Ductility is the ability of the ability to undergoing significant plastic deformation before the rapture. An example of the cup and cone fracture can show this, which is a type of failure observed in ductile metals. Being subjected to uniaxial force it is essential to separate the body into pieces as the application of intense tensile stress. As ductility and malleability are all ways correlated thee material properties depend on the temperature of the metal. Rare earth metal is not commonly found in places and the chemical composition also varies as these are diverse and are used by people in everyday device some smartphones also consist of these elements.Q5: Which of these constitutes geologic evidence that Arizona has been wetter in the past than it is today?
a. Fossil dinosaur trackways.
b. Granitic rocks exposed deep in Grand Canyon.
c. Halite and gypsum deposits.
d. Mineralized rocks in fault zones that bound basins.
Answer:
D. Mineralized rocks in the fault zones that bound basins.
Explanation:
The geology of Arizona starts with the formation of the Precambrian period. When igneous and metamorphic rocks were overwritten by Yavapai and Mazatzal orogenies in the Proterozoic era. The Grenville orogeny in the east caused Arizona to fill with the sediments filling a shallow sea. The region oscillated between the terrestrial and shallow oceanic conditions during the paleozoic era multicellular life became common. The limestone forming a shallow sea, stare caves and important ore deposits, and marine deposits were common at this period. Arizona thus had extensive mineralization in veins, due to hydrothermal fluids.1. In a hot-spot volcanic island chain, such as the Hawaiian Islands, all islands possess active volcanoes simultaneously and therefore the risks of volcanic hazards are about the same for all islands.
a. true
b. false
Answer:
True.
Explanation:
As the volcanic islands of Hawaii are still considered to be in an active zone, as the Hawaiian islands are believed to be formed on the hotspot of eruptions ie. the active plate boundaries from below the surface these tend to move westwards direction from the main island of Hawaii. As we go from east to west the chain of rocks gets older and then forms a ring-shaped pattern hence called the ring of fire. Thus there is a great risk of volcanic hazard as these are fault lines being associated with high magnitude tectonic earthquakes. They can have a seriously damaging impact upon other islands as well and this considered to be highly hazardous. As various vents and mounds of volcanic nature lie within the oceans of the Pacific plate.Question 1 2 pts The answer to combat climate change is: Generate electricity from renewables All of the options given here Shift all our energy use to electricity Conservation and sustainability mindset

The answer to combat climate change is: Generate electricity from renewables All of the options given here Shift all our energy use to electricity Conservation and sustainability mindset
Answer:
Conservation and sustainability mindset
Explanation:
Conservation and sustainability mindset is the answer that will allow us to combat climate change. Climate change occurs due to a variety of factors, but these are all linked to the irresponsible use of resources by humans. Climate change is allowed to continue because people do not think in a way that prioritizes sustainability, nor do they think about future generations. However, if they did, we would be a lot more likely to stop the threat of climate change.
Which individual activities and
choices do you find most harmful to the environment and
why?
Answer:
Some of the individual activities are overexploitation or overutilization of resources.
Explanation:
Humans influence the natural environment to large extends some times beyond repairs as their consumption and production are both ways harmful to the environment, as the industries and manufacturing sector have alone contributed to large scale pollution over the land and water sphere. Large scale exploitation of resources and overuse have resulted in depletion and mass extinctions of species and as a result, have downgraded the performance of the earth's natural ecological systems to bounce back. Use of agricultural HYV seeds have destroyed soil productivity and damaged the flow of nutrient from the soil. Also, the use of artificial pesticides and greenhouse gases have punctured the entire ozone-producing gas and thereby have created climate havoc on the earth's surface.List the major factors that affect atmospheric CO2on long geological time scales. Draw a simple box model of the influences on atmospheric CO2, showing the major reservoirs and fluxes. The model does not need to be quantitative.
Carbon dioxide or CO2 is one of the main greenhouse gases that accelerates global warming.
A greenhouse is a place where a particularly cold or hot climate is maintained.
Scientifics use this analogy with gases like CO2 because what they generate is a coat that keeps the sun's rays inside the oxygen layer, so these rays enter and heat the earth, unable to escape.
Industrial factories and cars are the largest carbon emitters. It all started in the Industrial Revolution
3. What is the thickness and volume of the Earth's sedimentary rock shell in various tectonic processes?
Answer:
Earth's sedimentary rock can be explained from the crustal plates on earth.
Explanation:
Earth's most sedimentary rocks are formed in continental or land crust as the oceanic crust is made up of heavier materials such as basalt and has a density of 2.9g/cm cube. The tectonic forces that originate deep within the earth layers and the arrange of rocks found at greater depths which are responsible for the density and thickness of the continental land crust are volcanism and earthquake activity. Igneous and metamorphic rocks that form along with the sedimentary rocks in the earth's crust and areas of shallow beds close to the shores of continental shelves are of less density and less thickness and those submerged beneath this layer are those of higher mass and density. About 40 % of the earth's surface and 70 % of the continental volume is dominated by the earth's crust of terrestrial in origin. In due course of time, the mountain upliftment and isostasy formations have developed the crustal thickness.5.

