how did they know how our planet earth formed ?

Answers

Answer 1

Explanation:

PLANETS

about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle and a solid crust.

Surface

Like Mars and Venus, Earth has volcanoes, mountains and valleys. Earth's lithosphere, which includes the crust (both continental and oceanic) and the upper mantle, is divided into huge plates that are constantly moving. For example, the North American plate moves west over the Pacific Ocean basin, roughly at a rate equal to the growth of our fingernails. Earthquakes result when plates grind past one another, ride up over one another, collide to make mountains, or split and separate.

Earth's global ocean, which covers nearly 70 percent of the planet's surface, has an average depth of about 2.5 miles (4 kilometers) and contains 97 percent of Earth's water. Almost all of Earth's volcanoes are hidden under these oceans. Hawaii's Mauna Kea volcano is taller from base to summit than Mount Everest, but most of it is underwater. Earth's longest mountain range is also underwater, at the bottom of the Arctic and Atlantic oceans. It is four times longer than the Andes, Rockies and Himalayas combined.

Atmosphere

Near the surface, Earth has an atmosphere that consists of 78 percent nitrogen, 21 percent oxygen, and 1 percent other gases such as argon, carbon dioxide and neon. The atmosphere affects Earth's long-term climate and short-term local weather and shields us from much of the harmful radiation coming from the Sun. It also protects us from meteoroids, most of which burn up in the atmosphere, seen as meteors in the night sky, before they can strike the surface as meteorites.

Moons

Earth is the only planet that has a single moon. Our Moon is the brightest and most familiar object in the night sky. In many ways, the Moon is responsible for making Earth such a great home. It stabilizes our planet's wobble, which has made the climate less variable over thousands of years.

2)What differences are notable between people and their environment in Japan and South Korea?

3) What are some challenges related to relationships between people and their environment facing Japan and South Korea?

Thank you :)

Answers

1) Japanese and Korean languages share a similarity in certain features of their syntax and morphology while having a small number of lexical resemblances and different native scripts, although a common denominator is the presence of Chinese characters2) The military agreement between South Korea and Japan is a military intelligence-sharing pact. The reason why the governments of South Korea and Japan wanted to sign it was both South Korea and Japan are U.S. allies and have their own military alliances with the United States.3)With tensions running high, Japan and South Korea should be reminded about their convergence of interests and potential ways that they could—and should—cooperate to confront their present and future challenges.

Do the places that have monsoon rains have the highest rainfall

Answers

Answer:

the highest rainfallis plasma

Monsoons cause wet and dry seasons throughout much of the tropics. Monsoons are most often associated with the Indian Ocean. Monsoons always blow from cold to warm regions. The summer monsoon and the winter monsoon determine the climate for most of India and Southeast Asia. Overall, monthly totals average 200-300 mm over the country as a whole, with the largest values observed during the heart of the monsoon season in July and August. There was an early start to monsoon conditions during 1996, with monsoonal rains completely covering India by 30 June, 2 weeks earlier than normal.

What is one way the hydrosphere has been impacted by the movement of the continents overtime?

Answers

Answer:

Glaciers that once covered South Africa have melted and can no longer form.

Explanation:

The theory of continental drift, nowadays proven to be true, establishes that the continents are not static but in constant motion over the years, gradually changing their shape. This is proven through the existence of the supercontinent Pangea, millions of years ago.

As a consequence of continental drift, the continents that we know today have changed their position enormously. Thus, the sectors of southern Africa, which today have a hot climate due to their proximity to the equator, in ancient times were much further south, close to Antarctica at a latitude similar to that of southern Chile or Argentina today. Because it was located there, southern Africa had numerous glaciers, which with the passage of time and the movement of the continent have gradually disappeared.

A. Italy

C. Australia
D. the United States
E. New Zealand

Answers

The produce products are most likely to come from the United States, to be more specific, central USA, therefore option D

South American winters.

As per question the produce came from the united states. As America was the only source for the native American to connect to thus took the produce most likely from the neighboring states of america. They could keep their supplies intact due to the support.

Thus the answer is United states.

The winter wars of the southern American production had to be derived from the northern and central states of the country and mostly came from the exchange.As the products were in high demand in the northern countries the US was the most likely source of the items of exchange.Hence the option D is correct.

The relative ages of sedimentary rock can be determined by the sequence of layers. Index fossils allow rock layers to be correlated by age, although there are vast distances between the layers.

Answers

Answer: To date rocks geologists first give a relative age to a layer of rock at one location. Then they can give the same age to matching layers of rock at other locations. Certain fossils, called index fossils, help geologists match rock to layers.
