Question

Which factor cause variation in the atmospheric pressure?

• A. altitude
• B. Temperature
• C. nearness to sea
• D. latitude

Answer 1

Answer:

B. Temperature

Atmospheric temperature

• Solar energy is not uniformly distributed on the surface of the earth.

• Atmospheric temperature is not uniform everywhere.

• The heat received on the surface of the earth is in accordance with the latitude of the place.

• Equatorial regions have high temperature than other regions.

• The factors such as altitude, nearness to sea, etc. Also cause local variations in the temperature conditions. The atmospheric temperature decreases gradually with the increase in altitude. The temperature of the coastal regions is regulated by the winds blowing from sea to land during day time and vice versa during night.

• Variations in the atmospheric temperature contribute to weather factors such as pressure changes, wind, humidity, condensation, precipitation etc.

• Atmospheric temperature is measured using the instrument called thermometer.
