摘要

Have you ever heard of Iceland?Iceland is a country,one-tenth of which is covered with ice.However,it is said that Iceland is the land of heat Smoking volcanoes(火山),white steam,and hot springs are amazing features that people can see there.It has taken millions of years for volcanoes and lava flows(熔岩流)to build Iceland.When hiking through one ofleland's many ancient lava fields,you may notice something strange.White steam rises from each vent(排放口)and shoots many metres into the air.Iceland is covered with vents which steam can pass out of.The steam comes from naturally heated rocks and hot water below the Earth's surface.
