Water Distribution and Earth's Spheres

The video tutorial explores the distribution of water across Earth's spheres, including the hydrosphere, atmosphere, biosphere, cryosphere, and lithosphere. It highlights the limited availability of freshwater, with only 3% being fresh and a mere 1% accessible for human use. The tutorial uses visual tools to illustrate these concepts, emphasizing the importance of understanding water distribution for geographical studies.

What is the primary focus of the lesson on Earth's spheres?

• The formation of clouds in the atmosphere.

• The biodiversity in the biosphere.

• The types of rocks found in the lithosphere.

• The amount of water available on Earth and its distribution.

Which sphere contains all the surface water on Earth?

• Biosphere

• Hydrosphere

• Cryosphere

• Lithosphere

What is the role of the atmosphere in the water cycle?

• It holds all the living organisms.

• It stores all the groundwater.

• It contains clouds and water vapor.

• It is the main source of ice.
