According to our present theory of solar system formation, which of the following best explains why the solar nebula ended up with a disk shape as it collapsed?
(A) Nuclear fusion occurring in the core of the protosun produced energy that heated the nebula. (B) As the cloud shrank, its gravitational potential energy was converted to kinetic energy and then into thermal energy. (C) Radiation from other nearby stars that had formed earlier heated the nebula. (D) The shock wave from a nearby supernova heated the gas. (E) Collisions among planetesimals generated friction and heat.
Answer:
(B) As the cloud shrank, its gravitational potential energy was converted to kinetic energy and then into thermal energy.
Explanation:
From the theory of the formation of the solar system, the solar nebula which is a massive interstellar cloud flattened into a disk shape as it collapsed due to the gravitational potential energy which was converted to kinetic energy and ultimately thermal energy. This then allowed nuclear fusion to occur and a protosun was formed at the core of the nebula.
Initially, the particles that constitutes the solar nebula were moving randomly in an uncordinated fashion. As the gravitational pull reoriented the particles into a more coordinated pattern. The pull contracted the vast nebula into a smaller size and this was furnished with a kinetic energy. This energy resulted into the heating of the nebula and the centre became very hot. The gravitational pull caused an inward pull on the particles while the pressure of the condensed nebula resulted in an outward pull.
The disk shape of the solar nebula as it collapsed was due to the conservation of angular momentum, with faster rotation flattening the nebula into a disk, and slower material at the poles falling into the center, forming a star and a disk of planetesimals.
Explanation:According to our present theory of solar system formation, the solar nebula ended up with a disk shape as it collapsed due to the conservation of angular momentum. As the nebula contracted, its rotation caused it to flatten into a disk. This occurred because material falling towards the center converted its gravitational potential energy into kinetic energy, which then transformed into thermal energy. This process caused the nebula to rotate faster, much like a figure skater who pulls in her arms to spin faster. Near the poles of the nebula, where orbits were naturally slower, the material fell directly into the center, while faster-moving material at greater distances from the poles formed a flat, rotating disk around the central object, which became a star. Over time, this rotating disk resulted in the formation of planetesimals and eventually planets, with the central hot region of the nebula vaporizing most of the solid materials originally present and ultimately becoming the sun.

According to our theory of solar system formation, what three major changes occurred in the solar nebula as it shrank in size?
A.Its mass, temperature, and density all increased
B.Its gas clumped up to form the terrestrial planets, nuclear fusion produced heavy elements to make the jovian planets, and central temperatures rose to more than a trillion Kelvin.
C.It gained energy, it gained angular momentum, and it flattened into a disk
D.It got hotter, its rate of rotation increased, and it flattened into a disk
Answer:
D.It got hotter, its rate of rotation increased, and it flattened into a disk
Explanation:
The nebula theory proposes that our solar system was born about 4.6billion years ago out of a gigantic interstellar cloud.
These interstellar gases are made up of some gases and some microscopic particles. The gravitational pull by the particles caused the cloud to collapse inward. The collapse triggered increase in temperature and the rate of rotation spiked. This caused the collapsed cloud to flatten into a disk with a centre bulge which later forms the sun.
As the solar nebula shrank, it got hotter, its rate of rotation increased, and it flattened into a disc shape from which the planets eventually formed.
According to the theory of solar system formation, as the solar nebula shrank in size, three major changes occurred. Firstly, as the size of the nebula decreased, the nebula got hotter due to the conservation of energy principle. Next, its rate of rotation increased. This is due to the conservation of angular momentum. Lastly, it flattened into a disk under the influence of gravity creating a spinning protoplanetary disk from which planets eventually formed.

Many climate scientists set the upper limit of carbon dioxide that we should not cross at 560 ppm. In 2011, the atmospheric concentration was 390 ppm. Unless dramatic changes are put into place, we will probably surpass the 560 ppm threshold before the end of this century. What predicted effects could this bring?Question 5 options:1) melting of the Greenland Ice Sheet2) glacier and permafrost melt3) ocean acidification4) rapidly accelerated warming5) All of the above are correct.
Answer:
5) All of the above are correct.
Explanation:
Carbon dioxide is a greenhouse gas. When its concentration in the atmoshpere rises above normal, it can affect the climate pattern and lead to climate change.
Carbon dioxide prevents outgoing solar radiation from escaping the earth's atmosphere and this warms the earth surface. The more the presence of the gas, the more heating that would result.
Excessive release of carbon dioxide causes a phenomenon known as global warming. Global warming is simply the warming of the globe.
The consequences includes:
Melting of Greenland ice sheets as temperature spikes. Glaciers and permafrosts in temperate and polar regions will melt. Ocean acidification due to dissolution of excess carbon dioxide in sea water to form carbonic acid. There is general increase in surface temperature due to accelerated warming.Final answer:
Crossing the 560 ppm threshold of atmospheric CO2 concentrations will likely result in multiple significant environmental impacts, including the melting of the Greenland Ice Sheet, glacier and permafr-ost melt, ocean acidification, and rapidly accelerated warming. All of these above (5) is correct, contributing to global climate change and its associated risks.
Explanation:
Many climate scientists have set the upper limit of carbon dioxide (CO2) concentration that we should not cross at 560 parts per million (ppm), beyond which significant adverse effects on the global climate are expected. As of 2011, the atmospheric concentration of CO2 was 390 ppm, and we are on a trajectory to surpass the 560 ppm threshold before the end of this century without dramatic intervention. The predicted effects of crossing this threshold include a wide range of environmental disruptions.
Melting of the Greenland Ice SheetGlacier and permafr-ost meltOcean acidificationRapidly accelerated warmingThese outcomes are interconnected and can lead to compounded impacts on global climate systems, sea levels, biodiversity, and human societies. The evidence overwhelmingly supports that all of the above mentioned consequences are correct and are likely to occur if the 560 ppm threshold is exceeded, underscoring the urgent need for mitigation efforts to address the rise in atmospheric CO2 concentrations.

