Question

notes on chapter 6 elements of weather and climate

​

Answer 1

Explanation:

The day-to-day conditions of the atmosphere at a location concerning elements such as humidity, temperature, wind intensity, rainfall, etc. are called the weather at that location.

Complete step by step solution:

Elements of Weather and Climate:

1. Humidity –

Humidity is another weather element that cannot be seen but can be felt.

It not only plays a big part in weather formation but also directly influence our physical comfort levels.

2. Temperature –

Temperature is a measure of the amount of kinetic energy contained in the air that expresses itself externally by the perception of heat or cold.

Wind speed –

Airflow (wind) is one of the major guiding forces of the atmosphere.

Many large and even severe weather phenomena, such as cold and warm fronts, showers, thunderstorms, and hurricanes, are all powered by wind

3. Visibility –

Visibility may sound like a very unlikely feature of weather, but it is highly critical when discussing and calculating weather conditions such as fog, mist, freezing drizzle, and smog.

4. Precipitation –

Rainfall, Snow, Hail, or graupel

Precipitation is water in its multiple forms, which form after condensation, converting water vapour into its liquid or solid form, which falls to the earth after it becomes too hot to remain floating in the air.

5. Clouds –

Clouds are one of the best ways to assess present and predicted weather patterns.

Clouds are water droplets or water in various states (like ice and snow crystals) that emerged after water vapour had reached the level of condensation and could no longer exist in gaseous form.

6. Air pressure -

Air pressure is another main aspect of weather, particularly when it comes to developing or altering atmospheric conditions

Note:

Climate refers to the sum-total of environmental patterns and fluctuations over a wide region over a long period (more than thirty years).

Weather refers to the state of the ambient e over the area at any moment.

The elements of nature and climate are the same, i.e. temperature, air pressure, wind, humidity, and rainfall.

Answer 2

Explanation:

Weather influences our lives in different ways. During summer, we switch on fans to keep ourselves cool, we use light coloured clothes in order to reflect the heat. During winter, we use dark colour clothes and wrap ourselves in warm clothes to protect us from cold environment. Similarly, during the rainy season, we use umbrella or raincoat as it may rain anytime. The weather of a place changes day after day and week after week. It is a complex phenomenon that may vary over very short periods of time (like hour to hour).

Therefore, our daily activities are planned according to the weather predicted for a particular day. The daily report of weather is provided on television, radio and even in newspaper.
