One of the six major air pollutants tracked by the u.s. epa in 2001, which is primarily a result of poor farming practices in the midwestern united states is nitrogen oxides.
What is air pollutionAir pollution is the presence of airborne substances in the air, which harm the health of living things and the environment, or cause damage to the environment or man-made objects.
There are several types of air pollutants, including particulates, volatile organic compounds, and radioactive materials. Many examples of air pollution occur in urban areas where vehicles, factories, and smoke-producing sources create air pollution. Another example of air pollution occurs in rural areas.
Examples of air pollution in rural areas can be caused by soil erosion due to rapid population growth; lack of clean drinking water; use of pesticides and insecticides; and disposal of animal manure and garbage. Some examples of pollution can also occur outdoors and involve the emission of polluting aerosols and emissions from factories, vehicle exhaust, and other types of combustion sources.
The devastating impact of air pollution on human health has become more than just a concern for environmental advocates, it is now recognized that it contributes to several types of diseases such as heart disease, asthma, and chronic cough and lung irritation. This disease is usually exacerbated by pollution, both outside and indoors.

the canadian shield surrounds most of which body of water?
a. St. Lawrence River
b. Big lake
c. Hudson Bay
d. Athabasca Lake.
e. All Answers are correct
Answer:
hudson bay
Explanation:
The Canadian shield surrounds most of Hudson Bay by forming a horseshoe-shaped border around it. Hence, the correct answer is option C.
The greatest of Canada's six physical areas is the Canadian Shield and it surrounds most of Hudson Bay. The majority of it is rock, which millions of years ago was a mountain range. This rock was flattened by the process of erosion, which was carried out by water, ice, glaciers from the Ice Age, and wind.
Rivers, rapids, lakes, and valleys were formed out by the nature's forces over all those millions of years. The granite was extremely near the surface when every bit of erosion had taken place. In actuality, the soil doesn't have a lot of depth.

What is a protista?The Protista are a vastly complex order of eukaryotic creatures, most of which are unicellular. The majority of terrestrial, aquatic, and marine ecosystems contain them in both free-living forms and as parasites of other protists, fungi, plants, and animals. They have a wide variety of morphological features.
Any eukaryotic organism that is not an animal, plant, or fungus is referred to as a protist. The absence of other eukaryotes means that protists do not constitute a natural group, or clade, even though it seems likely that they all descended from a common ancestor.

The later of disturbed rocks may have to be determined by fossils or other clues. Describes the age of 1 rock layer in comparison to another. Determined by looking about rock layers and fossils. Example: the rock lover in the earth is usually older than the one at the top of the mountain because of superposition.
According to their relative position—younger rocks are placed on top of older rocks—relative age dating is used to identify whether a rock layer or the fossils contained within it are older or younger than another.
In order to ascertain the relative age of a layer of sedimentary rock, scientists employ a fundamental concept known as the Law of Superposition. According to the Law of Superposition, a sedimentary rock layer that has not been deformed is older than the layers above it and younger than the layers below it.
Radiometric dating, which considers the ratio of two distinct isotopes in a sample, establishes the age of rocks. Geologists may estimate the age of a material using tools like this thermal ionisation mass spectrometer because radioactive isotopes degrade over a predictable period of time.

Quinn and Quade had to make a model of the Earth's four
main layers using items from around their house. They did not
have to include the lithosphere in their project. The layers had
to accurately represent the density of each layer in relation to
each other. They gathered several items from around the
house. The materials are listed below.

small bouncy ball, marble ball, tennis ball, small iron ball, large
iron ball, slime, thin styrofoam sheet, styrofoam ball,
cardboard, clay, play-dough, icing.
The description on how Quinn and Quade would be able to make the model of the earth has been done below.
How to make the model of the earthQuinn and Quade can use the following materials to make a model of the Earth's four main layers, without including the lithosphere:
The innermost layer, the inner core, can be represented by the small iron ball as it has a high density and is the smallest in size, just like the inner core.
The outer core can be represented by the large iron ball, as it has a slightly lower density than the inner core and is larger in size.
The mantle can be represented by the clay or play-dough, as it has a lower density than the outer core and is less rigid.
The crust can be represented by the cardboard or thin styrofoam sheet, as it has the lowest density of all the layers and is the most rigid.
To represent the density of each layer in relation to each other, they can stack the materials on top of each other in order of increasing density, with the small iron ball at the bottom and the cardboard or thin styrofoam sheet at the top.
Note that the provided materials might not be the best for representation of the Earth layers but with some creativity it can be done.
