ATMOSPHERIC CONDITION-SCIENCE BLOG

INTRODUCTION

Weather makes our living style in various way. During summer season, we feel very hot. That is why we switch fan or use refrigerated cool water. This time we  use to wear light colored cloth which  reflects the heat. Sometime there may be abnormalities of atmosphere. When the atmospheric condition is cold, then we use to wrap warm clothes which makes us hot.  In same way, during rainy season or humidity, we use umbrella or rainy coat  to protect ourselves from rain.

DEFINITION OF WEATHER

The weather of a place changes every day that may differ in very short periods like hour to hour. That is why, we plan our daily activities according to the weather forecasting for a particular day. We may define weather the condition of every day atmosphere of a certain place along with temperature, rainfall, humidity, wind speed etc.

ELEMENTS OF WEATHER IN ATMOSPHERIC CONDITION

Here I am trying to describe various elements in weather.

TEMPERATURE

Sun rays produces heat and makes rising of temperature of the earth. It is necessary to produce energy. Earth’s surface, ocean absorbs the heat. Therefore, temperature of the earth rises . As the time of sunrise and sunset changes throughout the year, the temperature also changes.

RAINFALL

Water vapor condenses as cloud. It falls back on the surface of the earth as rain droplets. When  the temperature is very low, then droplets present in the cloud becomes freezed into ice crystals. Due to gravity, it comes on the earth as snowfall. During winter,the atmospheric condition of after sunset the temperature becomes lower. It causes condensation of water vapor just above the ground surface. These droplets use to hang in the air just above the surface which forms fog and increases humidity.

HUMIDITY

It causes dampness of air if humidity is present  more in amount in the air. The capacity  of air to hold water vapor increases with the temperature rise followed by increase of humidity. This capacity also falls when there is heavy rainfall. We can measure amount of humidity by the help of hygrometer.  

WIND SPEED

If there is a difference in air pressure, then wind  blows in speed. In summer season wind blows from the sea and causes rainfall when it carries maximum amount of water vapor humidity. During storm or cyclone there may be abnormalities of atmosphere.

FACTORS DETERMINING THE CLIMATE IN WEATHER IN ATMOSPHERIC CONDITION

There are some factors for climate

DISTANCE FROM THE SEA

if a place is nearer to the sea then climate of that place is moderate or not much hot or cold. If a place is far away from the sea, then it has extreme climate that means very hot summer or very cold winter.

ALTITUDE ABOVE SEA LEVEL

Altitude determines a lot on climate. In very high altitude, the climate is very cold as in Himalaya. It may differ during abnormalities of atmosphere.

HUMIDITY

Place nearer to the  sea contains much amount of water vapor, so these places are very humid like Kerala. But the place far away from the sea contains less amount of water vapor so less humidity. These place is very dry like Haryana .

ANSWER IN BRIEF

Qs1: In atmospheric condition , why is it difficult to predict the weather of a place while it is easy to predict its climate?

Ans1: Weather is a type of event for very short duration. For this reason, it is difficult to predict the weather of a place. But we can easily predict climate as it is very easy work to us, because climate is measured by the average pattern weather for long duration.

 Qs2: For changing of weather the sun is an important factor. Explain briefly.

 Ans2: The sun plays an important role for changing the weather. The sun is a big star with full of hot gases, which produces light and heat. That helps us a lot. The energy from the sun is absorbed and reflected by the earth’s surface, ocean etc. It determines the weather condition of a certain place.. When the water vapor rises high in the atmosphere, it causes rain to come down on the earth. The hot air even develops areas of high and low pressure which follows formation of weather with high speed wind . It may cause abnormalities of atmosphere.

 DIFFERENTIATE BETWEEN THE FOLLOWING IN THE ATMOSPHERIC CONDITION

Qs3: Differentiate between  weather and climate in atmospheric condition .

Ans3:

WEATHER	CLIMATE
We may define as every day atmospheric condition of a certain place.	It is the average weather pattern taken over a long period of time like 25 years.
Weather  changes for short duration.	This factor varies for long time period.
It cannot affect the adaptation of an organism.	Climate  is a factor helping in adaptation and adjustment of plants and animals.

Qs4: Differentiate between humidity and rainfall .

Ans4:

HUMIDITY	RAINFALL
We define humidity as content of moisture in the atmosphere causing wetness of surrounding.	It is the drop of water falls from clouds on the ground.

Qs5: How do you differentiate polar region climate to tropical rainforest climate in atmospheric condition ?

 Ans5:

CLIMATE OF POLAR REGION	CLIMATE OF TROPICAL RAINFOREST
The climate of this region is very cold for most of the year.	In this place the climate is very hot and humid.

Qs6: Differentiate between maximum temperature of the day and minimum temperature of the day in atmospheric condition .

Ans6:

MAXIMUM TEMPERATURE OF THE DAY	MINIMUM TEMPERATURE OF THE DAY
Highest recorded temperature in a day.	Lowest  recorded temperature in a day.

CONCEPTUAL QUESTIONS IN ATMOSPHERIC CONDITION:

Qs7: Write the factors which affects the climate of a particular place.

Ans7: The factors that affect the climate of a place are:(i) Temperature zone or latitude, that means amount of sunshine it receives or distance from equator.

 Altitude of the place from the level of sea.

Amount of moisture found in air.

How much rainfall present .

Qs8: The animals living in rainforest adapt themselves to the climate present there.  Mention their adaptive features in such climate.

 Ans8: Those animals that live in tropical rainforests are herbivorous that are able to eat the vegetation, rich in rainforest. Most of the tropical rainforest animals walk on the land or are  adapted to live on trees. The rainforest dweller animals are good in vision, and well developed audible system. These characters help them to hunt their prey and protect from their enemies. They can adapt well even in abnormalities of atmosphere.
