Do you think partial melting will occur if there is too much amount of water in the subduction zone?

Answers

Answer:

Water plays a crucial role in the melting of Earth's mantle. ... At oceanic subduction zones, water released by the subducted slab may induce melting of the overlying mantle wedge or even the slab itself, giving rise to arc magmatism, or may evolve into a supercritical fluid.

A fly flaps its wings back and forth 25 times in one second. The period of wing flapping is?

Cells are the building blocks of life, yet atoms and molecules are smaller than cells. Why are cells, not atoms, the basic building blocks of life?

Answers

The basic unit of life has to be a living thing, atoms aren't alive yet they make up cells, which are alive. However, atoms are building blocks of everything. Yet cells themselves are living, therefore are the building blocks of all forms of life.

Atoms are smaller than cells. Yet cells are the building blocks of life because atoms are not living, and living organisms are made up of cells because cells are living components.

What are cells and atoms?

Cells are the basic components of living organisms. Atoms are the basic and smallest unit of matter that is nonliving.

Since atoms do not have life, they cannot be the fundamental building block of life; nonetheless, they do makeup living cells.

Atoms are the fundamental units of matter, nevertheless. However, because cells are living entities in and of themselves, they serve as the foundation for all life.

Thus, cells are larger than atoms. However, as atoms are not alive, cells are the fundamental unit of life, and since cells are living entities, they are the foundation of all living things.

How are combustion,
respiration, and decomposition similar to each
other?

Answers

Answer:

The waste products of carbon dioxide and water are also formed. Combustion, which is the burning of carbon compounds, which are fossil fuels, is often compared to cellular respiration because the two processes are extremely similar. ... It's as if our bodies burn our food for energy.

Combustion, respiration and decomposition are similar to each other because they release carbon dioxide.

Combustion is the reaction that occurs between an oxidizable material and oxygen, which is revealed through flames and generates the release of energy.

The different components that are completely oxidized, gives rise to the formation of liquid water and carbon dioxide and even sulfur dioxide.

Respiration is a gas exchange system with the environment, where a fuel molecule, glucose, is oxidized.

Humans take in oxygen through inspiration and exhale carbon dioxide as a waste product produced by the body.

The decomposition of organic matter is useful for microorganisms for two reasons: as an energy supply for their growth, and as a carbon source for the formation of new cellular material.

Carbon dioxide, methane, organic acids, and alcohols are waste products released in the acquisition of energy.

Therefore, we can conclude that combustion, respiration and decomposition are similar to each other because they release carbon dioxide.

Answers

ok so...

1. The reader knows that the boy is about to break up with his girlfriend, but the girlfriend doesn't know. That is dramatic irony

because  Dramatic Irony appears when the readers know something the character does not know. For example, in scary stories, the reader often knows where the bad guy hides, but the character does not. As the character approaches the hiding spot, the readers may experience heightened suspense due to the dramatic irony.

2.Dave's blood pressure medicine game him a heart attack.  That is

Situational irony.

Situational Irony happens when something happens that the reader does not expect to happen. For example, if someone robs a thief in a story, that portrays situational irony. Readers would not expect a thief who robs others to be the one who gets robbed.

3. "Oh, great! I'm so glad it's raining, and I forgot my umbrella."  That is Verbal irony

Verbal Irony occurs when a character says one thing but means something else. This type of irony is also known as sarcasm. For example, a parent might reveal verbal irony, or sarcasm, by showing up at the door of an extremely messy room and commenting, "I've never seen your room this clean before! You are grounded." Clearly, the parent revealed sarcasm when commenting about the cleanliness of the room.

what is different between leaching and erosion​

Answers

Answer:

Erosion is the natural process by which soil / rock are removed from the Earth's surface by exogenetic processes such as wind or water flow, transported and deposited in other locations. Leaching is the removal of soluble material from soil or other material by percolating water.

Erosion is the natural process by which soil / rock are removed from the Earth's surface by exogenetic processes whereas Leaching is the removal of soluble material from soil or other material by percolating water.

What do you mean by soil erosion?

Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, and animals.

Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.

