1.2.1 The Water Cycle

• The water cycle is crucial for maintaining Earth's life support systems.

  True
• The water cycle regulates Earth's climate.


  True
• The water cycle replenishes freshwater supplies.


  True
• In what form does water return to Earth during precipitation?

  Rain, snow, sleet, or hail
• What is the definition of evaporation?

  Liquid to water vapor
• What is the dew point in the condensation process?

  Temperature of saturation
• The type of precipitation depends on temperature and humidity conditions.


  True
• The type of precipitation depends on temperature and humidity conditions in the atmosphere.


  True
• Precipitation is an essential part of the water cycle.


  True
• The release of water vapor from plants into the atmosphere is called transpiration
• What is the primary factor that influences the rate of evaporation?

  Temperature
• Match the process with its description.

  Condensation ↔️ Water vapor to liquid

  Evaporation ↔️ Liquid water to vapor
• Rain consists of liquid water droplets that fall from clouds.

  True
• Transpiration is the process where plants release water vapor into the atmosphere
• How does transpiration contribute to the water cycle?

  Returns water vapor
• Infiltration reduces surface runoff and replenishes groundwater reserves.


  True
• What primary process does the sun drive in the water cycle?

  Evaporation
• What is the role of evaporation in the water cycle?

  Converts liquid water
• What is the water cycle defined as?

  The continuous movement of water
• What are the main processes involved in the water cycle?

  Evaporation, transpiration, precipitation
• Precipitation can occur in the form of rain, snow, sleet, or hail
• The rate of transpiration is influenced by factors such as temperature, humidity, and wind speed
• Sandy soils have higher infiltration rates due to their large pore spaces
• Dry soils have a higher infiltration capacity
• Flat surfaces allow water to accumulate and infiltrate, while steep slopes promote runoff.
• What are underground layers of permeable rock or sediment that hold groundwater called?

  Aquifer systems
• Aquifers are classified as either confined or unconfined.


  True
• Without the sun's heat, the water cycle would not function.

  True
• Plants release water vapor into the atmosphere through transpiration.
• Urbanization increases impervious surfaces, reducing groundwater recharge.
• The water cycle is the continuous movement of water on, above, and below the Earth's surface
• What drives evaporation in the water cycle?

  Heat from the sun
• Match the process with its description:

  Evaporation ↔️ Liquid to water vapor

  Transpiration ↔️ Water vapor from plants

  Precipitation ↔️ Water returns to Earth
• Water vapor is released from plants into the atmosphere through the process of transpiration
• Arrange the following processes in the correct order as they occur in the water cycle:

  1️⃣ Evaporation

  2️⃣ Transpiration

  3️⃣ Precipitation

  4️⃣ Surface runoff

  5️⃣ Groundwater flow
• Higher temperatures increase the rate of evaporation
• Higher humidity increases the likelihood of condensation
• Precipitation occurs when water vapor in the atmosphere condenses
• Snow consists of solid ice crystals
• The water cycle maintains Earth's life support systems by replenishing freshwater