Question 42 options:
CO2
N2
Ozone
CH4
Answer:
N₂
Explanation:
The primary greenhouse gases in the atmosphere are carbon dioxide, methane, nitrous oxide, water vapour and ozone. These gases allow sunlight to reach the Earth's surface unhindered. The sunlight heats the surface. The heat as infrared reradiated to the atmosphere, the greenhouse gases absorb the heat energy. They do not allow heat to escape back trapping' the gases in the lower atmosphere.
Nitrogen is an inert gas present in the atmosphere is about 78%.
Only some nitrogen-fixing bacteria such as Rhizobium which fixes atmospheric nitrogen into the soil.
Thus, N₂ (nitrogen) is not a greenhouse gas.
why can't high quality energy resources such as oil be recycled?
Answer:
Oil is one of the most efficient and widely used energy resources. These are fossil fuels. When the ancient plant and organisms dies they accumulates at the bottom of the seas, which are then covered by the sediments such as mud and sands, forming various rock layers. These trapped organisms an plants after millions of years turn into fossils, by undergoing the fossilization process. These are non-renewable energy resources or conventional sources of energy. In addition to oil, coal, petroleum and natural gas are also some examples of non-renewable energy.
Thus, the high quality resources or energy such as oil, petroleum and natural gas cannot be recycled.

I don't understand principles of constant proportions can someone explain this concept to me and how it referes to salt in seawater.
The principles of constant proportions in chemistry state that a compound will always have the same proportion of elements by mass. In the case of salt in seawater, this means that the ratio of sodium to chloride ions will be the same regardless of the location of the sample.
Explanation:Principles of Constant Proportions in ChemistryThe principles of constant proportions in chemistry state that a compound will always have the same proportion of elements by mass. This means that the ratio of the masses of the elements in a compound will always be the same, regardless of the amount of the compound.
When it comes to salt in seawater, the principles of constant proportions mean that no matter where you sample seawater from, the ratio of sodium to chloride ions will be the same. This is because the composition of salt (sodium chloride) in seawater remains constant.

The principle of constant proportions states that the elements in a pure chemical compound are always combined in the same proportion by mass. This principle applies to the salt in seawater, which is primarily Sodium Chloride, with a consistent proportion of Sodium and Chloride. It is also exemplified in the way certain salt-loving microorganisms thrive in constant salt conditions, and in the solubility equilibrium of salt in seawater.
Explanation:The principle of constant proportions, also known as the law of definite proportions, states that in a pure chemical compound, the elements are always combined in the same proportion by mass. This principle applies to seawater and its salt content. Salt in seawater is primarily Sodium Chloride (NaCl). Regardless of the location, the proportion of Sodium and Chloride in Sea Salt is always nearly constant, approximately 39.34% Sodium and 60.66% Chloride by mass.
For example, the principle is evident in the way certain microorganisms called halophiles ("salt-loving") thrive in marine environments where salt concentrations hover at 3.5%. Extreme halophilic organisms, like the red alga Dunaliella salina and the archaeal species Halobacterium, can even survive in hypersaline lakes such as the Great Salt Lake or the Dead Sea, which are several times saltier than the ocean.
Another facet of this principle can be seen in how solubility products work. The solubility of a substance, such as salt in seawater, can vary from essentially zero to infinity, producing saturated solutions when the solubility limit is exceeded. The equilibrium between the dissolved and undissolved salt is also part of this principle of constant proportions.

Question 3(Multiple Choice Worth 3 points) What is most likely true about a rock that contains small mineral crystals? . The rock is igneous. II. The rock cooled quickly. III. The rock cooled on earth's surface. I only Il only Ill only I and Il only I, II, and lI
Answer:
Option (4)
Explanation:
The igneous rocks are formed due to the crystallization of magma at or below the earth's surface. These rocks are comprised of minerals (crystals) that usually ranges from fine-grained to coarse-grained in terms of size. The size of these crystals are directly related to the cooling rate of magma. If the rate of cooling is fast, then it produces fine-grained crystals. Whereas, if the rate of cooling is slow, then it produces coarse-grained crystals.
The magma when comes out to the earth's surface, it cools immediately. As a result of which coarse grained crystals are formed.
Thus, the fine grained crystals are generally formed in the intrusive igneous rocks such as granite where the finer crystals are formed due to the faster cooling rate of magma.
Hence, the correct answer is option (4).
Which of the following formulas would you use to convert a temperature initially taken in degrees Fahrenheit to degrees Celsius?
Question 57 options:
C = F – 273
C = 9/5F + 32°
C = 5/9(F - 32°)
C = 5/9F - 32°
Answer:
C = 5/9(F - 32°)
Explanation:
If we compare the farenheit degree scales with the celsius degree scale, we find that the intervals between the same reference points are 180 ° farenheit and 100 ° celsius. 180 degrees farenheit are needed to cover the same temperature range of 100 degrees Celsius. From this information the unit factors of temperature change can be established.
Factor: 1 °C/1.8°F= 5/9
Also, to convert from ° F to ° C, we must subtract 32 degrees farenheit to reach the zero point of the celsius scale.
Then, the correct formula is:
C = 5/9(F - 32°)
On the winter solstice of the northern hemisphere, the subsolar point is located at____.
Question 28 options:
the Equator.
the Tropic of Cancer.
the Tropic of Capricorn
the Arctic circle.
Answer:
Option (3)
Explanation:
During the winter solstice in the northern hemisphere, the orientation of the earth axis is that it is tilted in the direction opposite to the sun. This means that during this time, the north pole is at the farthest distance from the sun which represents the darkest day of the year. It can occur on any of this dates, such as 20th, 21st, 22nd or 23rd of December every year.
The subpolar point is defined as the location on earth where the sun is directly overhead. This means that the light emitted from the sun strikes on earth exactly at 90°.
Thus, during this winter solstice, the sun is directly overhead in the tropic of capricorn.
Hence, the correct answer is option (3).

