The major absorber of terrestrial radiation is carbon dioxide. Human activities, such as burning fossil fuels, have led to an increase in the concentration of atmospheric Carbon dioxide.

When the Earth's surface absorbs solar radiation, it re-radiates some of that energy back into the atmosphere as infrared radiation. This outgoing radiation is then absorbed by certain gases in the atmosphere, including carbon dioxide, water vapor, and methane, which act as greenhouse gases. Carbon dioxide is particularly effective at absorbing infrared radiation because it has a molecular structure that allows it to vibrate in response to the radiation, which results in the molecule gaining energy. This absorption of energy causes the atmosphere to warm, which in turn causes global warming and climate change.

A three sigma process corresponds to a higher variation compared to a six sigma process. The "sigma" value in these terms represents the standard deviation, which is a measure of variation.

In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range. Standard deviation may be abbreviated SD, and is most commonly represented in mathematical texts and equations by the lower case Greek letter σ (sigma), for the population standard deviation, or the Latin letter s, for the sample standard deviation. The standard deviation of a random variable, sample, statistical population, data set, or probability distribution is the square root of its variance. It is algebraically simpler, though in practice less robust, than the average absolute deviation. A useful property of the standard deviation is that, unlike the variance, it is expressed in the same unit as the data.

Explanation:

As a wave approaches the shore, its speed, height, and length undergo changes due to the interaction with the shallow bottom of the ocean.

The speed of the wave decreases as it approaches the shore. This is because the wave encounters the shallower water near the shore and the wave's bottom part slows down due to the friction with the ocean floor, while the top part of the wave continues moving at a higher speed. This difference in speed causes the wave to bend, and the crest of the wave begins to align more parallel to the shore. This process is called wave refraction, and it causes the wave to move toward the shore at an angle. As the wave slows down, its length decreases, and its height increases. This is because the wave energy must be conserved, and as the wave approaches the shore, the same amount of energy must be distributed over a shorter distance. This process is called wave shoaling, and it causes the wave to steepen and increase in height. As the wave height increases, it can eventually become unstable and break, creating a surf zone.

As a wave approaches the shore, the wave speed decreases, the height increases, and the length decreases, respectively.

When a wave travels from deep water towards shallow water near the shore, its speed is affected due to the change in water depth. In deeper water, waves travel at higher speeds, but as they approach the shore and the water becomes shallower, their speed decreases. This is because the friction between the water and the ocean floor increases, causing the wave to slow down. As the wave slows down, its height increases. This occurs because the energy of the wave is conserved. When the wave's speed decreases, the energy has to go somewhere, so it is converted into an increase in wave height. The higher the wave, the more energy it contains.

Lastly, the wave's length decreases as it approaches the shore. The decrease in speed causes the waves to become compressed and closer together, leading to a shorter wavelength. This compression is due to the waves' interaction with the ocean floor and each other as they slow down, causing them to crowd together. In summary, when a wave approaches the shore, its speed decreases, its height increases, and its length decreases. This is primarily due to the interaction between the waves and the ocean floor in shallow water.

Answer: A rain shadow effect.

Explanation: A rain shadow is a patch of land that has been forced to become a desert because mountain ranges blocked all plant-growing, rainy weather. On one side of the mountain, wet weather systems drop rain and snow. On the other side of the mountain—the rain shadow side—all that precipitation is blocked.

The phenomenon you are describing is called a "rain shadow effect".

When air masses carrying moisture from the ocean encounter a mountain range, the air is forced to rise over the mountain. As the air rises, it cools and the moisture in the air condenses, forming clouds and precipitation on the windward side of the mountain. By the time the air reaches the leeward side of the mountain, it has lost much of its moisture, resulting in a dry, arid climate known as a "rain shadow".In the case of a desert, a mountain range can block moisture-laden air from reaching the desert, creating a rain shadow effect and contributing to the desert's arid climate. This is why many deserts are located on the leeward side of mountain ranges, such as the Mojave Desert in California, which is located on the eastern side of the Sierra Nevada mountain range.

Major environmental impacts on vegetation, lakes, human-built structures, and human health can result from various factors, including pollution, climate change, and deforestation.

Pollution, such as air and water contamination, can negatively affect vegetation and lakes by hindering growth, reducing biodiversity, and degrading overall ecosystem health. This can lead to a decline in the quality and availability of natural resources for humans and wildlife. Human-built structures can also suffer from pollution, especially in urban areas where acid rain caused by air pollution can erode buildings and infrastructure.

Climate change is another significant factor, with increased temperatures and extreme weather events causing adverse effects on vegetation, lakes, and human-built structures. Rising temperatures can alter plant growth patterns and reduce the ability of ecosystems to store carbon, exacerbating global warming. Warmer water temperatures in lakes can lead to harmful algal blooms, which impact water quality and aquatic life. Moreover, extreme weather events can cause structural damage to buildings, roads, and other infrastructure.

Deforestation poses a considerable threat to vegetation and biodiversity, as it involves the removal of large areas of natural habitat. This process disrupts ecosystems, affects the availability of resources, and contributes to climate change through the release of stored carbon.

Lastly, these environmental impacts can have direct and indirect consequences on human health. Polluted air and water can cause respiratory illnesses, while climate change can increase the spread of vector-borne diseases. Additionally, the degradation of ecosystems can reduce the availability of resources, potentially leading to malnutrition and socio-economic instability.
