Water cycle Flashcards
_____is the continuous process by which ____ is circulated between the Earth and the atmosphere.
It is a vital process that sustains life on Earth and helps regulate the planet’s climate.
Water cycle
The water cycle, also known as the _____
hydrologic cycle
What are stages of water cycle?
Evaporation
Condensation
Precipitation
Run-off
Infiltration
Percolation
Transpiration
What are the importance of water cycle?
Supports life
Regulates Climate
Shapes Landscape
Replenishes Groundwater
_____is the process by which water is transformed from a liquid to a gas state.
Evaporation
This occurs when the temperature and humidity are high enough to allow water molecules to escape into the air.
Evaporation
Evaporation occurs from various sources, including?
oceans, lakes, rivers, and the ground.
As water vapor rises into the air, it cools down, and its temperature decreases. When the air reaches its dew point, the water vapor condenses into tiny droplets, forming clouds.
Condensation
When the clouds become saturated with water, the droplets combine to form larger droplets, which eventually become too heavy to remain suspended in the air.
This leads to_____, which can take various forms, including rain, snow, sleet, and hail.
precipitation
Once the precipitation reaches the ground, it can flow over the surface as runoff or soak into the soil. _____ can collect in low-lying areas and flow into streams, rivers, and lakes.
Run -Off
____occurs when precipitation seeps into the soil and becomes groundwater.
Infiltration
This process helps recharge aquifers, which supply freshwater to wells and springs.
Infiltration
_____is the movement of water through the soil layers. As water infiltrates the soil, it can move downward through the soil layers, eventually becoming part of the groundwater.
Percolation
_____occurs when plants absorb water from the soil and release it into the air as water vapor.
Transpiration
This process is an important part of the water cycle, as it helps return water to the atmosphere.
Transpiration
What are the Human Factors Affecting
Water Cycle?
Deforestation
Urbanization
Agriculture
Pollution
Climate change
the process where water is released from plants into the atmosphere.
evapotranspiration
Clearing forests reduces evapotranspiration, the process where water is released from plants into the atmosphere. This decreases rainfall and increases runoff, leading to soil erosion and flooding.
Deforestation
Paved surfaces and buildings increase impervious areas, reducing infiltration and causing more runoff. This leads to water shortages during dry periods and increased flood risk during heavy rainfall.
URBANIZATION
Irrigation practices, particularly those using unsustainable methods, can deplete groundwater resources.
Excessive water use and pesticide runoff can contaminate water sources.
Agriculture
Industrial and agricultural waste, sewage, and chemical spills pollute rivers, lakes, and oceans, impacting water quality and harming aquatic life.
POLLUTION
Rising temperatures alter the water cycle, leading to more frequent and intense droughts and floods. Melting glaciers and ice caps contribute to sea-level rise, threatening coastal communities and ecosystems.

____plays a pivotal role in evaporation and transpiration. Higher temperatures increase the rate of evaporation from water bodies and transpiration from plants, leading to more water vapor in the atmosphere and potentially increased precipitation.
Conversely, lower temperatures reduce these rates
