In general, when rock is partially melted, the chemistry of the melt is:_____.

a. more mafic than the original chemistry of the rock that was partially melted.

b. more felsic than the original chemistry of the rock that was partially melted.

c. identical to the original chemistry of the rock that was partially melted.

d. completely unpredictable (it could be more mafic or more felsic).

Answers

Answer 1

In general, when rock is partially melted, the chemistry of the melt is completely unpredictable (it could be more mafic or more felsic).

The correct option is (d).

When rock undergoes partial melting, the resulting melt can have a different composition compared to the original rock. The chemistry of the melt depends on various factors such as the composition of the rock, the temperature, and the pressure conditions during melting. Different minerals within the rock have different melting points, and as the rock partially melts, certain minerals may preferentially melt, leading to changes in the overall chemical composition of the melt. Therefore, the chemistry of the melt can vary and may be more mafic (richer in magnesium and iron) or more felsic (richer in silica) compared to the original rock. It is not possible to predict the exact chemistry without considering the specific conditions of the melting process.

So, the correct answer is (d) completely unpredictable (it could be more mafic or more felsic).

(ch7) true or false? we should use a normal distribution to model the number of years until the next florida hurricane strike.

Answers

It is false to use a normal distribution to predict how many years it will be before another storm hits Florida.

Data close to the mean are more likely to occur than data distant from the mean, according to the normal distribution, which is symmetric around the mean.

Additionally, it offers a precise description of the value distribution for many natural occurrences.

Therefore, it is not ideal to estimate the number of decades until the next storm strikes Florida using a normal distribution.

This is untrue since it does not apply.

Assume that a parcel of air at the surface has a tem- perature of 29°C and a relative humidity of 50%. If the parcel rises, at what altitude should clouds begin to form?

Answers

Clouds will begin to form when the parcel of air reaches an altitude where the temperature cools down to 19°C.

Temperature

The altitude at which clouds begin to form depends on the temperature and relative humidity of the parcel of air. As the parcel rises, it cools down due to decreasing air pressure and expands in volume.

If the temperature cools down to the dew point temperature, which is the temperature at which the air becomes saturated with water vapor, clouds will begin to form.

To calculate the dew point temperature, we can use the formula:
Td = T - ((100 - RH)/5)

where

Td is the dew point temperature, T is the temperature in Celsius, and RH is the relative humidity in percent.

Plugging in the given values, we get:
Td = 29 - ((100 - 50)/5) = 19°C

Therefore, clouds will begin to form when the parcel of air reaches an altitude where the temperature cools down to 19°C.

The actual altitude depends on various factors such as the atmospheric pressure, lapse rate, and moisture content, but it typically ranges from a few hundred meters to several thousand meters above the surface.

Which of these Galilean satellites is most geologically active? a. Io b. Europa c. Callisto d. Ganymede

Answers

Among the Galilean satellites of Jupiter, Europa and Io are the most geologically active. Europa is known for its icy crust, which conceals a subsurface ocean of liquid water. The correct answer is option (d).

The tidal forces exerted by Jupiter and the other Galilean moons cause significant tidal heating within Europa, resulting in geological activity. This activity is evident through the presence of cracks, ridges, and chaotic terrains on Europa's surface.

Scientists believe that the subsurface ocean and geological activity may provide favorable conditions for the existence of life. Lo, on the other hand, is the most volcanically active body in the solar system.

It experiences intense tidal heating caused by the gravitational interactions between Jupiter, Europa, and Ganymede. This tidal heating generates significant internal heat, resulting in volcanic eruptions and the formation of volcanic plumes and lava flows on Io's surface.

In conclusion, Europa and Io are the most geologically active among Jupiter's Galilean satellites. Europa's geological activity is driven by its subsurface ocean, while Io's activity is due to intense tidal heating. The study of these moons provides valuable insights into the geological processes occurring within the solar system. Thus, option d is correct.

When the Moon crosses the western side of the horizon plane it is:A. RisingB. Setting

Answers

When the Moon crosses the western side of the horizon plane, it is setting.

