Explanation:
1] Weather is the mix of events that happen each day in our atmosphere. Weather is different in different parts of the world and changes over minutes, hours, days and weeks. Most weather happens in the troposphere, the part of Earth's atmosphere that is closest to the ground.
2] There are six main components, or parts, of weather. They are temperature, atmospheric pressure, wind, humidity, precipitation, and cloudiness.
3] Six's thermometer is a registering thermometer which can record the maximum and minimum temperatures
4] Climate is the long-term average of weather, typically averaged over a period of 30 years. More rigorously, it denotes the mean and variability of meteorological variables over a time spanning from months to millions of years.
5] the action or process of adapting or being adapted.
6] Their adaptations include:
a white appearance - as camouflage from prey on the snow and ice.
thick layers of fat and fur - for insulation against the cold.
a small surface area to volume ratio - to minimise heat loss.
7] Reasons to Move. Some animals travel relatively short distances to find food or more favorable living or breeding conditions. Most animals that migrate do so to find food or more livable conditions. Some animals migrate to breed.
Answer :
★ Answer the following Questions :-
1. Define weather.
➠ it is the daily state of the atmosphere in a particular place, which can be sunny, wet, bright or cloudy is called weather.
2. What are the different elements of weather ?
➠ The different elements of weather is :-
- Atmosphere pressure
- Temperature
- Humidity
- Wind
- Precipitation
- Cloudiness
3. What is the maximum-minimum thermometer ?
➠ The maximum-minimum temperature are the highest-slowest temperatures which is used to record any temperature of a particular place or thing.
4. What do you mean by climate ?
➠ The weather conditions at a particular place over a long term of time ( 20-30 years ) is called climate. The climate of a place depends upon :-
- Distance from the Equator
- The height of the place
- Distance from the sea.
5. What is adaptation ?
➠ The ability of an organism to change for better adjustment with the environment is called adaptation.
6. List three adaptive features of polar bear.
➠ The three adaptive features of polar bear are :-
- Their body is covered with thick skin or to protect them from cold.
- They have small ears and nose to reduce heat loss from their body.
- They also have a thick layer of fat under the skin for insulation and protecting from cold.
7. Why do some animals and birds migrate during cold season ?
➠ Habitats have special features and behaviour to help the organisms to adapt themselves to those conditions. adaptation helps an organism to live successfully in its habitat. The organisms that fails to adjust itself to its surroundings cannot survive so some animals and birds migrate during cold season.
