• Question 1 of 5 1. Question The vertical pressure gradient force is much larger than that of the horizontal pressure gradient. But we do not experience strong upward winds, because of (a) Strong Planetary winds (b) Strong Coriolis force (c) Strong frictional force in lower atmosphere (d) Strong Gravitational force Correct Solution: D The vertical pressure gradient force is much larger than that of the horizontal pressure gradient. But, it is generally balanced by a nearly equal but opposite gravitational force. Hence, we do not experience strong upward winds. Due to gravity the air at the surface is denser and hence has higher pressure. Incorrect Solution: D The vertical pressure gradient force is much larger than that of the horizontal pressure gradient. But, it is generally balanced by a nearly equal but opposite gravitational force. Hence, we do not experience strong upward winds. Due to gravity the air at the surface is denser and hence has higher pressure.
#### 1. Question
The vertical pressure gradient force is much larger than that of the horizontal pressure gradient. But we do not experience strong upward winds, because of
• (a) Strong Planetary winds
• (b) Strong Coriolis force
• (c) Strong frictional force in lower atmosphere
• (d) Strong Gravitational force
Solution: D
The vertical pressure gradient force is much larger than that of the horizontal pressure gradient. But, it is generally balanced by a nearly equal but opposite gravitational force. Hence, we do not experience strong upward winds. Due to gravity the air at the surface is denser and hence has higher pressure.

• Question 2 of 5 2. Question Consider the following statements regarding the vertical distribution of ocean temperature. The heat is transmitted from the surface of the ocean to the lower sections of the oceans through the process of convection. A thermocline is the transition layer between warmer mixed water at the ocean’s surface and cooler deep water below. About 10 percent of the total volume of water is found below the thermocline in the deep ocean. How many of the above statements is/are correct? (a) Only one (b) Only two (c) All three (d) None Correct Solution: B Statement 3 is incorrect. The temperature-depth profile for the ocean water shows how the temperature decreases with the increasing depth. The profile shows a boundary region between the surface waters of the ocean and the deeper layers. The boundary usually begins around 100 – 400 m below the sea surface and extends several hundreds of metres downward. This boundary region, from where there is a rapid decrease of temperature, is called the thermocline. About 90 per cent of the total volume of water is found below the thermocline in the deep ocean. In this zone, temperatures approach 0° C. It is a well-known fact that the maximum temperature of the oceans is always at their surfaces because they directly receive the heat from the sun and the heat is transmitted to the lower sections of the oceans through the process of convection.

• Question 3 of 5 3. Question The speed of tsunami waves in Ocean largely depends on a) Density of water b) Distance from mid-oceanic ridges c) Ocean depth d) Distance from the source of the wave Correct Solution: C Tsunamis are giant waves caused by earthquakes or volcanic eruptions under the sea. Out in the depths of the ocean, tsunami waves do not dramatically increase in height. But as the waves travel inland, they build up to higher and higher heights as the depth of the ocean decreases. It depends on Ocean depth rather than the distance from the source of the wave. Tsunami waves may travel as fast as jet planes over deep waters, only slowing down when reaching shallow waters.

• Question 5 of 5 5. Question Consider the following statements. Wet-bulb temperature combines heat and humidity to indicate how much evaporation can be absorbed into the air. The wet bulb temperature is usually higher than the dry bulb temperature. At wet-bulb temperatures above 35 degrees Celsius, it becomes difficult to reduce body temperature via sweating. How many of the above statements is/are incorrect? (a) Only one b) Only two c) All three d) None Correct Solution: A Statement 2 is incorrect. The wet bulb temperature is usually lower than the dry bulb temperature, and the difference between the two increases dramatically as the air becomes dry. The most worrying weather measurement is not the heat typically reported in forecasts but the wet-bulb temperature, which combines heat and humidity to indicate how much evaporation can be absorbed into the air. At wet-bulb temperatures above 35 degrees Celsius, we become unable to reduce our temperature via sweating and will suffer potentially fatal heatstroke after only a few hours, even with shade and water.