The moderate temperatures of islands throughout the world has much to do with water's high evaporation rate. absorption of solar energy. poor conductivity. vast supply of thermal energy. high specific heat capacity.
Answer:
high specific heat capacity
Explanation:
The water is one of the most influential factors when it comes to the climate on the planet Earth. The most affected regions by the water are the islands, peninsulas, and coastal regions. These regions tend to have much more moderate climates, with the variations of the maximum and minimum temperature being relatively low. The reason for this is that the water has a high specific heat capacity, or rather the highest heat capacity of any liquid. This results in the water to be able to cool down much slower than the land, but also warm up slower than the land, thus it is having a much more constant temperature with smaller variations over longer periods of time.

During an earthquake, buildings and roads collapse. This causes people to move to new locations and find new homes. Which effect of short-term environmental change is presented in this scenario? Speciation adaptation forced migration behavior change
Answer:On ed its answer choice C
forced migration
Explanation:
The scenario illustrates the effect of forced migration caused by an earthquake, leading to short-term environmental change where people must relocate. This change can also result in habitat isolation and significant genetic shifts within the affected population.
Explanation:During an earthquake, buildings and roads collapse, leading people to move to new locations and find new homes. This scenario presents the effect of forced migration as a result of short-term environmental change. Forced migration occurs when populations or individuals must leave their current habitat due to sudden and significant changes in their environment, such as those resulting from natural disasters.
Natural events like earthquakes can cause the phenomena known as the bottleneck effect, where a large portion of a population is wiped out randomly. The survivors' genetic structure then becomes representative of the whole population's genetic makeup, which can lead to changes in biodiversity and eventual habitat isolation. This habitat isolation can hinder reproduction with parent species, leading to the independent evolution of the new population.

The layers of the Sun, ranked from farthest to closest to its core, are the corona, chromosphere, photosphere, convection zone, radiation zone, and core.
The various layers of the Sun are ranked by their distance from the Sun's core, from the greatest distance to the least, as follows: corona, chromosphere, photosphere, convection zone, radiation zone, and finally the core. The corona is the outermost layer of the Sun's atmosphere with temperatures in the range of a few million Kelvin. Beneath the corona lies the chromosphere, which is a layer of the Sun's atmosphere that appears bright scarlet during a solar eclipse and has a temperature of around 104 K. The photosphere is considered the Sun's visible surface, with temperatures ranging from 4500 K to 6800 K. The energy generated at the core of the Sun is transported outward through the radiation zone where energy transfer occurs primarily through radiation due to the high density of the matter. The convection zone is the region where hot plasma bubbles up to the surface, losing heat and then sinking back down to transport energy through convection. At the center lies the core, where nuclear reactions take place that generate the Sun's energy.

What was unique about the Indus Valley settlements? Which event likely caused the Indus Valley Civilization to decline?
1. The Indus Valley settlements were not like the settlements of the other early civilizations. They were built on higher ground instead of the lower parts so that they can be protected from floods. The houses were built in the same manner and had the same sizes. The streets were made in strait lines and intersected in right angles. All of the houses had bathing areas and were connected to a sophisticated drainage system. Also, the settlements were not made for defense, as the civilization was a peaceful one.
2. It is still not clear as to why the Indus Valley civilization collapsed, but there are two theories that have a big support. One of them is that the Aryan people invaded the region, which corresponds with their migration tot he Indian subcontinent, and that their invasion destroyed this civilization. The problem with this theory is that there's not a single clue of war and destruction. The other theory is that the climate changes in this period changes the flows of the rivers, which resulted in failing crops year after year, and the civilization was not able to sustain itself anymore, thus dismantling into smaller divisions.
Answer:
The Indus Valley settlements were special because it was extremely advanced, even more advanced than Mesopotamia. They
built their cities on high rises so they weren't flooded durning monsoon season. They also had their cities laid out in a grid
pattern. Scientists/researchers think that the Indus Valley Civilization had it's downfall because of a severe prolonged drought.
