How are van allen belts formed? high-energy particles from the sun get trapped in earth’s magnetic field. metals in earth’s core sink and rise, producing a circular movement of the metals. particles in solar wind travel along lines of earth’s magnetic field and collide with gas atoms. material from the surface of the sun erupts and forms a loop due to the sun’s magnetic field.

High temperatures and solar wind in the inner planets allowed most of the volatiles to be driven off the terrestrial planets, but not the Jovian planets.

Terrestrial planets have higher density than Jovian planets.Jovian planets are mostly gas and liquid, terrestrial planets are solid and rocky.Jovian planets are almost gaseous and they are larger than terrestrial planets.

Planetary theory is a theory about the formation of planets. According to the planetary system hypothesis, when a planetary system forms, there will be a protoplanetary disk with material from the nebula from which the planetary system originates. This material is gradually assembled by gravity to form small pieces.

John Wesley Powell, in his Report on the Lands of the Arid Regions of the United States (1878), famously stated that massive cooperation under government control was the only way farming would succeed on the Great Plains.

John Wesley Powell, (born March 24, 1834, Mount Morris, New York, U.S.—died September 23, 1902, Haven, Maine), American explorer, geologist, and ethnologist, best known for his exploration of the upper portion of the Colorado River and the Grand Canyon.

In 1878, Powell published his Report on the Lands of the Arid Region, which laid out a concrete strategy for settling the West without fighting over scarce water. Powell wanted to stall the waves of homesteaders moving across the plains and mountains.

Instead, he wanted to plan settlement based in part on the cooperative model practiced in Utah by Mormon settlers, who tapped mountain snowmelt and the streams, lakes and rivers it created with irrigation ditches leading to crops. Powell wanted to organize settlements around water and watersheds, which would force water users to conserve the scarce resource, because overuse or pollution would hurt everyone in the watershed.

Powell believed this arrangement would also make communities better prepared to deal with attempts to usurp their water.

Therefore, we can conclude that the correct option is C.

Silk was the most desired commodity in long-distance trade

Silk is a natural protein fabric that may be woven into textiles in some forms. Silk is a protein fiber consisting primarily of fibroin that is produced by certain insect larvae to construct cocoons. The most well-known silk is made from the cocoons of captive-reared mulberry silkworm larvae Bombyx mori.

Silk manufacturing began in China during the Neolithic period (Yangshao culture, 4th millennium BC). Silk remained restricted to China until the Silk Road was established sometime around the second millennium BC. For another thousand years, China maintained a virtual monopoly on silk production.

Silk fabric was invented in Ancient China and has since played an important role in their culture and economy.

Because lenses act like a prism to separate the colours of the spectrum, they produce a troublesome effect known as Chromatic abberation.

Chromatic aberration (CA), also known as chromatic distortion and spherochromatism in optics, is when a lens fails to bring all colours into focus at the same location. It results from dispersion because the lens elements' refractive indices change depending on the light's wavelength.

Most transparent materials lose refractive index as wavelength increases. Because a lens's refractive index determines its focal length, variations in that index have an impact on focusing. Chromatic aberration appears as colour "fringes" along the lines dividing the dark and light areas of the image.

Our overall goal in this problem is to find the location of a point b that lies on the line between points A and C.

What do know from what's given?

Location of point A

Location of point C

The relative distance of point B along the segment/line AC (given as a ratio of 3:1)

Now that we have listed everything we know, lets figure out what we can calculate based on this information:

Since we have both the locations of points A and C, lets calculate the length of this segment. For this we can think of this edge as the hypotenuse of a right triangle that is formed from the height (which is the distance between the x-coordinates) and the base (which is the distance between the y-coordinates).

