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.

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.

The current rise in global sea level can be attributed to the melting of glaciers

Hence, option (D) is the correct choice.

Sea level rise is caused by ice melting from land into the ocean, warming seas that expand, a decreasing Gulf Stream, and sinking land.

Sea-level rise will also have an influence on coastal and shallow marine plants and animals, such as mangroves and coral reefs. There will be a combined danger of river floods and coastal flooding in nations with extensive amounts of coastal lowland, reducing the area for living and working.

Sea level rise is principally caused by two global warming-related factors: the addition of water from melting ice sheets and glaciers, and the expansion of saltwater as it heats. The first graph depicts the change in global sea level detected by satellites since 1993.

The cloud formation labelled A is a cumulonimbus cloud. Cumulonimbus clouds are the tallest and most massive clouds in the troposphere, the lowest layer of Earth's atmosphere. They are typically associated with thunderstorms, heavy rain, hail, and lightning.

Cumulonimbus clouds are formed when warm, moist air rises rapidly. As the air rises, it cools and condenses, forming water droplets. The water droplets grow larger and larger as they rise, eventually forming clouds.

Cumulonimbus clouds can be very tall, reaching heights of up to 20 kilometers (12 miles). They can also be very wide, covering an area of up to 100 kilometers (62 miles).

Cumulonimbus clouds are most common in the tropics, but they can occur anywhere in the world. They are most common during the summer months, when the air is warm and humid.

Explanation:

As compared to subaerial basaltic lavas, submarine basaltic lavas differ in that they form pillow-like mounds because they cannot flow as far from their source. So, option c. is correct.

Subaerial basaltic lavas, which flow on the Earth's surface exposed to air, can flow for longer distances due to lower cooling rates and solidification. In contrast, submarine basaltic lavas, which are erupted under water, experience rapid cooling and solidification upon contact with water. This rapid cooling process causes the submarine basaltic lava to form pillow-like mounds, also known as pillow basalts. These mounds are characterized by their round or elongated shapes, formed as the outer layer of the lava solidifies and the still-liquid lava within breaks through, creating a new pillow. It is important to note that submarine basaltic lavas do not always produce violent pyroclastic debris flows, nor do they necessarily produce large crystals of pyroxene and plagioclase.

The formation of large crystals depends on various factors, such as cooling rate and chemical composition of the lava. In general, the key difference between submarine and subaerial basaltic lavas lies in their cooling processes and the resulting morphologies, with submarine lavas forming pillow-like mounds due to their limited flow distance from the source. So, option c. is correct.

https://brainly.com/question/30834852

#SPJ11

The correct answer is c. Submarine basaltic lavas form pillow-like mounds because they cannot flow as far from their source as subaerial basaltic lavas. This is due to the higher pressure and cooler temperatures of the ocean environment, which causes the lava to solidify more quickly and form distinctive pillow shapes.

Additionally, submarine basaltic lavas tend to have smaller crystals of pyroxene and plagioclase due to the rapid cooling process, while subaerial lavas may have larger crystals due to slower cooling on the surface. There is generally less explosive activity associated with submarine basaltic lavas compared to subaerial lavas, so they do not typically produce violent pyroclastic debris flows. Submarine basaltic lavas differ from subaerial basaltic lavas in that they cool much more rapidly due to the surrounding cold water, which can cause them to form distinctive pillow-shaped mounds of rock. In contrast, subaerial basaltic lavas have a chance to flow longer distances before cooling, resulting in more extensive lava flows with characteristic flat, smooth surfaces. Submarine basaltic lavas can also have different chemical compositions than subaerial basaltic lavas, due to differences in the conditions under which they form.

A long sand body more or less parallel with a shoreline but separated from it by a lagoon is a  barrier island.

Barrier island is form as waves repeatedly deposit sediment parallel to the shoreline. As wind and waves shift according to weather patterns and local geographic features, these islands constantly move, erode, and grow. They can even disappear entirely.

These islands are critical to protecting coastal communities and ecosystems from extreme weather. Beach dunes and grasses on barrier islands absorb wave energy before the wave hits the mainland. This generally means smaller storm surge and less flooding on the coast/ shoreline.

When stress is released in real life, the body's relaxation response is activated, which leads to a decrease in the levels of stress hormones.

The body's response to stress involves the release of stress hormones such as cortisol and adrenaline, which prepare the body for a fight or flight response. However, when the stressor is removed or managed effectively, the body's relaxation response is activated.

This response triggers a decrease in heart rate, blood pressure, and breathing rate, leading to a state of calmness and relaxation. Additionally, the levels of stress hormones in the body decrease as the relaxation response takes over.

This reduction in stress hormones can have positive effects on overall health and well-being, including improved sleep, reduced anxiety, and increased immune system functioning.

Soil organic matter depletion is a major problem that affects the physical and chemical properties of Savanna Ochrasols in Thana. Organic matter plays a crucial role in maintaining soil structure, water holding capacity, nutrient availability, and soil fertility. When organic matter is depleted, it leads to soil degradation and reduced crop productivity.

Soil organic matter depletion is a major problem that affects the physical and chemical properties of Savanna Ochrasols in Thana. Organic matter plays a crucial role in maintaining soil structure, water holding capacity, nutrient availability, and soil fertility. When organic matter is depleted, it leads to soil degradation and reduced crop productivity.

The loss of organic matter affects the physical properties of soil, such as soil structure, porosity, and aggregate stability. This results in poor water infiltration, compaction, and erosion, making it difficult for crops to access water and nutrients from the soil. The reduced porosity also limits the movement of air in the soil, which is essential for root respiration and growth.

Furthermore, organic matter is a source of nutrients, and its depletion affects the chemical properties of soil. The loss of organic matter leads to a decline in soil fertility, and essential nutrients, such as nitrogen, phosphorus, and potassium, become limited. As a result, crop yields decrease, and farmers have to rely on chemical fertilizers to compensate for the loss of organic matter.

In conclusion, soil organic matter depletion is a critical issue that affects the physical and chemical properties of Savanna Ochrasols in Thana. To maintain soil fertility and crop productivity, farmers should adopt sustainable practices such as crop rotation, cover cropping, and composting to increase organic matter in the soil. These practices promote soil health, reduce soil degradation, and support sustainable crop production in Ghana.
