• Question 1 of 5 1. Question Consider the following statements regarding Sinkholes. Sinkholes are depressions formed in the ground when layers of the Earth’s surface start collapsing into caverns. They are formed in areas of “karst” terrains, where the rock below the surface of the Earth can be easily dissolved by groundwater. They are formed due to natural processes or human activity. Which of the above statements is/are correct? a) 1, 2 b) 1, 3 c) 2, 3 d) 1, 2, 3 Correct Solution: d) Sinkholes are depressions formed in the ground when layers of the Earth’s surface start collapsing into caverns. They can occur suddenly and without warning, because the land under the surface of the Earth can stay intact for a period of time until the spaces get too big. Sinkholes can be formed due to natural processes or human activity. Typically, sinkholes form in areas of “karst” terrains, where the rock below the surface of the Earth can be easily dissolved by groundwater. Essentially, this means that when rainwater seeps into the ground, the rock below the surface of the Earth starts dissolving, leading to the creation of spaces. This process is a slow and gradual one and can sometimes take hundreds or thousands of years.

• Question 4 of 5 4. Question Consider the following statements. Geothermal gradient is the rate of temperature change with respect to increasing depth in Earth’s interior. Magma is lighter than solid rock and hence it rises. Usually Magma that is thick and sticky leads to explosive volcanic eruptions, compared to magmathat has low viscosity. Which of the above statements is/are correct? a) 1, 2 b) 1, 3 c) 2, 3 d) 1, 2, 3 Correct Solution: d) The geothermal gradient, the amount that the Earth’s temperature increases with depth, indicates heat flowing from the Earth’s warm interior to its surface. At a certain depth, the heat is such that it melts rocks and creates what geologists call ‘magma’. Magma is lighter than solid rock and hence it rises, collecting in magma chambers. Chambers which have the potential to cause volcanic eruptions are found at a relatively shallow depth. The magma that surfaces on the Earth’s crust is referred to as lava. Why are some volcanic eruptions explosive and some not? In simple terms, runny magma makes for less explosive volcanic eruptions that typically are less dangerous. Since the magma is runny, gasses are able to escape, leading to a steady but relatively gentle flow of lava out of the mouth of the volcano. The eruption at Mauna Loa is of this kind. Since the lava flows out at a slow pace, people typically have enough time to move out of the way. If magma is thick and sticky, it makes it harder for gasses to escape on a consistent basis. This leads to a build-up of pressure until a breaking point is reached. At this time, the gasses escape violently, all at once, causing an explosion. Mount Vesuvius, which obliterated the city of Pompeii, is an example of an explosive volcano. The Volcanic Explosivity Index (VEI) is a scale used to measure the explosivity of a volcano. It has a range of 1 to 8 with a higher VEI indicating more explosivity.

• Question 5 of 5 5. Question Consider the following statements regarding Cyclones. A cyclone is a low-pressure system that forms over warm waters. It is a system of high-speed winds blowing clockwise in the Northern Hemisphere and counter-clockwise in the Southern Hemisphere. Tropical cyclones in the formative stages of their development are very calm and does not cause any threat to life and property. Which of the above statements is/are correct? a) 1 only b) 1, 2 c) 1, 3 d) 1, 2, 3 Correct Solution: a) A cyclone is a low pressure system that forms over warm waters. Essentially, it is a system of high speed winds rotating around a low-pressure area, with the winds blowing counter clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. According to the World Meteorological Organization, “Tropical cyclones are one of the biggest threats to life and property even in the formative stages of their development. They include a number of different hazards that can individually cause significant impacts on life and property, such as storm surge, flooding, extreme winds, tornadoes and lighting.