This is because the Moon appears to be moving in a westerly direction across the sky as the Earth rotates on its axis from west to east.

As the Moon moves closer to the western horizon, its light has to pass through more of the Earth's atmosphere, which can scatter the shorter blue wavelengths of light.

Make the Moon appear reddish or orange. This effect is known as atmospheric refraction.

The opposite of setting is rising, which occurs when the Moon appears to move upwards from below the eastern side of the horizon plane as the Earth rotates on its axis.

The Moon's phases and its position in its orbit around the Earth will determine the time of day and direction in which it rises and sets.

the amount and timing of precipitation a region receives is ultimately controlled by ______.

Answers

The amount and timing of precipitation a region receives is ultimately controlled by its climate, which is determined by a variety of factors, including latitude, altitude, distance from large bodies of water, prevailing winds, and topography.

These factors affect the amount of solar radiation that a region receives, the amount of moisture in the air, and the patterns of atmospheric circulation. For example, regions near the equator receive more solar radiation and are generally warmer than regions at higher latitudes. This leads to differences in atmospheric pressure and circulation patterns, which can affect the amount and timing of precipitation. In addition, topography plays an important role in determining the amount and timing of precipitation. Mountain ranges can cause moist air to rise and cool, leading to precipitation on the windward side of the mountains. On the leeward side of the mountains, however, the air is often dry and can lead to arid or semi-arid conditions. Overall, the complex interplay of these factors ultimately determines the climate and precipitation patterns of a region.

3. What are four reasons for the differences between

Answers

1. El Niño is not an example of climate change in itself. El Niño is a natural climate phenomenon that occurs in the Pacific Ocean and is characterized by the warming of surface waters, altering atmospheric circulation patterns. It is a part of the broader climate variability known as the El Niño-Southern Oscillation (ENSO) cycle, which also includes its cold phase called La Niña. Climate change, on the other hand, refers to long-term shifts in global or regional climate patterns due to human-induced factors such as greenhouse gas emissions. While climate change can influence the frequency and intensity of El Niño events, El Niño itself is not caused by climate change.

2. Earth's climate is unique due to several factors:

  a) The presence of liquid water: Earth is the only known planet with large amounts of liquid water on its surface, which plays a crucial role in regulating the climate system.

  b) The greenhouse effect: Earth's atmosphere contains greenhouse gases that trap heat and maintain a habitable temperature range, allowing life to thrive.

  c) Complex atmospheric circulation patterns: Earth's rotation, along with the distribution of land masses and oceans, drives the circulation of air masses and ocean currents, influencing regional climates.

  d) Solar radiation and axial tilt: The Earth's distance from the sun and its axial tilt result in seasonal variations, shaping the climate patterns on a yearly basis.

  e) Dynamic feedback mechanisms: Earth's climate system consists of various feedback loops that can amplify or dampen climate changes, leading to complex interactions and non-linear responses.

Answers

The given statement, "Salt domes create geologic structures called traps where oil and natural gas accumulate within the ground" is true because salt is less dense than the surrounding rocks.

Salt domes are an important geologic structure, forming when salt beds are compressed deep beneath the Earth's surface and push upward, creating a dome-shaped structure.

These salt domes can be quite large and have the capacity to create a trap for oil and natural gas due to the fact that the salt is less dense than the rocks that surround it. This causes the salt to rise, forming an upward dome and trapping the oil and natural gas that accumulate within it.

Answers

The economic system in the New World that involved the granting of land to a Spanish "ruler" and the servitude of Native American workers was called the Encomienda system.

This system was put in place by the Spanish government in the 16th century as a way to reward conquistadors for their service and to establish control over the newly acquired territories in the Americas. The Spanish rulers, or encomenderos, were granted large tracts of land and were given the right to demand tribute and labor from the indigenous people living on the land. This system allowed the Spanish to exploit the resources of the New World and establish a foothold in the Americas. However, it also led to the abuse and exploitation of Native American workers who were forced to work under harsh conditions. The Encomienda system was eventually abolished in the mid-16th century due to the protests of Spanish priests and other critics who argued that it was a form of slavery and violated the rights of indigenous people.
