Hydrologic Cycle Flashcards
(26 cards)
What is the hydrologic cycle?
The hydrologic cycle is the continuous movement of water on, above, and below the surface of the Earth.
True or False: The hydrologic cycle includes only liquid water.
False
Fill in the blank: The process by which water vapor turns into liquid water is called ______.
condensation
What are the main processes involved in the hydrologic cycle?
Evaporation, condensation, precipitation, infiltration, and runoff.
Multiple choice: Which of the following is NOT a part of the hydrologic cycle? A) Evaporation B) Photosynthesis C) Precipitation D) Runoff
B) Photosynthesis
What role do plants play in the hydrologic cycle?
Plants contribute through the process of transpiration, releasing water vapor into the atmosphere.
True or False: Groundwater is a part of the hydrologic cycle.
True
What is infiltration in the context of the hydrologic cycle?
Infiltration is the process by which water on the ground surface enters the soil.
Fill in the blank: The movement of water from the atmosphere to the Earth’s surface is called ______.
precipitation
What is runoff?
Runoff is the flow of water that occurs when excess rainwater, meltwater, or other sources flow over the Earth’s surface.
Multiple choice: Which process in the hydrologic cycle contributes to cloud formation? A) Infiltration B) Transpiration C) Evaporation D) Condensation
D) Condensation
What is the significance of the hydrologic cycle for ecosystems?
It supports life by distributing water, which is essential for all living organisms.
True or False: The hydrologic cycle can be affected by human activities.
True
What is evaporation?
Evaporation is the process by which water changes from a liquid to a gas or vapor.
Fill in the blank: The hydrologic cycle is powered primarily by ______.
solar energy
What is the term for water that is stored underground?
Groundwater
Multiple choice: Which of the following processes removes water from the soil? A) Infiltration B) Evaporation C) Precipitation D) Transpiration
B) Evaporation
What is the difference between surface water and groundwater?
Surface water is found in oceans, rivers, and lakes, while groundwater is stored in soil and rock formations underground.
True or False: The hydrologic cycle is a closed system.
True
What is precipitation?
Precipitation is any form of water, liquid or solid, that falls from the atmosphere to the Earth’s surface.
Fill in the blank: Water that evaporates from oceans is called ______.
water vapor
What is transpiration?
Transpiration is the process where water is absorbed by plants and released as water vapor through their leaves.
Multiple choice: Which factor can influence the rate of evaporation? A) Temperature B) Humidity C) Wind C) All of the above
D) All of the above
What happens to water during the condensation process?
Water vapor cools and changes back into liquid droplets, forming clouds.
