Researchers have been studying how emissions from both volcanoes and human activities, such as the burning of fossil fuels, impact the atmosphere. Both types of emissions contribute to the total CO2 levels in the atmosphere. Graph 2 shows that atmospheric CO2 levels have been steadily increasing over time. This increase in CO2 levels has been linked to the increase in global surface temperatures.
Explain why the total mass of carbon must be decreasing in a different step of the slow carbon cycle based on the on the increase in atmospheric CO2.
Answer:
The total amount of carbon in the world is not changing. Because matter is
conserved in all processes and reactions, carbon must decrease in one place if it increases in another.

Carbonic acid is a mixture of
Answer:
a compound of the elements hydrogen, carbon, and oxygen. (also carbonic acid is a compound not a mixture ^-^)
Explanation:
hope this helps dude
According to the concept of solubility, carbonic acid is a mixture of water and carbon dioxide.
Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.
The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.
A mixture of water and carbon dioxide under high temperature and pressure forms carbonic acid as it is highly soluble,thus carbonic acid is a mixture of water and carbon dioxide.

this is science.
Answer:
There is solid proof that global warming is increasing and getting worse by t he day. The ice caps slowly melt more and more each year due to this which is a proven fact. On top of that, it has been proven that carbon emission by humans is bad for the environment and it helps increase the problem of global warming by weakening our atmosphere. As for the cold days, just because we have global warming doesn't mean the earth weather wont be cold. global warming is something that slowly happens and over time the temperature global has actually been increasing at a not very notice able pace.
Explanation:
Yes, climate is changing because of the human activities which are causing harm to the environment causing global warming.
What is global warming?Global warming is the long-term warming of Earth's climate system that has been seen from the pre-industrial period (between 1850 and 1900) as a result of human activity, principally fossil fuel combustion, which raises heat-trapping greenhouse gas levels in the atmosphere.

Defining Emotional Appeal
An emotional appeal is used to sway the emotions of an audience to make them support the speaker’s argument.
LEARNING OBJECTIVES
Break down the components that make up an emotional appeal
KEY TAKEAWAYS
Key Points
Pathos represents an appeal to the emotions of an audience.
An emotional appeal uses the manipulation of the emotions rather than valid logic to win an argument.
Emotional appeal is a logical fallacy, whereby a debater attempts to win an argument by trying to get an emotional reaction from the opponent and audience.
In debating terms, emotional appeals are often effective as a rhetorical device, but are generally considered naive or dishonest as a logical argument, since they often appeal to the prejudices of listeners rather than offer a sober assessment of a situation.
Key Terms
logical fallacy: A fallacy; a clearly defined error in reasoning used to support or refute an argument, excluding simple unintended mistakes.
Emotional Appeal Defined
Pathos represents an appeal to the audience’s emotions. Pathos is a communication technique used most often in rhetoric (where it is considered one of the three modes of persuasion, alongside ethos and logos), and in literature, film, and other narrative art.
Emotional appeal can be accomplished in a multitude of ways:
By a metaphor or storytelling, common as a hook
By a general passion in the delivery
By an overall emotion
By the sympathies of the speech or writing as determined by the audience
The pathos of a speech or writing is only ultimately determined by the audience.
The Purpose of an Emotional Appeal
An emotional appeal is directed to sway an audience member’s emotions and uses the manipulation of the recipient’s emotions rather than valid logic to win an argument. An emotional appeal uses emotions as the basis of an argument’s position without factual evidence that logically supports the major ideas endorsed by the presenter. In an emotional appeal, persuasive language is used to develop the foundation of an appeal to emotion-based arguments instead of facts. Therefore, the validity of the premises that establish such an argument does not prove to be verifiable.
A US soldier holds his daughter and his son.
Emotional Appeal: A picture like this could be used as an emotional appeal for a charity campaign to increase funding for soldiers’ families.
Emotional appeal is a logical fallacy, whereby a debater attempts to win an argument by trying to get an emotional reaction from the opponent and audience. It is generally characterized by the use of loaded language and concepts (God, country, and apple pie being good concepts; drugs and crime being bad ones). In debating terms, emotional appeals are often effective as a rhetorical device, but are generally considered naive or dishonest as a logical argument, since they often appeal to the prejudices of listeners

Students begin to measure the speed of a ball rolling down a ramp. The graph below shows their results.
Answer:
Your answer to your current question is D.20!
Explanation:
If the ball is rolling down from a ramp, it should start at the top, which is 20, then it rolls down to the bottom. But since the ball starts from the top, 20 is the speed since that number is at the top as well, showing what the speed measurement is.

Increase the brightness of the light for the colors red, yellow, orange, and green. What effect did the brightness of the light have on the metal?
(science)
make me brainliest
Explanation:
The observations are as follows: Initially with the plates in the dark, no electrons pass between the plates and no current flows. As we shine light on the plates, going from low energy red to high energy blue, suddenly current begins to flow. How?
Einstein explained the result be describing the light waves as packets of energy. He called the packets of energy photons. Each photon has a specific energy, the shorter the wavelength, the higher the energy. When a high-energy photon hits the plate (such as a green or blue), the photon has enough energy to knock out an electron and then the electron, being negative, will fly to the positive side. At this point, current flows.
The lower energy photons are unable to know out the electrons and no energy can flow.
The exciting thing to note is the treatment of energy as a particle or a packet, it is consistent with the fact energies are not additive. If we can bump electrons with light at 600 tera-hertz , we can�t just use 300 tera-hertz for twice the time and still expect to bump electrons.
What if the photon has greater than the threshold energy required to pop out an electron? The extra energy just goes into the kinetic energy of the electron. This relationship can be described by the following equation.
hf = w + KE
where hf is the energy of the photon.
w is the energy required to bump an electron.
KE is the kinetic energy of the electron.
If the photon has less energy than w, no electron is emitted.

How do water, wind, and thermal energy from the sun move about the earth's surface?
Molecules move more quickly because the sun's light energy transforms into heat energy on the planet. While cooler polar air and water travel away from the poles and towards the equator, warm air and water molecules rise and move in the opposite direction.
What is light energy ?The capacity to make different forms of light visible to human sight makes light energy a sort of kinetic energy. Light is referred to as an electromagnetic radiation that is produced by hot things like the sun, lasers, and lightbulbs. Photons, which are tiny energy packets, are present in light.
Water temperature, biological activities and plant photosynthesis and development are all impacted by light energy.
The air is heated by the sun, and warm air rises. The colder air from the surroundings is forced to enter to replace the rising heated air. The result of this is the wind. Ocean currents function similarly.
Thus, Molecules move more quickly because the sun's light energy transforms into heat energy on the planet.
