Large volcanic eruptions can have an almost immediate effect on Earth's climate. Rather than warming the climate volcanic erupti

ons helps to cool the climate. During the 1900's there were three large eruptions that caused the entire planet to cool down by as much as 1°C. Volcanic coolings persist for only 2 to 3 years because the released aerosols fall out of the stratosphere and enter the lower atmosphere where rain and wind quickly wash them away. Using the model, can you elaborate on the reason a volcanic eruption might cool the climate?

Answer:

Most of the particles spewed from volcanoes cool the planet by shading incoming solar radiation. The cooling effect can last for months to years depending on the characteristics of the eruption. Volcanoes have also caused global warming over millions of years during times in Earth’s history when extreme amounts of volcanism occurred, releasing greenhouse gases into the atmosphere.

Explanation:

Even though volcanoes are in specific places on Earth, their effects can be more widely distributed as gases, dust, and ash get into the atmosphere. Because of atmospheric circulation patterns, eruptions in the tropics can have an effect on the climate in both hemispheres while eruptions at mid or high latitudes only have impact the hemisphere they are within.

Which of the following statements best describes a change that impacted African Americans in the 1950s?
vlada-n [284]

Correct answer:  Court cases challenged the legality of discrimination.

I'll mention key court cases after debunking the other answers in the list.  Truman's desegregation of the armed forces happened already in 1948, and impacted only those in the armed forces, rather than all African Americans.  The suburbs were NOT welcoming toward African Americans, and they remained in living mostly in urban centers.

As to key court cases of the 1950s regarding discrimination:

1950: Sweatt v. Painter and McLaurin v. Oklahoma State Regents.  In these cases, the Supreme Court said segregation of African American students in law and graduate schools was unconstitutional.  This was the start of challenging "separate-but-equal" policies.

1954: Brown v. Board of Education.  Firm decision that "separate but equal" policies were unconstitutional across the education system.  Chief Justice Earl Warren, speaking for the unanimous opinion of the Court, said: “Separate educational facilities are inherently unequal.”  

1955: Brown v. Board II.  The Supreme Court directed that school systems must abolish segregation “with all deliberate speed.”

1956: The Supreme Court affirmed a lower court ruling that the segregation of the Montgomery, Alabama, bus system was illegal.  This was in reference to the bus boycott that had begun with the protest by Rosa Parks.

1958: Cooper v. Aaron.  The Supreme Court upheld the US Court of Appeals (8th Circuit) decision that resistance by local officials and threats of violence in the community did not  justify delaying desegregation.  This followed in the wake of the Little Rock Nine (a group of black students) seeking enrollment in LIttle Rock Central High School.

Why do you think the Turkish government has devoted resources to preserving Christian artifacts in the Hagia Sophia even though
Sophie [7]

Answer:

Because the Turks see the Hagia Sophia as an important artifact. Also, a tradition from the Ottoman times states that Islam is the fulfiller of Judaism and Christianity, and they are all Abrahamic and that no division should take place between the three. So, the Turkish government has taken this duty into their hands and are now preserving the Hagia Sophia for the younger generations of the world to see how the Turkish government and holy Muslims want to keep peace between the religions of the world, and not only that, but how the Turkish government preserved these artifacts to show the later generations of the world intact history.
