Question 1 of 5
1. Question
What are the characteristics of shield volcanoes?
- Mostly made up of basalt
- Steep
- Develop cinder cone
Select the correct code
Correct
Answer – B
- 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 characterised by low-explosivity.
- 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.

Question 2 of 5
2. Question
Caldera volcanic eruptions are characterised by
- No significant landform formation
- Magma chamber in close vicinity
Which of the above is/are correct
Correct
Answer – b
- Calderas are the most explosive of the earth’s volcanoes.
- They are usually so explosive that when they erupt they tend to collapse on themselves rather than building any tall structure. The collapsed depressions are called calderas.
- Their explosiveness indicates that the magma chamber supplying the lava is not only huge but is also in close vicinity.

Question 3 of 5
3. Question
Find the characteristics of composite volcanoes
- Violent eruption
- Cool lava
Select the correct code
Correct
Answer – C
- Composite Volcanoes are characterised by eruptions of cooler and more viscous lavas than basalt. These volcanoes often result in explosive eruptions.
- Along with lava, large quantities of pyroclastic material and ashes find their way to the ground. This material accumulates in the vicinity of the vent openings leading to formation of layers, and this makes the mounts appear as composite volcanoes.

Question 5 of 5
5. Question
Consider the statements below about Mid oceanic ridges
- Around 70000 km long in the ocean
- Frequent eruptions
- Stretch through all oceans
Which of the above is/are correct

Answer – D
- Mid-Ocean Ridge Volcanoes occur in the oceanic areas. There is a system of mid-ocean ridges more than 70,000 km long that stretches through all the ocean basins.
- The central portion of this ridge experiences frequent eruptions.
