为什么爬山时越往上越冷？
Why does it get colder as you climb a mountain?
靠近地面的空气先被太阳晒热。热空气往上升的时候会慢慢膨胀,温度一点点降下来,升到山顶时已经凉快了,所以越高越冷。
The sun warms the air near the ground. As that warm air rises it spreads out and cools a little all the way up, so the mountain top is much colder than the base.

极光为什么只在地球两极附近出现？
Why does the aurora appear only near the Earth's poles?
太阳带电粒子被地球磁场引到南北两极，撞击高空大气发出彩光，所以在极区最容易看到极光。
The solar wind's charged particles are funneled by Earth's magnetic field to the poles, hitting the upper atmosphere to glow—hence auroras near the poles.

彩虹为什么总是弯弯的半圆？
Why is a rainbow always a curved arc?
阳光在水滴里折射、反射后分散成七色，而每个角度相同的光点连起来恰好是个圆，我们常只看见地平线以上的半边。
Sunlight refracts and reflects in droplets into colors; points at the same angle form a circle, and we usually see only the upper half above the horizon.
