Sedimentary, igneous, and other metamorphic rocks undergo heat and pressure as a result of burial or contact with intrusive or extrusive igneous rocks, which results in the formation of metamorphic rocks.
What are metamorphic rocks?Metamorphism, the process by which existing rocks are changed into new types of rocks, produces metamorphic rocks. In this process, the rock mainly stays solid, but it progressively recrystallizes to a different texture or mineral makeup. The protolith could be an existing metamorphic rock, an igneous rock, or a sedimentary rock. They are divided into different groups based on their protolith, chemical and mineral composition, and texture. Simply by being buried well below the Earth's surface, where they are exposed to extreme heat and the intense pressure of the rock layers above, they may form. When hot molten rock, known as magma, is injected into the rock formation process locally, metamorphic rock can be produced.

a local gardener puts fertilizer on his plants. the plants are very healthy, but what is a negative effect the fertilizers have on the environment?
Answer:
While fertilizers can be beneficial for plants and help them grow, they can also have negative effects on the environment. One of the main concerns with the use of fertilizers is that they can leach into nearby water sources, such as rivers and streams, and cause an excess of nutrients in the water. This can lead to the growth of harmful algae and other aquatic plants, which can deplete the water of oxygen and kill fish and other aquatic life. Additionally, fertilizers can also release harmful pollutants into the air, such as nitrogen oxides, which can contribute to air pollution and damage the ozone layer. Therefore, it is important to use fertilizers responsibly and follow the instructions on the packaging to avoid any negative effects on the environment.

Barbed wire and windmills brought about the closing of the once-open range.
With the invention of barbed wire, rangelands were enclosed, cattle drives ended, and a new way of moving cattle to emerge markets was introduced.
The success of the ranching industry also created unexpected issues. As more ranchers moved into Texas, the range became crowded. The Grazing pastures could not support the growing number of cattle.
Ranchers tried to keep track of their cattle and separate them from other herds, but this proved to be difficult. Also, farmers moved on to the range after Native Americans were confined to reservations.

To what extent are the factors that caused urbanization in Canada the same as those in the developing world? Explain both similarities and difference’s
Answer:
The factors that caused urbanization in Canada are similar to those in the developing world in some ways, but there are also significant differences. Urbanization is the process by which an increasing proportion of a population lives in cities, and it is driven by a range of economic, social, and environmental factors.
One of the key factors that caused urbanization in Canada and in the developing world is the growth of the economy and the expansion of job opportunities in cities. In Canada, the growth of the industrial sector in the 19th and 20th centuries led to the creation of many new jobs in cities, and this attracted large numbers of people from rural areas and other countries. Similarly, in the developing world, the growth of the manufacturing, service, and technology sectors has created many new jobs in cities, and this has attracted many people from rural areas and other countries.
Another factor that has contributed to urbanization in Canada and in the developing world is the availability of infrastructure and services in cities. In Canada, cities have developed a range of infrastructure and services, such as transportation networks, schools, hospitals, and utilities, which have made them attractive places to live and work. Similarly, in the developing world, cities have invested in infrastructure and services, such as roads, ports, airports, and telecommunications networks, which have made them more attractive to businesses and investors.
However, there are also significant differences between the factors that caused urbanization in Canada and in the developing world. In Canada, urbanization has been largely driven by internal factors, such as the growth of the economy and the availability of infrastructure and services, whereas in the developing world, urbanization has often been driven by external factors, such as migration and colonization.
In addition, the urbanization process in Canada has generally been more gradual and orderly than in the developing world, where urbanization has often been characterized by rapid and uncontrolled growth, leading to problems such as overcrowding, pollution, and inequality.
Overall, the factors that caused urbanization in Canada are similar to those in the developing world in some ways, but there are also significant differences, such as the role of external factors and the pace and pattern of urbanization.

