What did ancient people believe about the water cycle?

What is the hydrologic cycle? Plato and other Greek philosophers believed that springs and rivers originated from purified sea water transported underground. Aristotle improved the theory by suggesting vapor transport through caverns from the sea and condensation at springs.

How did Bernard Palissy discover the water cycle?

Palissy was the first person to consider the water cycle. He wasn’t very smart so he had to rely on his opinion most of the time. When he observed some coastal areas, he found out it had salt water and fresh water. He presumed the fresh water was coming from the rainfall.

What do you understand by water cycle?

The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.

What is the conclusion of water cycle?

Answer: The hydrologic cycle is the process by which water circulates around the Earth. 90% of this water vapor returns to the ocean and 10% returns to the land as precipitation. (3) Runoff: Water either from the land’s surface (i.e., rivers) or as groundwater makes its way to the ocean.

What did ancient people believe about the water cycle? – Related Questions

What is water cycle in 5 sentence?

Answer: Water cycle in nature includes evaporation, condensation, precipitation. Trees and plants also evaporate by the process of transpiration. Water cycle describes the continuous movement of water below and above the earth which helps in recycling of water.

What is water cycle for Class 6?

Answer: The constant movement of water from the Earth to the atmosphere and back to the Earth through the process of evaporation, condensation and precipitation is known as the water cycle.

What does water cycle Class 9 mean?

What is Water Cycle? The water cycle, also known as the hydrologic cycle, is the continuous movement of water from the earth’s surface to the atmosphere and then back to the ground. It is a continuous process. Hence, it does not have a starting or an ending point.

What is water cycle for Class 4?

They are evaporation, condensation, precipitation and collection.

What is water cycle for Class 2nd?

The four main stages of the water cycle are evaporation, condensation, precipitation and runoff. Sun: the water cycle is driven by the energy from the sun warming the earth. Evaporation: the warmth of the sun causes water from lakes, rivers and oceans to evaporate and turn from a liquid to a gas.

Who discovered water cycle?

The first published thinker to assert that rainfall alone was sufficient for the maintenance of rivers was Bernard Palissy (1580 CE), who is often credited as the “discoverer” of the modern theory of the water cycle.

What is a water cycle Class 7?

The constant movement of water from the Earth to the atmosphere and back to the Earth through the process of evaporation, condensation and precipitation is known as the water cycle.

What is water made of kids?

We are all made of atoms stuck together (or, as scientists would say, “bonded”). Atoms bonded together form molecules. A molecule of pure water is made of two hydrogen atoms bonded to an oxygen atom.

Will we run out of water?

So it might appear that our planet may one day run out of water. Fortunately, that is not the case. Earth contains huge quantities of water in its oceans, lakes, rivers, the atmosphere, and believe it or not, in the rocks of the inner Earth.

Can water be man made?

Yes, it is possible to make water. Water is made of two hydrogen atoms and one oxygen atom. The process to combine hydrogen and oxygen is very dangerous though. Hydrogen is flammable and oxygen feeds flames, so the reaction to create water often results in an explosion.

Can u make water?

Theoretically, this is possible, but it would be an extremely dangerous process, too. To create water, oxygen and hydrogen atoms must be present. Mixing them together doesn’t help; you’re still left with just separate hydrogen and oxygen atoms.

Is Earth losing water?

Water flows endlessly between the ocean, atmosphere, and land. Earth’s water is finite, meaning that the amount of water in, on, and above our planet does not increase or decrease.

Will we run out of water in 2050?

Demand for water will have grown by 40% by 2050, and 25% of people will live in countries without enough access to clean water. This warning does not come as a surprise. The UN, and other global organizations, have been warning us of water shortages by 2050 for years — if not decades.

Is water wet?

Water is wet, in the sense of being a liquid which flows easily, because its viscosity is low, which is because its molecules are rather loosely joined together.

Is Lava wet?

If we’re using it as an adjective (definition: covered or saturated with water or another liquid), then lava is a liquid state so it therefore it’s wet. But nothing touched by lava is left damp or moist, which means that you can’t really use wet as a verb to describe lava.

Is fire burnt?

Can fire *be* burned? Though as a wall built partly of flammable material I wish fire could be burned, it can’t. Fire is just the light and heat resulting from oxidation of fuel; there is nothing in fire to oxidize, because fire itself isn’t a substance it’s a process.

Is a fire dry?

Water is wet, but fire is not dry. When you burn organic material, like wood or wax, all the hydrogens are converted into water, H2O. If you burn glucose, fully half of the volume of the gases produced is water vapor.
