I had a quiz in Plate Tectonics and there was 2 questions that are related to this, but not the exact question.

Which material rises from cracks in oceanic crust

-molten rock

Which is the first step in the seafloor spreading process?

-a crack forms in oceanic crust.

When the diaphragm pushes upward, it decreases the volume of the lungs, pushing air out.

Answers

Answer:

d) When the diaphragm pushes upward, it decreases the volume of the lungs, pushing air out.

Explanation:

the relaxed diaphragm muscle is dome-shaped, the contracted muscle is horizontal.

D: When the diaphragm pushes upward, it decreases the volume of the lungs, pushing air out.

This is because the relaxed diaphragm is an upwards dome shape, upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs. Upon exhalation, the diaphragm once again relaxes and returns to its original domelike shape, and air is forced out of the lungs.

In 3 to 5 sentences explain the differences between chemical and physical changes

Answers

Answer:

a physical change in a substance doesn't actually change what the substance is. it remains the same. in a chemical change where there is a chemical reaction, a new substance is formed and energy is either given off or absorbed.

Explanation:

Answer:

The difference between chemical and physical changes is that a chemical change happens whenever there is a change in the molecule of a substance. Chemical changes always make a new substance and could never go back to how it was before. In a chemical change, the energy causes the atoms to break free of their molecules and form different molecules.

A physical change never forms a new substance, for example, if you cut an apple in half it will still be an apple because it did not form a new substance or it does not have mold or anything on it that will not be able to change back to what it was before. The type of physical changes is texture, shape, temperature, and a change in the state of matter.

So the difference between them is that a chemical change can never go to what it was before but a physical change can.

Compare and contrast electric conductors and electric insulators. Give an example of each.

Answers

Answer:

conductor:-

A substance that allows heat to pass through them is known as a conductor.

Example:-All the metals, water, etc.

Insulator:-

A substance that does not allows heat to pass through them is known as an insulator.

Example:-All the nonmetals etc.

Explanation:

In physics, any object or material of any type can be broadly classified into either conductors or insulators based on their current carrying properties. There are also materials knows as semiconductors which have some of the properties of conductors.

Explanation

- A conductor is a type of material that allows the flow of charge in one or more directions through its body.
- Electrical current is generated by the flow of electrons, holes, and positive or negative ions in some special cases.
-On the other hand, an insulator is an object or type of material that do not allow the flow of charge through its body.
-Examples of conductors are metals and metallic wires, whereas examples of insulators are dry wood and plastics.

FINAL ANSWER:

A conductor is any material that allows charge to flow through its body while an insulator does not allow charge to flow through its body.
Metals are examples of conductors and dry wood is an example of an insulator.

Describe the overall pattern of change in average global temperatures from 1860 to 2000.

Answers

Answer: According to the graph, we can actually say that: The global surface temperature average was significantly lower during the period from 1860 to 2000.

What is temperature?

Temperature is actually known as the physical quantity which is usually used to express the degree of hotness and coldness of a matter. It is used to show the thermal energy that matter possesses.

We can see from the graph that the global surface temperature average was significantly lower during the period from 1860 to 2000.

Explanation:

The graph actually demonstrates that the average worldwide surface temperature was substantially lower between 1860 and 2000.

What is global temperature?

In reality, the temperature is a physical measurement that is typically used to represent how hot or cold a substance is. The thermal energy that matter possesses is demonstrated by using it.

The main cause of Earth's warming is the presence of additional greenhouse gases in our atmosphere. Methane and other greenhouse gases like carbon dioxide (CO2) trap heat from the Sun in the Earth's atmosphere. It is typical for our atmosphere to have certain greenhouse gases.

The graph shows that between 1860 and 2000, the average worldwide surface temperature was much lower.

Thus, the graph actually shows that between 1860 and 2000, the average global surface temperature was significantly lower.

HELP ASAP LAST QUESTIONTrue or False: There are situations at the local level that the Governor of the state could legally not address. A. TrueB. False 1 Over the past ten years more than two dozen athletes have died from the medical condition known as heatstroke. Heatstroke occurs when the bodys internal temperature becomes so elevated that its cooling system begins shutting down. Who is most at risk? Surprisingly, it is younger athletes. They often either do not recognize or ignore the warning signs until its too late. To make matters worse, childrens bodies are much less efficient than adults at cooling themselves. A promising new product hopes to end the all too common heatstroke trend. It is called a thermometer pill.2 While it doesnt look much different from the average vitamin capsule, the work it does inside the body is truly amazing. Once ingested these capsules send an internal body temperature reading to a portable device that is not much bigger than an iPhone. A coach or professional trainer monitors the device during practices or events held when temperatures and heat indexes are particularly high. If an athletes body temperature reaches a dangerous level, the monitor immediately transmits an alert. The player is then rushed indoors and placed in an ice bath to rapidly decrease his or her body temperature. This is important, since internal organs can begin shutting down at 105 degrees Fahrenheit.3 While these tiny lifesavers have proven to be effective, they are quite expensive. On average the cost is $50.00 per pill. However, many parents of young athletes say that it is a small price to pay for the peace of mind it gives them on a hot, sultry day.To strengthen the argument for using thermometer pills, the author points out that a person who becomes dangerously overheated faces.A) scarlet fever.B) severe hypothermia.C) an increase in pulse rate.D) organ failure that can lead to death. what happened at the watergate hotel?