The ocean is cold. Because a storm formed over water, its wind speed drops when it crosses land.
What are the two components of the oceans that work together to create storms with such strong winds?The hot, rising air of the storms contains ocean water vapor. When the vapor condenses into clouds, heat is released, warming the cornea and causing more surface water to evaporate, keeping the cycle running. The humidity and temperature of the air are other crucial factors.
What would happen if a hurricane crossed land or a body of cold water?As these storms travel across land or frigid water and are cut off from the hot water that fuels them, they become weaker and eventually evaporate.

An earthquake that measures 8 on the richter scale would be how many times stronger than an earthquake that measures 4 on the same scale?
Answer:
10,000 times stronger
Explanation:
An earthquake that measures 8 on the Richter scale would be 10,000 times stronger than an earthquake that measures 4 on the same scale. The Richter scale is a logarithmic scale, which means that each increment on the scale represents a tenfold increase in the amplitude of the earthquake's waves. So, an earthquake that measures 8 on the Richter scale would have waves that are 10,000 times more powerful than those of an earthquake that measures 4 on the scale.
A cylindrical pillar is 50 cm in diameter and 350 cm in height. Find the cost of painting the curved surface of the pillar at the rate of $12.50 per cm².
The cost of painting the curved surface of the pillar at the rate of $12.50 per cm² is $543,750.
What is curved surface area?Curved surface area (CSA) is the total area of all the curved surfaces of a three-dimensional object. It is different from the object's total surface area, which includes both curved and flat surfaces. CSA is important in determining the amount of material needed to cover a curved object and can be calculated from the object's surface area and total surface area. For example, a sphere has a total surface area of 4πr², but its curved surface area is 4πr², since the entire surface is curved.
The total area of the curved surface of the cylinder is given by A = 2πrh, where r is the radius and h is the height.
Therefore, the area of the curved surface of the cylinder is A = 2π(25 cm)(350 cm) = 43500 cm².
The cost of painting the curved surface of the pillar is then $12.50 per cm² x 43500 cm² = $543,750.
It can be concluded that the cost of painting the curved surface of the pillar at the rate of $12.50 per cm² is $543,750.

If an earthquake occurs at 02:11:20,
what time did the S-wave arrive at a seismic station 9,000 km away?
Answer:
If the average speed of s-waves is assumed, 4km/sec, then the time of arrival would be 02:11:57
Explanation:
It is not possible to determine the exact time that the S-wave from an earthquake would arrive at a seismic station 9,000 km away based on the information provided. The speed at which seismic waves travel through the Earth's crust can vary depending on the type of wave and the composition of the rock and soil through which it is passing. In general, however, S-waves (also known as secondary waves) travel at a slower speed than P-waves (also known as primary waves), so it would take longer for the S-wave from an earthquake to reach a seismic station located 9,000 km away. Additionally, the distance and direction of the seismic station from the earthquake's epicenter would also affect the arrival time of the S-wave. To determine the exact arrival time of the S-wave, it would be necessary to have more detailed information about the earthquake, the composition of the Earth's crust in the area, and the specific location of the seismic station.
We can use the average though.
Important:
If you were given a number for the speed of the s-waves that you did not share here, then to find the time, do the following:
9,000 ÷ time (In the case of 4km/sec, do 9000 ÷ 4)
Divide the result by 60. You now have the minutes it takes.
Add the result to 02:11:20.

how would you describe the composition of this rock? (hint: this rock contains primarily plagioclase feldspar and pyroxene)
Almost all rocks are minerals, but different rocks contain different mixtures of minerals. There are three main groups of rocks: sedimentary, igneous and metamorphic rocks.
Members of the plagioclase group are the most common rock-forming minerals. They are important for most of the dominant minerals in the igneous rocks of the earth's crust. They are the main components of many intrusive and extrusive igneous rocks, including granite, diorite, gabbro, rhyolite, andesite, and basalt. Rocks that contain many dark silicate materials and plagioclase in feldspar are basaltic in composition. Basalt rock contains minerals of the pyroxene group, which give the minerals their dark color.
It can be as light as dark green or as dark as black. Plagioclase (feldspar) is widespread and common in many igneous and metamorphic rocks, and to a much lesser extent in some immature sedimentary rocks. In general, the keys to identifying plagioclase are its absence (color), low birefringence, and twinning.
