Show answer
Correct Option: A
Explanation:

Mount Fuji is in a Critical State and Could Be Ready To Blow. After 307 years, the massive active volcano in Japan may be due for another eruption as a result of a buildup of pressure from the 9.0-magnitude earthquake that hit the country's eastern coast in 2011.

Mount Vesuvius is the only active volcano in mainland Europe and has produced some of the continent's largest volcanic eruptions. Located on Italy's west coast, it overlooks the Bay and City of Naples and sits in the crater of the ancient Somma volcano.

  1. caldera

  2. crust

  3. crater

  4. vent

Show answer
Correct Option: A
Explanation:

Volcanic materials of various sorts are ejected through a pipe and the vent situated at the top of the pipe. The enlarged from of the volcanic vent is known a volcanic crater and caldera.

Which one of the following is an active volcano?

  1. Mt. Arata of Turkey

  2. Mt. Kulal of Kenya 

  3. Mt. Fujiyama of Japan

  4. Mt. Stromboli and Mt. Etna in Italy

Show answer
Correct Option: D
Explanation:

Stromboli is one of the most active volcanoes on Earth and has been erupting almost continuously since 1932. Because it has been active for much of the last 2,000 years and its eruptions are visible for long distances at night, it is known as the "Lighthouse of the Mediterranean". It is among the world's most visited volcanoes.

Mount Etna is Europe's highest and most active volcano. Towering above the city of Catania on the island of Sicily, it has been growing for about 500,000 years and is in the midst of a series of eruptions that began in 2001.

Which one of the following flows out from a volcano?

geography volcanoes volcanism earthquake and volcanoes development of landforms earthquakes and volcanoes types and features of earthquakes and volcanoes

  1. Water

  2. Lava

  3. Igneous rocks

  4. All of these

Show answer
Correct Option: B
Explanation:

Lava flows from the volcano. Molten rock materials are generally called magma below the earth's surface while when they come out at the earth's face they are called lava. Lava is very hot and the temperature ranges between 700 to 1200 degrees Celsius.

The funnel-shaed hollow at the top of the cone of a volcano is called ___________.

geography volcanoes volcanism earthquake and volcanoes development of landforms earthquakes and volcanoes types and features of earthquakes and volcanoes

  1. crater

  2. caldera

  3. vent

  4. magma

Show answer
Correct Option: A
Explanation:

A volcanic crater is a funnel shaped hollow at the top of the vent. It is formed as lava and gas and ash are blasted upwards from the main vent. Material falls back down to earth around the vent and slowly piles up forming a rim around it. The inside of the crater is kept clear by the force of upward moving material constantly removing any debris which falls there.
