How many eruptions did the Kraktau have in total? Also, which years did Krakataus' major eruptions happen in?​

Answers

1.

Answer:

The Kraktau had around 50 significant eruptions recorded.

Explanation:

Krakatoa was once a small island of amazing beauty in Indonesia. It was of volcanic origin. The island was destroyed by the 1883 eruption explosion. It is one of the most famous volcanic explosions of all time. Only Rakat part is left of the island.

Eruption list: 1530, 1680-81, 1684, 1883 (Plinian eruption), 1927-30, 1931-32, 1932-34, 1935, 1936, 1937, 1938-40, 1941, 1942, 1943, 1944, 1945, 1946, 1946-47, 1949, 1950, 1952, 1953, 1955, 1958-59, 1959-63, 1965, 1969, 1972-73, 1975, 1978, 1979, 1980, 1981, 1988, 1992-93, 1994-95, 1996, 1997, 1999, 2000, 2001, 2007-8, April 2009-early 2010, Oct 2010 - March 2011, July-Oct 2011, Jan-May, Sep 2012, 2015, 2017, 2018 (22 Dec eruption & tsunami)

2.

Answer:

The major eruptions in Kraktau happened in the period from May to August 1883.

Explanation:

The dark, angry rumble began to spread from Krakatoe in May 1883. A few months later the rumble became even louder. Ships passing by were reporting explosions that were so loud that their eardrums burst. Just after 10am on August 27, 1883, Krakatoa was blown up by one of the largest explosions ever recorded. The sound of the explosion was heard in Australia, at a distance of 3,500 km. The island collapsed on its own and turned to dust. About 19 cubic miles of volcanic material flew into the air. A cloud of dust rose 80 km uphill and then circled the Earth for years, causing summer temperatures to drop and spectacular sunsets around the world. More than 36,000 people were killed. Anak Krakatau has been the site of frequent eruptions since 1927.

What effect does Earth’s spherical shape have on the amount of sunlight that reaches the equator?
A.
The latitudes near the equator receive direct sunlight, which causes a high-pressure system.
B.
The latitudes near the equator receive indirect sunlight, which causes a low-pressure system.
C.
The latitudes near the equator receive direct sunlight, which causes a low-pressure system.
D.
The latitudes near the equator receive indirect sunlight, which causes a high-pressure system.

Answers

C. The latitudes near the equator receive direct sunlight, which causes a low-pressure system.

Explanation:

The spherical shape of Earth has very big influence on the climatic conditions on it. The sunlight is falling at different angles at different places, the air pressure is different, the wind belts are influenced by it, the temperature variations are very large etc.

Near the equator, for example, the sunlight falls at more direct angle. This means that the sunlight is more concentrated, so the surface receives more heat. The temperatures are high because of this all year round, and the air pressure is mostly low, as the warm air is more dispersed and weighs less, and the high evaporation means lot of water vapor which lowers the weight of the air even more.

Final answer:

The Earth's spherical shape affects the amount of sunlight that reaches the equator by creating a high-pressure system due to direct sunlight. This has significant impacts on Earth's climate zones and weather patterns.

Explanation:

The Earth's spherical shape affects the amount of sunlight that reaches the equator in the following way: the latitudes near the equator receive direct sunlight, which causes a high-pressure system. The direct sunlight at the equator warms the air, causing it to rise and creating an area of low pressure. This atmospheric circulation pattern, known as the Hadley cell, is fueled by the intense solar radiation at the equator and plays a key role in the formation of Earth's climate zones and weather patterns.

What is Capital Architecture ?

In architecture, the capital (from the Latin caput, or "head") or chapiter constitutes the uppermost member of a column (or a pilaster). It expands the area of the column's supporting surface by acting as a mediator between the column and the weight pressing down on it.

The capital connects the often square abacus and the typically circular shaft of the column, projecting on each side as it rises to support the abacus. The capital might be convex, as in the Doric order, concave, as in the inverted bell of the Corinthian order, or scroll outward, as in the Ionic order.

All capitals in the classical tradition are based on these three primary forms.

You are told that PA I B) = PBIA). Which statement below must be true?
O A and B are equally likely
O A and B are independent
O PAI B) = 0.5
A and B are dependent​

Answers

Answer:

A and B are equally likely

Explanation:

The conditional probability is defined as follows:

[tex]P(X|Y)=\frac{P(X\cap Y)}{P(Y)}[/tex]

where:

[tex]P(X|Y)[/tex] is the probability for X to occur, given that Y has occurred

[tex]P(X\cap Y)[/tex] is the probability that both X and Y occur at the same time

[tex]P(Y)[/tex] is the probability for Y to occur

Given two events A and B, we have:

[tex]P(A|B)=\frac{P(A\cap B)}{P(B)}[/tex]

and

[tex]P(B|A)=\frac{P(A\cap B)}{P(A)}[/tex]

In this problem, we are told that

[tex]P(A|B)=P(B|A)[/tex]

Which means that:

[tex]\frac{P(A\cap B)}{P(B)}=\frac{P(A\cap B)}{P(A)}[/tex]

Simplifying, we get:

[tex]P(A)=P(B)[/tex]

which means that A and B are equally likely.

Which is the easternmost country of Asia?

Answers

Answer:archipelago

Explanation: archipelago

The easternmost country of Asia is Kiribati. Kiribati is located near the equator and is divided into three island groups: the Gilbert Islands, the Phoenix Islands, and the Line Islands.

Kiribati is an island nation located in the central Pacific Ocean. It is composed of 33 coral atolls and islands, and its easternmost point is the Line Islands group. The Line Islands extend the furthest east in Asia, making Kiribati the easternmost country in the continent.

