Weather, climate and adaptation of animals (Points to remember)

Weather: Is the state of the atmospheric condition at a particular place at a given time. Weather changes every day

Climate: Climate is the average weather condition of a place over a long period of time. Climate generally remain unchanged for few days

Hygrometer: Humidity is measured by an instrument called a hygrometer and rainfall is measured by an instrument called a rain gauge.

Nocturnal animals: Animals living in hot climates such as snakes and the desert fox came out at night for hunting these animals are called nocturnal animals.

Adaptation: A special feature displayed by an organism to live and reproduce successfully in a particular environment.

Blubber: Thick deposit of fat under the skin in animals and birds living in a polar region

Relative Humidity: The ratio of the amount of water vapor in the air at a particular temperature to the maximum amount of water vapor the air can hold at that temperature.

Rainfall is measured by an instrument called the rain gauge.

WEATHER

The day-to-day condition of the atmosphere at a place with respect to the temperature, humidity, rainfall, wind speed, etc., is called the weather at that place. The temperature, humidity, and other factors are called the elements of the weather. The weather of a place changes day after day and week after week. That is why we often say, “today’s weather is too humid”, or “the weather was warm last week”. All changes in the weather are caused by the sun.

CLIMATE

The average weather pattern taken over a long time, say 25 years, is called the climate of the place.

Climate has a profound effect on all living organisms. Animals are adapted to survive in the conditions in which they live. Animals living in very cold and hot climates must possess special features to protect themselves against extreme cold or heat.

The polar regions present an extreme climate. These regions are covered with snow and it is very cold for the most part of the year. For six months the sun does not set at the poles while for the other six months the sun does not rise.

The tropical region has generally a hot climate because of its location around the equator. Even in the coldest month, the temperature is generally higher than about 15°C. During hot summers, the temperature may cross 40°C. Days and nights are almost equal in length throughout the year.
