what is the overall conclusion reached by mark lawrence and his coauthors in their review of the efficacy of major negative emissions technologies of carbon capture, aerosol injections, and afforestation? (climate crisis, chap. 3)

Answers

The.overall conclusion reached by mark lawrence and his coauthors in their review of the efficacy of major negative emissions is A. All of them can make a significant difference in reversing global warming

How to illustrate tye information?

By injecting the captured greenhouse gases back into the earth, carbon capture and storage (CCS) involves capturing, transporting, and storing greenhouse gas emissions from fossil fuel power plants, energy-intensive industries, and gas fields.

Long-term changes in temperature and weather patterns are referred to as climate change. Although these changes may be natural, human activities have been the primary cause of climate change since the 1800s, primarily as a result of the burning of fossil fuels (such as coal, oil, and gas), which results in the production of heat-trapping gases.

The gradual increase in the planet's surface temperature is known as global warming. Although this warming trend has been present for a while, the burning of fossil fuels over the past century has greatly accelerated its pace.

The first and last terms of an AP are 7 and 49 respectively. If sum of all terms is 420, find its common difference.​

Answers

 Common Difference = 3 

Step-by-step explanation:

Given:

First term of AP is 7.

Last term of AP is 49.

Sum of all terms of AP is 420.

To Find:

What is the common difference of the AP ?

Solution: Let the common difference and number of terms of AP be d and n respectively.

a = first term = 7

d = common difference

l = last term = 49

Sⁿ = sum of all terms = 420

As we know that , Sum of n term of an AP is

★Sⁿ = n/2 × ( a + l ) 

⟹ 420 = n/2 ( 7 + 49 )

⟹ 420 × 2 = 56n

⟹ 840/56 = n

⟹ 15 = n

So the given AP series contains 15 terms and last term of AP will be given by -

➙ a + (n – 1)d = 49

➙ 7 + (15 – 1)d = 49

➙ 14d = 49 – 7

➙ d = 42/14

➙ d = 3

Hence, the common difference of AP series is 3.

Why do you think it was so important to science when Alfie Wegener and Harry Hess has proved their theories of continental drift and seafloor spreading

Answers

Alfred Wegener produced evidence in 1912 that the continents are in motion, but because he could not explain what forces could move them, geologists rejected his ideas. Almost 50 years later Harry Hess confirmed Wegener's ideas by using the evidence of seafloor spreading to explain what moved continents.

Alfred Wegener delivered proof in 1912 that the landmasses are moving, but since he was unable to make sense of what powers could move them, geologists dismissed his thoughts.

What is theory of continental drift?

Continental drift portrays perhaps of the earliest way geologists thought mainland moved over the long haul. Today, the hypothesis of continental drift has been supplanted by the study of plate structural.

Today, we realize that the landmasses lay on monstrous sections of rock called structural plates. The plates are continuously moving and connecting in a cycle called plate tectonics. The mainland are as yet moving today.

The absolute most unique destinations of structural movement are ocean bottom spreading zones and monster break valleys. During the time spent ocean bottom spreading, liquid stone ascents from inside the Earth and adds new ocean bottom (maritime covering) to the edges of the old. Ocean bottom spreading is most powerful along goliath submerged mountain ranges known as mid-sea edges.

Therefore In 1912 a German meteorologist named Alfred Wegener presented the principal point by point and extensive hypothesis of continental drift.

A primary air pollutant is a pollutant that is directly emitted into the atmosphere from a source. Examples of primary air pollutants include carbon monoxide, sulfur dioxide, nitrogen dioxide, and particulate matter.

Primary air pollutants are released into the atmosphere from sources such as vehicle exhaust, power plants, and industrial processes. The pollutants can travel long distances before being deposited and dispersed into the environment.

A secondary air pollutant is produced in the atmosphere when two or more primary pollutants interact. Examples of secondary air pollutants include ozone, aerosols, and acid rain.

