• Question 3 of 5 3. Question Consider the following statements. It is more likely for a river to change course in the alluvial plains of North India. The northward movement of the Indian Tectonic Plate is the reason behind the rising Himalayas. Ganga river is the only river in India which has not changed its course in the last 200 years. Which of the above statements are correct? (a) 1 and 2 only (b) 1 and 3 only (c) 2 and 3 only (d) 1, 2 and 3 Correct Solution: A Changes in a river’s course in the northern part of the country is not unusual. One of the reasons is believed to be the movement of the Indian Tectonic Plate. The Plate has been moving northward. That is the reason the Himalayas are rising. One reason for the course of the Yamuna moving eastwards too is believed to be this. Also, it is more likely for a river to change course in the alluvial plains of North India. “Alluvial terrain is soft and more amenable to changing river courses. If we look at the course of the Ganga between 1786 and now, there are places where it has changed its course by 34 km. In Badaun (UP) the river has moved 10 km from where it used to be.

• Question 4 of 5 4. Question Consider the following statements. The Earth’s geological time scale is based on events, such as the evolution and extinction of different living beings and processes that have occurred. Anthropocene epochis a proposed geological epoch that began when the human impact started to radically alter the Earth’s ecosystem and geology. Eons, epochs, eras, periods, and ages are the different categories of Earth’s geological time scale. Which of the above statements are correct? (a) 1 and 2 only (b) 1 and 3 only (c) 2 and 3 only (d) 1, 2 and 3 Correct Solution: D The Earth’s geological time scale is a fundamental tool used by geologists, palaeontologists and other scientists to study the planet’s past. It is a system that divides the history of the Earth into discrete intervals of time, based on events, such as the evolution and extinction of different living beings and processes that have occurred. It is divided into five broad categories: eons, epochs, eras, periods, and ages. As of now, at least officially, we’re in the Phanerozoic eon, Cenozoic era, Quaternary period, Holocene epoch and the Meghalayan age.

• Question 5 of 5 5. Question Consider the following statements regarding heat dome. A heat dome occurs when an area of low-pressure traps warm air over a region. Heat domes generally stay for a few days but sometimes they can extend up to weeks, which might cause heat waves. The heat dome’s formation is related to the behaviour of the jet stream. How many of the above statements are incorrect? (a) Only one (b) Only two (c) All three (d) None Correct Solution: A Statement 1 is incorrect. A heat dome occurs when an area of high-pressure traps warm air over a region, just like a lid on a pot, for an extended period of time. The longer that air remains trapped, the more the sun works to heat the air, producing warmer conditions with every passing day. Heat domes generally stay for a few days but sometimes they can extend up to weeks, which might cause deadly heat waves. Scientists suggest that any region of high pressure, whether a heat dome or not, forces air to sink and once it reaches the ground, it gets compressed and becomes even warmer. Moreover, when air sinks, it gets drier and further raises the temperature of the area. The heat dome’s formation is related to the behaviour of the jet stream — an area of fast-moving air high in the atmosphere. The jet stream is believed to have a wave-like pattern that keeps moving from north to south and then north again. When these waves get bigger and elongated, they move slowly and sometimes can become stationary. This is when a high-pressure system gets stuck and leads to the occurrence of a heat dome. Although heat domes are likely to have always existed, researchers say that climate change may be making them more intense and longer. They suggest with the rising temperatures, it is expected that the jet stream will become more wavy and will have larger deviations, causing more frequent extreme heat events.
