Find a question bank for astronomy and geography to hold an event Thank you 100

There are so many things to say about this world, whether it is heaven or earth, about the vastness of the universe, the mysterious oceans, the puzzling architectural marvels, and the creatures that live in this space.

Chinese name. Astronomy Geography Essay.

Foreign name. astronomy geography composition

And this sky that will be refreshing and pleasant for anyone who sees it is also changeable, sometimes the wind roars, sometimes it is as quiet as a blue mirror, and through the atmosphere you can see the universe, the boundless universe. A friend said that he loves the sky and the universe too much, and in order to understand and study these aspects, he has also absorbed a lot of knowledge about this aspect, and he said that his dream is probably to become an astronomer and explore the universe. I finally understood why he was called "Flyer".

He is destined to be a "flyer", or perhaps a cosmic researcher more broadly. About flying and so on. Of course, it is undeniable that there are indeed too many mysteries in the universe waiting for people to explore and discover, and the scientific level of human beings is far from reaching the "high" level, otherwise, how could even the probe that flew to the depths of the universe fly for more than 20 years before flying near Neptune?

Humanity is too small for this universe. In this solar system alone, the solar system with eight planets, sixty-six moons and countless asteroids, comets and meteorites cannot be understood by human beings, let alone the edge of the universe, where is the edge of the universe? I don't know.

Earth, the third closest to the sun - that is, our home - lives "human" creatures like us, constantly exploring new matter and stars in this universe, although the sun is a big star to protect us, but if the sun's energy is swallowed up, who knows if it will become a terrible black hole? Or is it a glowing black hole in its own right? It's just that people don't detect it.

It is up to humanity to continue to explore. The fact that Pluto is not a planet has also rewritten the original nine planets of the solar system into eight planets, and the volume of Pluto is actually very small, not as big as the moon, so scientists call it a "dwarf planet". My two friends were not convinced, so he began to collect information from all walks of life and began to write about the universe about Pluto, and I don't know if writing it will make everyone acceptable.

How was the solar system formed?

Does the moon become a planet?

What is the destination of the sun? Becoming a black hole? Neutron star? White dwarf?

How do supernovae work?

Is there really a wormhole?

What is the fifth dimension of the universe?

What is the destination of the universe?

Why are there almost no fossils from 4 million to 2 million years old?

Why is the place at 30 degrees north latitude so mysterious?

When will Earth's next ice age come?

What will the Earth look like in 100 million years? What did the extrusion and drift of the plates bring to the earth at that time?

Can rats replace humans as the overlord of the planet?

First: why did the universe appear.

Second: Why are there human beings?

Thirdly: the universe was preceded by the first star composed of hydrogen. It's all hydrogen, how can planets and stars appear after that? After that, why are there stars, planets, and dust?

Third: Why do the stars and planets in the universe and some dust make up the current universe?

The last person I asked the earth where so much water came from?

I know the answer to this question.

Why do you want the hardest topic in astronomy and geography?

The sun goes out and the fastest time on earth is known.

8 minutes and 13 seconds later.

You know why.

The problem of cosmic boundaries, the problem of time and space, the problem of the existence of extraterrestrial life, etc., none of them can be studied by you for a lifetime.

What is Titius Both's Law?

Question: Knowing that the half-length longitude of the Earth's orbit is a=150000000km, and the Earth's orbit period is p=31600000s, find the mass of the Sun?

Answer: From Kepler's law: the sum of the mass of the sun m and the mass of the earth m + m = 4 2a3 gp2 = 2x1033 grams, because the mass of the sun m >> the mass of the earth m, so m = 2x1033 grams.

How do you prove that you are not living in your own or someone's dreams?

Which planet in the solar system has the most moons

Jupiter. 2.The solar system moves at a speed of about 220 kilometers per second.

3.The eight planets in the solar system all orbit in a near-circular orbit in about the same plane, orbiting the Sun in the same direction. With the exception of Venus, the other planets have the same direction of rotation and revolution.

4.At the end of the 19th century, many astronomers speculated that there were other planets besides Neptune, because the orbit of Neptune was not the same as the orbit calculated by theory. They called the star "Planet X", which means unknown planet.

5.Where is the end of the black hole, and what is it? How is it formed? How to eliminate it.

What is the most pitiful luminous celestial body on the night of August 15 in the lunar calendar? (The moon is not a luminous celestial body).

I guess you must hate you as a teacher, right? =_=!!

In fact, he just wants to promote your interest in astronomy and geography, and at the same time answer some questions that students want to know. This practice of deliberately embarrassing the teacher seems to be the common nature of many students, hehe, I also did this when I was in junior high school, at that time I was very obsessed with mathematics, and I also participated in the Olympiad, and often asked the teacher with the geometry problems I had solved (generally through special ideas to solve), and then I was happy when he couldn't think of it, and then pretended to have an epiphany in front of him. Hehe, later after going to college, I went back to see the teacher, only to know that the teacher knew that I was pretending at that time, but he didn't want to discourage my enthusiasm @ @

Don't get along with the teacher, they won't specifically target you, I am also a teacher, and the teacher wants his students to work harder in their studies and surpass themselves one day.

