The Fascinating Journey of Water Through Earth's Cycle

The video explains the water cycle, highlighting its ancient origins and continuous movement through flows and stores. It covers precipitation in various forms, water's journey on land, and processes like evaporation and transpiration. The cycle's complexity is explored, emphasizing its importance for life on Earth.

What is the primary reason life exists on Earth according to the video?

• The diversity of species

• The presence of oxygen

• The perfect water cycle

• The abundance of sunlight

What percentage of Earth's water is stored in the oceans?

• 80%

• 60%

Which of the following is NOT a form of precipitation?

• Hail

• Rain

• Fog

• Mist

What happens to precipitation that falls on hardscaped surfaces?

• It evaporates immediately

• It is absorbed by plants

• It infiltrates the soil

• It runs off

How does water move through soil and rock particles?

• By precipitation

• By evaporation

• By percolation

• By condensation

What is the process called when plants release water back into the atmosphere?

• Precipitation

• Evaporation

• Condensation

• Transpiration

What term describes the combination of evaporation from soil and water surfaces and transpiration from plants?

• Infiltration

• Precipitation

• Condensation

• Evapotranspiration

What causes water to evaporate into the atmosphere?

• Plant absorption

• Wind

• Sun's heat

• Gravity

What happens to water molecules after they evaporate?

• They form ice

• They are absorbed by plants

• They mix with smoke and dirt particles

• They become part of the ocean

What is the final step in the water cycle before precipitation occurs again?
