CBSE Class 7 Science Notes Chapter 7
Weather
Weather is defined as the atmospheric condition of any place regularly and is determined by various factors, including humidity, temperature, wind speed, etc.
The daily condition of the atmosphere at a place, determined by variables like temperature, humidity, wind speed, and so forth, is called the weather .
A device known as a
hygrometer
is used to measure humidity, which is the amount of water vapour in the atmosphere.
The average weather at a certain place over an extended period is referred to as the climate.
Fronts and Weather Conditions
Weather is produced by the interaction of several factors, including:
A location's weather is never continuous. It may change once a day or even once an hour. For example, in some places, it may be sunny in the morning but cloudy in the evening.
A minimum-maximum thermometer is used to measure the minimum and maximum temperatures of the day, which are always included in a location's weather report. The morning hours are when the lowest temperature is felt, and the afternoon hours are when the highest temperature is felt.
- temperature or heat
- humidity or amount of water vapour in the air
- wind and atmospheric pressure.
- precipitation or the amount of rain
- cloudiness or the amount of cloud cover
- visibility is how far you can look into the horizon
- Wind and atmospheric pressure
Weather vs Climate
- Meteorologists record the weather every day.
- The records of the weather have been preserved for the past several decades.
- These help us to determine the weather pattern at a place.
- The average of the weather pattern over some time is determined by the climate.
| Basis | Climate | Weather |
| Definition | The average condition expected at a particular place in a given timeframe | The atmospheric condition at a particular point in time |
| Projection | carried out using the total of weather statistics over a time frame of 30 years | carried out by collating data regarding meteorology, such as solar radiation, air temperature, humidity, pressure, speed of the wind and its direction |
| Underlying Factors | The total weather statistics for the time frame of 30 years | Periodic measurements of atmospheric pressure, rainfall, speed and direction of the wind, humidity overcasts and other unstable factors |
| Study-subject | Climatology | Meteorology |
| Ingredients | comprises elements like humidity, rainfall, sunlight, wind speed, a natural phenomenon like fog, frost and so on in a particular period | comprises weather elements such as overcasts, rainfall, floods, hailstorms, winds, heatwaves, snowfall and many more |
| Time frame | Estimated over a longer period | Estimated over a shorter period |
Meteorology and Climatology
Weather forecasting is meteorology's primary concern. The government's Meteorological Department prepares the daily weather bulletins. This division gathers meteorological data, such as wind and temperature, and forecasts the weather. The study of climate, which is defined as average weather over a given period, is known as climatology.Formation and Types of Clouds
Convection is a process by which clouds form. The warm air that is directly over the ground and heated by the sun tends to get lighter and is lifted upwards with the warm air. The temperature drops as air rises higher, which reduces the air's capacity to hold water vapour. This vapour quickly condenses to form clouds, which are composed of billions of tiny water droplets or ice crystals. When air passes over hills or mountains, it is forced upward, which creates clouds. On a mountain's windward side, clouds and precipitation are common.Climate-Altering Factor
Topography is the term used to describe the form of the land. Sea Level: A region's distance from the sea and other nearby bodies of water has a significant impact on its climate. Ocean Currents: The temperature of a place can be affected by the movement of heat from the land to the sea or vice versa. Even though the aforementioned variables are all-natural, one of the most harmful ones that have caused this climate change is us, humans. Climate Adaptations: An animal's ability to survive in a particular climate is aided by its traits and behaviours.Adaptation has Led to the Classification of Three Regions
Polar Regions: The polar regions have a severe climate. At the poles, the sun never rises or sets for a combined total of six months. Tropical Rainforest: The tropical rainforest experiences extremely rainy and scorching summers. The length of the days and nights is roughly equal throughout the year. Desert: The weather in this area is severe. There's lots of sunshine and not much rain.Tropical Rainforests
Being close to the equator means that the tropical regions of the globe receive more sunshine throughout the year. These places experience a hot environment as a result. In tropical areas, the temperature might go up to 40 °C and barely decrease to 15 °C. In these areas, day and night are nearly identical in duration. However, because of the abundant rainfall, this area is home to tropical rainforests. There is a great diversity of plants and animals found in the tropical rainforests. Because of the dense population, animals in these areas frequently face competition for food. Numerous animals have modified themselves to enable them to dwell on trees and have easy access to food. These animals' skin tones are typically comparable to those of their surroundings, which helps them to both obtain prey and fend off predators. Numerous of these animals also have superior hearing and vision.Migration
It is the extensive migration of animals, particularly birds, from colder to warmer climates to reproduce, avoid the cold, or deal with a shortage of food.
Birds follow the light of the stars at night, and the light of the sun during the day. A Siberian crane travels from Siberia to India once a year.
Animal Adaptation
The secret to surviving on Earth is the capacity to adjust to harsh weather patterns. For instance, to defend oneself from predators, polar bears have evolved to develop long, white fur. Their survival in the frigid arctic areas is aided by the substantial amount of fat beneath their epidermis. Every species on the planet has evolved certain traits to help them thrive in their particular environments.Tropical Rainforests
The areas surrounding the equator, where temperatures are consistently very high, are home to tropical rainforests. The temperature drops below 15°C in the winter and rises to above 40°C in the summer.Desert
The climate of these regions is extremely hot and arid because of continuous exposure to sunlight and minimum rainfall.Benefits of CBSE Class 7 Science Notes Chapter 7
