Describe how scientists can use vibrations during earthquakes to figure out if the Earth is made up of liquid or solid deep inside?

Answers

Answer 1

Answer:

Scientists use waves to study the different layers of the earth. Usually, they use seismic waves, which are waves generated by earthquakes or nuclear-test explosions. The seismic waves are bent, sped up, or slowed down, or even reflected when they pass through the earth's layers.

Explanation:

Scientists are able to understand Earth's interior by studying seismic waves. ... Seismic waves travel at different speeds when they pass through different types of material, so by studying seismograms, scientists can learn a lot about Earth's internal structure.

What is agriculture?

The art or science of developing the soil, growing vegetables, and raising livestock is known as agriculture. It involves preparing plant and animal items for human consumption and distributing them to marketplaces. The vast majority of bread and textiles in the world are produced by agriculture.

The parallel effects of big commercial agribusiness in industrialised nations and plantation agribusiness in developing economies can be explained by the fact that both agricultural systems include the merger of farms and ranches and the eviction of rural areas.  Therefore, option B is the correct option.

If the city of Miami is 1.83 meters above sea level,how many years of steady sea-level rise at 4 mm/year will flood the city​

Answers

Answer:

Over 475.5 years

Explanation:

Height above sea level = 1.83 m

Steady sea rise = 4 mm/ year

                          = 0.004 m /year

Let the number of years required for the sea to rise to the height be represented by n.

Thus,

0.004 m/year x n = 1.83 m

n = [tex]\frac{1.83 m}{0.004 m/year}[/tex]

  = 475.5

n = 475.5 years

This implies that, it would take 475.5 years for the sea to rise to that height above sea level. Thus for the city to be flooded, it would take over 475.5 years of steady sea-level rise.

How did the Enlightenment and the Industrial Revolution
lead to conflict in Europe?

Answers

Answer:

Both the Enlightenment and the Industrial Revolution were social processes that led to great changes in the societies of the time. Thus, the Enlightenment led to the adoption of liberal ideologies and greater exercise of rights by the societies of the time, which implied a limit to the powers of the authoritarian governments of the time; While the Industrial Revolution, in turn, led to the adoption of automated production processes that made most of the population begin to reside in urban centers, abandoning rural life.

These two processes, which occurred continuously, greatly modified the social composition of the societies of the time. Thus, European societies became eminently urban, with more combative populations and with a greater awareness of their rights and of the limits to the power of the rulers. This caused conflicts between the liberal sectors and the conservative sectors of the time to begin to occur, giving way to revolutions such as the American Revolution or the French Revolution.

B. Paleo seismology studies have found that the section of the San Andreas Fault that failed during the Fort Tejon quake (segment 3) produces a major earthquake every 135 years, on average. Based on this information, how would you rate the chances of a major earthquake occurring along this section in the next 30 years

Answers

Answer:

22.22%

Explanation:

In this scenario, we can use the information provided as a relational problem. For example, we are told that on average there is a maor earthquake every 135 years. Therefore, we can say that in 135 years theres a 100% probability that a major earthquake will happen. To find the probability that it will happen in 1 year we need to divide 1 earthquake by 135 years.

1 / 135 = .0074

Now we can multiply this value by 30 years to find the probability that a major earthquake will happen within 30 years.

.0074 * 30 = 0.2222  ... multiply by 100 to get percentage value

0.2222 * 100 = 22.22%

Finally, we can see that there is a 22.22% chance of a major earthquake happening in the next 30 years.

Matthias Jakob Schleiden.

Explanation:

The cell theory is one of the fundamental findings in the field of biology, which establishes that all plants and animals, as well as their organs, however varied, are always made up of cells. This theory led to far-reaching conclusions: growth is a process in which more and more cells are formed, which are always formed from cells; forming cells also a fundamental role in reproduction: new individuals always emerge from living cells through cell division. The cell theory was first formulated for plants in 1838 by Matthias Schleiden.
