how is air pollution transported? what natural processes do scientists need to consider when studying air pollution?

Answers

Answer 1

Air quality is affected by natural processes. Pollutants can be transported by wind from their source to distant locations.

How does air pollution get around?The effects of natural processes on air quality. Pollutants can be transported by wind from their source to distant regions. Pollutants can be removed from the atmosphere by precipitation. The transport of pollutants away from their sources and the emergence of secondary pollutants are predicted by scientists using computational models.Transport, dispersion, and deposition are the three processes that cause contaminants to move around in the atmosphere. Transport is movement brought on by a wind flow over time. Local turbulence, or motions that last for a shorter period of time than the transport average, leads to dispersion.Over the last ten years, various field and modelling studies have been used to study the intricacies of the transport and dispersion of airborne contaminants related to vehicle emissions.

What factor causes the northwest corner of the us to be so humid when the general area surrounding it is semi arid?

Answers

Humidity - The amount of water vapour in the air is known as humidity. The humidity will be high if there is a lot of water vapour in the atmosphere. It feels wetter outside as the humidity rises. Humidity is typically described as relative humidity on weather reports.

In the summer, the dewpoint temperatures are frequently higher near the east coast than they are along the west coast because warm air can contain more moisture than chilly air, making it feel more humid.

The mountains in the east keep humid air from accessing most of the eastern US, which is another reason why the northwestern region is much more humid than the eastern region.

Why are seismologists interested in the possibility of the two faults being connected together?.

Answers

The seismologists are interested in the possibility of the two faults being connected because it might cause an earthquake.

What is a fault?

A fault is an area of fractures or a fracture among two blocks of rock. Faults enable the blocks to keep moving relative to each other. Moving blocks can collide with each other. This collision can press the rocks, in other words, the faults that are connected result in earthquakes from movement in the ground and it is the potential to be larger based on the production stress of the collisions.

There are three fundamental types of faulting.

Normal: Concerning the lower block, the upper block moves downward.

Reverse: The upper block advances toward the lower block. It is responsible for the formation of some of the world's highest mountain ranges, as well as the Himalayas and the Rocky Mountains.

Strike-slip: Both blocks slide across one another horizontally. That is, if you were standing close to the fault trace and looked across it, you will further realize a far edge moving to the right or left.

These source regions influence the weather in North America.

1 Maritime air masses originate over water. This is why they are usually humid.

2. Polar and Arctic air masses are cold. This is due to their location at higher latitudes. We know in the troposphere, there exists a negative lapse rate. There is a decrease in temperature with altitude.

3. Maritime and tropical air masses are warm and humid. This is because these are usually formed in tropical and sub-tropical areas over water bodies. This leads to evaporation which forms water vapour. Thus the presence of water vapour makes the air mass humid.

4. Continental and tropical air masses are dry and warm. These originate over land and hence lack moisture and thus are warm and dry.

5. Polar and Arctic air masses originate at higher latitudes. This is the reason that they are so cold. The Arctic air mass is colder than the polar air mass.
