极地气候带
了解极地地区属于极地气候带——地球五大主要气候带（热带、干旱带、温带、大陆性气候带、极地气候带）之一——其特征是即使在夏季气温也很少超过10°C，降水稀少（极地沙漠的降水量比撒哈拉沙漠还少），且风力强劲；知道纬度是决定气候带的关键因素，极地地区位于北纬或南纬60°以上。
Understand that polar regions belong to the polar climate zone — one of Earth's five main climate zones (tropical, arid, temperate, continental, polar) — characterised by temperatures rarely above 10°C even in summer, low precipitation (polar deserts receive less rain than the Sahara), and strong winds; know that latitude is the key factor determining climate zones, with polar regions above 60°N/S
学习证据 / Evidence
- 说出地球五大主要气候带，并正确地将极地地区归入其中。
- 说明极地地区大致位于纬度60°以上，并解释远离赤道是极地寒冷的主要原因。
- 描述极地气候特征：夏季气温很少超过10°C，降水量极低，风力强劲。
- Name the five main climate zones and place polar regions correctly within them
- State that polar regions are above approximately 60° latitude and explain that distance from the Equator is the main reason they are cold
- Describe polar climate characteristics: rarely above 10°C in summer, very low precipitation, strong winds
评估问题 / Assessment
{{name}}能否解释极地气候带在地球五大气候带中的位置，以及极地为何如此寒冷——并将其与高纬度、远离赤道的位置联系起来？
Can {{name}} explain where the polar climate zone fits among Earth's five climate zones, and why the poles are so cold — linking it to their position at high latitudes far from the Equator?
