CLIMATE-CLASS-9: CBSE- part 2

This video is uploaded by " HAMSIKA ACADEMY", TO HELP STUDENTS OF CBSE-CBSE Curriculum
The curriculum refers to the lessons and academic content to be taught to a learner in the
school. In empirical terms, it may be regarded as the sum total of a planned set of
educational experiences provided to a learner by a school. It encompasses general
objectives of learning, courses of study, subject-wise instructional objectives and content,
pedagogical practices and assessment guidelines. The curriculum provided by CBSE is based on National Curriculum Framework-2005 and seeks to provide opportunities for students to achieve excellence in learning.The Secondary School Curriculum acknowledges the fact that subjects like language,
Mathematics, Science and social science help the cognitive development of the child and,
therefore, require a greater academic emphasis. Further, CBSE also envisions the all-round development of students in consonance with the holistic approach to education and therefore,
emphasizes integration of co-curricular domains with curricular activities in an equitable manner.
In operational sense, the secondary curriculum is learner-centered with school being a place
where students would be acquiring various skills; building self-concept, sense of enterprise, aesthetic sensibilities, and sportsmanship. Therefore, for the purpose of fostering core
competencies in learners, this curriculum encompasses even major learning areas, from
the scholastic and co-scholastic point of view. The Areas of learning at the Secondary level areas We as a layman often confuse between climate and weather and use these words synonymously, however, these have different meanings. Let’s look at these brief notes on Climate Class 9 to understand the concept in its literal sense.

Weather is the state of atmosphere recorded at any given point of time. It can change every moment and varies throughout the day. Whereas, the Climate of a place is the sum of average weather conditions of 30 years, in short, the climate is a sum total of the weather conditions of a place, assertively a large one for a comparatively longer period of time. It can take millions of years for the climate of a place to change.

The Elements of Climate and Weather are same, which are:

Temperature
Atmospheric Pressure
Wind
Humidity
Precipitation
Note: According to the monthly atmospheric conditions of a place a year is divided into three seasons, namely- Summer, Winter, Rainy.

The Climatic conditions of any place depending on the following common factors:

Latitude
Altitude
Distance from the sea
Pressure and wind systems
Ocean Currents
Relief Features
In particular to a country like India, the factors that are considered to affect the climatic conditions are- Latitude, Altitude, Pressure, and Winds, which means it is influenced by pressure and surface winds, upper air circulation, western cyclonic disturbances and tropical cyclones.

Quick Facts About Indian Climate
The climate of India is described as the “Monsoon” type of climate which is most prevalent in South and South East Asia. This is because the climate of India is influenced by the monsoon winds, which is basically a seasonal reversal in the wind through the year
Tropic of cancer passes through the middle of India from Rann of Kutch to Mizoram. When the sun is directly overhead on the Tropic of cancer which is June 21, it marks the beginning of summer in the Northern hemisphere
Temperature and precipitation are the elements which are taken into consideration to ascertain the varying climatic condition from place to place and season to season
The Himalayas prevent the cold Katabatic winds from entering the Indian sub-continent
Jet streams are fast flowing and narrow air currents which flow at a high altitude of about 12000 feet in the troposphere
Coriolis Force is an apparent force caused by the earth’s rotation. Due to this force, the winds are deflected towards the right in the northern hemisphere and towards the left in the southern hemisphere, this mechanism is known as ‘Ferrel’s Law’
The western cyclonic disturbances are weather phenomena of the winter months brought in by the westerly flow from the Mediterranean region, which influences the weather of the north and north-western regions of India.
A broad trough of low pressure in equatorial latitudes is known as Inter-Tropical Convergence Zone (ITCZ), where the northeast and southeast trade winds converge
The east to west region in the Northern plains experiences decrease in rainfall
Ocean currents influence the climate of coastal regions
Indian climatic region also experiences the concept of continentality which means that the people residing far away from the sea experiences extreme weather conditions
