Dr. Chang is studying seismic waves he notices that seismic waves a tight known as P waves travel faster through the mantle than other than through the outer core what can he conclude from this observation

Answers

Answer 1

Explanation:

Seismic velocities depend on the material properties such as composition, mineral phase and packing structure, temperature, and pressure of the media through which seismic waves pass. Seismic waves travel more quickly through denser materials and therefore generally travel more quickly with depth. Anomalously hot areas slow down seismic waves. Seismic waves move more slowly through a liquid than a solid. Molten areas within the Earth slow down P waves and stop S waves because their shearing motion cannot be transmitted through a liquid.

How will cities need to change to accommodate future population growth?

Answers

Answer:

Cities will need to grow vertically and to become much more self-sustaining.

Explanation:

The global population is growing and it is predicted to grow at least until the end of this century. Even more so, the population of cities is growing at an even faster rate, with people abandoning rural areas and towns and moving into the large urban areas. This has been, is, and will continue to be a huge problem when it comes to handling such a  big number of people living in a very small area.

In order for the large cities to respond to the challenge, they will need to take some measures. One thing that will help with space for living is the vertical growth of the cities instead of horizontal. This would be useful because much more people can live in a much smaller area without any problem, while also preserving valuable fertile soil and natural resources. Another thing that will need to be done is that the cities become as self-sustaining as possible. This would mean basically that the cities produce a large portion of their energy requirenments, every single place in the cities that can be used for growth and production of food to be used, be it the top of the buildings, yards/gardens, smaller spaces near infrastructure, and to have as much greenery as possible so that the city is more pleasant and healthier for living.

Answers

Answer:

The boundaries where the tectonic plates meet are the areas of the world with the most violent natural earthquake activity. When the plates grind against each other along plate boundaries, the rocks are under so much pressure that sometimes they heat up and fold, creating mountain ranges, hills and valleys.

Science Question

Do you think iron oxides found within rocks likely appeared before or after the emergence of cyanobacteria? and explain why

Answers

Answer:

Iron oxides appeared after the emergence of cyanobacteria.

Explanation:

The composition of Earth's atmosphere in the first couple of billions of years of its existence was nothing like the atmosphere of today. This had a big influence on the processes that were taking place, or rather what processes and to what extent could have happened in those conditions. One big difference between the atmosphere then and after is the levels of oxygen.

Until the appearance of cyanobacteria, the oxygen levels in Earth's atmosphere were very low, and the same goes for the oceans. With a lack of oxygen, the process of oxidation was absent as well. The cyanobacteria though managed to produce oxygen, and this was on such a high scale that they changed the composition of Earth's atmosphere and the oceans. Not just that this enabled complex lifeforms to develop, but it also enabled the process of oxidation. Iron oxides for example occurred only after cyanobacteria appeared, and this can easily be seen when dating the oldest iron oxides and compare that age with the appearance of cyanobacteria.

Answers

The correct answer to this open question is the following.

James Hutton, the author of Theory of the Earth (1785), studied the stratification of rocks and concluded that our planet is permanently in a cycle of constant renewal. His theory included the constant erosion of the exposed soil and the rocks due to the elements of nature. New sediments that resulted from this process finally turned into solid forms due to the pressure and the heat of the earth.

Hames Hutton (1726-1797) was a scientist from Scottland, considered by many specialists as the founder of the father of modern Geography. He was a firm believer that by observing the cycles of erosion of the elements of earth, you could understand its history.

What does the cluster of seismic events in Southeast Asia suggest?

Answers

Answer:

Every fault that experienced an earthquake in the past is likely to experience earthquakes in the future. Plate boundaries are of course the most likely places to be struck by earthquakes, but seismic events can also happen within tectonic plates.

In Southeast Asia, the plate boundary between the Indo-Australian and Eurasian plates (i.e. the Sunda Megathrust) is very likely to be hit by earthquakes (and tsunamis). Scientists study the segmentation of the Sunda megathrust and the return times of earthquakes in this subduction zone to mitigate their effects as much as possible.

Explanation:

hope this helps

The cluster of seismic events in Southeast Asia suggests there were earthquakes. Also, there was a tectonic plate moment that was happening. There were various volcanoes that were erupting.

What is a seismic event?

The energy generated by an earthquake travels in pulses through the earth's crust and core, and these tremors, known as shock waves, may be recorded anywhere in the world. This allows scientists to determine the strength of the earthquake.

Earthquakes are very likely to impact the plate border in Southeast Asia where the Indo-Australian, as well as Eurasian plates, meet. In order to reduce the impact of earthquakes throughout this subduction zone, researchers examine the Sunda megathrust's fragmentation and its better prediction. Also, there were volcanoes.
