Oymyakon is the earth's coldest continually inhabited settlement. It is a small of about 500 people situated in Russia.
What are the features in Oymyakon ?The Sakha area of Russia's Oymyakon, a small community of 500 residents, is famous for being the world's coldest continuously inhabited location. It is difficult to get to, and is about 20 miles northwest of Tomtor on the Kolyma Highway.
When a Soviet scientist braved a chilly -96° Fahrenheit in 1924 in Oymyakon, which is located in what is known as Stalin's Death Ring, it set the record for the coldest temperature ever recorded by a continually inhabited settlement.
In 1924, temperatures hit a record low of -96.16 degrees Fahrenheit (71.2 degrees Celsius). The memorial commemorating the day in 1924 is seen in the town plaza.
It was first inhabited in the 1920s and is located near to the Arctic Circle, north of the Sea of Okhotsk. Prior to that, it served as a well-liked rest area for winter herders who frequently stopped by a thermal spring for their reindeer.

Which environment usually experiences the most extreme seasonal variations?
A. tropical forest
B. The open ocean.
C. Boreal Forest
D. Tidal pool.
Answer:
Tidal Pools
Explanation:
Tidal pools usually experience the most extreme seasonal variations. They are located in the intertidal zone, which is the area of the shore that is covered and uncovered by the tides. As a result, the organisms that live in tidal pools are exposed to extreme variations in temperature, salinity, and other environmental factors as the tides come in and go out. This can make life challenging for the organisms that live there and can lead to high levels of seasonal variability in the tidal pool ecosystem.

Injecting hot fudge into ice cream and causing it to melt is an appropriate analogy for melting due to an addition of volatiles.
The process of injecting hot fudge into ice cream and causing it to melt is a good analogy for melting due to an addition of volatiles. In this analogy, the hot fudge represents the volatiles, which are substances like water vapor, carbon dioxide, and sulfur dioxide that can be released from solid rock and mix with the surrounding mantle material. Just as the hot fudge melts the ice cream by adding heat, volatiles can lower the melting point of rocks in the mantle by weakening the bonds between minerals and allowing them to melt at lower temperatures. This can lead to the formation of magma, which can then rise to the surface and erupt as a volcanic eruption. Melting due to an addition of volatiles is a common cause of magma melt, particularly in subduction zones where water is released from the subducting plate and mixes with the surrounding mantle material. Understanding the role of volatiles in the formation of magma is an important aspect of studying volcanic activity and can help scientists to better predict and mitigate volcanic hazards.

What gas has a higher concentration in the stratosphere than in the troposphere?
The stratosphere has significantly greater ozone concentrations than the troposphere, while the troposphere has far higher amounts of water.
The quantities of ozone and water vapour in the stratosphere and troposphere differ significantly from one another. At 90% of ozone may be found in the stratosphere, which starts at an altitude of 50 kilo-meters (31 miles) and rises to a height of 10-16 kilometres (6-10 miles) above the surface of the Earth. The term "ozone layer" refers to the stratospheric area with the highest ozone content.
The two most common gases are nitrogen (78%) and oxygen (21%), with argon (.9%) and a trace amount of hydrogen ozone (a kind of oxygen) making up the remaining 1% of all gases. The troposphere's temperature and water vapour concentration drop with altitude.

explain how subduction leads to volcanic activity.
Subduction leads to volcanic activity because when an oceanic plate is forced beneath a continental plate, the heat and pressure cause melting and the formation of magma.
Subduction occurs when one tectonic plate is forced beneath another tectonic plate. When this happens, the plate that is being forced down (usually an oceanic plate) begins to sink into the Earth's mantle, which is hotter and more fluid than the crust. As the oceanic plate sinks deeper into the mantle, it experiences increasing temperatures and pressures. These conditions cause the plate to begin to melt, and the magma that forms begins to rise back up towards the surface. If the magma reaches the surface, it can erupt as a volcano. This type of volcanic activity is common in areas where subduction is occurring, such as the Ring of Fire in the Pacific Ocean. The magma that is formed during subduction is typically rich in volatile elements, such as water and carbon dioxide, which can make the eruptions more explosive. Overall, subduction is a major cause of volcanic activity around the world, and understanding the processes that occur during subduction is key to predicting and mitigating volcanic hazards.

what is the cause for the slow movement of reference marks, such as the celestial poles and equator, to move across the sky?
The slow movement of celestial poles and equator across the sky is caused by the Earth's rotation and the precession of its axis.
The Earth rotates on its axis once every 24 hours, causing the entire celestial sphere to appear to rotate around us. This rotation causes the stars and other celestial objects to appear to move across the sky. The axis of rotation of the Earth is not fixed in space, but it slowly moves like a spinning top that wobbles. This movement of the Earth's axis is called precession, and it causes the celestial poles and equator to shift their position across the sky over a period of thousands of years.
Precession is caused by a combination of the gravitational forces of the Sun and Moon on the Earth's equatorial bulge, as well as the gravitational effects of other planets in the solar system. As the Earth spins on its axis, it experiences a torque that causes the axis to slowly wobble around a circle over a period of about 26,000 years.
As a result of this slow precession, the celestial poles and equator slowly move across the sky, taking thousands of years to complete a full circle. This means that over time, the positions of the stars and constellations we see in the night sky also slowly shift.

why can there be no breaks in the thin-layer surface of a tlc plate?
Thin-layer chromatography (TLC) plates are used to separate and analyze different compounds in a mixture based on their differing affinities for a stationary phase (usually a silica gel or alumina) and a mobile phase (usually a solvent).
TLChromatography plates are made of a thin layer of the stationary phase coated onto a flat support, such as a glass or plastic plate. It is important that the surface of the TLC plate is continuous and without breaks or scratches because any damage to the surface can disrupt the even distribution of the stationary phase, leading to irregularities in the separation and reduced accuracy of the analysis. A break or scratch in the surface of the TLC plate can cause the stationary phase to be disrupted or removed in that area, which can affect the separation and cause the compounds to migrate differently than they would on an intact surface. This can lead to inaccurate results, and it can make it difficult to compare the TLC plate to other plates or to obtain reproducible results. Therefore, it is important to handle and store TLC plates carefully and to avoid any damage to their surfaces.

From its beginnings in the 1860s until the Great Depression of the 1930s, the US labor movement faced strong opposition from the government. In the lesson, we discussed how government officials sided with business owners in labor disputes. Some state governments passed laws making strikes illegal. State and federal governments sent troops to break up strikes. Finally, no federal labor laws were passed until the second half of the 1930s.
Why do you think government officials (and the public in general) were opposed to labor unions in the beginning? Why do you think things began to change during the hard economic times of the 1930s?
Answer:
Government officials, and the public in general, were initially opposed to labor unions because they believed them to be a threat to the existing economic power structure. They feared that labor unions would give too much power to workers, and that this could disrupt the balance of power between employers, workers, and government.
Things began to change during the hard economic times of the 1930s because people began to understand the need for workers to have more rights and protections. With the rising unemployment and poverty caused by the Depression, many saw the potential benefits of labor unions when it came to negotiating better wages and working conditions for workers. This shift in public opinion eventually led to the passage of labor laws in the second half of the 1930s.
