Based on absolute dating, which fossil organism lived for the longest period of time? The shortest?

Answers

Answer 1

Based on absolute dating, the fossil organism that lived for the longest period of time is likely the stromatolites, which first appeared approximately 3.5 billion years ago and can still be found today.

The shortest-lived fossil organisms would be those that only existed for a brief period of time before going extinct.

What is the fossil  about?

Stromatolites are the oldest known fossils, consisting of layered mats of cyanobacteria (blue-green algae) that date back to approximately 3.5 billion years ago. They were widespread throughout the ancient oceans, and their structures can still be found today in certain locations, such as the coast of Western Australia.

Therefore, There are many examples of short-lived fossil species, but one possible example is the dinosaurs known as alvarezsaurids, which existed for a relatively short period of time during the Late Cretaceous period, approximately 85-66 million years ago.

How has urbanization in periphery and semi periphery countries around the world led to the development of mega cities and meta cities ?

Answers

Answer:

I do not think world systems theory explains everything there is to know about the world. The very large cities, mega cities, those having over 10 million population, (a category including meta cities, over 20 million population, as these terms are not rigidly defined), rise up all over the world.

This article lists mega cities with current population estimates.

I do not know who is publishing about World Systems Theory and defining peripheral cities currently. I saw a map from 2000, 20 years ago, during which time China has grown enormously, industrializing, building a nationwide high speed rail network, and is now the nation using the most energy each year. It seems that the definition of periphery nations might need some revising.

It is logical that China and India with their large populations have megacities. And it is logical that other global cities are in that same class, like Tokyo, London, Paris, Buenos Aires, and New York City.

describe what happens to the tectonic plates along a transform boundary during the time between earthquakes.

Answers

Using the theories of tectonic plates, we got that during the time between earthquakes the tectonic plates lock into the place to prevent from sliding causing pressure to build up.

Plates can move past each other in  same plane at a boundary. This type of the boundary is called a transform boundary. This type of the boundary is dominated by strike-slip faulting, although other types of the faulting may be observed, where the two plates slide past each other, earthquakes originate at shallow depths.

Hence, during the time between earthquakes tectonic plates along a transform boundary  lock into the place to prevent from sliding causing pressure to build up.

Explanation:

Describe and compare the three types of scales used by scientists to measure and describe earthquakes.

Answers

the three types of scales used by scientists to measure and describe earthquakes are:

Richter scaleMercalli scaleMoment magnitude scale

Richter scale: Dr. Charles Richter, a seismologist at the California Institute of Technology, created the Richter scale in the 1930s. The amplitude of the greatest seismic wave observed during the earthquake is used to compute the earthquake's Richter magnitude.

Since the Richter scale is a base-10 logarithmic scale, there is no upper or lower limit to the size of an earthquake that can be measured by it. On the Richter scale, 1 represents the smallest earthquake and 10 represents the greatest.

The Richter scale is logarithmic, thus an earthquake with a magnitude of 5.0 will generate shaking 10 times more than one with a magnitude of 4.0.

Mercalli scale: By calculating the impacts of an earthquake on the Earth's surface, the Mercalli scale determines the magnitude of an earthquake.

The Mercalli scale ranks earthquakes on a scale of 1 to 12, with 1 meaning that nothing was felt and 12 denoting complete damage, based on human reactions, natural objects, and man-made buildings.

The Mercalli scale, developed in 1902 by Giuseppe Mercalli, isn't regarded as being as accurate as the Richter scale. This is due to the Mercalli scale's reliance on eyewitness reports, which prevents it from defining the quake's force according to strict and impartial standards as the Richter scale does.

Moment magnitude scale: The Richter scale was replaced in 1979 by the moment magnitude scale.

The moment of the earthquake, which is equal to the stiffness of the Earth times the typical amount of slip on the fault and the size of the region that slipped, serves as the basis for the moment magnitude scale, which compares the energy released by earthquakes.

The U.S. Geological Survey estimates the magnitudes of all contemporary big earthquakes using the moment magnitude scale because it is more precise than the Richter scale in measuring large earthquakes.

Based on your observations of the flute geometries and knowing how these flute casts form, label the sample with the correct flow direction and top/bottom interpretation. (A) Upstream / Bed Top Upstream / Bed Bottom Downstream / Bed Top Downstream / Bed Bottom

Answers

The preserved remains of water running over and eroding sediments are known as flute casts, also known as sole marks.

What does softer sediment do?

Softer sediment must cover the exposed surface and fill in the structures that the water has eroded in order to be preserved. A small dip is swept by the water, with a sharp angle on the upstream side and a lower angle on the downstream side.

