Gravitational waves are an important confirmation of confirmation of the accuracy of Einstein's Theory of General Relativity.
What is Gravitational waves?Gravitational waves are distortions in the fabric of space and time caused by the movement of massive objects, like sound waves in air.
Also, the theory of General Relativity describes how mass warps the shape of space and how we feel that warping as gravity. It also predicts the existence of ripples traveling through spacetime, called gravitational waves.
Hence, gravitational waves are an important confirmation of confirmation of the accuracy of Einstein's Theory of General Relativity.

Levees are structures built around rivers to control and prevent flooding. In Louisiana, massive levees have been built around the Mississippi River. Prior to the levees being built, seasonal floods would deposit sediment rich in nutrients throughout the wetlands and floodplains in Louisiana. Now, the sediment is carried out to sea, and areas around the levees are rarely flooded.
What is a solution that reduces the impact of levees on the environment in Louisiana?
A
Redirect water in the continental U.S. to other rivers and coasts.
B
Increase the height of the levee's walls to prevent all possible flooding.
C
Divert, or distribute, river sediment from the state's coastal areas into wetlands.
D
Build levees that go further upstream on the Mississippi River.
A Levee is a characteristic or fake wall that blocks water from going where we do not believe it should go. It's choice C.
An answer that lessens the effect of levees on the climate in Louisiana is to Deflect, or circulate, stream dregs from the state's deep-water regions into washes.
The levees have kept sand front washes from getting the ordinary food of riverine water, supplements and residue that are introductory to deep-water swamp abidance.
Levees are constructed to alleviate flooding pitfalls; still, they don't fully exclude the threat. It's constantly conceivable that a flood tide will surpass the limit of a levee, anyhow of how well the construction is fabricated.

An economic consequence of the map given is that people in North Korea are economically backward compared to South Korea.
Another contemporary border conflict was that of North and South Vietnam which was resolved by the Vietnam War.
What does the map say about the Korean War?The Korean War happened because the United States and the Soviet Union divided it along political lines with the North being communist and the South being democratic.
Centripetal forces are those that pull people together which in this case, is the shared ethnicity of being Korean. Centrifugal forces pull people apart so in this case refers to the different political ideologies of both Koreas.
When a ceasefire was called, the political boundary became the military demarcation line. With the North closed off, they became economically backward while the South prospered.

Answer:

Explanation:
the South Pole is 90 degrees South too
0° of latitude is found at the equator and 90° of latitude is found at the north pole.
What is the Equator?A ring that circles a planet or other celestial body's axis is said to be its equator. The northern and southern hemispheres are separated by the Equator. The South Pole is 90 degrees S latitude, and the North Pole is 90 degrees N latitude.
With a latitude of 0 degrees, it is midway between the north and south poles. All year long, the climate is warm in towns and cities near the equator. The reason for this is that the sun is nearly always straight overhead.
The Equator is the place on Earth where it is the largest. The Equator heats up more quickly than the poles because sunlight strikes a smaller surface area there. There are few seasonal temperature variations close to the equator.

Are summers in the northern hemisphere getting longer?
Answer:
Yes
Explanation:
As the Earth circles the Sun during the year, half of the Earth get more or less sunlight than the other half of the Earth. In the summer months, the northern half of the Earth, where we live, tilts towards the Sun. This means we get more sunlight, making the days longer.
The summers in the Northern Hemisphere getting longer, due to the change in the climate.
What is climate change?Long-term changes in climate and weather systems are referred to as climate change.
Although these changes are natural, human operations have been the primary driver of temperature change since the 1800s, owing to the combustion of fossil fuels which releases heat-trapping gases.
During the year, as the Earth circles the Sun, half of the Earth receives more or less sunlight than the other half. The northern half of the Earth, where we dwell, tilts towards the Sun during the summer months. This means we get more sunlight, which lengthens the days.
Therefore, the summers in the Northern Hemisphere getting longer.

Tropical plant fossils in Antarctica indicate it used to be closer to the equator.
The plates are moving about 2.5 cms per year.
All of the rivers are now frozen.
Fossils were not found on any continent, proving there was no life.
Answer:
Explanation:
As these fossils suggest, Antarctica hasn’t always been as cold as it is now. Before Captain Scott and his team perished during their return journey from the South Pole in 1912, they had collected a number of important fossils from near the Beardmore Glacier in the Transantarctic Mountains. When this collection was retrieved and analysed, it was found to contain fossils of an ancient ‘seed-fern’ tree (Glossopteris). Not only did this prove that the continent must have been much warmer in the past to support such vegetation, but the similarity with Glossopteris fossils found in South America, South Africa, and Australia gave strong support to the emerging idea, championed by Alfred Wegener, that the continents were once joined and have since moved apart – the theory of ‘continental drift’.During the 1960s, the mechanisms behind continental drift finally became understood and our modern theory of plate tectonics was born. As with other continents, sea floor spreadingin some places and subduction in others has caused Antarctica’s position to change over geological time; and hence Antarctica hasn’t always been located over the South Pole. Indeed in the distant geological past, the pattern and configuration of tectonic plates has been very different from today. For example, about 450 million years ago the crust that makes up England was in the Southern Hemisphere while crust making up Antarctica straddled the equator!Some 200 million years ago, Antarctic continental crust was joined with South American, African, Indian, and Australian continental crust making up a large southern land mass known as Gondwana (the southern part of the supercontinent called Pangea). After this time, Gondwana slowly split apart to create Antarctica as a separate continent, and Antarctica has gradually moved away from the other southern continents towards its present polar position.

Which statement best descibes the overall message conveyed in this political cartoon? Climate change is something the Earth can predict. The future effects of global climate change could be devastating if we do not address it. Climate change will affect our weather patterns in the future. The future effects of global climate change will not be seen for hundreds of years.
The basic idea presented in this political cartoon is that if we do not handle global climate change, the consequences could be disastrous.
What happens if we don't address climate change?Climate Change and Its Consequences are more frequent wildfires, prolonged drought periods in some locations, and an increase in the number, duration, and severity of tropical storms are all possible future implications of global climate change.
If we do nothing, heat waves will become more common and severe over the planet, harming hundreds of millions—if not billions—of people.
Therefore, option (b) or (ii) is the correct answer.
