How does the water that evaporates get back to Earth in the water cycle?
Once evaporated, a molecule of water vapor spends about ten days in the air. As water vapor rises higher in the atmosphere, it begins to cool back down. When it is cool enough, the water vapor condenses and returns to liquid water. These water droplets eventually gather to form clouds and precipitation.
What are the three ways that water goes back into the atmosphere where does most of the water in the atmosphere come from?
Together, evaporation, transpiration, and sublimation, plus volcanic emissions, account for almost all the water vapor in the atmosphere that isn’t inserted through human activities.
Does water ever leave the earth?
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. Water, as a vapor in our atmosphere, could potentially escape into space from Earth. But the water doesn’t escape because certain regions of the atmosphere are extremely cold.
What are two ways that water is put back into the atmosphere?
The water may be taken up by plants and returned to the atmosphere through processes like transpiration and photosynthesis. Water may also be returned to the atmosphere through the combustion of plants in fossil fuel.
What would happen if we did not have air and water transport?
Every living thing on earth would die, since water is a large component of all known living cells, every plant, animal, fungus, etc would all dessicate completely, and crumble to dust. With all water vapor gone from the atmosphere, the sky might change color, and become a reddish tint due to the high oxygen content.
What other things will be affected if there is no water?
Without enough water, systems in your body will change. Your cells will shrink without enough water. Your brain will signal your body to urinate less. This will occur through your kidneys.
What will happen if there is no air on the Earth?
Organisms that need air to breathe would die. Plants and land animals would die. Fish would die. However, some bacteria could survive, so losing the atmosphere wouldn’t kill all life on Earth.
What causes the weight of the atmosphere?
Atmospheric pressure is caused by the gravitational attraction of the planet on the atmospheric gases above the surface and is a function of the mass of the planet, the radius of the surface, and the amount and composition of the gases and their vertical distribution in the atmosphere.
Is there more air than water on Earth?
So there is 500+ times more water than air… and 4000+ times more “land” than water. Or in percents, the mass is: Land: 99.98%
How does the atmosphere contribute to the water cycle?
Downloadable Water Cycle Products (coming soon!) The atmosphere is the superhighway in the sky that moves water everywhere over the Earth. Water at the Earth’s surface evaporates into water vapor which rises up into the sky to become part of a cloud which will float off with the winds, eventually releasing water back to Earth as precipitation.
How does water move in the water cycle?
It can move in the form of liquid, solid, or vapor. This complicated movement of the Earth’s water is called the water cycle. One of the most important “loops” in the water cycle involves evaporation of water from the ocean surface, transport in the form of water vapor to the continents by winds, and precipitation as rain or snow on the continents.
How is water released from the earth’s surface?
Water at the Earth’s surface evaporates into water vapor which rises up into the sky to become part of a cloud which will float off with the winds, eventually releasing water back to Earth as precipitation. Note: This section of the Water Science School discusses the Earth’s “natural” water cycle without human interference.
What is the name of the earth’s water cycle?
What is the Earth’s “water cycle?”. The water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth.
