Part One: Exciting Introduction

There is real "acid rain" on Venus. The yellow clouds are not made of moisture, but of sulfuric acid. When it "rains", acid droplets fall from the clouds, but in a 480°C environment, the droplets evaporate before they hit the ground.

Rain is not a rare thing on earth. We often see dark clouds and rain falling from the sky. There are also clouds and storms on other planets in the solar system, but these clouds are not composed of water vapor, but other chemical substances or mixtures. Each planet has its own unique atmosphere and weather.

Read the text silently at a faster speed and require:

1. Concentrate without reading back;

3. Pay attention to key phrases when reading silently.

Maybe you run very fast. But if you race against a cheetah or an ostrich, you have no chance of winning.

When a person is running hard, the maximum speed can reach 24 kilometers per hour. This speed is far inferior to that of an ostrich - the maximum speed of an ostrich is 72 kilometers per hour. Among two-legged animals, the ostrich should be considered the world champion of running.

The animal that can run faster than an ostrich is a cheetah. The maximum speed of a cheetah can reach 110 kilometers per hour. Cheetahs are the fastest animals on land!

But the peregrine falcon dives faster, exceeding 320 kilometers per hour. This speed is two to three times the speed of a car speeding down the highway! It dives faster than any animal can run.

However, the peregrine falcon still cannot fly as fast as an airplane! At the altitude where jet aircraft fly, the speed of sound propagation is about 1050 kilometers per hour, and some high-speed jet aircraft fly at several times the speed of sound. If you shout at a person moving at supersonic speeds, he won't hear anything. Because the sound couldn't catch up with him at all.

Traveling by jet is definitely fast enough. But if you want to go to the moon, you'll need something faster. right! We need a rocket. In order to escape gravity and fly into the vast space, the speed of a rocket must be much faster than that of a jet aircraft. The rocket's maximum speed can reach 40,000 kilometers per hour, which is more than 30 times the speed of sound. After entering space, the rocket can continue to move forward even if the engine is turned off.

look! What's that thing whizzing by in front of you? Compared with its speed, the rocket seems to be stationary. That's a meteoroid! Meteoroids are smaller celestial bodies in space. The maximum speed of some meteoroids can reach 250,000 kilometers per hour, which is more than 6 times the maximum speed of rockets.
