Answers:
- The water cycle is the continuous process of water movement on, above, and below the Earth's surface, involving phases like evaporation, condensation, precipitation, and runoff.
- The water cycle starts with the process of evaporation, where water from oceans, lakes, and other bodies of water turns into water vapor due to the sun's heat.
- During condensation, water vapor in the atmosphere cools down and transforms back into liquid water, forming clouds.
- Precipitation refers to any form of water, such as rain, snow, sleet, or hail, that falls from clouds and reaches the Earth's surface.
- Transpiration is the process by which plants release water vapor into the atmosphere through their leaves, contributing to the water cycle.
- Runoff happens when excess water from rain or melting snow flows over the land and doesn't get absorbed, ultimately reaching rivers, lakes, and oceans.
- Infiltration occurs when water seeps into the ground and gets absorbed by the soil and rocks, becoming groundwater.
- Sublimation is when water changes from a solid (ice or snow) directly into water vapor without becoming liquid first.
- Clouds form when water vapor in the air condenses around tiny particles, such as dust or smoke, to create visible water droplets or ice crystals.
- Temperature, humidity, and wind speed are factors that can influence the rate of evaporation.
- The water cycle influences weather patterns by redistributing moisture in the atmosphere, which affects cloud formation and precipitation.
- The water cycle is essential for life as it sustains the availability of fresh water, which is vital for all living organisms.
- The sun's energy drives the water cycle by providing heat, which causes evaporation and powers the entire process.
- The water cycle affects ecosystems by providing water for plants and animals, influencing climate, and shaping habitats.
- Renewable sources of water include rainfall and groundwater, which replenish over time.
- Non-renewable sources of water include ancient groundwater trapped in aquifers that cannot be replenished in a human-relevant timescale.
- Human activities, such as deforestation, pollution, and excessive water use, can disrupt the water cycle and lead to environmental problems.
- Conserving water through practices like fixing leaks, using water-saving appliances, and reducing water waste helps maintain a healthy water cycle.
- The different forms of precipitation are rain, snow, sleet, and hail.
- The water cycle connects different bodies of water by transporting water through various processes, allowing water to move from oceans to the atmosphere, to the land, and back again.
