A sample of the lava flow within the outcrop has 707 Uranium-235 atoms, and 293 Lead-207 atoms. How old is the lava flow?
Answer:
The lava flow is approximately 351.925 million years.
Explanation:
We find that atoms of Uranium-235 decays and turns into Lead-207 and that half-life of the former one is [tex]703.8\times 10^{6}[/tex] years. The initial amount of Uranium-235 is the sum of current atoms of Uranium-235 and Lead-207. The decay of isotopes is modelled by the following ordinary differential equation:
[tex]\frac{dn}{dt} = -\frac{n}{\tau}[/tex] (Eq. 1)
Where:
[tex]\frac{dn}{dt}[/tex] - Rate of change of the amount of Uranium-235 atoms, measured in atoms per year.
[tex]n[/tex] - Current amount of Uranium-235 atoms, measured in atoms.
[tex]\tau[/tex] - Time constant, measured in years.
The solution of this differential equation is described below:
[tex]n = n_{o}\cdot e^{-\frac{t}{\tau} }[/tex] (Eq. 2)
Where:
[tex]n_{o}[/tex] - Initial amount of Uranium-235 atoms, measured in atoms.
[tex]t[/tex] - Time, measured in years.
In addition, we can calculate the time constant in terms of the half-life:
[tex]\tau = \frac{t_{1/2}}{\ln 2}[/tex] (Eq. 3)
If we know that [tex]n_{o} = 1000\,atoms[/tex], [tex]n = 707\,atoms[/tex] and [tex]t_{1/2} = 703.8\times 10^{6}\,yr[/tex], then the age of the lava flow is:
From (Eq. 2):
[tex]t = -\tau \cdot \ln \frac{n}{n_{o}}[/tex]
By (Eq. 3);
[tex]\tau = \frac{703.8\times 10^{6}\,yr}{\ln 2}[/tex]
[tex]\tau \approx 1.015\times 10^{9}\,yr[/tex]
[tex]t = -(1.015\times 10^{9})\cdot \ln \frac{707\,atoms}{1000\,atoms}[/tex]
[tex]t \approx 351.925\times 10^{6}\,yr[/tex]
The lava flow is approximately 351.925 million years.

Upwelling, the rising of water from deeper layers of the ocean, is a wind-induced movement that brings ________ water to the surface.
Answer:
Upwelling, the rising of water from deeper layers of the ocean, is a wind-induced movement that brings cold and nutrient rich water to the surface.
Explanation:
Marine resurgence is an oceanographic phenomenon that occurs when subsurface waters rise. These waters consist of a large amount of nutrients and have a lower temperature than surface waters, becoming colder. This phenomenon generally occurs in areas where primary production is high, or when there is strong fishing activity in the region.
Why don't S shock waves get recorded on seismographs all over the globe after an earthquake?
A. S shock waves fade out as they travel through the earth.
B. All shock waves overlap so much that S waves can't be seen on the seismograph
C. S waves travel in the opposite direction, so they are never recorded.
D. S waves are stopped by the outer core of the earth.
Answer:
A. S shock waves fade out as they travel through the earth.
Explanation:
Seismic waves lose a great number of their energy when they travel over long distances so after an earthquake, they are not recorded on the seismograph.
S waves don't get recorded on seismographs all over the globe after an earthquake because they fade out as they travel through the earth.

Why do Earth, Mars, and Venus lack any hydrogen and helium in their atmospheres?
Their gravitational pull is too strong.
They spin too quickly on their axes.
Their masses are too large.
Their gravitational pull is too weak.
Answer:
Their gravitational pull is too weak.
Explanation:
Earth, Mars and Venus are terrestrial planets that used to have hydrogen and helium in their atmospheres. However, these light elements were lost over time as they evaporated. This is primarily due to the planets' having weak gravitational pull when compared to the other bigger planets like Jupiter, Saturn and Uranus and the planets' warmer temperature that results to having a thin atmosphere.
On the other hand, the bigger planets have large masses and are cold enough to prevent both hydrogen and helium molecules from escaping the atmosphere.
Answer:
Their gravitational pull is too weak. Correct!
Explanation:
The terrestrial planets all have low mass, so the gravity they produce is much weaker than the sun or the Jovian planets. The gravity exerted by these planets is too weak to hold hydrogen or helium in the atmosphere.

