If Earth were flat instead of curved, how would that affect temperatures from pole to pole? Explain how the range of temperatures at noon at different latitudes on a cube-shaped planet would compare to temperatures on our spherical Earth.

Answers

If the earth were flat, the sun would revolve above the surface and the sun is much bigger than earth, the earth would have burnt up.

If the earth were cubic, two faces would be the pole and the other four faces will get the temperature change.

What is flat earth theory?

Flat earth theory is a disproven theory, which says that earth is flat or disc shaped.

Many ancient cultures believed that the earth is flat, such as Greece, Hellenistic period, Iron Age, etc.

Thus, if the earth were flat, the sun would revolve above the surface and the sun is much bigger than earth, the earth would have burnt up.

If the earth were cubic, two faces would be the pole and the other four faces will get the temperature change.

Final answer:

If Earth were flat instead of curved, temperatures from pole to pole would be more uniform. On a cube-shaped planet, the range of temperatures at noon at different latitudes would be smaller compared to our spherical Earth.

Explanation:

If Earth were flat instead of curved, the temperatures from pole to pole would be more uniform. On a flat Earth, the angle at which sunlight hits the surface would be the same at all latitudes, resulting in similar temperatures. In contrast, on our spherical Earth, the curvature causes sunlight to hit the poles at an oblique angle, resulting in colder temperatures compared to the equator.

On a cube-shaped planet, the range of temperatures at noon at different latitudes would be smaller compared to our spherical Earth. This is because the cube's flat surfaces would not have the curvature that causes temperature variations. Each face of the cube would receive the same amount of direct sunlight, resulting in similar temperatures across the planet.

What is a coordinate pair?

A coordinate pair, often referred to as an ordered pair, is a fundamental concept in mathematics, particularly in geometry and graphing. It consists of two numerical values or coordinates that specify a unique location or point in a two-dimensional Cartesian plane.


The first value represents the horizontal position and is known as the x-coordinate, while the second value represents the vertical position and is called the y-coordinate.

These pairs of numbers allow precise location identification, making them vital in various applications like plotting graphs, navigation, and defining geometric shapes. Coordinate pairs are used to determine the position of points, lines, and objects, providing a universal system for representing spatial data.

Explanation:

Describe the different climate regions of Eastern Europe (North, Southern, and Central) and how the climate affects life in these places (basically, give one example of how people live in each region, use the lessons for examples-Remember that weird fact about Polish seasons).

Answers

Answer:

Polar air masses derived from areas close to Iceland and tropical masses from the Azores bring, respectively, very different conditions of temperature

Explanation:

Final answer:

Eastern Europe features a variety of climates, from the sub-arctic regions of Scandinavia, the cold snowy climates of central areas like Poland to the humid-subtropical in southern areas around the Mediterranean. These climates affect daily life, from fishing in ice-free Norwegian waters, constructing homes to withstand snowy Polish winters, to farming in the wet, agricultural lands in South-Eastern Europe.

Explanation:

The different climate regions of Eastern Europe consist of the northern, southern, and central areas, each with distinct climates and lifestyles.

Northern Eastern Europe

In northern Scandinavia, the climate is sub-arctic and arctic, with short, cool summers and long, bitter winters. An unusual aspect of this region is the coastal area of Norway which remains ice-free throughout the winter due to the warming effects of ocean currents. The traditional lifestyles here often involve fishing, which is viable year-round along the coast.

Central Eastern Europe

Moving inland to places like Poland, the climate becomes a cold, snowy winter climate with hot, wet summers in the Alpine regions. This climate variation leads to a unique pattern of seasons in Poland, where winters are exceptionally snowy, affecting how people build and heat their homes.

Southern Eastern Europe

In southern regions, such as northern Italy through to Serbia, the humid-subtropical climate is prevalent, with hot summers and cool winters. Agriculture flourishes in these areas due to the high year-round precipitation, with farming being a common way of life.

Climate Influence on Life

Each climate region in Eastern Europe distinctly shares some parallels with U.S. climates, influencing how people live. For example, the eastern steppe in Ukraine is known for agricultural productivity despite extreme temperature swings similar to the U.S. Great Plains.

Area of triangle 2 = square units

Area of triangle 3 = square units

Area of trapezoid = square units

Answers

Answer: The correct answers in order are: 256, 24, 16, 96, 120

Explanation:

I completed this assignment

The area of the rectangle from the points is, 256 and the area of triangle 1 is 6 and triangle 2 is 16.The area of triangle 3 is 96.72 and area of trapezoid is 2 square units.

