What is the primary characteristic of the Tundra region during winter?
It is extremely cold and almost dark throughout November, December, and January.
The sun does not rise at all during these months.
What happens to water bodies in the Tundra during winter?
Rivers, lakes, and seas freeze due to extreme cold.
Water transforms into ice in these conditions.
What climatic conditions are experienced in the Tundra during winter?
Strong cold winds blow and there is heavy snowfall.
These conditions lead to dark and icy environments.
What happens to plants and animals in the Tundra during winter?
All plants die, and birds and animals migrate elsewhere.
The region becomes dark, deserted, and desolate.
When does the sun begin to shine in the Tundra?
Around February-March.
Initially, the sun shines for a maximum of an hour and a half.
How does the duration of sunlight change in the Tundra as summer approaches?
It gradually increases to 2 hours, 6 hours, 8 hours, 16 hours, and finally 24 hours.
For almost three months from May to July, the sun never sets.
What is the position of the sun in the sky during summer in the Tundra?
The sun hovers just above the horizon and does not rise overhead.
The horizon is where the earth appears to meet the sky.
What happens to the ice during the summer in the Tundra?
Some ice melts, rivers begin to flow, and lakes fill up.
Huge chunks of ice break off and float into the ocean as icebergs.
What occurs to the landscape in the Tundra during summer?
The land comes alive with colour as multi-coloured plants, lichens, grass, shrubs, and berries sprout.
These plants bear flowers and fruits of different colours.
What is ‘permafrost’?
The upper soil surface of the Tundra region that is frozen into a rock-like state all through the year.
This phenomenon is due to the extreme cold of the region.