As he stated that the continent of South America and Africa were once part of the same Gondwana landmass, Similarly the North America eastern side and Western side of Europe were the same as the ones that were part of the Lurata i.e Northern super landmass. This can be found in the evidence given in the paleomagnetism theory. Wegener believed that the continental crust is formed from the slabs and these slab or plates are lighter in weight and float on thick liquid asthenosphere oceanic crust with the help of winds and ocean currents. Thus he concluded that rocks were once part of the supercontinent that broke with the moveGeologic evidence for Pangaea includes matching rock layers, fossils, and glacial evidence. The hypothesis of the eastern coast of North America joining with the western coast of Europe is supported by fit, fossils, and rock structures. Wegener's climatology background helped him notice similarities in climate and geological features across separated continents.
Explanation:Geologic evidence supporting the existence of Pangaea includes matching rock layers across continents, fossil evidence of similar plants and animals found in different continents, and glacial evidence including striations and till deposits.
The hypothesis that the eastern coast of North America once joined with the western coast of Europe is supported by fit of the continents like puzzle pieces, fossil evidence of similar plants and animals, and matching rock structures.
Alfred Wegener's background as a climatologist contributed to his hypothesis by observing that areas with similar climates, such as coal deposits in Antarctica, existed on continents that are now widely separated. This led him to consider the idea of continental drift, suggesting that these areas were once connected.

The concept that the natural world should be treated with the same respect as man-made achievements such as pyramids and cathedrals is associated with a ________.
a. conservation ethic
b. biocentric ethic
c. relativist ethic
d. preservation ethic
e. universalist ethic
Answer: a. conservation ethic
Explanation:
The conservation ethics emphasis over the protection and preservation of the natural world that includes forests, fisheries, natural habitats and biodiversity. It emphasis over the use, allocation, protection and exploitation of resources in such a manner that it does not affect the natural world. It emphasis over the fact that the resources should be preserved in the same manner as that of the man-made things such as pyramids and cathedrals.
The concept that the natural world should be treated with the same respect as significant man-made structures aligns with a preservation ethic, which values nature intrinsically, comparable to a biocentric ethic that considers all life as inherently valuable.
Explanation:The concept that the natural world should be treated with the same respect as man-made achievements such as pyramids and cathedrals is most closely associated with a preservation ethic. A preservation ethic underlines the idea that natural environments have an intrinsic value similar to culturally significant human creations and should be preserved in their natural state. This idea contrasts with a conservation ethic, which may prioritize human use and value natural elements based on their utility.
Considering the various philosophical standpoints related to environmental ethics, biocentric ethic is another concept worth noting. It advocates that all life has intrinsic value and deserves moral consideration. This approach is life-centered and supports actions that avoid ecological damage, similar to the intention behind a preservation ethic yet distinct in its reasoning and implications.
The stored form of glucose in the body is called
Answer:
Glycogen
Explanation:
Animals, including humans store this glucose fat in their cells, which are quickly available for energy. The excessive is stored in the liver, if you consume some extra carbohydrates the body stores the excess in the form of glucose. Mostly consisting of protein that comes from food about 300g per day. Human glucose is metabolized by glycolysis. The use of glucose in the cell in energy form is either by aerobic respiration, food sources of glucose can range from fruits, vegetables, and pulses. In plants, glucose is a product of photosynthesis also known as starch.The stored form of glucose in the body is called glycogen.
In animals including humans, glucose is primarily stored as glycogen. It is a polysaccharide made up of numerous glucose molecules connected by branches. In order to meet the body's energy needs during fasting or physical activity, the liver and muscles store glycogen. Glycogen undergoes glycogenolysis when blood glucose levels fall dissolving into individual glucose molecules to provide energy.
In contrast a process known as glycogenesis transforms extra glucose into glycogen during times of high blood sugar such as right after eating. This dynamic control of glycogen synthesis and breakdown keeps blood sugar levels stable and gives the body a ready source of energy.