Having said that, I will give you a few questions, which are for you, not for your teacher, in the hope that you will enjoy astronomy. Astronomy is actually very interesting and meaningful, it has accompanied me through primary school, middle school and university, and also made me a lot of friends.

Question 1: How does an armillary sphere work?

Question 2: What year was the largest Leonid meteor shower in history? What kind of pomp? What is the reason for the occurrence?

Question 3: What is the peak cycle of the Leonid meteor shower? Why do meteor showers vary in size from year to year?

Question 4: What is a supernova? What comes after supernovae**? Have you seen it? What year did the earliest recorded supernova appear in history?

Question 5: What would happen to the Earth if a supernova** occurred closer to the solar system, and what would happen if it was 25 light-years? (The appearance of human beings today is inextricably linked to supernovae**, genetic mutations, heavy metal element production, etc., and the jewelry that people bring on the street is actually produced by supernova**.)

Finally, ask a simple question: Have you ever identified the Big Dipper and the North Star yourself? Libra, Orion, Gemini, Leo, Sagittarius, have you seen all of these yourself?

What about lunar eclipses, solar eclipses, comets? Do you know how magnitudes are distinguished? Have you ever seen a -13 magnitude green fire meteor streak across most of the sky in just a few seconds, illuminate the earth, and finally be in the distance**?

Hehe, astronomy is very far and close to us, I really hope you can also understand it, like it, and benefit from it.

PS: Geography is also a very interesting subject, especially when you use the knowledge you have learned to explain the geographical imagination that you come into contact with in daily life (especially when you explain it to MM), which is very fulfilling.

(1) The life of the sun.

Scientists guess how the results are calculated.

At each age of the Sun, the state of the Sun is characterized by its volume.

Why does the sun die?

This is a question that I asked myself, it's enough, wait a few days, and I'll get you a few after reading the encyclopedia.

You make fun of your teacher, he should go to get the Nobel if he wants to know that.

Why do aliens tell us the answer to all the natural sciences?

Why does the universe arrange its building blocks at a magnification of 100,000 times? For example:

Nucleus 10-20m

Nucleus 10-15m

Atom 10-10m

Cells 10-5 m

A few meters from the room. ...Planet 10-10 light years

Planetary systems 10-5 light years

Solar coefficient light years,

Hundreds of thousands of light-years in the Milky Way

The total star coefficient is 10 billion light years

Why is a spherical planet not a perfect positive sphere?

Why doesn't the moon fall toward the Earth, but away?

Why do aliens often emphasize that the sun 10 trillion years ago was exactly the same as it is now, when there was no Earth? ......

Hehe, I'm ...... dizzyThese problems ......It's hard to .........

How did the universe come to be, what is the current state, and what will it become in the future (the life span of the universe)?

Which planet in the solar system rotates "horizontally"?

Neptune

Hey this way, then please give me a theorem that can be used at the singularity before the universe is great, existing, or your own deduction, hey no unfounded speculation is allowed, as long as you are right, then this year's Nobel Prize is yours, and you will be called the "father of the universe" and so on.

Option B: Farmers can take care of their own rations and settle in market towns, which means that the labor force can be transferred from rural areas to market towns, that is to say, the number of people engaged in agriculture has decreased, and the number of people who can engage in industry or service in market towns has increased, which is conducive to the adjustment of industrial structure.

In ancient China, Venus was also called () A, Taibai B, Fluorite C, Zhenxing D, and Tai Sui.

Option d The Earth's rotation rotates 1° every 4 minutes, and the Earth's rotation rotates 3° in 12 minutes. At 0:12 a.m. Beijing time (120°E local time) on February 25, the meridian at 0:00 local time is 117°E. Two date dividing lines.

One is the 180° longitude international date line, and the other is the 0 o'clock local time meridian. Hence the choice D.

Two date dividing lines. One is the 180° meridian international date line, and the other is the 0 (24) hour meridian.

According to the above 0:12 a.m. Beijing time on February 25, it can be known that 120°E -0:12. The meridian at 0 is 117°. Therefore, choose D

By secondary school standards, CDs are the correct way to observe the sun (you need to be reminded that both methods are now opposed by scientists because they are still harmful to the eyes). But the question requires that you be able to observe sunspots without harming your eyes. So d is incorrect.

The negatives of color photographs are of different shades of color, and only the outline of the sun can be seen, but not the presence of sunspots.

It should be c and d can not see sunspots.

However, neither method is recommended for observing solar eclipses, and it is best to buy glasses specifically for observing solar eclipse phenomena.

American astronomers have determined the true color of the Milky Way: white as spring snow.

NASA says that binary solar planets are ubiquitous and life may exist (1) China invested $100 million to build the largest astronomical telescope.

Kunlun Station in Antarctica completed the installation of the "Antarctic Survey Telescope".

Russia said the launch failed, and the Mars probe may fall into the Pacific Ocean tonight.

Astronomical experts refute the 2012 doomsday theory: the probability of an asteroid hitting the earth is very small.

In 2012, the maximum year of the sunspot cycle will be postponed. In its just-concluded 23rd 11a cycle, there was even a month without a single sunspot. The study, published in the journal Science, is even more striking:

The sun may be about to enter a long "hibernation period".

Astronomers have discovered that not every cloud can grow into a star.