We'll need two equations here:

Distance:

Calculate the distances for the height and the base of this triangle formed from the segment AC (the hypotenuse of the right triangle)

a (base) = |x2 - x1| ... where A (x1,y1) and C (x2,y2)

b (height) = |y2 - y1| ... where A (x1,y1) and C (x2,y2)

Note: Absolute value is used here since distance is always positive

Pythagorean Theorem:

Once we know the distance of the base and the height, we'll be able to calculate the segment (aka the hypotenuse of this formed triangle)

c2 = a2 + b2

After we calculate the distances for a and b, we can then solve for c, giving us the length of segment AC. Great! We're halfway there - next is to figure out how far point B is from points A  and C, using the distance along the segment AC.

Recall the third piece of information we were given: the relative distance of point T along segment AC. How can we represent this information in an equation using the distance of segment AC?

The ratio to which point T splits the segment AC is given as 3:1 - this means that one part is 3 times as long as the other part. The natural question to ask here is "3 times as long as what?" This 'what' piece is what we want to find out - lets call it x.

Another important observation to make is that this ratio is describing two parts of a whole segment - so if we think of this is two pieces of a whole, we can think of it as '3 times something' and '1 times something' is equivalent to the entire segment.

So, using this terminology with x, lets rewrite what we said in words into an equation:

3x + 1x = c (Length of AC)

Solving for x, we see that x = [tex]\frac{C}{4}[/tex]

Now that we have the distance from point D to point T, and from Point T to point F, we can take up the final step of determining the location of T.

Lets imagine the entire segment ABC as the hypotenuse of a triangle again. This time we want to imagine (feel free to draw this yourself as well) a like straight down from T, perpendicular to the base of this right triangle.

What we have now is a small right triangle (with segment DT as the hypotenuse) within a larger right triangle (with segment DF as the hypotenuse). What this means is that we have two proportional triangles.

With this information, we can create a proportion statement that says:

(AT) Hypotenuse small Triangle / Height smallTriangle ~ (AC) Hypotenuse large Triangle / (b) Height large Triangle

Recall that we had solved for b in the beginning as the y distance between points D and F. This means the only variable missing is Height small Triangle, which results to be:

Height small Triangle = (AT) Hypotenuse small Triangle × (b) Height large Triangle / (DF) Hypotenuse large Triangle

Adding Height small Triangle to the y coordinate of point F gives us point T's y coordinate.

Now that we have the hypotenuse length and the height length of the small triangle formed by AT (as the hypotenuse) we can plug in those numbers into the Pythagorean  theorem to since for there final missing side: the base:

Base small Triangle 2 = (AT) Hypotenuse small Triangle 2 Height small Triangle 2

Finally, we add Base small Triangle to the x coordinate of point B gives us point T's x coordinate.

Ocean basins are created along blank convergent boundaries that break apart continental lithosphere.

Converging boundaries produce foreland basins through tectonic compression of oceanic and continental crust during lithospheric flexure. The collapse of the rift zone or the emergence of an ocean might result from tectonic extension at divergent borders when continental rifting is taking place.

The North Sea is an illustration of a basin created by lithospheric stretching; it is also a prominent site for considerable hydrocarbon deposits. Another comparable feature is the Basin and Range province, which forms a sequence of horst and graben formations and occupies the majority of the US state of Nevada.

The pollutant responsible for major declines in the populations of pelicans, ospreys, and other marine birds was DDT.

A pollutant or novel entity is a substance or energy that is introduced into the environment and causes undesirable effects or reduces the usefulness of a resource. These can be of both natural and anthropogenic origin. Contaminants can pollute the environment or become a public health problem when they reach levels high enough to cause significant adverse effects.

Pollutants can cause long-term or short-term harm by altering the growth rates of plant and animal species and by affecting human comfort, well-being, health, and property values. There is nature. Some contaminants are biodegradable and therefore do not remain in the environment for long periods of time. However, the decomposition products of some contaminants are themselves contaminated, such as the products DDE and DDD resulting from the decomposition of DDT.

Pollution has far-reaching negative effects on the environment. When analyzed in terms of planetary boundaries, human societies have unleashed new entities far beyond their safe levels.
