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.

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.
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.

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.

Answer:

Explanation:
Neptunist's believed that the crust precipitated from water that once covered the earth .
Answer:
The crust precipitated from water that once covered the earth.
Explanation:
Neptunists versus Plutonists. The origin of rocks became a topic of controversy between two schools of geologists near the end of the 1700s. The Neptunists held that all crustal rock was precipitated from an ocean that covered the entire earth before the beginning of life. The Plutonists, on the other hand, believed that what we today call igneous rock has a different origin. The Plutonists believed that these rocks arrived at the surface of the earth as molten rock, called lava. Geological field observations solved the controversy in favor of the Plutonists. Basalt, hardened lava, was traced to the volcanic vent from which it had erupted.
Based on this map of oil imports, which nation imported the greatest number of oil barrels each day in the years before 2006? A. China B. Australia C. Canada D. the United States
Answer:
D. the United States
Explanation:
Until the year of 2006, the largest importer of oil in the world was the United States. In fact, the United States were the leader in oil imports for almost a century. In the mid 2000's though, this started to change, with the United States starting to import less and less oil, while increasing their own production, as well as using alternative energy sources. China, on the other hand, was constantly consuming more and more, and since it lacks it as natural resources, it was imported, so China propelled to the top as the biggest importer of oil in the world.

Where did the battle of midway take place
The Battle of Midway took place near the Midway Atoll in the North Pacific Ocean and was a decisive turning point in World War II, resulting in a significant victory for the United States Navy over the Imperial Japanese Navy.
The Battle of Midway took place near the Midway Atoll, which is located in the North Pacific Ocean, approximately halfway between Asia and North America. This pivotal battle occurred from June 4 to June 7, 1942, during World War II.
The Midway Atoll was of strategic importance to both the United States and Japan due to its location. The Japanese aimed to eliminate the United States as a strategic power in the Pacific by capturing Midway and establishing a base there. However, the United States intercepted Japanese plans through code-breaking efforts and prepared a defense.
The battle resulted in a decisive victory for the United States Navy, turning the tide of the Pacific War in their favor. The loss of four Japanese aircraft carriers and significant naval personnel weakened Japan's naval power and marked a significant turning point in World War II.
How are igneous rocks formed? View Available Hint(s) How are igneous rocks formed? Igneous rocks are produced by the weathering and transport of pre-existing rocks. Igneous rocks are formed by the cooling and crystallization of molten rock. Igneous rocks are formed only from material ejected during a volcanic eruption. Igneous rocks are formed by the cooling of magma above Earth’s surface and lava below the surface. Igneous rocks are formed by recrystallization due to intense heat and pressure.
Answer:
Igneous rocks are formed by the cooling and crystallization of molten rock.
Explanation:
Igneous rocks are rocks that forms by the cooling and solidification of magma. Magma is a molten rock. When the molten rock reaches the earth surface, it is called a lava.
Some igneous rocks form deep within the crust and we say they are intrusive or plutonic igneous rocks.
Some forms on the surface of the earth crust. We call them volcanic or extrusive igneous rocks.
Some igneous rocks forms very close to the surface and we say they are hypabyssal igneous rocks.
