Polar Climate Zone

CONCEPTUAL

Science›Polar Regions|Ages 9—11|ID: mt_GbZFuGDFsa

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

Mastery Evidence

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

Assessment Prompt

“Can [child] 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?”
