(f) Why is the Northern Hemisphere called the Land Hemisphere?
(g) Why is the biosphere important for living organisms?
(a)
The four major domains of the Earth are: lithosphere, hydrosphere,
atmosphere and biosphere.
(b)
The seven major continents of the Earth are: Asia, Europe, Africa,
North America, South America, Australia and Antarctica.
(c)
The two continents that lie entirely in the Southern Hemisphere are:
Australia and Antarctica.
(d)
The different layers of atmosphere are: troposphere, stratosphere,
mesosphere, thermosphere and exosphere.
(e)
The Earth is called the ‘blue planet’ because more than
71 per cent of its surface is covered with water.
(f)
The Northern Hemisphere is called the Land Hemisphere because the
greater part of Earth’s landmass lies in the Northern
Hemisphere.
(g)The biosphere is the narrow zone of
contact between land, water and air. It is in this zone that life,
that is unique to Earth, exists. All the living organisms are linked
to each other and to the biosphere for survival.
