Class 6 English Anak Krakatoa
Q: What is a volcano?
A volcano is a crack or opening in the earth’s crust through which hot molten rock can erupt.
Q: What happens during a volcanic eruption?
Thick clouds of smoke rise from the opening, burning chunks of rock and red hot lava are thrown out, and hot mud and ash are also ejected.
Q: How are volcanoes classified?
Volcanoes are classified as active, dormant, or extinct based on their level of activity.
Q: What are extinct volcanoes?
Extinct volcanoes are those that have not erupted in recorded history and are unlikely to erupt again.
Q: What happened during Krakatoa’s worst eruption in 1883?
A loud boom could be heard 3500 km away, the island collapsed, and 165 villages and towns were destroyed by giant waves or tsunamis.
Q: What was the result of the 1883 Krakatoa eruption?
The island was destroyed in two-thirds, and a huge underwater volcanic crater was formed.
Q: Has there been any volcanic activity on Krakatoa since the 1883 eruption?
There was another eruption in 1927, and a new island volcano broke the water a few days later.
Q: How did Anak Krakatoa, the new island, form?
Anak Krakatoa formed from the volcanic material that was not taken away by the waves after the old island of Krakatoa collapsed.
Q: Is Anak Krakatoa an active volcano?
Anak Krakatoa is still an active volcano, and eruptions have occurred since 1994.
Q: How has Anak Krakatoa grown over time?
Since 1950, Anak Krakatoa has grown an average of five inches per week.
Q: What happened to the surrounding islands and coasts after the 1883 Krakatoa eruption?
They were covered with hot ash, and there was no sign of life. It is believed, however, that seeds of plants and animals were brought to the island via wind, sea, and birds, and that small land animals such as ants, termites, rats, and lizards travelled on plants floating in the sea.
Q: What is the significance of the island of Rakata and Anak Krakatoa for scientists?
In the absence of human interference, scientists can observe how living things develop in an area and how wildlife can grow and thrive naturally. Due to the absence of human interference, Krakatoa’s eruption also increased wildlife on Java’s western coast.