In the 1850s, an international conference accepted the Greenwich meridian, located in London, England, as the standard location of the prime meridian. What was the main effect this decision had on cartography? O A. Maps included a longitude line marked as the prime meridian. B. Maps were based with 0° longitude placed in London, England, rather than based on the nationality of the cartographer. C. Maps included the prime meridian to diminish the effect of distortions of land areas to the far north and south. D. Maps were now centered on the prime meridian at 0° longitude
Answer:
D.
Explanation:
Its not c, maps didn't necessarily state there was a prime meridian, so i dont think it is a, and I don't think maps were ever based around a nation, they were made to see certain areas not to put their nation in the middle.

How have human systems and political systems shaped Central America and the Caribbean?
Answer: This quesiton can cover many topics, but if you want the most basic ones it could be transportation, culture, and the form of government
Explanation:
Many of the countries are still developing, and because of this, their governments are corrupt as heeeeeeckk. Presidents and government officials tend to steal money from its people a lot, through everything. This is because of very weak law enforcement and the limiting of powers. This causes for the economy and education in the country to go down. This also causes more poverty, which means less people go to school and get careers. This is one of the big reasons why I appreciate the free education in the U.S., we are very privileged and we should be grateful for the things we have that others wish to obtain. :(
The Panama Canal improved transportation a thousand times better. People from California or Asia had to go around South America through boat, and this took about 12 - 14 months. When the canal was built, the time decreased to about 3 months (which is a lottt). It also decreased the deaths from starvation or hitting icebergs at the south.
The cultures across the countries are very different due to different conquerors during the Colonization Era back in the 17th century. Spanish, British, French, Dutch, etc. conquered many parts of land, so that’s why Mexico speaks Spanish while its neighboring country, Belize, speak English. The culture diversity is very high in the Americas.

The map below shows the locations of what type of boundary?
a. transform
b. collisional
c. convergent
d. divergent
Answer:
The red lines on this map show us divergent plate boundaries.
Explanation:
The tectonic plates are in constant movement, and this results in interactions between them. At some places the plates collide, at other places slide past each other, and at some move away from each other. The last ones are the places where there is a divergent plate boundary.
The divergent plate boundaries can occur in the ocean or on land. When they occur in the ocean, they form an underwater mountain range, known as a mid-ocean ridge, which is volcanically highly active. An example of this is the mid-Atlantic ocean ridge. When these boundaries occur on land, they form rifts, where the crust starts to crack, a gap opens up, and gradually widens. An example of this is the Great Rift Valley of Africa.

D. divergent

Using the rule of 70 for doubling time, in how many. years will the population of mali double if its present rate of natural increase is 3.6, assuming all other indicators stay. constant
A. 20 years
B. 40 years
C. 60 years
D. 80 years
E. 100 years
The time it will take for the population of mali to double is 20 years. Which is the correct answer would be an option (A).
What is the rule of 70 for doubling time?The rule of 70 for doubling time is defined as the time it will take for your investment to double and is calculated by dividing your growth rate by 70.
For example, if your mutual fund has a four percent growth rate, divide 70 by three. Thus, the doubling time is 17.5years because 70 divided by three is 17.5.
We have to determine using the rule of 70 for doubling time, in how many. years will the population of mali double if its present rate of natural increase is 3.6.
We have been given that the present rate of natural increase is 3.6.
According to the rule of 70 for doubling time,
70 divided by the growth rate of 3.6
⇒ 70/3.6
⇒ 19.44 ≈ 20
Therefore, the time it will take for the population of mali to double is 20 years.

What is the Judaism distribution?
Answer:
Judaism is mostly found in the USA and Israel, and in a smaller scale in some of the European and South American countries, though there are in other countries around the world.
Explanation:
Judaism is one of the oldest religions in the world that has managed to survive in modern times. It is the first of the Abrahamic religions and it has been the basis for the formation of Christianity and Islam later in history. The followers of this religion have been the subject of persecution and genocide multiple times throughout history, which has led to stagnation of the number of followers or drop of it.
Nowadays, the USA has the biggest number of Jews, around 12 million, while Israel, the only Jewish dominated country, has around 6.5 million Jews. Only three other countries have over half a million Jews and those are France, Canada, and Russia. Other countries where there are Jewish communities that number more than 100,000 people are the West Bank, UK, Argentina, Germany, Ukraine, Brazil, Australia, and Hungary.
