Valerie Beketova Dr. Bennett AP Environmental Science 10 December 2015 Chapter 14 Outline Earth is a very dynamic planet Earth is made up of different layers: - Core - interior made up of dense, extremely hot metal, mostly iron. It is the most inside layer of earth. - Mantle - hot, pliable layer that surrounds the most inner layer, the core. It is less dense than core.
Its outer boundary is around 2,890km beneath the earth’s surface. 3. The Mantle: The mantle is the layer between the crust and the outer core, which is the broadest section of the Earth. It has a wideness of roughly 2,900.
1. Gravity- Newton’s law of gravity states that everything that goes up must come down. Gravity causes the mass of our body or objects to be pulled towards the earth. 2. Inertia- Inertia is a force that stays in the state of rest or unchanged unless a greater external force acts on it.
When the layers of the Earth move it causes the tectonic plates (aka: plate tectonics) to move which causes the Alaskan Way Viaduct to collapse. The layers of the Earth are the inner core, outer core, mesosphere, asthenosphere, upper rigid mantle, oceanic crust, and the continental crust. The Density Column lab showed how things can have different densities like the layers of the Earth. It also showed how things that are most dense stay more towards the bottom and least dense stuff stays more towards the top.
Gravity is caused by the penetration of the centers of the sun and planets without any diminution, according to Sir Isaac Newton. Francis Bacon, English philosopher of science, believes that science make little progress because there isn’t a specific goal sciences just keep providing new discoveries.
Astronauts often report that feeling weightless is the single most intense experience about space travel (Liapi and Ackermann 158). This is because you have always been exposed to the 9.81 m/s^2 of gravitational pull on Earth for your entire life. We take that for granted and do not even realize that we are always being pulled to Earth’s surface at that acceleration because we have always been exposed to it and know of nothing different. Humans have been exploring space for over fifty years, many successful contributions to human’s achievements in space have been completed in this time. This includes landing on the Moon, as well as creating the International Space Station (ISS) for humans from differing countries to come together to explore space together (Cain 336).
The inner core is too hot to hold a permanent magnetic field and is slowly becoming thicker as more of the outer core solidifies slowly over time due to the gradual cooling of the Earth. Chemical Divisions of the Earth's Layers The Earth's layers are also classified chemically as the Crust, Mantle, Outer Core, and Inner Core.
We wished to know about all the things which make the earth
Inertia is a tendency of an object to resist change in its state of motion. More massive objects have more inertia; that is, they have more tendency to resist changes in the way they are
Centrifugal forces are forces are forces that tend to drive a nation apart, rather than unite a nation. During the past half century in the United States, many centrifugal forces have affected this country continuously. One especially challenging force is the huge amount of diversity in the United States. Different religions, languages, culture, customs, immigrants, and ethnic groups clash against each other. This raises the issue of racism, which makes many minorities feel discriminated against.
Essentially for something of this gravity to occur something has to go really poorly. This thing is reason. Reason becomes corrupted. Both Dr. Crockett and St. Thomas Aquinas provide some guidance on how this occurs. They both point to the corruption of reason.
For example there is centrifugal force which is what is used for the duration of the time that you spend cradling the ball. Centrifugal force is the outward force on a mass when it is rotated which causes it to be more difficult for something to move and change location. An example of this is when you are spinning a bucket of water around on your arm and none of it falls out because you are going so fast. This is because the outside force, which in this case the act of cradling, is applying more pressure on the lacrosse ball from the outside of the net than gravity is causing on the inside of the net which results in the lacrosse ball staying inside of the net of the lacrosse stick. Newton's first Law of Inertia is put into play because when you have control of the ball the only thing that can change that is either a change of gravity that can be caused by the lack of centrifugal force due to lack of cradling, or another force which in this case would happen to be another player that is applying pressure to you changing your force and affect the force on the ball.
The motion of all the material in the Universe is affected by gravity. Gravity helps the galaxies rotate and the planets in the solar systems orbit. 4. How do galaxies vary? Galaxies vary based on size, composition, and structure, however most all of them are arranged in clusters.
On the contrary to popular belief, objects in orbit do experience gravity. The objects feel weightlessness from freefall, essentially, objects on and around the Earth are always falling to the Earth’s center of gravity, but due to their velocity, the objects always miss crashing to the surface. The required speed to orbit Earth is 28,000 km/h, or 17,500 mph, and any less than this the object would fall back to earth. Rocket Thunderbug will enter orbit at a 90° angle with a velocity of 28,000 km/ h.
This is when the objects are dropped and when the object is in the air, below it is the distance between the object and the ground. Along with, force is when something moves because something is moving something else with its force. If something is being pushed or moved by something like when someone is pushing another person, they would be using the force to push the other person.
