Answer:
1. Most common causes---- Mercury, nitrogen and phosphorus, pesticides, dissolved metals (excluding mercury) and PCBs (industrial pollutant)
2. Least common causes---- pH changes , sedimentation and hypoxia.
Explanation:
The most common heavy metals that causes pollution are chromium (Cr), cadmium (Cd), lead (Pb), nickel (Ni), arsenic (As), mercury (Hg), zinc (Zn) and copper (Cu). Nitrogen and phosphorus application pollutes the water due to its leaching nature. The use of pesticides is very common in agriculture that cause more pollution. Pollutant comes from the industries cause water pollution and is responsible for a number of diseases.
mesosphere seems to be very important for the earth atmosphere why
Answer:
mesosphere seems to be very important for the earth atmosphere because It keeps the planet warm and protects us from the harmful radiation of the Sun. It also ensures a healthy balance between oxygen and carbon dioxide so that life can be sustained on the planet.hope it helps. stay safe healthy and happy.Suppose a friend is trying to claim that it is summer when Earth is closest to the Sun and winter when Earth is farthest away. Refute this claim in at least two different ways: (1) with an argument that invokes seasonal differences between the Northern and Southern Hemispheres and (2) with an argument based on the times of year at which Earth actually is closest to and farthest from the Sun. Write out your arguments clearly
Answer:
1) This claim is inaccurate, that there's summer when Earth is closest to the sun and winter when the planet is farthest from the sun.
2) This claim is inaccurate, because Earth is closest to the Sun on January 3-4, when it's Winter in the northern hemisphere and summer in the southern hemisphere. So why it's not Summer in both hemispheres, since the planet is closest to the Sun.
Thus, summer and winter aren't caused by the varying distance between the world and therefore the sun.
Explanation:
1)
If it's so then why seasons are Opposite in two hemispheres. it's summer within the northern hemisphere when it's winter within the southern hemisphere. Alternatively, it's Winter within the northern hemisphere, while it's summer within the southern hemisphere.
If the seasons occurred because of the gap from, sun, then it should be the same season in both the hemispheres, when Earth is farthest and closest from the Sun. Why are seasons different in both hemispheres. So this claim is inaccurate.
2)
Earth is farthest from the Sun on the Fourth of July, which is really summer in the northern hemisphere and winter in the southern hemisphere. So why is it not winter in both the hemispheres, since the planet is Farthest from the Sun.
Here the earth's orbit isn't an ideal circle. it's elliptical, or slightly oval-shaped.

why does the torrid zone receives maximum amount of heat
The sun rays directly comes and faces the area between the tropic of Cancer and tropic of Capricorn. It is the torrid zone. Hence, the torrid zone receives maximum amount of heat.
Seawater is highly saline, which means it contains large amounts of dissolved salt. When seawater freezes and icebergs
form, the water in the iceberg doesn't take the salt with it. What effect will this phenomenon have on the concentration of
salt in the water around the iceberg?
Answer:
Because the amount of liquid water decreases and the amount of dissolved salt remains constant, the concentration of salt in the liquid water around the iceberg will increase.

Answer:
The correct answer is Option b (The theory...........occur today).
Explanation:
The hypothesis that throughout the previous world more or less the same scientific processes, as well as methods operating throughout the existence that has ever been functioned, could be determined as Uniformitarianism.While it may be applicable in whatsoever field, it would be an essential pillar for the establishment of geological technology.The other alternatives are not related to the given scenario.

