It shows a volcano erupting.

11 volcanic eruption Boiling rock erupts from the crater;
Ash cloud/volcanic ash Crater volcanic eruption Lava Boiling rock erupts from the crater; the lava flows slowly down the mountain. Magma chamber

12 More about the volcano 1. How is a volcano formed?
The rocks under the earth become hotter and hotter and erupt from the mountain.

13 Where is it most possible for a
volcano to erupt? Near the oceans.

14 3. What types of volcanoes do you know?
An extinct volcano A dormant volcano Haleakala Crater, the largest dormant volcano(休眠火山) in the world Maui, Hawaii An active volcano

15 The Kilauea volcano Let’s learn something about a famous volcano.

16 More information about Mount Kilauea
The Kilauea volcano More information about Mount Kilauea Mount Kilauea is one of the most active volcanoes on Earth. “Kilauea” means “spewing(喷涌)” or “much spreading”, apparently in reference to the lava flows that it erupts. Mount Kilauea in Hawaii has erupted 62 times in 245 years. The current eruption began in January 1983 and has been going on ever since.

17 夏威夷的基拉韦厄火山于1983年的1月开始喷发,在喷发时出现了一个壮观、弓状结构的熔岩喷涌。

18 1983年1月7日,地质学家准备在基拉韦厄火山东部断裂带还在背景里喷发的活动排放口附近收集熔岩的样本。

19 2010年5月,夏威夷基拉韦厄火山的熔岩从卡拉帕纳流进了海洋。

20 夏威夷大岛,火山研究人员正从熔岩中采样进行研究,以帮助阻止这个岛上的小镇被岩浆吞噬。据悉,这些熔岩的最高温度可达1200摄氏度,如果一名没穿防护服的人不幸被飞溅的熔岩击中,他将会瞬间化为灰烬。
