The impact of the moon on the earth s environment is listed, and some of the content is analyzed in

The topography of the Moon consists mainly of craters.

Moon sea, moon land and mountains, moon surface radiation pattern, moon valley, etc.

1. Crater: The name is Galileo.

up. It is a distinctive feature of the lunar surface and covers almost the entire lunar surface. The largest crater is the Bailey crater near Antarctica, with a diameter of 295 kilometers, larger than Hainan Island.

It's a little bigger. 2. Moon Sea: The dark part of the moon that humans on Earth see with the naked eye is actually a vast plain on the moon.

The Moon Sea is generally low, similar to the basins on Earth, with the Moon Sea 1-2 km below the average level of the Moon, and the lowest sea, such as the southeastern part of the Rain Sea, is even 6,000 meters lower than the surrounding areas.

3. Lunar land and mountain ranges: The area above the lunar sea on the lunar surface is called lunar land, which is generally 2-3 kilometers higher than the lunar sea level, and it seems to be relatively bright because of its high albetry. On the front side of the Moon, the area of the lunar land is roughly equal to the lunar sea but on the far side of the Moon.

The area of the Moon Land is much larger than that of the Moon Sea. On the Moon, in addition to the numerous craters that intersect with dogs' teeth, there are also some mountains similar to those on Earth.

4. Radiant pattern on the lunar surface: Another major feature on the lunar surface is that some "younger" craters often have beautiful "radial lines", which is a bright belt that extends in all directions with the crater as the radiant point, and it passes through the mountain system, the moon sea and the crater in an almost straight direction.

5. Moon Valley (Moon Gap): There are large black cracks on the surface of the moon that seem to be curved, that is, Moon Valley, some of them stretch for hundreds to thousands of kilometers, and the width varies from thousands of meters to tens of kilometers.

In the Earth-Moon system, what does the Moon have no effect on the Earth? （）a.Blocks the damage of solar radiation to the earth.

b.It has withstood the impact of some small celestial bodies on the Earth.

c.Causes tidal changes in the Earth's oceans.

d.The gravitational pull of the Moon slows down the Earth's rotation.

e.Cause the instability of the Earth's autobiographical posture code this modulus width line.

Correct Answer: ae

is wrong. There are mountains, basins, but no lakes on the moon.

There is no atmosphere, no water, and a dry world on the Moon. There are many mountains and highlands on the moon, and it is the bright part of the moon that is seen from the earth. There are also many dark areas of different sizes on the Moon, which are flat, low-lying areas on the Moon and are named after "seas", such as:

The Sea of Rain, the Sea of Tranquility, the Sea of Wine, the Sea of Abundance, the Ocean of Storms, etc., and the smaller ones are called basins. But there is no water in it, but these places have a weaker ability to reflect the sun's light, so they look darker.

The far side of the Moon.

The biggest feature of the lunar landform is the distribution of many large and small craters. Craters are mostly circular, with single ones, several stacked on top of each other, and large rings with small rings. The diameter of craters is less than a kilometer, and some are several hundred kilometers in diameter.

The topography of the moon mainly includes craters, lunar seas, lunar lands and mountains, lunar radiant patterns, moon valleys, etc., which are described in detail below.

The name crater was given by Galileo. It is a distinctive feature of the lunar surface and covers almost the entire lunar surface. The largest crater is the Bailey crater near Antarctica, with a diameter of 295 kilometers, which is slightly larger than Hainan Island.

A small crater may even be a pothole of a few tens of centimeters. There are about 33,000 of them with a diameter of not less than 1,000 meters. 7-10% of the lunar surface area.

The effects of the Moon on the Earth are manifold, and here are some of the main ones:

1.Gravitational and tidal forces: The gravitational pull of the Moon creates a gravitational and tidal force on the Earth's oceans. The tidal force causes the periodic rise and fall of the water level in the ocean caused by the tidal force. This has important implications for areas such as marine ecosystems, fisheries and shipping.

2.Precession movement: The gravitational pull of the Moon on the Earth also causes subtle changes in the Earth's axis of rotation, resulting in precession movement. Precession sports cause periodic changes in the seasons on the earth, affecting climate and agriculture, among other things.

3.Stable orbit: The presence of the Moon plays a role in the stability of the Earth's orbit. The Moon's gravitational pull adjusts the Earth's orbit, maintaining a stable orbit around the Sun. Without the Moon, the Earth's orbit would probably be more unstable.

4.Solar wind resistance screen: The moon can reduce the impact of solar wind on the earth at a certain degree of austerity. The Moon has a thin layer of gas, which can block some of the charged particles from the Sun, reducing the direct impact of the solar wind and protecting the Earth.

5.Academic research and exploration: The Moon is an important target for scientific research and space exploration. Through the exploration and study of the Moon, we can understand the formation and evolution process of the Moon, and can also provide important clues to the origin and evolution of the Earth.

6.Culture and the Human Imagination: The Moon has played an important role in human history and culture. The observation and exploration of the Moon has sparked curiosity and imagination, influencing literature, art, and religion.

These are some of the main effects of the Moon on the Earth. Through the study and observation of the Moon, people can better understand the correlation between the Earth and the solar system, and promote the development of science and the progress of human civilization.
