白天的天空为什么是蓝的?
Why is the daytime sky blue?
阳光里蓝光照得最远,被空气散开布满天空,所以我们看到蓝天。
Blue light in sunlight spreads farthest through the air and fills the sky, so we see a blue sky.

傍晚天空为什么变成橘色?
Why does the sky turn orange at sunset?
傍晚太阳斜着照,蓝光被挡住,剩下红橙光铺满天空,就变成橘色。
At sunset the Sun is low, blue light is blocked, and the leftover red and orange light paints the sky.

沙漠为什么那么干?
Why are deserts so dry?
沙漠地方雨下得很少,太阳又毒,水分很快被晒干,所以特别干。
Deserts get very little rain and strong sun, so water dries up fast and the land stays very dry.

极地为什么有极昼?
Why do polar regions have the midnight sun?
地球自转轴是歪的,极地半年对着太阳、半年背着,于是出现极昼和极夜。夏天太阳不落山,冬天几乎不见太阳。
Earth's axis is tilted, so the poles face the Sun for half the year and away for the other half, creating midnight sun and polar night. In summer the Sun never sets; in winter it barely rises.

沙漠为什么白天热夜里冷?
Why do deserts swing from hot days to cold nights?
沙漠空气干、云少,白天太阳直晒升温快,夜里热量很快散到天上,所以昼夜温差极大。有些沙漠白天烫脚、半夜结霜。
Deserts have dry air and few clouds, so days heat up fast under direct sun while nights lose heat quickly to the sky, giving huge day-night swings. Some deserts are scorching by day and frosty at midnight.

为什么不同地方气候不同?
Why do different places have different climates?
一个地方的气候由纬度、山海位置和离海远近决定,阳光多少和风向都不同。靠近赤道更热,靠海更湿润,所以各地气候不一样。
A place's climate is shaped by its latitude, its mountains and oceans, and its distance from the sea, which change how much sun and wind it gets. The equator is hotter and coasts are wetter, so climates vary.

天空为什么有时灰蒙蒙?
Why is the sky sometimes gray?
阴天时厚云把阳光挡住并散射成白光,加上空气中的灰尘和水珠,天空就显得灰白。城市污染也会让天更灰。
On overcast days thick clouds block sunlight and scatter it into white while dust and water drops fill the air, making the sky look gray. City pollution can make it grayer still.

星星白天去哪儿了?
Why do stars disappear in the daytime?
白天太阳光把整片天空照亮,星星的光太弱就被盖住了,所以我们白天看不见星。其实星星一直都在。
Daytime sunlight brightens the whole sky and drowns out the faint starlight, so we cannot see stars. The stars are actually still there.
