The substances are transported to the Arctic in the atmosphere by ocean currents, and also by rivers and ice in the Arctic. These are the most important means of transport, but pollutants carried by animals which move between the polar areas may also have some significance.
How do ocean currents pollute remote locations?
Because ocean currents flow slowly, it may take decades for contaminants from heavily industrialised and populated places to reach the ocean. The ocean currents carry pollutants that are soluble in water and are dumped directly into the ocean or fall as rain into the ocean. The degree to which the contaminants are soluble in water will determine whether they bind to particles or sink to the seafloor. Such places might develop into what is known as sinks, or repositories for pollutants.
The layers in the water and the current systems govern the maritime transit of contaminants to the Arctic. It might take years for toxins to travel through the ocean and reach the Arctic. Then, they may stay under the water for a few years to several millennia.
Some radioactive compounds may be carried by ocean currents over great distances depending on how they behave in the marine environment.
Measures taken to stop pollutants from reaching the environment are delayed by the slow movement of the ocean currents towards the pole.

according to scientific consensus, what is driving the majority of climate change in the modern world?
Global warming is the reason for climate change in the modern world.
What is climate change?
A long-term change in the typical weather patterns that have characterised local, regional, and global climates on Earth is called climate change. The phrase is synonymous with a wide variety of observed outcomes resulting from these changes.
Global warming is the gradual warming of the Earth's surface that has been seen since the pre-industrial era (between 1850 and 1900) and is attributed to human activity, particularly the burning of fossil fuels, which raises the levels of heat-trapping greenhouse gases in the atmosphere. This phrase should not be used in place of "climate change."
Human activities are thought to have contributed to an increase in Earth's average global temperature of about 1 degree Celsius (1.8 degrees Fahrenheit) since the pre-industrial era. This temperature increase is currently happening at a rate of more than 0.2 degrees Celsius (0.36 degrees Fahrenheit) per decade. Without a doubt, human activity since the 1950s has contributed to the current warming trend, which has been accelerating at an unheard-of rate for millennia.

Answer:The assertion made by Bill McKibben is bogus. There is no proof to recommend that the Earth can't uphold human existence any more. As a matter of fact, there is proof to recommend that the Earth can uphold human existence for the majority more years.
Explanation:The principal motivation behind why the Earth can't uphold human existence any more is a result of the rising populace. As the populace builds, how much assets diminishes. This ultimately prompts what is going on where the Earth can't uphold the populace. Nonetheless, this isn't what is happening that we are at present in.

at what depth does metamorphism start in the earth's crust if the surface is 25 degrees celsius, the geothermal gradient is 25c/km, and metamorphism starts at 200c?
Temperature and pressure can become so extreme at a particular depth that they can change the chemical makeup, texture, or mineralogy of rocks. The transformation of rocks is known as metamorphism.
At a depth of 10 to 30 km, the middle and lower crust produces the majority of metamorphic rocks. The rate at which the temperature of the Earth rises with depth is known as the geothermal gradient. It suggests that the Earth's surface is receiving heat from the planet's warm center. For every kilometer of depth, the temperature rises by about 25°C on average. Such magma bodies heat the surrounding rock to a temperature of about 1000 °C, causing contact metamorphism (Figure 7.19). In the absence of directed pressure, this occurs at very shallow depths, hence the resulting rock typically does not foliate. Tectonic forces, like the collision of two continental masses, frequently cause compressional stresses in the rocks, which cause the differential stress. Consequently, the cores of fold-and-thrust mountain belts or eroded mountain ranges are where regionally metamorphosed rocks are found. As far as metamorphic processes go, burial metamorphism occurs at pressures and temperatures that are relatively low (up to 300 °C).

Consequently, the cores of fold-and-thrust mountain belts or eroded mountain ranges are where regionally metamorphosed rocks are found.

florian discovers a rock that is broken into pieces. each piece has several bands.which type of rock does florian predict these pieces will change into when subjected to heat and pressure?igneousmagmametamorphicsedimentary
Metamorphic rocks will change when subjected to heat and pressure
What are Metamorphic rocks?
Although they began as a different kind of rock, metamorphic rocks have undergone significant alteration from their igneous, sedimentary, or previous metamorphic forms. Metamorphic rocks are created when rocks are exposed to extreme temperatures, high pressures, hot mineral-rich fluids, or, more frequently, some combination of these conditions. These kinds of situations can be found deep inside the Earth or where tectonic plates collide.
The process of metamorphism changes the rocks into denser, more compact rocks rather than melting them. Either by the rearranging of mineral constituents or through chemical reactions with fluids that enter the rocks, new minerals are produced. Even rocks that have already undergone metamorphosis might undergo changes due to pressure or temperature. Rocks subject to metamorphism are frequently crumpled, smeared, and compressed. Metamorphic rocks do not get hot enough to melt because if they did, they would turn into igneous rocks.
The metamorphic rocks phyllite, schist, gneiss, quartzite, and marble are frequently encountered.

Contact between sedimentary strata that are noticeably older than each other or between sedimentary rocks and older, eroded igneous or metamorphic rocks is known as an unconformity. Gaps in the geologic record, or times when no rocks exist, are represented as unconformities.
Unconformities can occur for two reasons: either older rocks were eroded before being covered by younger sediment, or sediment deposition ceased for a long period of time. An unconformity does not reflect a particular moment in time. According to how long erosive processes continued or how long deposition stopped.

typhoon intensity of landfalling storms in the western pacific near asia appears to be increasing, what is the main reason?
Typhoon intensity of landfalling storms in the western pacific near Asia appears to be increasing because water vapor in the atmosphere rises.
A mature tropical cyclone, or typhoon, forms in the Northern Hemisphere between 180° and 100°E. The Northwestern Pacific Basin is the most active tropical cyclone basin on Earth, producing over a third of all tropical storms that occur annually.
The greatest sustained wind speed of a typhoon serves as a measure of its strength, but the damage wrought by its strong winds, storm surges, heavy rains, and floods increases proportionally, so that a 15% increase in intensity results in a 50% increase in destructive power.
Storm precipitation is growing as a result of increased heat, water, and rising sea surface temperatures. This could also give storm winds more fuel. The maximum surface wind speed or the lowest sea level pressure are used to determine the strength of a storm. Many of the factors that can lead to more intense storms are impacted by climate change. By increasing the meridional (or poleward) temperature gradient and the amount of additional latent heat available in warmer air, it increases the amount of potential energy that is available.

describe the airflow around a low-pressure center (cyclone) and a high-pressure center (anticyclone) and the weather associated with each.
A cyclone is a large scale air mass that rotates around a low-pressure center. The rotation is caused by the Coriolis force, which is stronger at the poles than at the equator. The cyclone's rotational energy is transferred to the atmosphere, which causes the air to rise. This rising air causes the pressure at the center of the cyclone to drop, which causes the wind to speed up. The cyclone's rotational energy is also transferred to the water, which causes the waves to grow larger. The cyclone's wind and waves can cause extensive damage to coastal areas.
The anticyclone is the opposite of the cyclone. It is a large scale air mass that rotates around a high-pressure center. The anticyclone's rotational energy is transferred to the atmosphere, which causes the air to sink. This sinking air causes the pressure at the center of the anticyclone to rise, which causes the wind to speed up. The anticyclone's rotational energy is also transferred to the water, which causes the waves to grow smaller. The anticyclone's wind and waves can cause extensive damage to coastal areas.
