how are minerals classified? give an example of each types of minerals
Answers
Answer:
Mineral classification is based upon the chemical composition of the minerals. There exist at least 3000 different kinds of minerals which makes it necessary to have a system to classify them.
Carbonates are a class of minerals that are composed of carbon, oxygen, together with a metallic element. Calcite better known as calcium carbonate is an example of a mineral of this type.
Halides are made up of halogen elements like bromine, chlorine, fluorine and iodine, together with metallic elements. Halides are super soft and are highly soluble in water. A common example under this category is halite which is known as sodium chloride.
Mineraloids are those minerals that do not fit perfectly into the other 8 classes of minerals. They include: amber, jet, mother of pearl and opal.
Native elements are a class of pure minerals. A lot of minerals exist in combinations of numerous chemical compounds. Native elements are those that occur naturally in a pure state, for example copper is a single element mineral.
Oxides arise when metals are combined with oxygen. This class consists of dull ores such as bauxite and gems such as sapphire and ruby.
Phosphates are created when there is break down of other minerals through weathering. They are usually bright in color and do not occur as much as the other groups of minerals.
Silicates form the largest family of minerals. They arise from the combination of metals with oxygen and silicon. There exist more silicates on earth than all the other minerals added together. Mica is a common example under this category.
Sulfates form from the combination of sulfur compounds with oxygen and metals. This is also a large family of minerals, which are soft and translucent in nature. Barite is a good example of a sulfate.
Sulfides are composed of sulfur compounds often together with a metal. They are heavy and brittle in nature. Pyrite is an example of a sulfide.

The electromagnetic spectrum, visible light occupies the band between 0.4 and 0.7 in "Micrometers"
The electromagnetic spectrum is the range of frequencies of electromagnetic radiation and their respective wavelengths and photon energies.
Electromagnetic radiation is consists of waves of the electromagnetic field, propagating through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, light, ultraviolet, X-rays, and gamma rays. All of these waves form part of the electromagnetic spectrum.
Electromagnetic radiation is produced whenever a charged particle changes its velocity i.e., whenever it is accelerated or decelerated. The energy of the electromagnetic radiation thus produced comes from the charged particle and is therefore lost as it gets discharged.

differential stress will cause crystals to align in a preferred orientation unless the crystals are ____________.
Answers
Differential stress will cause crystals to align in a preferred orientation unless the crystals are equant.
An equant or equidimensional crystal has almost the same side length in all directions. Garnet crystals frequently have an equant tendency. Certain mineral species' crystals can occasionally take on quite recognizable forms. Thus, crystal habit is frequently helpful for identification.
One aspect that will impact a developing crystal's final form is the direction from which it could acquire such solutions. The pace at which the environment cools affects how long a mineral is given to form massive crystals. Higher ambient temperatures during formation improve ion mobility and help in crystal formation. The ultimate form and size of a crystal depend on the amount of space it has to fill.

Moist air undergoes a heating and humidification process at a pressure of 101.325 kPa from an initial state of 15°C db and 80% relative humidity to a final state at 22ºC and 60% relative humidity. If the mass flow rate of the air at the initial state is 27.7 kg da/s, what is the increase in the water content of the air? Express your answer in kg/s. In your written solution, draw the process in the psychrometric chart, show the initial and final state and the values obtained from the chart.
Answers
If the mass flow rate of the air at the initial state is 27.7 kg da/s , then the increase in the water content of the air is -0.039648 kg/s.
How to find?The process can be drawn on a psychrometric chart as shown below:
In order to solve the problem, the following steps are to be followed:
Step 1: Find the Humidity Ratio at state 1
The Humidity Ratio (ω1) can be found using the formula:
\(Relative Humidity (RH1) = (ω1/ωsat) × 100\)
Where,
ω1 = Humidity Ratio at State 1
ωsat = Saturation Humidity Ratio at State 1
The value of saturation humidity ratio (ωsat) can be obtained from the psychrometric chart.
ωsat at State 1 corresponds to temperature T1 and 100% relative humidity.
From the chart,ωsat = 0.012 kg water/kg dry air.
Therefore,
RH1 = (ω1/ωsat) × 100
80% = (ω1/0.012) × 100ω1
= (80/100) × 0.012
= 0.0096 kg water/kg dry air.
Step 2: Find the Humidity Ratio at state 2The Humidity Ratio (ω2) can be found using the formula:
RH2 = (ω2/ωsat2) × 100
From the chart,ωsat2 = 0.0136 kg water/kg dry air.
Therefore,
RH2 = (ω2/ωsat2) × 10060%
= (ω2/0.0136) × 100ω2
= (60/100) × 0.0136
= 0.00816 kg water/kg dry air.
Step 3: Find the increase in Humidity Ratio
Increase in Humidity Ratio \((Δω) = ω2 - ω1Δω\)
= 0.00816 - 0.0096
= -0.00144 kg water/kg dry air.
The negative sign indicates that there is a decrease in the water content of the air.
Step 4: Find the Mass flow rate of water
Mass flow rate of water can be found using the formula:
Mass flow rate of water = Mass flow rate of dry air x ΔωMass flow rate of water
= 27.7 x (-0.00144)
= -0.039648 kg/s.
Therefore, the increase in the water content of the air is -0.039648 kg/s.