How would you be able to immediately tell whether a shale parent rock had been subjected to either intermediate-grade contact metamorphism or intermediate-grade mountain belt (regional) metamorphism?
Answer:
On the basis of heat and pressure the rock undergoes transformation.
Explanation:
The contact metamorphism occurs when magma comes into contact with the already existing body of rocks. Regional metamorphism occurs in wider areas of earths crust. It occurs in areas where the rocks have undergone deformation at time of orogenetic events. Metamorphic grades refers to the changes in the processing of rocks form low to high grade. The shale rocks are metamorphized under intense heat and pressure to form slate thereby increase in the grade quality. If the rocks are subjected to contact metamorphism then slate is formed and if its regional metamorphism then phyllite, then schist, and finally, gneiss are formed.sumulat ng isang iskrip ng napapanahong isyu sa ating bansa

explain in your own words the three mechanisms that cause air to be displaced into the atmosphere
Answer:
orographic, convectional and cyclonic lifting
Explanation:
orographic is when air mass is forced from lower to higher elevation. convectional lifting is warming up parcel of air at the surface of the earth by conduction. cyclonic lifting is lifting of air mass due to differences in pressure this is when cold air meets warm air.
The three mechanisms that cause air to be displaced into the atmosphere are orographic, convectional, and cyclonic lifting. This is further explained below.
What is air displacement?Generally, Air displacement is simply defined as plethysmography a well-known and scientifically confirmed method of measuring human body composition.

Please help me out with this question given below:
Why is erosion considered a slow process?
Explanation:
Weathering has deteriorated and broken up the sandstone, making it ready for destruction. Erosion occurs when ice, moisture, wind, or gravity take up and transport rocks and materials to a new location. They can't transport as much sediments if they slow down. Rock formations are where the sediment is dumped or deposited.

g Although the Humid Continental and Marine climates are at similar latitudes, they have very different annual temperature ranges. What factor is responsible this difference
Answer:
nearness to sea or ocean
Explanation:
Presence of water body is the factor that is responsible for the difference in annual temperature although the Humid Continental and Marine climates are present at the same latitudes. Marine climates are located near the water bodies such as ocean or sea while on the other hand, Humid Continental climates are located farther from the water bodies such as sea or ocean.

Answer:
Temperate Forests ⇒ Trees that lose leaves in fall
Here trees change their behavior every season to survive the cold. Their most distinguishing feature is how their leaves change color in response to the season and in the fall, they shed their leaves.
Boreal Forests ⇒ Evergreen
Boreal forests are the largest forest areas in the world. Areas tey cover are in Canada, Russia and Alaska and on account of being able to survive the cold weather, they are evergreen.
Rain Forest ⇒ Giant Vines
Rain forests have a lot of canopy like trees which blocks sunlight for other plants. These plants respond by using large vines to reach sunlight.
Chaparral ⇒ Grasses and Shrubs
These have the shortest and least numerous trees of the bunch. There are also a lot of grasses and shrubs. You will find these in the California.

The half-life of Carbon-14 is 5, 730 years. you find a sample where 1.5625% of the original Carbon-14 still remains how old is that sample ?
Answer:
The sample is about 34380 years old.
Explanation:
The amount of Carbon-14 mass diminishes exponentially in time, whose model is described below:
[tex]\frac{m(t)}{m_{o}} = e^{-\frac{t}{\tau} }[/tex] (1)
[tex]\tau = \frac{t_{1/2}}{\ln 2}[/tex] (2)
Where:
[tex]m_{o}[/tex] - Initial mass, in grams.
[tex]m(t)[/tex] - Current mass, in grams.
[tex]t[/tex] - Time, in years.
[tex]\tau[/tex] - Time constant, in years.
[tex]t_{1/2}[/tex] - Half-life, in years.
If we know that [tex]\frac{m(t)}{m_{o}} = \frac{1.5625}{100}[/tex] and [tex]t_{1/2} = 5730\,yr[/tex], then the age of the sample is:
[tex]\tau = \frac{5730\,yr}{\ln 2}[/tex]
[tex]\tau = 8266.643\,yr[/tex]
[tex]t = - \tau \cdot \ln \frac{m(t)}{m_{o}}[/tex]
[tex]t = - (8266.643\,yr)\cdot \ln \frac{1.5625}{100}[/tex]
[tex]t \approx 34380.002\,yr[/tex]
The sample is about 34380 years old.
