Flashcards

The Water Cycle

The process where water moves from the Earth's surface to the atmosphere and back again.

Evaporation

When liquid water changes into water vapor, rising into the air.

Condensation

When water vapor cools and changes back into liquid water, forming clouds.

Precipitation

The process where water droplets in clouds combine, becoming heavy and falling as rain, snow, or hail.

Explain the water cycle from a lake.

The water cycle is a continuous process that begins with water in lakes, oceans, and rivers. The sun's energy causes evaporation, then condensation forms clouds, and finally, precipitation brings water back to Earth.

Study Notes

Ecosystems: Cycles of Matter

  • Transpiration: Water evaporates from plant leaves, returning to the atmosphere.
  • Oxygen-Carbon Cycle: Living things use energy and release gas as waste. This cycle explains the circulation of these gases.
  • Nitrogen Cycle: A continuous circulation between soil, organisms, and air.
  • Water Cycle: Includes water vapor changing from gas to liquid (condensation).
  • Nitrogen in the Soil: Plants absorb nitrogen from the soil; animals consume plants for nitrogen intake. Animals do not directly absorb nitrogen from the soil.
  • Water Cycle Steps (in order):
    • Energy from the sun causes water to evaporate.
    • Water vapor cools and condenses to form clouds.
    • Droplets combine in clouds to grow larger.
    • Large water droplets fall to the ground.
  • Photosynthesis & Respiration: Green plants use sunlight, water, and carbon dioxide to create food, releasing oxygen. Animals utilize oxygen for energy, releasing carbon dioxide as waste.
  • Runoff: Rainwater flowing over Earth's surface, gathering in lakes and rivers.
