Name one way in which radiation is lost as it travels through the atmosphere.
One way in which radiation is lost as it travels through the atmosphere is that some of the wavelengths of solar radiation travelling through the atmosphere may be lost because they are absorbed by various gases. Ozone completely removes UVC, most UVB, and some UVA from incoming sunlight. O2, CO2 and H2O also filter out some wavelengths.
What is radiation?Radiation is energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it and has wave-like properties.
Some of the most familiar sources of radiation include the sun, microwave ovens in our kitchens and the radios we listen to in our cars. Most of this radiation carries no risk to our health. In general, radiation has a lower risk at lower doses but can be associated with higher risks at higher doses.
Depending on the type of radiation, different measures must be taken to protect our bodies and the environment from its effects, while allowing us to benefit from its many applications.

In looking at Figure 16.2, Stampede Pass and Bend both have elevations between 3500-4000 feet, but one receives many more inches of rain per year. Which of the following best explains the difference in precipitation?
Stampede Pass and Bend both have elevations between 3500-4000 feet, but one receives many more inches of rain per year.
Stampede Pass dumps into Interstate 90 after crossing the Yakima River (DP15), which you will then follow many miles south into the Cle Elum Valley. In 1881, the history of Stampede Pass began. The route builders' abrupt head-long surge gave the pass its original name, "Garfield Pass," after the 20th U.S. president. An assistant engineer working for the Northern Pacific Railway later changed the name to "Stampede." BNSF Railway now owns Stampede Pass. The corridor is mostly utilized for moving empty rail cars in a single direction because it is predominantly single-tracked, has short tunnel clearances, is not signaled, and has severe gradients.

what upper-air patterns would support a forecast for severe thunderstorms or tornadoes
1. Ajet stream: The presence of a strong jet stream in the upper atmosphere can create wind shear, which is a change in wind speed and/or direction with height. This can create an environment that is conducive to the formation of thunderstorms and tornadoes.
2. A deep trough: A deep trough in the upper atmosphere can create instability in the lower atmosphere by allowing cool, dry air to move in at the surface while warm, moist air rises. This can create a favorable environment for thunderstorm development.
3. High moisture content: High moisture content in the upper atmosphere can lead to the development of thunderstorms by providing the necessary moisture for cloud formation and storm development.
4. An area of low pressure: An area of low pressure in the upper atmosphere can create a convergence zone where warm, moist air from the south meets cooler, drier air from the north. This can create an unstable atmosphere that is conducive to thunderstorm development and tornado formation.
5. Wind shear: As mentioned earlier, wind shear is a change in wind speed and/or direction with height. In the presence of wind shear, thunderstorms can become more organized and develop into supercell thunderstorms, which are more likely to produce tornadoes.
These are just some of the upper-air patterns that could support a forecast for severe thunderstorms or tornadoes. Other factors, such as surface temperatures, humidity, and atmospheric stability, also play a role in thunderstorm and tornado development and should be considered in any severe weather forecast.

How is the histogram for the stickers from the small package distributed? Positively skewed (high at the left and tail to the right) Normally distributed Negatively skewed (high at the right and tail to the left)
The histogram for the stickers from the small package is positively skewed (high at the left and tail to the right).
In a positively skewed distribution, the majority of the data values are concentrated on the left side of the histogram, while the tail extends towards the right. This means that there are relatively more occurrences of lower values or fewer stickers in this case.
In the context of the small package of stickers, a positively skewed histogram indicates that there are fewer instances of larger quantities of stickers and more instances of smaller quantities. The distribution is skewed towards the lower end, suggesting that the majority of the stickers fall into the lower quantity range.
This type of skewness commonly occurs in distributions where there is a natural upper limit or constraint that restricts the occurrence of larger values. For example, if the small package contains a fixed number of stickers, it is unlikely to have a large number of stickers.
It's important to note that the shape of the histogram is determined by the underlying distribution of the data. If the data were normally distributed, the histogram would display a bell-shaped curve. In the case of a negatively skewed distribution, the histogram would be high at the right and have a tail extending towards the left. However, for the given scenario of sticker quantities in a small package, the histogram is positively skewed.

Communities with low evenness will have rank-abundance curves _______
A) that are very steep.
B) that are very shallow.
C) that are flat.
D) that are 1:1.
Communities with low evenness will have rank-abundance curves that are very steep. The correct answer is option a.
Rank-abundance curves depict the relative abundance of different species within a community. Evenness refers to the equitable distribution of individuals among species.
In communities with low evenness, there is a significant disparity in the abundance of different species, meaning that a few species dominate while others are less represented. This results in a steep rank-abundance curve, where a small number of species have high abundance (rank) while the majority of species have low abundance.
This steep decline in abundance as rank increases indicates the uneven distribution of individuals among species in the community.

Iguazu Falls are one of the highest waterfalls in the world and the biggest waterfall system in the world. The amount of water that falls down these waterfalls is enormous, and that combined with the height gives the water a lot of power. The water is carrying huge amounts of pebbles, rocks, the debris of all sorts and sizes, and they combined with the water manage to erode the bedrock.
As the water carries all of the material with it, it scratches the surface of the bedrock, and as it does it gradually makes the surface of the bedrock smooth. At the waterfalls themselves, the power with which the water and the material it carries are much bigger so they manage to create a very deep caldron-like hole in the bedrock below the waterfall, and plus smoothens its surface.

Select one: a. burning fossil fuels : release of CO2, a potent greenhouse gas b. strip mining : oil spills killing wildlife c. surface mining : acid mine drainage polluting rivers d. mountaintop removal mining : mine tailings and debris filling valleys e. coal-burning electric plants : acid deposition destroying forests Incorrect
Among these activities, b) strip mining : oil spills killing wildlife is mismatched with its environmental consequence.
Strip mining, also known as overburden removal, is the method of extracting a seam of minerals by first removing a broad strip of the surrounding rock and soil (the overburden). The most typical uses are for mining lignite and coal (brown coal). Only ore bodies that are mainly horizontal and/or reasonably close to the surface make strip mining feasible. Some of the biggest equipment on the planet is used in this kind of mining, such as bucket-wheel excavators, which can move up to 12,000 cubic meters of earth per hour.
Strip mining has two different variations. Region stripping, which is more frequently employed to recover deposits over a wide area on relatively flat terrain. The overburden is deposited in the excavation created by the previous long strip as it is excavated.
In hilly terrain, where the outcrop of the mineral typically follows the contour of the ground, contour mining entails removing the overburden from above the mineral seam close to an outcrop. In order to get more of the material, contour stripping is frequently followed by auger mining into the slope. Terraces in mountain faces are frequently left behind using this technique.

The reason why surface winds behave differently from winds aloft is best explained by FRICTION. A force called friction prevents a sliding object from moving. It is also the resistance of one object to motion as compared to another. It is not a basic force like electromagnetism or gravity.
