Theory of Plate Tectonics
1 Earth is not like the other planets in the solar system. Earth has layers, much like an onion. These layers provide answers to many questions. Earth's crust, the outermost layer, is not entirely one piece. It is broken into sections which resemble a huge jigsaw puzzle. These giant sections are known as plates. They are always on the move, creeping along at a snail's pace. The plates seem to float on top of the mantle, the layer of Earth composed of partially melted rock.
2 Have you ever put together a puzzle? The pieces must fit together perfectly in order to form a picture. Alfred Wegener was a German scientist. Over 100 years ago, he discovered something fascinating about a map of Earth. Wegener realized that the continents seem to fit together like the pieces of a jigsaw puzzle. This giant piece of land was called Pangaea. It existed over 250 million years ago. Over time, Pangaea's tectonic plates slowly drifted apart. These plates in their current positions make our seven continents.
3 Earth's plates are continually being created or recycled. Scientists have studied the ocean floor. They have discovered ridges of mountains along the bottom of the ocean. These ridges form where two plates have started to move apart. Molten rock from the underlying mantle oozes out. Newly formed rock builds up in the space that has been created by the plates' movement. Plate tectonic theory has also helped scientists explain the deep ocean trenches. These deep ocean trenches are areas where plates are being recycled. This can happen where two plates push together. The crust on the edge of one plate is slowly forced under the other. The plate gets pushed back down into Earth's mantle. It will become molten rock again. This type of area is known as a subduction zone. It forms when continental land masses collide with ocean plates, or when two ocean plates collide with each other.
4 On the ocean floor, movement of the plates causes trenches and ridges. Plate movement can do more than that. It can also form mountains on land. When two continental plates push together, there is so much force that the plates buckle. Massive mountain ranges are formed. The friction during crustal movement can sometimes cause earthquakes and tsunamis.
5 The plates on Earth's crust change Earth's surface features in many ways. They had been pieced together in a giant landmass. The plates slowly moved apart to their current locations. The plates will continue to move, forming new rocks and recycling the old. Imagine how a map of Earth might look after another 250 million years of continental drift.

Answer:

1.ansEthylene is at this point still a gas and needs pressure and a catalyst to turn it into polyethylene, a resin. The process by which polyethylene is made from ethylene is known as polymerization. ... Polymerization occurs when a chemical reaction causes molecules to react together to form polymer chains

2.ansPlastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be moulded, extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being lightweight, durable, flexible, and inexpensive to produce, has led to its widespread use. Plastics typically are made through human industrial systems. Most modern plastics are derived from fossil fuel-based chemicals like natural gas or petroleum; however, recent industrial methods use variants made from renewable materials, such as corn or cotton derivatives.[1]

In developed economies, about a third of plastic is used in packaging and roughly the same in buildings in applications such as piping, plumbing or vinyl siding.[2] Other uses include automobiles (up to 20% plastic [2]), furniture, and toys.[2] In the developing world, the applications of plastic may differ; 42% of India's consumption is used in packaging.[2] In the medical field, polymer implants and other medical devices are derived at least partially from plastic. Worldwide, about 50 kg of plastic is produced annually per person, with production doubling every ten years.

The world's first fully synthetic plastic was Bakelite, invented in New York in 1907, by Leo Baekeland,[3] who coined the term "plastics".[4] Dozens of different types of plastics are produced today, such as polyethylene, which is widely used in product packaging, and polyvinyl chloride, used in construction and pipes because of its strength and durability. Many chemists have contributed to the materials science of plastics, including Nobel laureate Hermann Staudinger, who has been called "the father of polymer chemistry" and Herman Mark, known as "the father of polymer physics".[5]

The success and dominance of plastics starting in the early 20th century has caused widespread environmental problems, due to their slow decomposition rate in natural ecosystems. Toward the end of the 20th century, the plastics industry promoted recycling in order to assuage environmental concerns while continuing to produce virgin plastic. The main companies producing plastics doubted the economic viability of recycling at the time, and this is reflected in contemporary plastic collection. Plastic collection and recycling is largely ineffective because of the complexity of cleaning and sorting post-consumer plastics. Most plastic produced has not been reused, either being captured in landfills or persisting in the environment as plastic pollution. Plastic pollution can be found in all the world's major water bodies, for example, creating garbage patches in all of the world's oceans and contaminating terrestrial ecosystems.