What is area ?

The area of each geometrical shapes will be different based on their sides, heights etc. The area of a rectangle is length × breadth.

Given length  points of rectangle = (4, 4), (4, 20),

length = √(4-4)² +(20-4)² = 16

width points = (20, 20), and (20, 4)

w = √(20-20)² +(20-4)² = 16

the area = 256 square units.

The coordinates of triangle 1 = (4, 14), (4, 20), (12, 20)

a = √(4 - 4)² +(20-14)² = 6

h = √(12-4)² +(20-20)² = 6

area = 1/2 bh

area = 1/2 (36) = 18 square units.

The coordinates of triangle 2 = (12, 20), (20, 20), (20, 16).

a = √(20 - 12)² +(20-20)² = 8

h = √(20 - 16)² +(20-20)² = 4

area = 1/2 bh

area = 1/2 (32) = 16 square units.

The coordinates of triangle 3 = (4, 4), (20, 16), (20, 4).

a = √(20 - 4)² +(16 - 4)² = 20

h = √(20 - 20)² +(16 - 4)² = 12

area = 1/2 bh

area = 1/2 (240) = 120 square units.

The coordinates of trapezoid =  (4, 4), (4, 14), (12, 20), and (20, 16)

a = √(4 - 4)² +(14 - 4)² = 10

b = √(20 - 12)² +(20-16)² = 8.94

h = √(12-4)² +(20-4)² = 17.88

4. How is the universe like rising raisin bread dough?

Answers

Answer:

one famous analogy to explain the expanding universe is imagining the universe like a loaf of raisin bread dough. As the bread rises and expands, the raisins move farther away from each other, but are still stuck in the dough.

Explanation:

Final answer:

The universe is like rising raisin bread in that it expands over time, with the distance between galaxies increasing. However, unlike the bread, the universe has no boundaries, and no center, and the galaxies themselves do not expand. This is an analogy to assist in understanding cosmic expansion.

Explanation:

The analogy between the expanding universe and the rising raisin bread is employed to explain abstract cosmological observations in a more daily-life context. Consider raisins as galaxies, and the bread dough as space. As the dough rises, it expands in a uniform manner, just as the universe does. Hence, from any raisin's (or galaxy’s) perspective, it appears as if all other raisins are moving away. Moreover, the farther a raisin is, the faster it seems to be moving away, reflecting the observation in our universe where more distant galaxies appear to recede faster from us, a phenomenon dictated by Hubble's law.

However, it’s crucial to note that this is just an analogy. Unlike raisin bread, the universe has no boundaries, no edges, and no center. Additionally, despite the universal expansion, individual galaxies are not themselves expanding; instead, they are bound together by gravity, remaining steady in size.

Lastly, this bread-raising process aligns with the concept of a 'cosmic expansion' that causes the universe to undergo a uniform change in scale over time. If this scale factor R doubles, the distance between galaxies has also doubled, highlighting another critical aspect of universal expansion.

Why was it called a world war if every country in the world was not involved?

Answers

Answer:

It's a war for control of the world. ... The Americans, on the other hand, in 1914-17 usually called it the European War. Once the United States joined the war, of course, the American media could no longer refer to it as a European war: so it became the World War. That was the first large-scale use of the term in English.

World War I was called a 'World War' because it was a conflict of vast scale, involving nations across the world, and had profound global impacts despite not every country being directly involved. Its extensive use of technology, multiple battlefronts, and significant consequences on societies and geopolitical landscapes justified its worldwide involvement characterization.

The term World War was used to describe the conflict known as World War I because it was unprecedented in its scale and scope, involving nations from nearly every continent and impacting the global demographic. It was the first conflict to be fought on multiple fronts across different lands and seas, making use of advanced industrial technology. While every country in the world might not have been directly involved, the war's effects were felt worldwide due to the involvement of colonial powers that had colonies all over the globe. The vast array of nations involved and the significant geopolitical changes that followed justified the term 'World War', despite not every country being engaged in the conflict.

The immense scale of World War I, with millions of soldiers and civilians losing their lives, the transformation of national boundaries, and the shift in hegemony from Western Europe towards the Soviet Union and the United States, all contributed to its labeling as the first world conflict.
