Question 1 of 5
1. Question
Which of the following pairs are correctly matched?
Mountain Place
- Mount Kilimanjaro Africa
- Mount Aconcagua South America
- Mount Sinabung Indonesia
- Mount Paektu Philippines
Select the correct answer code:
Correct
Solution: b)
Indonesia’s Mount Sinabung volcano erupted recently. The volcano became active in 2010, erupting after nearly 400 years of inactivity. Indonesia is home to many active volcanoes, due to its position on the “Ring of Fire”, or the Circum-Pacific Belt, which is an area along the Pacific Ocean characterised by active volcanoes and frequent earthquakes. The Ring of Fire is home to about 75 per cent of the world’s volcanoes and about 90 per cent of its earthquakes.
Mount Kilimanjaro is a dormant volcano in Tanzania.
It is the highest mountain in Africa.
Mount Paektu or Changbai (in Chinese) is a volcanic mountain that last erupted over 1,000 years ago.
Situated at the border between Democratic People’s Republic of Korea and China.
At a height of about 9,000 feet, it is also the highest peak in the Korean peninsula.
Mt. Aconcagua
It is the highest peak of the Andes Mountains in Argentina, South America. The mountain is one of the so-called Seven Summits of the seven continents.

Question 2 of 5
2. Question
Consider the following statements.
- A volcanic eruption takes place when magma formed when the earth’s mantle melts, rises to the surface.
- The explosivity of the volcano depends on the composition of the magma.
- When the magma is runny and thin it usually leads to a violent explosion.
Which of the above statements is/are correct?
Correct
Solution: c)
A volcano can be active, dormant or extinct. An eruption takes place when magma (a thick flowing substance), formed when the earth’s mantle melts, rises to the surface. Because magma is lighter than solid rock, it is able to rise through vents and fissures on the surface of the earth. After it has erupted, it is called lava.
Not all volcanic eruptions are explosive, since explosivity depends on the composition of the magma. When the magma is runny and thin, gases can easily escape it, in which case, the magma will flow out towards the surface. On the other hand, if the magma is thick and dense, gases cannot escape it, which builds up pressure inside until the gases escape in a violent explosion.
The most common cause of death from a volcano is suffocation, making people with respiratory conditions such as asthma and other chronic lung diseases especially susceptible.
Volcanic eruptions can result in additional threats to health such as floods, mudslides, power outages, drinking water contamination and wildfires.
Lava flows, however, rarely kill people, since they move slowly, giving enough time to escape.

Question 5 of 5
5. Question
Consider the following statements regarding Aurora or Northern lights.
- Auroras are the glowing lights at high latitude.
- Auroras can be normally observed in stratosphere.
- Change in the atmospheric temperature cause Auroras.
Which of the above statement is/are correct?
Correct
Solution: b)
An aurora, sometimes referred to as polar lights, northern lights (aurora borealis) or southern lights (aurora australis), is a natural light display in the Earth’s sky, predominantly seen in the high latitude regions (around the Arctic and Antarctic).
Auroras are produced when the magnetosphere is sufficiently disturbed by the solar wind. It usually occur in upper atmosphere (thermosphere/exosphere) due to Earth’s magnetic field.
