1. Question
The Volcanoes are usually located on which of the following places
CorrectAns;- d) All of the above
Explanation;-
• The sixty percent of all active volcanoes occur at the boundaries between tectonic plates.
• The most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean, as shown in the below image where many interaction of plates takes place like Convergence and Divergence forces.
Some volcanoes, like those that form the Hawaiian Islands, occur in the interior of plates at areas called “hot spots.”

2. Question
Which type of volcanic eruptions is responsible for Deccan Trap formations in the Indian peninsular region?
Correctns;- b) Flood Basalt
Explanation:-
• The flood Basalt volcanoes contains highly fluid lava that flows for long distances.
• There can be a series of flows with some flows attaining thickness of more than 50 m.
• Some parts of the world are covered by thousands of sq. km of thick basalt lava flows Individual flows may extend for hundreds of km.
• The Deccan Traps from India, presently covering most of the Maharashtra plateau, are a much larger flood basalt province, as shown in the below image.
It is believed that initially the trap formations covered a much larger area than the present.

1. V-Shaped Valley
2. Interlocking Spurs
3. Deltas
4. Ox-Bow LakesCorrectAns;- c) Only 1,2 and 4
Explanation;-Except the Deltas all are the Erosional Features created By Rivers, Deltas are the Depositional Features of Rivers.

4. Question
Which among the following defines Pyroclastics correctly?
CorrectAns;- a) The rocks composed solely or primarily of volcanic materials
Explanation;-
• The Pyroclastic is relating to, consisting of, or denoting fragments of rock erupted by a volcano.

5. Question
What are the characteristics of shield volcanoes?
1. Mostly made up of basalt
2. Steep
3. Develop cinder cone
Select the correct codeCorrectAns;- b) 1 and 3
Explanation;-
The Shield volcanoes are mostly made up of basalt, a type of lava that is very fluid when erupted. For this reason, these volcanoes are not steep.
• They become explosive if somehow water gets into the vent otherwise, they are characterized by low-explosivity.
• Many of the largest volcanoes on Earth are shield volcanoes. The largest is Mauna Loa on the Big Island of Hawaii; all the volcanoes in the Hawaiian Islands are shield volcanoes.
• There are also shield volcanoes, for example, in Washington, Oregon, and the Galapagos Islands.
• The upcoming lava moves in the form of a fountain and throws out the cone at the top of the vent and develops into cinder cone.
THE END.