Explanation:

3.ansPolyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly(methylene)) is the most common plastic in use today[when?]. It is a polymer, primarily used for packaging (plastic bags, plastic films, geomembranes, containers including bottles, etc.). As of 2017, over 100 million tonnes of polyethylene resins are being produced annually, accounting for 34% of the total plastics market.[5][6]

Many kinds of polyethylene are known, with most having the chemical formula (C2H4)n. PE is usually a mixture of similar polymers of ethylene, with various values of n. It can be low-density or high-density: low-density polyethylene is extruded[verification needed] using high pressure (1000–5000 atm) and high temperature (520 kelvins), while high-density polyethylene is extruded[verification needed] using low pressure (6–7 atm) and low temperature (333–343 K). Polyethylene is usually thermoplastic, but it can be modified to become thermosetting instead, for example, in cross-linked polyethylene.

Why is the use of the inquiry process (or scientific method) a practical way to approach science?

1. The inquiry process is a practical way to approach science because the inquiry process begins by asking questions and moving on from there.  

2. In science it is important to investigate phenomena or certain subjects by posing questions that you would like to answer through the scientific method.

3.  Therefore, the inquiry method is connected because to inquire on a subject requires raising questions which is an essential step in scientific discovery.

Why are scientific theories modified, but seldom discarded?

1.  If a theory cannot explain new evidence or observations then the theory is revised or even thrown

out, but if the theory still explains a wide range of observations and evidence then it is revised

rather than discarded.

2.  it will still hold some value as above as you learn more you tweak your hypothesis to fit the ever expanding amount of info and data you collect and assimilate

3.  The only way they ever go away is if people stop working on them.

Explanation:

Waves are actually energy passing through the water, causing it to move in a circular motion. ... This phenomenon is a result of the wave's orbital motion being disturbed by the seafloor.

The direction a wave propagates is perpendicular to the direction it oscillates for transverse waves. A wave does not move mass in the direction of propagation; it transfers energy.

Answer:

It can affect it by taking away mass and volume. Mass and Volume are the two factors that calculate and make up density

Explanation:

Mass/Volume =Density

If you were to change the mass or volume by changing the size or shape of an object, then this would affect the density.

The piece of evidence changed thinking about the channel on Mars because it shows that the rock was formed next to flowing water as such rock formations exist on Earth and were formed by flowing water.

The geologic process that could have created the channel on Mars is water moving. We can infer from the image that water running across the terrain on Mars created channels similar to those on Earth.

We can claim that the flowing of water creates the channels on Mars because when the water runs for a long period from the same region, it takes the sediments and creates channels.

Answer:

3.07L

Explanation:

Charles law, which describes the direct relationship of the absolute temperature to its volume when the pressure is kept constant will be used in this case. The Charles' law equation is:

V1/T1 = V2/T2

Where; V1 is the volume of the gas at an initial state= 2.33L

V2 is the volume of the gas at a final state= ?

T1 is the absolute temperature of the gas at an initial state= 10°C

T2 is the absolute temperature of the gas at a final state= 100°C

The temperature in degree Centigrade (°C) must be converted to the absolute temperature unit (Kelvin) using:

T(K) = T(°C) + 273.15

T1 = 10°C + 273.15 = 283.15K

T2 = 100°C + 273.15 = 373.15K

To solve for V2 in the above Charles law equation, we make V2 the subject of the formula by saying:

V2 = V1 × T2 / T1

V2 = 2.33 × 373.15 / 283.15

V2 = 869.4395/ 283.15

V2 = 3.0705

Hence, the gas will be expanded to a volume of 3.07L when heated from 10.0°C to 100.0°C.

sugar-water is a mixture not a compound.(homogeneous mixture.)

Explanation:

Compounds are substances formed by the chemical combination of two or more elements. Mixtures are substances formed by physically mixing two or more substances together.

The solution of sugar in water is considered a mixture not a compound because the particles of sugar and water are not completely dissolve nor mixed in a fixed proportion or ratio. hope this helped :)

Answer:

No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.