Removing trees and plants, plowing fields, and overgrazing by livestock disrupts roots that stabilize sediment and soil. These human activities can increase erosion rates 10 to 100 times that of non-human geologic processes.

Using the weather data in Table 1, create a 12-hour general weather forecast for the next day following the data collected.

Questions and Conclusion

1. Write a summary of the weather that occurred during the 24 hours in Table 1.
2. What are the possible sources of error in the weather data?
3. What relationships do you notice between temperature, dew point, humidity, cloud cover, and air pressure? Provide evidence for these relationships from data in Table 1.
4. In conclusion, how did your graphs support or contradict your 12-hour forecast for the following day?
5. Describe additional data you could collect to make your forecast more reliable.
6. What did you learn about weather forecasting by completing the activity(optional to answer, but an idea for something to write as a response would help)

Answers

Explanation:

1. During the day, the earth is heated by the sun. If skies are clear, more heat reaches the earth's surface (as in the diagram below). This leads to warmer temperatures.However, if skies are cloudy, some of the sun's rays are reflected off the cloud droplets back into space. Therefore, less of the sun's energy is able to reach the earth's surface, which causes the earth to heat up more slowly. This leads to cooler temperatures.When forecasting daytime temperatures, if cloudy skies are expected, forecast lower temperatures than you would predict if clear skies were expected.At night cloud cover has the opposite effect. If skies are clear, heat emitted from the earth's surface freely escapes into space, resulting in colder temperatures.However, if clouds are present, some of the heat emitted from the earth's surface is trapped by the clouds and reemitted back towards the earth. As a result, temperatures decrease more slowly than if the skies were clear.When forecasting nighttime temperatures, if cloudy skies are expected, forecast warmer temperatures than you would predict if clear skies were expected.

2. The possible sources of error are human error and misreading the data.

3, As air temperature increases, air can hold more water molecules, and its relative humidity decreases. When temperatures drop, relative humidity increases. High relative humidity of the air occurs when the air temperature approaches the dew point value.

4. When forecasting if cloudy skies are expected, forecast lower temperatures than you would predict if clear skies were expected.

5. A more reliable approach to weather forecasting is known as the steady-state or trend method. This method is based on the knowledge that weather conditions are strongly influenced by the movement of air masses that often can be charted quite accurately.

6. Weather forecasts are made by collecting as much data as possible about the current state of the atmosphere (particularly the temperature, humidity and wind) and using understanding of atmospheric processes (through meteorology) to determine how the atmosphere evolves in the future

Answers

plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. The most common methods are wind, water, animals, explosion and fire. Dandelion seeds float away in the wind.

Answer:

Wind, Water, Animals, and Fire.

Explanation:

Wind moves seeds from one place to another. When the seed gets into the air, it gets pushed by wind to another place. Water moves seeds when seeds fall into water and the water moves the seed downstream, or the water evaporates. Seeds get moved by Animals when, for example, a bird eats seeds then flies to another location, and poops out the seeds. Seeds also get moved by Fire when a forest fire erupts and the seeds fall to the ground after the fire dissipates.

Which of the following can be inferred from the diagram above that shows the dependence of potential Energy on the Internuclear distance between two atoms?

A)The atoms form a bond with a bond length of 25 pm
B)The atoms form a bond with a bond length of 75 pm
с)The net force between the atoms is attractive at 25 pm
D)The net force between the atoms is attractive at 75 pm

Answers

Answer:

A)The atoms form a bond with a bond length of 75 pm

Explanation:

The Morse curve is a plot of potential energy against internuclear distance between two atoms.

When two atoms are far apart, the bond energy is zero, this means that there is no significant interaction between the both atoms. Hence, when two atoms are positioned at infinite distance from each other, they do not interact with each other appreciably. At internuclear distance within the range of atomic diameter, attractive forces predominate between atoms. At shorter distances repulsive forces predominate and the energy of system is quite high. The minimum point in the plot of a Morse curve represents equilibrium between attractive and repulsive forces.

The internuclear distance that corresponds to this minimum point is known as the equilibrium bond length.

For the plot shown in the question, the minimum point occurs at an internuclear distance of 75pm. This corresponds to the bond length of the system.
