Fresh water made life possible for all species on the land, but it also taught humans about the cycles of time, life and death. Where streams and rivers ran, our ancestors learned to follow along side of such ways. The great tributaries became the focus of traveling, migration, hunting and...
There is more fresh water in the atmosphere than in all of the rivers on the planet combined.34 If all of the water vapor in the Earth’s atmosphere fell at once, distributed evenly, it would only cover the earth with about an inch of water.34 It takes seven and a half years for ...

Water vapor in the sky cools to form clouds. When these clouds get heavy with water droplets, we get rain. The air is cool and humid during rainy weather.We know that the weather keeps changing throughout the year. In some months, it is very hot. In some months, it is very cold ...
Water is a chemical substance. A single water molecule contains two hydrogen atoms and one oxygen atom bonded together. The chemical formula for water is H2O. Water can be in one of three states. Water can be in a liquid sate, gas state (vapor) or solid state. An example of water in...
Earth's atmosphere is made of mainly nitrogen (~78%) and oxygen (21%), with trace amounts of other gases such as argon, water vapor, carbon dioxide, methane, ozone, etc... How high does Earth's atmosphere go? Earth's atmosphere extends from the surface to a height of around 10,000...
One of the most exciting Saturn facts is about its moon Enceladus, which has geysers that eject large plumes of ice and water vapor into space. These plumes contribute to Saturn’s E-ring and could indicate the presence of a subsurface ocean. ...
But the ocean doesn’t simply store heat like a giant, watery furnace. It’s a master at sharing that warmth worldwide. Fun fact: almost all rainfall begins its journey as oceanic vapor! It’s no wonder the tropics get so much rain since this is where the ocean’s heat absorption and...
Vape pens are also water resistant, ensuring your pen remains intact even when exposed to water; hence, you can clean it up using a cloth and water.Image source3. Have Different WattagesBuyers usually have different preferences on the size of vapor they want to produce. Notably, vape pens ...
1-2% water vapor, carbon dioxide & other gases The “ingredients” in the air don’t change when it’s compressed—just the amount of space those molecules take up. How is air compressed? Air is compressed in two simple steps: Step 1: Air is trapped in a cylinder, tank, or similar ...
