What technologies make it possible for us to understand the scale of changes that occurred as a result of the breaking of the glacial dam holding back lake Missoula’s waters

Answers

Answer:

Magnetostratigraphy, optical stimulation luminance dating

Explanation:

The Missoula floods were a glacial lake outburst that was across eastern Washington and created rapture of an ice dam on the Clark rover. According to the US geological survey scientist found evidence of mega 25 major floods were discharged about 10 cubic km per hour. Based on the presence of the multiple interglacial deposits that were embedded in the flood deposits. Techniques like the magnetostratigraphy, optical stimulation luminance dating were used to study and estimate the old floods of the Missoula’s waters. The magnetostratigraphy is a technique used to date the volcanic and sedimentary sequences and thus identify the movement of rocks.

Based on geographical analysis, the technologies that make it possible for us to understand the scale of changes that occurred as a result of the breaking of the glacial dam holding back lake Missoula’s waters is optical stimulation luminance dating.

This is because optical stimulation luminance dating is a technique used in measuring the period in which the last time quartz sediment was exposed to light.

The optical stimulation luminance dating was invented in 1956. It can be used to measured objects that dated back between 0 to 150,000 years.

The optical stimulation luminance dating used magnetic parameters and the process is called Magnetostratigraphy.

Hence, in this case, it is concluded that the correct answer is "optical stimulation luminance dating."

The media has sometimes been jokingly referred to as the “fourth branch of government” in the United States. In a five paragraph essay, explain why this title may or may not be deserved. You may want to think about:

a. The importance of freedom of the press

b. The influence of the media on political discussion

c. The role different forms of media play in citizens’ lives

Answers

Final answer:

The media is often referred to as the "fourth branch of government" because of its important role in the political process in the United States, including freedom of the press, influence on political discussions, and various roles in citizens' lives.

Explanation:

The media is often referred to as the "fourth branch of government" because of its important role in the political process in the United States.

Firstly, freedom of the press is crucial in a liberal society and a healthy democracy. The media acts as a watchdog and maintains transparency, holding the government accountable for its actions.

Secondly, the media has a significant influence on political discussions. It shapes how citizens see and understand the world, as well as the issues and values they perceive as important.

Lastly, the media plays various roles in citizens' lives, serving as an informant, a means for citizens to become informed, and a venue for citizens to announce plans to assemble and protest actions by the government.

the distance along a circle between two points on the circle

Answers

Answers and Explanations:

1. Secant line

There are various different kinds of lines in geometry, and each has its own aspects. A secant line is a line that crosses the shape or graph at exactly two points. Here, we can see that line BC crosses circle A at two points: B and C, so we know it's a secant line.

2. Chord

A line segment that connects two points on a circle without crossing the center is called a chord. Now, if the segment had crossed the center, then it would have been called the diameter.

3. Tangent line

As aforementioned, there are different kinds of lines in geometry. Where a secant line has two intersection points, a tangent has only one. Tangent literally means "touching", and we can see from the picture that the line running through point B is "touching" circle A at exactly one point: B.

Hope this helps!

Final answer:

In circle geometry, the radius is a segment between the center of a circle and a point on the circle, the circumference refers to the distance around a circle, and the arc is the distance along the circle between two points.

Explanation:

The question asked here is about matching the definitions of specific geometric terms with respective images or descriptions. In a circle, the 'segment between the center of a circle and a point on the circle' is referred to as a radius. The 'distance around a circle' is referred as the circumference. Lastly, the 'distance along a circle between two points on the circle' is defined as an arc.

When people move from rural to urban areas, where do they settle first? What are some common issues with these types of settlements?

Answers

Answer:

Due to the adverse conditions of poverty and unemployment in the rural areas, people migrate to urban areas. In urban areas they find increased employment opportunities and better living conditions.

Explanation:

answer above

People migrating from rural to urban areas may settle in different parts of a city based on employment and housing availability. They face challenges such as traffic congestion, insufficient infrastructure, and environmental issues. The economic gap between rich and poor can exacerbate poverty and homelessness in urban settings.

When people move from rural to urban areas, they often settle in areas where they first find employment or housing, which could be in the urban core or surrounding suburbs. The rural-to-urban shift is a migration pattern based on seeking better opportunities such as employment. However, such movements can lead to various urbanization challenges. The initial settlements may lack adequate infrastructure and services, leading to overcrowded living conditions, insufficient sanitation, and limited access to healthcare.

Common issues associated with these types of settlements include traffic congestion, overcrowded schools, and racial tensions. There is also a widening economic gap between the wealthy and the impoverished, leading to higher costs of living in urban areas compared to people's ability to pay. This often results in increased poverty and homelessness. Environmental challenges such as smog, waste management, and ensuring adequate clean water supplies are also significant concerns as the urban population grows.
