Understanding the Water Cycle

What are the main stages of the water cycle?

• Filtration, absorption, evaporation, runoff

• Condensation, filtration, evaporation, storage

• Precipitation, evaporation, filtration, absorption

• Evaporation, condensation, precipitation, collection

Define evaporation and its role in the water cycle.

• Evaporation is the process of water turning into vapor, playing a key role in the water cycle by transferring water from the surface to the atmosphere.

• Evaporation is the process of water freezing into ice.

• Evaporation is the movement of vapor back to the surface.

• Evaporation occurs only during the night.

What is condensation and how does it occur?

• Condensation occurs only in high-pressure environments.

• Condensation is the process of water vapor turning into liquid water, occurring when air cools and loses energy.

• Condensation is the process of liquid water turning into water vapor when heated.

• Condensation is the evaporation of water from surfaces.

List the different types of precipitation.

• fog

• mist

• Rain, snow, sleet, hail, drizzle

• dew

How does the sun influence the water cycle?

• The sun absorbs water from the ground.

• The sun cools the water, causing condensation.

• The sun has no effect on the water cycle.

• The sun drives the water cycle by providing the energy for evaporation.

Explain the process of transpiration in plants.

• Transpiration is the absorption of water by plant roots.

• Transpiration is the process of photosynthesis in plants.

• Transpiration is the release of water vapor from plant leaves through stomata.

• Transpiration occurs only at night when plants are dormant.

What is the significance of groundwater in the water cycle?

• Groundwater is only a minor component of the water cycle.

• Groundwater is significant in the water cycle as it stores water, replenishes surface water bodies, and contributes to evaporation.

• Groundwater does not affect surface water bodies.

• Groundwater is primarily used for irrigation and has no role in evaporation.

Describe how water moves through an ecosystem.

• Water moves through an ecosystem only by rivers and lakes.

• Water is static and does not move through an ecosystem.

• Water moves through an ecosystem via the water cycle, involving evaporation, condensation, precipitation, infiltration, and runoff.

• Water is absorbed by plants and never returns to the atmosphere.

What role do clouds play in the water cycle?

• Clouds are formed only during storms and have no other function.

• Clouds absorb sunlight and increase temperatures.

• Clouds are primarily responsible for soil erosion.

• Clouds transport water vapor and release precipitation, playing a crucial role in the water cycle.

How does temperature affect evaporation rates?

• Higher temperatures increase evaporation rates due to increased molecular kinetic energy.

• Lower temperatures decrease evaporation rates due to reduced molecular kinetic energy.

• Higher humidity levels always increase evaporation rates regardless of temperature.

• Evaporation rates are unaffected by temperature changes.
