The correct option is (d) 1, 2, 3 and 4.
Explanation
Weather and climate both describe the physical state of the atmosphere but differ in terms of time and space. Weather refers to the atmospheric conditions at a specific place over a short period, while climate refers to the aggregate or average atmospheric conditions over a long period (typically 30 years or more) over a larger area. However, the fundamental physical parameters or "elements" used to describe them are identical.
Analysis of Elements:
- 1. Temperature (Correct): Temperature measures the intensity of heat in the atmosphere. It is a primary variable for daily weather forecasts and a defining characteristic of climatic zones (e.g., Tropical or Polar climates).
- 2. Atmospheric Pressure (Correct): This is the weight of the air on a unit area. Pressure variations drive daily winds (weather) and form permanent pressure belts that define global circulation patterns (climate).
- 3. Humidity (Correct): Humidity refers to the moisture content in the air. It fluctuates hourly or daily (weather) and determines the general aridity or wetness of a region over time (climate).
- 4. Precipitation (Correct): This includes all forms of water falling from the atmosphere (rain, snow, hail). Specific rainfall events are weather, while the annual average rainfall defines the climate of a region.
Key Takeaway:
The elements of weather and climate are the same: temperature, atmospheric pressure, wind, humidity, and precipitation. The distinction lies only in the duration of observation (short-term vs. long-term).
