ViviThe total amount of water on Earth remains relatively constant over time due to the water cycle, which involves processes like evaporation, condensation, and precipitation. While water may change form or location (e.g., from liquid to vapor), the overall quantity of water on Earth remains stable.

Is the amount of water in earth's atmosphere and on earth always the same?
Yes - the Earth has a finite amount of water on it. This water cycles between the oceans and the atmosphere.
Why the earth is also known as water planet?
Earth is known as the water planet because about 71% of its surface is covered by water, mostly in the form of oceans. Water plays a crucial role in supporting life on Earth, regulating the climate, and shaping the planet's physical features. This abundance of water distinguishes Earth from other planets in our solar system.
How much water is there on earth today compared to 100 years ago?
The total amount of water on Earth has remained relatively constant over the past 100 years. However, changes in the distribution of water due to activities like urbanization and climate change may have altered the availability of freshwater in some regions.
Which planet's water resources might be close to the amount on Earth?
Jupiter's moon Europa is believed to have a subsurface ocean that could potentially contain as much water as all of Earth's oceans combined. This makes it one of the best candidates for hosting liquid water in our solar system outside of Earth.
How does the atmosphere prevent us from getting too hot during the day?
The atmosphere absorbs and scatters incoming solar radiation, limiting the amount of heat that reaches the Earth's surface. It also helps regulate temperatures by trapping some of the heat radiated by the Earth, preventing it from escaping too quickly. Additionally, the atmosphere contains gases like water vapor and carbon dioxide that contribute to the greenhouse effect, which helps maintain Earth's temperatures within a habitable range.
