain and other sources of erosion cause phosphorus to leach into the soil.

which combination of magma viscosity and gas content is most likely to lead to explosive volcanic eruptions?
The combination of magma viscosity and gas content is more likely to lead to explosive volcanic eruptions depending on the high amount of magma and gas.
How do explosive volcanic eruptions occur?When the magma is very viscous and there is a lot of gas, it is stored under the volcanic surface, generating an increase in pressure that leads to violent eruptions.
Therefore, the higher the viscosity of the volcanic magma and the greater the amount of gas, the more likely the volcano will be susceptible to eruptions due to the difficulty of escaping the gases, which increases the pressure that overcomes the resistance of the volcanic rocks.

Livelihood: Livestock farming provides employment and income for millions of people in Pakistan, particularly in rural areas. It is a major source of income for small-scale farmers, who can sell milk, meat, and other animal products to local markets or larger companies.
Food security: Livestock farming contributes significantly to food security in Pakistan by providing a source of protein-rich food to the population. It is estimated that more than 80% of the rural population in Pakistan rely on livestock for food and income.
Agricultural productivity: Livestock farming also contributes to agricultural productivity by providing manure and other organic materials that can be used as fertilizers. This helps to improve soil fertility and crop yields, particularly in areas where chemical fertilizers are not easily available or affordable.
Export potential: Pakistan has a growing export market for livestock and livestock products, including beef, mutton, and dairy products. Livestock farming can help to boost the country's export earnings and reduce its trade deficit.
Climate resilience: Livestock farming can be an important source of income for farmers during periods of drought or other climate-related shocks. It is often more resilient than crop farming, as animals can survive on lower-quality feed and can be sold or traded in times of hardship.
Overall, livestock farming plays an important role in the economy and society of Pakistan, and has the potential to contribute to sustainable development and poverty reduction in the country.

A geological principle known as uniformitarianism asserts that throughout the history of the Earth, the same natural processes that exist today have always functioned in the same way.
According to uniformitarianism, the geological features we can currently observe, such as mountains, valleys, and rivers, were developed over a long period of time by slow, progressive processes rather than by sudden catastrophic catastrophes. James Hutton, a Scottish geologist, made the initial argument for uniformitarianism in the late 18th century. He claimed that by examining the current processes that create the planet, one may learn about the Earth's geological history.
Since it was originally put forward, the uniformitarianism principle has been a cornerstone idea in geology, and it has greatly influenced how we view the Earth's past and the processes that have shaped its surface over millions of years.

at the 1997 rate of consumption, about how long will the estimated 2,000 billion barrels of oil last?
Estimating the exact duration of the world's remaining oil reserves is a complex task that depends on various factors such as the rate of consumption, discoveries of new oil reserves, technological advancements in oil extraction, and changes in global demand.
However, based on the 1997 rate of consumption, I can provide a rough estimate.
In 1997, the world consumed approximately 75 million barrels of oil per day, so the 2,000 billion barrels of oil would last approximately 26.3 years. However, it's important to note that this is just an estimate, and the actual duration could be significantly different due to changes in the factors mentioned above.
Furthermore, it's also worth mentioning that the world's oil reserves are not distributed evenly, and some countries have much larger reserves than others.

What were a section in a canal used to raise water and boats
A section in a canal used to raise water and boats is known as a lock. A lock is a device that is used to transfer boats and ships between different water levels in a canal system.
A canal lock consists of a chamber that can be filled or emptied of water to adjust the water level inside, which is typically surrounded by walls or gates. To raise a boat or ship to a higher level, the water inside the lock is emptied, and the boat is allowed to float into the lock chamber. Once the boat is inside the lock, the gate behind it is closed, and the gate at the other end is opened. The lock is then filled with water from the higher level, which lifts the boat to that level. To lower a boat to a lower level, the process is reversed, with the water inside the lock being let out and the boat floating down to the lower level.
Locks are essential for maintaining the water levels in a canal system, allowing boats to traverse areas with changes in elevation, such as hills and valleys.

two tectonic plates pushing toward each other cause intense heat and pressure in earth’s crust. into which will crust material be changed by heat and pressure?
When two tectonic plates push towards each other, the boundary between them is called a convergent boundary.
At this boundary, one plate is forced under the other, causing intense heat and pressure in the Earth's crust. This heat and pressure can cause changes in the crustal material, leading to the formation of new rock types. In particular, sedimentary rocks that are made up of layers of sand, mud, and other materials can be transformed into metamorphic rocks under heat and pressure. This transformation occurs through the process of metamorphism, where the minerals in the sedimentary rocks recrystallize and reorganize under the influence of high temperature and pressure, resulting in new rock types.
