Mechanical weathering occurs by temperature and pressure changes. Chemical weathering occurs particularly when the water is slightly acidic.

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.

Seasons are caused by the tilt of Earth's axis as it circles the Sun. During such time, the hemisphere oriented towards the Sun (north or south) receives more heat. The seasons are not caused by the Sun's proximity.

A season is a division of the year that is based on variations in weather, ecology, and the amount of daylight hours in a certain place. Seasons occur on Earth because to the axial parallelism of the Earth's tilted orbit around the Sun.

Seasons are distinguished in temperate and polar regions by differences in the amount of sunlight that reaches the Earth's surface, which may drive animals to hibernate or migrate, and vegetation to become dormant. Various civilizations define the number and character of seasons depending on geographical variances, and as a result, the number of seasons differs throughout both current and historical cultures.

Option A, According to the Mount Pinatubo particulate model, the fine debris and sulfur dioxide that was first released into the atmosphere moved from East to West.

One of the biggest volcanic explosions of the 20th century was the Mount Pinatubo outburst in 1991. The explosion significantly altered the climate of the entire planet by releasing millions of tons of ash and sulfur dioxide into the sky.

According to the eruption's particle model, the easterly trade winds were what caused the erupted material's original atmospheric movement, which was from east to west. The material was ultimately spread to higher altitudes by the dominant westerlies, which led to a drop in world temps and a rise in atmospheric aerosols. One of the most important events in history was the explosion of Mount Pinatubo.

The above phenomenon of wavy bands of light and dark minerals visible in gneiss bedrock probably formed from the heat and pressure during the process of metamorphism.

What is metamorphism?

When solid rocks undergo physical-chemical changes as a result of factors like crustal movement, magma activity, or changes in the earth's thermal fluids, new mineral assemblages and textures are created. Re-crystallization, metamorphic crystallization, deformation, fragmentation, and alternation are all components of metamorphism. Metamorphic rock, whose chemical composition is related to both the original rock and metamorphism, is the result of existing rock (igneous and sedimentary rocks) undergoing metamorphism.

So, it is the process of metamorphism which causes wavy bands of light and dark minerals in gneiss bedrock. Hence, heat and pressure play a major role in the formation of the same.

Answer: In a topographic profile, the horizontal scale represents the distance along the profile, while the vertical scale represents the elevation. If the vertical scale is 1:50,000 and the vertical exaggeration is 5, this means that the vertical distance on the profile is exaggerated by a factor of 5, while the horizontal distance is not affected.

To determine the horizontal scale, you need to know the actual distance represented by the profile. Let's say, for example, that the profile represents a distance of 10 kilometers. In this case, the vertical scale of 1:50,000 means that every 1 unit of vertical distance on the profile represents 50,000 units of actual elevation (i.e., meters). The vertical exaggeration of 5 means that this vertical distance is multiplied by 5, so every 1 unit of vertical distance on the profile actually represents 250,000 units of actual elevation.

To convert this to a horizontal scale, you need to determine the ratio of the distance represented by the profile to the distance on the page. Let's say that the profile is printed on a page that is 20 centimeters wide. If the actual distance represented by the profile is 10 kilometers (or 10,000 meters), then the ratio of the distance on the page to the actual distance is:

20 centimeters / 10,000 meters = 1:500,000

This means that every 1 unit of horizontal distance on the profile represents 500,000 units of actual distance. So the horizontal scale of the profile is 1:500,000.

In a topographic profile, the horizontal scale would be 250 meters when the vertical scale is 1:50,000 and the vertical exaggeration is 5. This can be calculated by multiplying the vertical scale (1:50,000) by the vertical exaggeration (5), resulting in a vertical scale of 1:10,000. Then, divide the length of the profile by the horizontal scale (which is the same as the map scale of 1:50,000), resulting in 250 meters.

In a topographic profile, the horizontal scale can be determined using the vertical scale and the vertical exaggeration. Here's a step-by-step explanation:

1. Vertical scale: 1:50,000
2. Vertical exaggeration: 5
3. Divide the vertical scale by the vertical exaggeration to find the horizontal scale: (1:50,000) / 5

Horizontal scale = 1:(50,000 * 5) = 1:250,000
So, in this topographic profile, the horizontal scale is 1:250,000.

The weather balloon is 83.134 miles away from the Western station.

To solve this problem, we can use trigonometry and the concept of bearings. Let's break down the information provided:

We need to find the distance between the western station and the weather balloon.

Let's assume the distance between the western station and the weather balloon is 'x' miles.

Using the concept of bearings, the angle between the bearing of N37°E and the bearing of N°E is 37° (since both bearings are measured from the north).

Now, we can form a right-angled triangle using the given information. The distance between the tracking stations (138 miles) forms the base of the triangle, the distance from the eastern station to the weather balloon (x miles) forms the vertical side of the triangle, and the distance from the western station to the weather balloon forms the hypotenuse of the triangle.

Using trigonometry, we can use the sine function to relate the angle and the sides of the triangle:

sin(37°) = x/138

Rearranging the equation:

x = 138 * sin(37°)

Calculating the value:

x ≈ 138 * 0.6018

x ≈ 83.134

Therefore, the weather balloon is approximately 83.134 miles away from the Western station.

As traditional economies are small, they are not as environmentally destructive as developed economies. They don't have the capacity to produce much more than what they require. Traditional economies generate very little waste.

Fundamental economic decisions in traditional economies, such as the production and distribution of goods and services, are determined by tradition and societal needs rather than monetary profit potential.

People in traditional economies typically trade or barter instead of using money, and their livelihoods are based on agriculture, hunting, fishing, or a combination of the three.

Traditional economies are commonly found in rural areas of developing second and third-world countries, particularly in Africa, Latin America, Asia, and the Middle East. Traditional economies are based on a family or tribe.
