The atlatl was an ancient tool used to throw spears with greater force than throwing them by hand. The first Americans brought atlatls with them when they came to North and South America. Why was the atlatl especially helpful for the first Americans?
The atlatl would have been the ideal weapon for hunting small, fast animals.
The atlatl would have made them more successful in fighting the people who were already living in the Americas.
The atlatl would have helped hunters throw a spear with enough force to take down large animals.
The atlatl would have allowed the first Americans to hunt and gather healthier foods.
Answers
From the physics side: this tool allowed the spear to be thrown with greater overall speed and acceleration = more accuracy and force.

For approximately how many thousands of years has the Earth been in the peak of an inter-glacial period within the present ice age?
Answers
Answer: The glacial-interglacial cycle is triggered by changes in Earth's orbit around the Sun, and, as a result, there is approximately 100,000 years between interglacials (or glacials).
Explanation:
Within the present Ice age, the earth has been at the peak of an interglacial period for approximately 100,000 years.
What is the Ice age?The ice age which is also called the glacial age is any geologic period during which thick ice sheets cover vast areas of land. Periods like this have large-scale glaciation which may last several million years and dramatically reshape the surface features of entire continents.
A major number of ice ages have occurred throughout earth's history. During Precambrian time dating back more than 570 million years, the earlier ice age took place. And the most recent took place during the Pleistocene Epoch which us 2.6 million to 11,700 years ago.
The lesser recent glacial stage called the Little Ice Age began in the 16th century. It advanced and receded intermittently over 3 centuries in Europe and many other regions.
The ice age lasted until 11,500 years ago.

Type 19 53 48.36 N 155 34 58.11 W in the search bar on Google Earth, and zoom out to an eye altitude of ~615 miles. The magma that resulted in the formation of these islands was generated by what process?a. decreased pressure (arrow "b") b. the addition of water (arrow "d", which shifts the solidus to the left) c. increased temperature (arrow "a")
Answers
Answer:
Option C = increased temperature (arrow "a").
Explanation:
Magma is used by people studying geography or scientists at large to describe the molten substance(which is very hot) which can be found under the ground.
From the question above we see that there is something(a map) to see on the search engine that is "19 53 48.36 N 155 34 58.11 W".
The result for the search brought a map and there is need to zoom it out to zoom out to an eye altitude of approximately 615 miles.
The magma seen here is as a result of changes in Temperature which is actually increase in temperature which in turn forms the island. This one of the ways in which islands are formed.
Magma is utilized by people studying geography or scientists at large to describe the molten substance which can be found under the earth's surface.
How does Magma create Islands?
The island is formed when magma builds up and breaks the ocean's surface. In some cases, like the island of Hawaii, landmasses are gathering together. Each volcano is a little different, as are the levels at which it builds.

A).The burning of a natural gas releases carbon dioxide
B).Natural gas can be difficult to ship long distances.
C).Natural gas smells like rotten eggs
D).Natural gas is quiet flammable
E).Natrual gas removal can result in sinkholes
Answers
Answer:
The burning of natural gas releases carbon dioxide is not a correct statement.
Explanation:
Natural gas is a natural resource that is part of the fossil fuels. While the majority of fossil fuels have a very bad reputation when it comes to pollution because they release enormous amounts of carbon dioxide, this is not the case with natural gas. Natural gas actually is by far the best when it comes to pollution as it releases Incomparably smaller amounts of pollutants in the atmosphere.
Basically, natural gas is a relatively clean fossil fuel, and this is one of the reasons why it is used more and more around the world. Not just that this natural resource is much cleaner, it is also relatively cheap, making it ideal for usage. It has to be mentioned that it does release pollutants like nitrogen oxides, sulfur, mercury, and particulates, though they are all at negligible levels.

Why is the motion of the water in the bin considered a cycle? What could stop the cycle? What could accelerate it? can someone help plz <3
Answers
As water on earth moves in a cyclic form, it is recycled and remade through various processes.
In order to know the motion of the water in the bin, we must know the process of evaporation, condensation, and precipitation
The water that continues to fall back in the form of snow, rain, or hail is again taken up in a cyclic process the next day. The cycle works through the solar heating mechanism. Rising in temperature, increase in salinity can lead to acceleration, and condensation or cooling down can stop the cycle.Hence as water cycles form the oceans to atmosphere it moves in an endless cycle.

Explanation:
because a barometer does something else
A weather map, commonly referred to as a synoptic weather chart, shows different meteorological features across a certain area at a particular time and contains different symbols with different meanings.
What is Weather Map ?From the middle of the 19th century, these maps have been utilised for research and weather forecasting.
Isothermal maps display temperature gradients that can be used to identify weather fronts. The location of the jet stream is shown using isotach maps, which analyse lines of equal wind speed over a surface of constant pressure of 300 or 250 hPa.
Tropical cyclone motion can be determined by using constant pressure charts at the 700 and 500 hPa levels.
The surface weather analysis, which depicts isobars to show areas of high atmospheric pressure, is a popular type of surface weather map low and high pressure.
These maps display the cloud codes, which are converted into symbols and shown alongside other meteorological information from synoptic reports given by skilled observers.

Answers
Answer: Raymond Wang: How germs travel on planes – and how we can stop them
1. After completing the unit and watching the video, explain how the unit about oceans and the video about germs on a plane relate?
In his video Raymond explains how the diseases are transmitted through planes from one country to another and the difficulties faced to prevent the spread of diseases due to the air circulation in the planes. It is always difficult to screen the person with disease and prevent them from getting into the plane since the air circulates in the conventional cabins. When a person sneezes, the air will get swirled multiple times and spread the disease.
2. Using examples from the video, explain why it is difficult to keep people who are sick off of planes.
It’s difficult to pre-screen for diseases. When someone goes on a plane, they could be sick and actually be in this latency period in which they could have the disease but not exhibit any symptoms and could possibly spread the disease to many other people.
3. How does Wang illustrate what happens in a conventional airplane cabin when someone sneezes?
He illustrates how the air is just being circulated throughout the plane. When someone sneezes, the air is just being circulated into the air. This means that everyone on that plane has breathed in that person’s sneeze because it’s such a compact place.
Answer:
1. The air circulates in the cabins so when a person sneezes the air will get swirled around multiple times and spread the disease.
2. Many diseases like sars, don't show up on simple testings and the person could have a disease early on and it would be nearly impossible to identify.
3. He illustrates how the air is being circulated throughout the plane. When someone sneezes, the contaminated air is being circulated throughout the plane. This means that everyone on that plane has breathed in that person’s sneeze because it’s so compact.
4. Wang’s invention can stop the spread of disease because it pushes all of the air down meaning if someone coughed or sneezed, instead of spreading around the cabin, the air would get pushed down to the filtration system before reaching multiple people. The word “flow” has to do with his solution because he is redirecting the flow of the air in the airplane downwards to prevent more people from getting sick.
