Question

More than 70% of the world's freshwater is contained in
A. Polar ice
B. Antarctica
C. Green land
D. Glaciers and mountains

Answer 1

Except for seawater or brackish water, any naturally occurring water is known as freshwater. They are characterized by low salt concentrations. In the oceans and rivers, about $97$ of the earth's water is saline.

Complete answer:
Option A - The polar ice cap is known as the high-altitude area along with the dwarf planet or the ice sheet-covered natural satellite. About $70$ of the earth's freshwater is kept along with the polar ice caps. This is, therefore, the correct choice.
Option B-Around $68$of the land in the Antarctic forms the Antarctic ice sheet. Around $61$ of the freshwater is deposited in the Antarctic region's ice sheets. Therefore, this is the wrong option.
Option C-The Greenland is the largest island in the world, situated in the Arctic and Antarctic regions. Greenland is more like an area covered with ice. This is therefore the wrong option.
Option D-The glaciers are characterized as an enormous mass of ice that slides down the mountainous regions. This term is derived from the French word 'glace,' which means frost. This is therefore the incorrect choice.
So, Option (A), i.e., Polar ice is the correct answer to the given question.

Note: The gross dissolved solids are also poor in freshwater. It is also noted that about $70$ of the surface of the earth is covered by water, only $2.5$ of it is accessible as freshwater. They hold and clean the water that is important for wildlife and humans. Three-fourths of the planet (about $71$ of the total) is covered by oceans that hold $97.5$ of total water. Safe freshwater ecosystems provide water for drinking, growing crops, manufacturing, energy, and transport.
