➡ Here's your answer

↪Elements of weather are;

◾ Temperature;

Temperature changes during 24 hours are very significant . Morning are the coolest . As the sun rises , temperature also rises gradually till noon due to heat coming out from the sun rays . The temperature becomes maximum in the afternoon . When heat escapes during night the temperature falls and is the lowest in early mornings.

⚫Thus temperature varies according to the heat generated throughout the day and the coolness at night.

◾Humidity

the amount of water vapours for present in the atmosphere are called humidity. The capacity of air to hold water vapour increases with the rise of temperature .

⚫ humidity is measured by a device called hygrometer.

◾Rainfall;

When hair with 100% humidity cools down, that is, water vapour condenses that is changes into water droplets . The mass of water droplets forms clouds. Further cooling causes this water droplets to pour down as rain .

⚫ Rainfall is measured by rain gague. It is measured in millimeters.

◾Wind

Moving air is called wind . It is caused due to the difference in temperature in the air . Wind is another major element of weather.

⚫ The wind causes are the components of weather success clouds and rain to occur .

⚫ Places, closer to the ocean, are often very windy. These places experience sea breeze and land breeze everyday because of the difference in temperature between the land and the sea.

⚫ The instrument used to measure wind speed is called an anemometer . The anemometer rotates at the same speed as wind.

Answer 2

there are several types of elements but most important elements are:-

(1) Temperature:-It is a physical quantity which express hot and cold. It is measured by an instrument know as thermometer.It can be expressed in common scales that is Celsius (denoted by c°)and Fahrenheit (f°) and Kelvin (K).

(2)Wind:-Wind is the flow of the various gases around our earth.It consist of various gases that is Very important in our life such that oxygen,carbondioxie, nitrogen etc.It also help in the transfer of sounds from one place to another.

(3) Atmospheric pressure:-The pressure exerted by the weight of atmosphere is known as atmospheric pressure.The earth is covered in a layer of air. At different places, the layer of air is thicker and in some places the layer of air is higher. Where the layer of air is thicker, there is more air. Since there is more air, there is a higher pressure in that spot. Where the layer of air is thinner, there is a lower atmospheric pressure.

(4) Humidity:-The quantity which representing the amount of water vapour in the atmosphere or in a gas is known as Humidity. Water vapour generally present in gaseous form or state of water.it is one of the fundamental abiotic factors that defines any habitat and is a determinant of which animals and plants can thrive in a given environment.