Turbidity currents are the most prevalent geologic phenomenon that cause flute castings (underwater sediment slides).

Answers

Answer:

One negative impact of the Industrial Revolution on Great Britain was environmental issues. The rapid industrialization led to the release of pollutants and chemicals into the air, water, and soil, causing significant environmental damage. Factories produced large amounts of waste, which often ended up in rivers, contaminating them and making them unfit for drinking and agriculture. The use of coal for energy resulted in high levels of air pollution, which caused respiratory problems and other health issues for people living in the cities. The Industrial Revolution also led to deforestation, soil erosion, and other forms of environmental degradation. These negative impacts on the environment had long-lasting effects and continue to be a problem today.

what largely determines the level of volcanic and tectonic activity on the galilean moons?

Answers

The level of volcanic and tectonic activity on the Galilean moons is largely determined by their distance from Jupiter and the gravitational forces they experience from the planet.

This is due to a process called tidal heating, which occurs when the gravitational forces exerted by Jupiter on the moons cause them to become elongated and flexed in their orbits.As they move through their orbits, the moons are constantly being stretched and compressed, causing frictional heating of their interiors. This process generates a lot of heat, which can lead to volcanic activity on the moons, as well as tectonic activity due to the formation of new surface features.

Tidal heating is most intense on Io, the innermost of the Galilean moons, which experiences the strongest gravitational forces from Jupiter. This has led to Io being the most volcanically active object in the solar system, with numerous active volcanoes and extensive lava flows covering its surface. While the other Galilean moons are less volcanically active than Io, they still experience some level of volcanic and tectonic activity as a result of tidal heating.

C. Hispanic
D. Unauthorized migrant
E. None of the above

Answers

The specific term used for a person of Mexican descent, born in America, as well as those who immigrated from Mexico and became U.S. citizens is option B "Chicano."

The term "Chicano" emerged during the civil rights movements of the 1960s and 1970s as a self-identifying label for individuals of Mexican descent in the United States. It was used to express a sense of pride, cultural heritage, and resistance against discrimination and social inequality. The term specifically refers to individuals who identify with their Mexican roots while embracing their American citizenship. It encompasses a complex and multifaceted identity that reflects the blending of Mexican and American cultures and experiences.

While "Hispanic" is a broader term that refers to individuals from Spanish-speaking countries or backgrounds, it is not specific to Mexican-Americans. "Bracero" refers to Mexican agricultural workers who were brought to the United States under a guest worker program during World War II. "Unauthorized migrant" is a term used to describe individuals who are living in a country without legal authorization, but it does not capture the specific cultural and historical context of Mexican-Americans. Therefore, the correct term for a person of Mexican descent, born in America, as well as those who immigrated from Mexico and became U.S. citizens is "Chicano."

Due to the following factors, the North-South of India extent is greater than the East-West extent: While the distance between the two longitudes decreases as one gets closer to the poles, the distance between the latitudes remains constant throughout.

Latitudes are equally spaced apart, but as one proceeds from the equator to the poles, the distance between longitudes gets smaller, giving the appearance that the east-west extent is smaller than the north-south extent.

The length of India from Ladakh to Cape Comorin, which is close to Kanyakumari, is 3214 kilometres. India's longitudinal boundaries are 68°7'E and 97°25'E. The length of India from Sir Creek in Gujarat to Chaukan Pass in Arunachal Pradesh is 2993 km.

The magnetosphere of a planet is the region around the planet where the magnetic field is able to deflect the solar wind and other charged particles.

A planet's magnetosphere is the area of space surrounding the planet where its magnetic field interacts with charged particles, such as those carried by the solar wind. The magnetic field of a planet, generated by its core, extends into space and forms a protective shield around the planet. This shield helps to deflect and trap charged particles, preventing them from directly impacting the planet's surface. The magnetosphere plays a crucial role in protecting a planet's atmosphere and surface from the harmful effects of the solar wind.

A mineral is said to be stable if after a longtime it does not convert to a new mineral.

A mineral is an inorganic material or compound that occurs in nature and has a recognizable chemical composition, crystal structure, and physical characteristics. Quartz, feldspar, mica, amphibole, olivine, and calcite are examples of common minerals. Calcium, phosphorus, potassium, sodium, chloride, magnesium, iron, zinc, iodine, chromium, copper, fluoride, molybdenum, manganese, and selenium are among the nutrients that are crucial for good health.

There are numerous ways that minerals can originate. Some form when chemicals escape from hot fluids or when salt water evaporates. Others are created when molten rock or hot gases cool, or when pre-existing minerals are altered by heat or pressure. Atoms in a fluid initially form minerals by migrating randomly.
