how would you describe the composition of this igneous rock? (hint: this rock contains primarily plagioclase feldspar, biotite and amphibole)

Answers

Answer 1

The composition of this igneous rock is intermediate.

When hot, molten rock crystallizes and solidifies, igneous rocks named after the Latin word for fire are created. The melt begins deep within the Earth near hot regions or active plate borders, then it rises toward the surface. According to where the molten rock hardens, igneous rocks are categorized into two groups: intrusive and extrusive.

Magma becomes trapped in the Earth's interior and intrusive, or plutonic, igneous rock is created. Massive globules of molten rock are rising. While some of the magma may fuel volcanoes on the planet's surface, the majority is locked underground, where it slowly cools over tens of thousands or perhaps millions of years before solidifying. Since the individual mineral grains have a relatively long growth period due to the slow cooling.

Which of the factors affecting climate has the greatest impact on the climate in your region?
Think about:
The four factors affecting climate.
(im in california)

Answers

Factors influencing the Climate

Topography

The Topography of an area can greatly influence our climate. Mountain ranges are natural barriers to air movement. In California, winds off the Pacific ocean carry moisture-laden air toward the coast. The Coastal Range allows for some condensation and light precipitation.

Prevailing global wind patterns

Latitude affects climate. Two ways it does this is the amount of sunlight different latitudes receive and prevailing winds change at different latitudes. The sunlight distribution changes in that, because of the Earth’s tilt; the equatorial region receives the most sunlight of anywhere on earth. Because of this, the higher or lower you go in latitude away from the equator, the less sunlight and therefore, colder on average the area will be.

Relative Humidity

In general, relative humidities are moderate to high along the coast throughout the year. Inland humidities are high during the winter and low during the summer. Since the ocean is the source of the cool, humid, maritime air of summer, it follows that with increasing distance from the ocean, relative humidity tends to decrease. Where mountain barriers prevent the free flow of marine air inland, humidities decrease rapidly. Where openings in these barriers permit a significant influx of cool, moist air it mixes with the drier inland air, resulting in a more gradual decrease of moisture. This pattern is characteristic of most coastal valleys.

Floods

In southern California, most flooding is the result of heavy precipitation over periods of one or two days. The short streams and steep watersheds emptying onto lowlands that may be heavily populated, produce large volumes of water within short periods and damage is often severe. The problem is sometimes compounded by the denuding of large areas of the watershed by fire during the previous season.

The west slopes of the coastal ranges in the central and northern parts of the state also experience flooding as a result of heavy precipitation over a period of only a few days. These streams are usually longer than those of southern California and require a longer time to build up a flood potential. The Eel and Klamath Rivers, as well as others in the northwestern part of California, are larger streams

what is the relationship between climate change and the regularity of droughts​

Answers

Some climate models find that warming increases precipitation variability, meaning there will be more periods of both extreme precipitation and drought. This creates the need for expanded water storage during drought years and increased risk of flooding and dam failure during periods of extreme precipitation.

Hope it helps...

The relationship between climate change and the regularity of droughts​ is that warmer temperatures experienced results in the drying out of soil and vegetation with a corresponding decrease in precipitation.

a. Glass walls
b.Steep roof
c. Claustra-work
d. Grass and reed surfaces

Answers

According to Hassan Fathy, glass walls are not a suitable design strategy for a building constructed in the tropics. This is because glass walls absorb heat and cause the building's interior to become too hot during the day, making it difficult to maintain a comfortable indoor temperature.

The design of buildings in the tropics must take into account the region's hot and humid climate. Fathy advocated for using local materials and techniques to construct buildings that are sustainable, cost-effective, and energy-efficient. He was against the use of modern building techniques and materials that were often imported and unsuitable for the local climate. Instead, he encouraged the use of mud brick, adobe, and other natural building materials that were readily available in the region.Fathy's design strategies emphasized the importance of passive cooling and ventilation in buildings. He believed that buildings should be oriented to take advantage of the prevailing winds and natural ventilation. He also recommended the use of high ceilings, courtyards, and roof overhangs to help reduce the temperature inside buildings.He was against the use of air conditioning and other mechanical cooling systems because they are expensive, consume a lot of energy, and are often not suitable for the local climate. Fathy also believed that buildings should be designed to blend in with the local environment and reflect the culture and traditions of the local community.

Glass walls are not a suitable design strategy for a building constructed in the tropics because they absorb heat and cause the building's interior to become too hot during the day, making it difficult to maintain a comfortable indoor temperature. Furthermore, glass walls are prone to breakage, which may be harmful to the occupants of the building.

The similarity about the discoveries of Neptune and Pluto is: they were both identified as planets by virtue of their movement in the sky. The Option D is correct.

