Climate Flashcards
(17 cards)
What geographic feature forms India’s northern boundary?
The Himalayas
The Himalayas, along with other continuous mountains, create a climatic divide between the Indian Subcontinent and Central Asia.
How does the climate of the Himalayan mountain zone vary?
According to elevation and topography
Different parts of the region experience varying climatic conditions based on their elevation and geographical features.
What type of climate prevails along the lower mountain slopes and the Shiwalik foothills?
Mild climate
The lower elevations have milder temperatures compared to higher altitudes.
What climate conditions are experienced at higher elevations in the Himalayas?
Considerably low temperature and winter climate conditions
At extreme altitudes, particularly in the Ladakh region, very low temperatures and harsh winter conditions are common.
What type of climate is experienced in the Ladakh region?
Pole-like extreme winter climate
The Ladakh region is known for its extremely cold winters, resembling polar conditions.
Fill in the blank: The _______ mountain port (Shiwal) has a mild temperature.
Lower
The term ‘Lower’ refers to the lower mountain slopes where milder temperatures are found.
What characterizes the climate at very high altitudes in the Himalayas?
Extreme winter climate
Very high altitudes experience harsh winter conditions, significantly different from lower elevations.
What is a characteristic feature of Himalayan rivers?
Flood prone even during summer
Himalayan rivers experience flooding due to their turbulent flow and steep gradients.
What shapes do the valleys formed by Himalayan rivers resemble?
V-shaped valleys
These valleys have slanting sides and resemble the letter ‘V’.
What is a common cause of waterfalls in rivers?
Excessive erosion of soft rock
Waterfalls occur when water free falls vertically due to the erosion process.
What type of drainage system do the Himalayan rivers create?
Himalaya drainage system
This system includes major rivers and their tributaries like the Indus, Ganga, and Brahmaputra.
What are the characteristics of the rivers fed by rain and snow in the Himalayas?
Perennial (water rich)
These rivers are consistently fed by rainfall and melting snow.
Which region in India receives heavy rainfall and contributes to the drainage system?
North Eastern India, especially the Meghalaya Hills
This region is influenced by monsoon winds from the Bay of Bengal.
What meteorological phenomenon affects the moisture levels in North Eastern India?
South West Monsoon rains
These rains bring significant moisture, which often leads to heavy rainfall in the region.
What is the result of the monsoon winds blowing from the Bay of Bengal?
Most moisture reaches back to earth as rainfall
The geography of the region traps moisture, leading to substantial precipitation.
Fill in the blank: The valleys formed by the rivers in the Himalayas are known as _______.
V-shaped valleys
They are formed due to the processes of erosion and sediment deposition.
Why are there numerous hill stations in the Himalayas?
Due to favorable climate and geography
The cooler temperatures and scenic views attract tourism.