Secondary air pollutants are created in the atmosphere through a variety of chemical reactions. These reactions involve the oxidation of primary pollutants and the formation of new compounds. For example, nitrogen dioxide and volatile organic compounds react in the presence of sunlight to form ozone.

compare and contrast hurricanes and mid-latitude cyclones.

Answers

Hurricanes and mid-latitude cyclones are both types of large-scale weather systems that exhibit cyclonic circulation patterns, but they differ in their characteristics and geographical locations.

Let's compare and contrast hurricanes and mid-latitude cyclones.

Hurricanes: Hurricanes are tropical cyclones that form over warm water. They typically occur in the Atlantic and Eastern Pacific Oceans. They are characterized by a low-pressure center surrounded by thunderstorms, which results in high winds and heavy rainfall. The winds in a hurricane are typically stronger than those in mid-latitude cyclones. Hurricanes are measured on the Saffir-Simpson Scale and are categorized from 1 to 5 based on their wind speed. The strongest hurricanes are called Category 5 hurricanes.

Mid-latitude cyclones: Mid-latitude cyclones, also known as extratropical cyclones, are low-pressure systems that form between 30 and 60 degrees latitude. They are associated with cold fronts and warm fronts that bring changes in temperature and precipitation. They occur in the mid-latitudes, including Europe and North America. They are typically weaker than hurricanes, but they are larger and can last for days. They are also responsible for the formation of tornadoes.

X percentage =

G percentage =


%

Answers

To determine the values of the interest rate (R) and the long-run shares of spending in GDP, we can use the given equations. Let's solve them step-by-step:

1. Equation for consumption (C/Y*):
  C/Y* = 0.7 - 0.2(R - 0.05)
2. Equation for investment (I/Y*):
  I/Y* = 0.2 - 0.8(R - 0.05)
3. Equation for exports (X/Y*):
  X/Y* = 0 - 0.95(R - 0.05)
4. Equation for government spending (G/Y*):
  G/Y* = 0.2

Now, let's solve for the values:
1. Solve for R (interest rate):
  We'll use the equation for consumption (C/Y*):
  C/Y* = 0.7 - 0.2(R - 0.05)
Rearranging the equation:
  0.2(R - 0.05) = 0.7 - C/Y*
  0.2R - 0.01 = 0.7 - C/Y*
  0.2R = 0.7 - C/Y* + 0.01
  0.2R = 0.71 - C/Y*
  R = (0.71 - C/Y*) / 0.2

2. Solve for the long-run share of consumption (C percentage):
  C percentage = C/Y* * 100
  Substitute the value of C/Y* from equation 1 into this equation.
3. Solve for the long-run share of investment (I percentage):
  I percentage = I/Y* * 100
  Substitute the value of I/Y* from equation 2 into this equation.
4. Solve for the long-run share of exports (X percentage):
  X percentage = X/Y* * 100
  Substitute the value of X/Y* from equation 3 into this equation.
5. Solve for the long-run share of government spending (G percentage):
  G percentage = G/Y* * 100
  Substitute the value of G/Y* from equation 4 into this equation.

Please provide the values for C/Y*, I/Y*, and X/Y* in order to calculate the long-run shares of spending in GDP.

Write all of the different spheres and how they affect weather and climate?

The hydrosphere refers to all of the water on the planet, including oceans, lakes, and rivers, and it can affect weather by releasing moisture into the atmosphere. The biosphere includes all living organisms, which can affect the atmosphere and hydrosphere through processes like photosynthesis and respiration. The lithosphere refers to the solid Earth, including rocks and soil, and can affect the atmosphere and hydrosphere through processes like erosion and volcanic activity.

What are air masses and how do they affect weather?

Air masses are large bodies of air that have similar temperature and humidity characteristics. They can be classified as either continental or maritime, depending on whether they form over land or water.

The interaction of different air masses can cause changes in weather patterns, such as the formation of storms or the onset of cold fronts. The movement of air masses across different regions can also bring changes in temperature and precipitation.
