Summary

Water is essential for life on Earth, covering 70% of the surface but making up only 0.05% of the Earth's mass. The water cycle, also known as the hydrologic cycle, consists of five key stages: evaporation, condensation, precipitation, runoff, and percolation. Evaporation begins the cycle as water turns into vapor, and condensation forms clouds. Precipitation follows as rain, snow, or other forms. Runoff transports water to rivers and oceans, while percolation allows water to seep into the ground. This cycle sustains life and regulates Earth's environment.

Takeaways

• 😀 Water is the basic element of nature and covers 70% of Earth's surface, yet represents only 0.05% of Earth's total mass.
• 🌊 Earth's total volume of water is around 1.386 billion cubic kilometers (333 million cubic miles).
• 💧 97.5% of Earth's water is saltwater, while only 2.5% is fresh water.
• 🌍 A mere 0.03% of Earth's fresh water exists in liquid form, which is crucial for life.
• 🌞 The water cycle, also known as the hydrological cycle, consists of five key stages: evaporation, condensation, precipitation, runoff, and percolation.
• 🌫️ Evaporation is the process where water absorbs heat from the Sun and turns into vapor, mainly from bodies of water like oceans, seas, lakes, and rivers.
• ☁️ Condensation occurs when water vapor rises, cools, and forms tiny particles like ice or droplets, which gather to form clouds or fog.
• 🌧️ Precipitation happens when water droplets combine and fall as rain, snow, drizzle, sleet, or hail, depending on temperature.
• 🏞️ Runoff is the process where water flows over the Earth's surface, potentially displacing soil and leading to rivers, lakes, and oceans.
• 💧 Percolation describes water being absorbed into the ground, eventually becoming groundwater, completing the cycle.

Q & A

What percentage of the Earth's surface is covered by water?

Water covers 70% of the Earth's surface.

What is the total volume of water present on Earth?

The total volume of water present on Earth is approximately 1.386 billion cubic kilometers, or 333 million cubic miles.

What percentage of Earth's water is saltwater?

97.5% of Earth's water is saltwater.

How much of Earth's water is fresh water?

Only 2.5% of Earth's water is fresh water.

What percentage of fresh water is available in liquid form on Earth?

Only 0.03% of fresh water is available as liquid on Earth.

What are the five steps of the water cycle?

The five steps of the water cycle are evaporation, condensation, precipitation, runoff, and percolation.

What happens during evaporation in the water cycle?

During evaporation, water at the surface absorbs heat from the sun and turns into water vapor. This occurs mainly from bodies of water like oceans, seas, lakes, and rivers.

What is condensation in the water cycle?

Condensation is the process where water vapor rises and cools at high altitudes, turning into tiny water droplets or ice particles, which form clouds and fog.

How does precipitation occur in the water cycle?

Precipitation happens when water droplets in clouds combine and fall to the Earth as rain, snow, sleet, or hail, depending on the temperature.

What is runoff in the water cycle?

Runoff is the process where water runs over the Earth's surface, displacing soil and eventually flowing into rivers, lakes, seas, or oceans.
