C. Answer the following questions in short:
1. Write two differences between climate and weather.
2. How do organisms living in cold climates adapt themselves?
3. What is adaptation?
Answers
Answer:
1. Weather reflects short-term conditions of the atmosphere while climate is the average daily weather for an extended period of time at a certain location. ... Weather can change from minute-to-minute, hour-to-hour, day-to-day, and season-to-season. Climate, is the average of weather over time and space.
2.How do organisms living in cold climates adapt themselves?
3.Adaptation is an evolutionary process where a plant or an animal becomes suited to living in a particular habitat. These are changes that take place over many generations through natural selection. Changes may be physical or behavioural.
Answer:
1.The primary difference between weather, and climate is the duration over which they are measured. Weather includes the short-term changes of the atmospheric conditions, while climate is the observation of weather for a longer-term. Similar to the climate weather difference, the season is different from the climate.
2.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.
3.Adaptation is the physical or behavioural characteristic of an organism that helps an organism to survive better in the surrounding environment
