NCERT Class 11 Geography — Chapter 3: Atmospheric circulation and Weather systems

With reference to Land and Sea Breezes, consider the following statements: 1. During the day, the pressure gradient is from the land to the sea. 2. During the night, the land loses heat faster than the sea. 3. Sea breeze blows from the sea to the land during the day. Which of the statements given above is/are correct?

In the context of global climatic phenomena, which of the following is the most likely impact of a strong El Niño event?

Tropical cyclones which cross 20° N latitude generally:

With reference to atmospheric pressure, consider the following statements: 1. The vertical pressure gradient force is much smaller than the horizontal pressure gradient force. 2. We do not experience strong upward winds because the vertical pressure gradient is balanced by the gravitational force. 3. Atmospheric pressure at any elevation varies from place to place, which is the primary cause of air motion. Which of the statements given above is/are correct?

Consider the following statements regarding the horizontal distribution of pressure: 1. Low-pressure systems are enclosed by one or more isobars with the lowest pressure in the center. 2. High-pressure systems are enclosed by isobars with the lowest pressure in the center. 3. Isobars are lines connecting places having equal pressure reduced to sea level. Which of the statements given above are correct?
