  1.  With no pressure over the lake and low pressure over land, the regional pressure gradient pushes cool winds towards the land.

  2.  With high pressure over the lake and low pressure over land, the regional pressure gradient pushes cool winds towards the land.

  3.  With no pressure over the lake and high pressure over land, the regional pressure gradient pushes cool winds towards the land.

  4.  With high pressure over the lake and zero pressure over land, the regional pressure gradient pushes cool winds towards the land.

Show answer
Correct Option: B
Explanation:

During summer, there occurs differential heating of the land and the water body near the land. The land mass is heated up quickly and the air over the land rises up, creating low pressure over the land. The water body takes time in getting heated up and so during the day, the water body has higher pressure due to heavy air than the land mass. Due to the pressure difference, the wind blows from the high pressure (water body) to the low pressure (land mass). These are called the sea-breeze. These winds are colder and that's why relief is felt near the lake on a hot summer day.

Hence, the correct answer is 'with high pressure over the lake and low pressure over the land, the regional pressure gradient pushes cool winds towards the land'.

Assertion : The crown fires are most destructive as they burn the tree top.

Reason : Due to crown fire the temperature of that area may rise upto 700oC.

  1. If both the assertion and the reason are true and the reason is a correct explanation of the assertion

  2. If both the assertion and reason are true but the reason is not a correct explanation of the assertion

  3. If the assertion is true but the reason is false

  4. If both the assertion and reason are false

  5. If the assertion is false but reason is true

Show answer
Correct Option: A
Explanation:

Crown files are most destructive. These destroy the canopies of trees and entire vegetational cover of that particular area. Due to this fire, the temperature, rises upto 700()oC and may adversely effect the nearly vegetation.