To illustrate this, the Line Islands include several atolls, such as Tabuaeran (also known as Fanning Island) and Teraina (also known as Washington Island), which are positioned to the east of the International Date Line. This gives Kiribati the distinction of being the country furthest to the east in Asia. Geographical locations and boundaries can sometimes be subject to interpretation or change due to factors like tectonic plate movements or political agreements. However, as of the current understanding of geography, Kiribati is widely recognized as the easternmost country of Asia.

Where is Saint Sebastian?

Answers

Answer:

In spain,

Explanation:

Final answer:

Saint Sebastian refers to artistic depictions of the Christian martyr, with a notable painting by Andrea Mantegna located in the Kunsthistorisches Museum in Vienna, and murals found in a chapel in Lanslevillard, France.

Explanation:

When asked 'Where is Saint Sebastian?' in the context of art, it likely refers to the various depictions of the Christian martyr through art history. One of the most renowned paintings named Saint Sebastian is by Andrea Mantegna, dating around 1480, which shows the saint impaled by arrows and tied to a Greek column.

This particular painting is housed in the Kunsthistorisches Museum in Vienna. Mantegna, an Italian painter who lived from 1431-1506, was known for his use of antiquities, a masterful command of perspective, and his scenes often contained optical illusions.

Moreover, Saint Sebastian murals can be found in a chapel located in the remote Alpine village of Lanslevillard, part of the Haute-Maurienne region in Savoie, France, where the veneration of St. Sebastian was common due to his association with the plague.

Using the map below, explain how to find the longitude and latitude of Mexico City. Be sure to provide the longitude and latitude measurements within your explanation.

Answers

The latitude is 19.4 degrees North, and the longitude is 99.1 degrees West. To find it we have to find the nearest latitude marker, which is 20 degrees North, and the nearest longitude marker, which is 100 degrees West.

What is latitude?

Latitude is a coordinate that specifies the north-south position of a point on the surface of the Earth or another celestial body. Latitude is given as an angle that ranges from 90° at the south pole to 90° at the north pole, with 0° at the Equator.

Lines of constant latitude, or parallels, run east–west as circles parallel to the equator. Latitude and longitude are used together as a coordinate pair to specify a location on the surface of the Earth.

The term latitude normally refers to the geodetic latitude as defined below. Briefly, the geodetic latitude of a point is the angle formed between the vector perpendicular or normal to the ellipsoidal surface from the point, and the plane of the equator.

In celestial navigation, latitude is determined with the meridian altitude method.

Final answer:

To find the latitude and longitude of Mexico City, locate it on the map, use the horizontal lines for latitude (north-south position) and vertical lines for longitude (east-west position). Mexico City's approximate coordinates are 19.432608 N (latitude) and -99.133209 W (longitude), which can be determined using the NASA Latitude and Longitude Finder.

Explanation:

To find the latitude and longitude of Mexico City using a map, first locate Mexico City on the map. Latitude lines run horizontally across the map and are used to specify the north-south position of a location on the Earth's surface. Longitude lines run vertically from the North Pole to the South Pole and are used to specify the east-west position. Mexico City is in the northern hemisphere, so its latitude will have a 'N' for north after the number. It is west of the Prime Meridian, so its longitude will have a 'W' for west.

Using the NASA Latitude and Longitude Finder or a similar tool, you would input 'Mexico City' into the search function. The resulting coordinates should approximately be:

Latitude: 19.432608Longitude: -99.133209

These numbers represent the latitude and longitude of Mexico City, where the first number is the latitude (N for north of the Equator) and the second is the longitude (W for west of the Prime Meridian).

It is essential to share and discuss your findings to ensure accuracy and understanding of the geographical location.

also began dropping dramatically.​

3. political situations improved in several nations

Explanation:

I believe these two answer are the correct ones, because when the war (WWI) in America was over, many politics and the president were more focused on the well being of it citizens. They passed laws and improved social security for citizens which means medical care for the disable, poor, orphans, and the elderly.

Hoped this helped. :)

Final answer:

The decline in death rates after the 1950s can be credited to advancements in medical care, including vaccinations and antibiotics, significant improvements in food production, and enhanced public health infrastructure, leading to better hygiene and sanitation.

Explanation:

The decrease in death rates after the 1950s can be attributed to several advancements. Firstly, improvements in medical care played a crucial role. The introduction of vaccinations and antibiotics prevented and cured many infectious diseases, respectively, saving countless lives. Secondly, advancements in food production methods during the Green Revolution led to an increased food supply, reducing death rates due to malnutrition or starvation. Lastly, enhancements in public health infrastructure, such as better water supplies and sewage systems, vastly improved overall public health and hygiene, contributing to lower death rates.

The impact of these factors was so profound that by 1965, the death rate among developed nations had reduced to about one-quarter of its 1800 level. Similarly dramatic declines in death rates were observed in developing nations, though birth rates remained relatively unchanged there, resulting in higher population growth rates. Technological advancements from the Industrial Revolution also bolstered the improvements in food distribution and public health.

Answer:

Increased ocean temperature

Explanation:

Coral reefs provide shelter and protection to many aquatic organisms. It is also a source of protection against coastline erosion.

Climate change results in increased temperature of the oceans which in turn increases the level of carbon dioxide. The increase in carbon dioxide in the oceans will amount to the coral reefs to consume more of the algae that provide it with oxygen in its body. This quick consumption of the algae results to death of coral reefs by bleaching.

D. Increasing ocean temperatures