What is similar about the discoveries of Neptune and Pluto?

We have few similarities in the discoveries of Neptune and Pluto:

Both planets were discovered through mathematical predictions rather than direct observations. In the case of Neptune, astronomers noticed discrepancies in the orbit of Uranus, which led them to calculate the location of an unknown planet. Similarly, the discovery of Pluto was based on observations of irregularities in the orbit of Neptune.

The discoveries of both Neptune and Pluto were made by American astronomers. Neptune was discovered by Urbain Le Verrier, a French mathematician, but its existence was confirmed by American astronomer Johann Galle. Pluto was discovered by American astronomer Clyde Tombaugh.

Both Neptune and Pluto are located in the outer reaches of our solar system. Neptune is the eighth planet from the sun, while Pluto is the ninth (although it has since been reclassified as a dwarf planet).

which of the following locations would most likely contain large, angular rocks?

Answers

Large, angular rocks are most likely to be found in areas that are subjected to weathering conditions. The type of rocks found in a location often depends on several factors including the type of rock formation in the area, geological history of the region, weathering and erosion conditions, and climatic conditions. Some of the most common locations where large angular rocks can be found include:



1. Mountains: Angular rocks are often found in mountainous regions where there are several rock outcrops. The rocks found in these regions are often subjected to weathering and erosion by wind, water, and ice, leading to the formation of large angular rocks.

2. Glaciers: Glaciers are known for their ability to transport rocks of various sizes over long distances. The rocks transported by glaciers are often angular, and they often form moraines when the glacier recedes.

3. Riverbeds: Riverbeds are often characterized by large angular rocks, boulders, and cobbles. The rocks in riverbeds are often transported by water, and they undergo several cycles of abrasion, which results in the formation of angular rocks.

4. Deserts: Large angular rocks can also be found in desert regions. The rocks in these regions are often subjected to weathering by wind and sand, leading to the formation of angular rocks.

A very small population of a species faces a greater threat of extinction than a larger population. Smaller population faces more random fluctuation, which may result in greater death rate than birth rate and that ultimately leads to their extinction

Answers

A very small population of a species faces a greater threat of extinction than a larger population.

Smaller population faces more random fluctuation, which may result in greater death rate than birth rate and that ultimately leads to their extinction. The greater threat of extinction faced by smaller populations is often a result of genetic drift, which can lead to the loss of genetic variation and the accumulation of deleterious mutations. Genetic drift is more likely to occur in small populations because chance events can have a greater impact on the genetic composition of the population.

Smaller populations also face a greater risk of inbreeding, which can lead to reduced genetic diversity and increased susceptibility to disease and other threats. In addition, smaller populations may be more vulnerable to habitat loss, climate change, and other environmental pressures, which can further reduce their numbers and increase their risk of extinction.

Overall, the small population size can cause a species to be at a greater risk of extinction than the larger population because smaller populations face more random fluctuations that may result in the greater death rate than birth rate.

The formula for the half-life is obtained by dividing 0.693 by the constant λ. Here λ is called the disintegration or decay constant.

What is Half-life formula?

To determine the half-life of a material whose amount is reducing or decaying, one uses the half-life formula. The pace at which a chemical degrades varies depending on how much of the material is present. Finding the life of a decaying material is highly challenging since as the quantity of the substance decreases, the rate of decay likewise slows down. In order to determine the life of decaying material, the half-life formula is utilized to provide the appropriate metrics.

The term "half-life" describes how long it takes for half of a given sample to respond, or how long it takes for a given quantity to go from its starting value to half. The half-life formula is frequently applied in nuclear physics to characterize the rate of radioactive decay of an atom.

(choose all that apply)

Answers

The processes that triggered the landslides during the 2018 Hokkaido Iburi-Tobu earthquake include liquefaction and the presence of weak pumice layers. Liquefaction occurs when saturated granular materials, such as sandy or silty soils, lose their strength and behave like a liquid during strong shaking. I

Pumice is a lightweight volcanic rock formed from the rapid cooling of frothy lava that contains high amounts of gas bubbles. It is highly porous and has low density, which makes it prone to collapse and compaction when subjected to external forces. The interbedded layers of pumice in the underlying geology of the area contributed to the vulnerability of the slopes.

During the earthquake, the ground shaking caused the pumice layer to lose its strength and compact, creating a fluid-like behavior. The liquefied pumice layer acted as a lubricant, reducing the friction between particles and making the slope material unstable. As a result, the slopes became prone to failure, leading to widespread landslides.

The combination of intense shaking, saturation of the volcanic soils, and the presence of weak pumice layers created a perfect storm for the triggering of landslides. The liquefaction of the weak pumice layer played a significant role in initiating the slides and amplifying the overall devastation caused by the earthquake.
