Emissions of pollutants into the air can result in changes to the climate. These pollutants, including greenhouse gases, are often referred to as climate forcers. Ozone in the atmosphere warms the climate.
A pollutant or novel entity is a substance or electricity introduced into the environment that has undesired results, or adversely affects the usefulness of a useful resource. those can be each certainly forming or anthropogenic in the foundation.
A pollutant is a substance this is found in concentrations which could damage organisms (humans, plants and animals) or exceed an environmental high-quality wellknown. The term is often used synonymously with contaminants.
Air pollution, Noise pollutants, Water pollution, and Soil pollution. other styles of pollutants are thermal pollutants, light pollutants, and radioactive pollution. Examples are particulates, carbon monoxide, nitrogen oxide, and sulfur oxide. Secondary air pollution: pollutants that might be formed in the lower ecosystem through chemical reactions. the 2 examples are ozone and secondary organic aerosol (haze).

which of these are the two major sources of nitrate pollution in rivers?
A) the burning of fossil fuels by factories and cars
B) animal wastes and the burning of fossil fuels by cars
C) animal wastes and fertilizers
D) fertilizer runoff and the burning of fossil fuels by cars
E) animal wastes and the burning of fossil fuels by factories
The two major sources of nitrate pollution in rivers are animal wastes and fertilizers. The Option C is correct.
What is Nitrate Pollution in Rivers?In a river, a nitrate pollution are caused by a variety of sources, in which some are natural and some man-made. These nitrates are naturally found in rocks, soil, as well as living organisms such as algae and bacteria.
However, nitrogen are also added to the environment when fertilizers are used on lawns and farmland and these fertilizers contain nitrates which are then washed into streams by rainwater or melting snow.

what might happen to a losing stream as the water passes from flowing over hard, impermeable rocks to flowing over more permeable rocks?
In a losing stream, if the water passes from flowing over hard and impermeable rocks to flowing over more permeable rocks, then, such steam will lose more water to the subsurface and might disappear.
What is the feature of losing stream?In geography, a losing stream is also called a disappearing stream, influent stream or sinking river, which is a stream that loses water as it flows downstream.
The water from this channel infiltrates into the ground recharging the local groundwater because the water table is below the bottom of the stream channel. They are more common in arid areas due to the climate which results in huge amounts of water evaporating from the river generally towards the mouth.

what is the ultimate source of new variation? does a change in environment cause to new trait to be generated?
New variety arises through mutations. Natural selection merely modifies the amount of variety already existing in the population; it does not produce new features. The development of new adaptive characteristics results from the recurrent two-step interplay of these processes.
What are Mutations?Generally, Any change in the DNA sequence of a cell. Mutations may be caused by mistakes during cell division, or they may be caused by exposure to DNA-damaging agents in the environment.
In conclusion, The origin of new variations may be traced back to mutations. Natural selection does not produce novel features; rather, it only modifies the amount of existing variation that is present in a population.
The development of unique adaptive characteristics is caused by the repetitive interplay of these processes, which takes place in two stages.

Which of the following rocks has the highest permeability?
a. an unfractured shale
b. a cemented sandstones
c. an uncemented sandstone
d. all of these rocks have approximately the same permeability
An uncemented sandstone has the highest permeability. (Option C)
What is a sandstone ?Sand-sized silicate granules make up the majority of the clastic sedimentary rock known as sandstone. About 20–25% of all sedimentary rocks are sandstones. Because quartz and feldspar are the minerals that resist weathering the most at the Earth's surface, they make up the majority of sandstone. Because they are the minerals that are most resistant to weathering processes at the Earth's surface, quartz or feldspar (both silicates) make up the majority of sandstone.
In conclusion, sandstones are created by the cementing of sand grains. Sandstones typically have a rough, grainy texture similar to sandpaper.

The annual temperature range at most latitudes in the southern hemisphere is much smaller than in the northern hemisphere. This is due to the fact that:_____.
a. rainfall and cloudiness are greater in the southern hemisphere
b. there is more mountainous area in the southern hemisphere
c. there is less desert area in the southern hemisphere
d. summer temperatures that are similar to an inland place at the same latitude
As the annual temperature range at most latitudes in the southern hemisphere is much smaller than in the northern hemisphere, this is due to the fact that there is a greater percentage of ocean water surface in the Southern Hemisphere. The Option E is correct.
What is an annual temperature range?In geography, an annual temperature range means the difference between the hottest and coldest months, by taking monthly mean of temperatures in each case.

when pressure is applied to a pile of sediments, the grains will pack together more tightly, taking up less volume. water, however, simply stores the pressure. why?
When pressure is applied to a pile of sediments, the grains will pack together more tightly, taking up less volume. water, however, simply stores the pressure this is because water is nearly incompressible.
What is water?Generally, Water is almost incapable of being compressed, particularly when kept under typical circumstances.
If you place a straw inside of a sandwich bag and then fill the bag with water, when you squeeze the bag, the water won't be compressed as it would if you only squeezed the bag. Instead, it will fly out of the straw.
If you apply pressure to a pile of sediments, the grains will pack together more tightly, resulting in a reduction in the volume that they occupy. Water, on the other hand, just stores the pressure; this is due to the fact that water is almost impossible to compress.

A. Increased availability of food
B. Decreased resistance to parasites
C. Increased competition with carnivores
D. Decreased number of primary producers
Increased availability of food environmental factors would have most likely led to the change in the harbor seat population size from 1980-1990. The correct option is B.
How is food availability correlated with population growth?As the population grows, so does the demand for food, which usually necessitates the use of more arable land and water.
Plants are the primary source of food for people living in overcrowded countries because they cannot afford the 90% energy loss that occurs when plants are fed to animals. At the herbivore level, the same amount of grain can support ten times as many people as at the carnivore level.
Thus, the ideal selection is option B.