What causes the winds of a hurricane to be so fast? coupling with the jet stream very strong pressure gradient force strong tidal effects strong coriolis effect
Answers
stronger Coriolis force causes the winds of a hurricane to be so fast, coupling with the jet stream very strong pressure gradient force strong tidal effects strong coriolis effect.
The Coriolis force, which operates on moving objects inside a frame of reference that rotates relative to an inertial frame, is an imaginary or inertial force in physics.
The force applies to the left of the object's motion in a reference frame with clockwise rotation.The force acts to the right in an anti clockwise (or counterclockwise) rotating system.
The Coriolis effect is the bending of an object caused by the Coriolis force. The Coriolis force's mathematical expression first appeared in an 1835 paper by French scientist Gaspard-Gustave de Coriolis in conjunction with the theory of water wheels, even though it had been known to others earlier.
The Coriolis force became known in meteorology at the beginning of the 20th century.

Answers
Modern infrastructure is not complete without dams, which impound water for agriculture, hydroelectric power generation, navigational flow releases, and flood control.
Around 2.8 million medium and large dams exist in the world, which have changed the flow patterns and longitudinal connectivity of the majority of the rivers. Dams have a variety of effects on river systems upstream and downstream by changing flow regimes, obstructing fish and other creatures from migrating, and trapping silt, nutrients, and other elements in flux. Entrapped sediments can fill reservoirs, taking up space that could have been used to store water.
Dams may need renovation for a variety of reasons. Deterioration of the dam itself (such as the frequently observed issues with concrete swelling and weakening due to alkali-aggregate reaction and similar processes), risk of failure from an earthquake or landslides into the reservoir, risk of overtopping due to altered hydrology, sediment buildup endangering the dam's ability to provide services in the long run, and evolution of the dam's expectations, such as higher environmental standards, are some examples.

Answers
The winds or motions of the gases at Jupiter's core would be expected to be a mixture of hydrogen, helium, and much smaller amounts of methane and ammonia.
Jupiter is almost entirely composed of hydrogen and helium, and these elements are gases on Jupiter's and Earth's surfaces. Inside Jupiter, however, hydrogen can be a liquid or even a metal. These changes occur as a result of the extreme temperatures and pressures found at the core. Under low pressure, molecules of hydrogen and helium have plenty of room to bounce around. This is the state in which hydrogen and helium are gases.
However, the weight of all of this hydrogen and helium is enormous. This weight exerts tremendous pressure on the Jupiter's core. When the molecules run out of space to bounce around, they slow down and crowd together. This results in the formation of a liquid.

White coatings on roofs increase solar reflectance and reduce heat absorption. Gray asphalt shingles demonstrate greater temperature changes than white cement tile roofs. Red clay tile roofs have a lower reflectance compared to white cement tile roofs.
Explanation:A) True. White coatings on roofs increase solar reflectance because they have a high reflectance, which means that they reflect more energy away from the building. This helps to reduce the amount of heat absorbed by the roof.
B) False. The bar graph shows that white cement tile roofs have a higher solar reflectance compared to gray asphalt shingles. Therefore, white cement tile roofs demonstrate greater temperature changes due to their higher reflectance.
C) False. The bar graph shows that red clay tile roofs have a lower solar reflectance compared to white cement tile roofs. Therefore, red clay tile roofs have a lower reflectance and are likely to have a higher temperature compared to white cement tile roofs.
D) False. The scatter plot shows that as the solar reflectance of a roof increases, the maximum temperature rise decreases. This means that there is a negative correlation between solar reflectance and roof temperature.
E) False. The scatter plot does not provide specific temperature rise data for white coating roofs or gray asphalt shingles. Therefore, we cannot directly compare the temperature rise between these two materials based on the given graphs.

Answers
About 2.5-2.3 billion years ago, oxygen levels begin to increase in the Earth's atmosphere.
The majority of experts concur that oxygen levels in the atmosphere and water were incredibly low throughout the first two billion years. However, the amount of oxygen in the atmosphere began to rise about 2.5–2.3 billion years ago. The geologic consequences of this are clear: suddenly, rocks on land that were exposed to the environment started turning red as a result of iron reacting with oxygen to generate iron oxides, which are comparable to how iron metal rusts.
When compared to today's level, atmospheric oxygen levels peaked around this time, according to calculations by Earth scientists, but they stayed too low to oxygenate its deep ocean, which remained essentially anoxic.
