Answer:
The history of sun exists from the day earth came into existence. But the actual truth of the movements and other knowledge were known with time and studies. The Sun and all the planets together is called the solar system. This formation occurred from the formation of a giant cloud of dust and gases known as the solar nebula. This was 5 billion years ago . Bit the nebula had to collapse due to increased forces applied.
How could you tell if a line of islands was formed by a hot spot and tectonic plate movement?
Answer:
If the island chain is far away from plate boundaries and it is in a direction of the movement of the plate on which it is located, then those are good indicators that they are formed by hot spot volcanism and tectonic plate movement.
Explanation:
There are multiple types of island chains around the world according to the manner in which they have formed. One type is the island chains that have been formed by hot spot volcanism, and their direction has been determined by the movement of the tectonic plate on which they lie. An example of such islands is the Hawaii islands, located in the central part of the Pacific Ocean and the Pacific plate.
The two best indicators that it is this type of islands in question are their location in relation to the plate boundaries and their direction in relation to the tectonic plate movement. If the island chain is located far away from plate boundaries then it means that it is of hot spot origin. If the direction in which the islands are positioned corresponds with the direction of the plate on which they lie means that the plate's movement is determining their direction.

Explain the differences between political and physical maps (3-4 sentences)
Answer:
Physical maps typically give the viewer a general idea of how the landscape is. For example, it gives a general location of where mountains, deserts, rainforests, oceans, and other landforms are located at based on longitude latitude. Political Maps, on the other hand, gives a generalized to more specific idea of how each state/region votes for. In the United States, it is typically shown as red/blue, as in Republican-leaning/Democratic-leaning. There is no natural land form shown.

Explain why our Earth is fragile?
Answer:
The Earth is different because it has life on it…obviously. And the factors that make it so, is why it is regarded as a fragile planet.
Explanation:
For example, one of the reasons Earth supports life is its location in the solar system. The venerable Habitable Zone. If the earth was, say in Venus’ orbit for example, runaway greenhouse effect would create so much heat, it would not be able to hold surface water.
So we’re lucky to be in the correct distance from the Sun, however, distance is not the only factor here. If the planet was covered in ice for example, its reflectivity (also called albedo) would cause the surface temperature to be either cool, if albedo is high and vice versa.
So, again, we’re lucky to have just the right amount of surface reflectivity. How about our atmosphere? The atmosphere provides us with life sustaining weather, temperature regulation and shields us from deadly radiation. The composition of our atmosphere is crucial in how atmosphere interacts with solar radiation. Some gases, such as Carbon Dioxide and Water vapor, allow visible light to pass through which is good for those important things like…seeing. Unfortunately, these same gases prevent radiation from being reflected back out into space in what is referred to as The Greenhouse Effect. Every planet with an atmosphere has this at different degrees and is what heats up the planets. The dissipation of the greenhouse gases also determines for how long the planet will retain its heat, for example, water vapor may take a week while Carbon dioxide takes about 100 years. Again, luckily for us, we only have a trace amount of Carbon dioxide, less than 0.1% of it.
How about the one ingredient that we can’t do without? Oxygen? It turns out that we don’t have that much in the atmosphere. Only about 21% of our atmosphere contains oxygen. If we had less, we would have weak hearts, prone to diseases, slow and probably still be in the dark ages. If there was too much of it and someone farted, the atmosphere would simply combust and murder everyone since oxygen is highly reactive. The highest oxygen content that could be safely stored in our atmosphere is about 35%. Luckily we have giant recycling plants called…well, plants. We also have oxygen reserves in our oceans, crust and beneath ice caps.
The odds for all these factors that have occurred on our little blue marble, albeit over millions of years, to be replicated on another planet and support life as we know on earth is literally a 1 in a not-happening.
All these things are maintained by a very delicate natural balance and can unfortunately be undone by both natural and man-made effects. Hence, our planet is very fragile.

Explanation:
Calcium carbonate can break down to form calcium oxide and carbon dioxide. CaCO3 → CaO + CO2 The oxygen atoms on the product side are not balanced because there are only two oxygen atoms in CO2 not balanced because there is only one oxygen atom in CaO. balanced because the total number of oxygen atoms is 3. balanced when a coefficient of 3 is placed in front of CO2.
Calcium carbonate can break down to form calcium oxide and carbon dioxide. The balanced chemical equation has been 3 CaCO₃ ⇒ 3 CaO + 3CO₂
What is balanced chemical equation ?The term balanced chemical equation is defined as the total number of mass of reactant is exactly equal to the total number of mass of product.
The balanced equation can be given to follow the law of conservation of mass. With equal number of atoms of all elements are present on the product and the reactant side in the reaction.
The given equation is written with addition of 3 as a coefficient to the carbon dioxide in above reaction is as follows:
CaCO₃ ⇒ CaO + 3CO₂
The number of elements of oxygen in reaction on product side has been 6 atoms for carbon dioxide and 1 oxygen atom for calcium oxide. The total oxygen on product side has been 7. The reactant has the presence of 3 oxygen atoms. So, for balancing the equation.
The reaction has been balanced with equal atoms on both the sides as follows:
3 CaCO₃ ⇒ 3 CaO + 3CO₂

In ancient Egypt, what role could a woman play in medicine? 1 Women had many rights but were unable to practice law or medicine.2 Female physicians could only be trained by women and could only treat women. 3 Any woman who could read or write would be able to be trained as a physician. 4 Women were not respected and could not be trained as physicians.
Answer:
Correct answer is 3 Any woman who could read or write would be able to be trained as a physician.
Explanation:
Third option is correct because there were many female doctors in Egypt, which is shown by historical evidence. We even have the name Merit-Ptah, which is the first known female doctor in Egypt. She lived around 2900 BC.
First option is wrong, because women had right to be educated.
Second option is wrong because there is no evidence that only women could train women.
Last option is wrong as women were highly respected in the society. We even have examples of pharaoh who were women.

Give reasons to believe climate change is real.
The planet's average surface temperature has risen about 2.05 degrees Fahrenheit (1.14 degrees Celsius) since the late 19th century, a change driven largely by increased carbon dioxide and other human-made emissions into the atmosphere. Most of the warming occurred in the past 40 years, with the six warmest years on record taking place since 2014. Not only was 2016 the warmest year on record, but eight months out of that year — from January through September, with the exception of June — were the warmest on record for those respective months.

What agricultural operations are affected by the standards set forth by the OFPA? Select all that apply.
livestock production
crop production
oversight of federal grazing lands
organic handling
Answer:
Explanation:
The only option that is not affected by the standards set forth by the OFPA is the third option. The oversight of the federal grazing lands is done by the Bureau of Land Management (BLM), which is an agency under the United States Department of the Interior.
The Organic Food Production Act (OFPA) empowers the National Organic Program which is been provided by the United States Department of Agriculture (USDA). This program acts to regulate organic products which must meet a certain requirement/standard before they can be termed "organic". These standards starts are used to access the producer and the handlers before they are certified. These standards include livestock production, crop production and organic handling.

Describe how population distribution affects the cultural landscape.
Answer:
The population distribution promotes a more urban or more rural natural landscape.
Explanation:
Communities with a high number of inhabitants tend to have a larger population distribution. This makes these cities consume more natural resources, reducing the rural landscape and establishing a more industrial, dynamic, urban and fast culture. These communities tend to grow and industrialize more and more, becoming more and more urban.
On the other hand, smaller communities tend to establish themselves in a more rural culture and at a calmer and more harmonious pace than urban communities. These communities are not distributed so much that they suppress their natural resources, moreover, these communities tend to decrease with the migration of their members, with the passage of time.
