What is the process that converts liquid water on the ground into clouds?

What is the process that converts liquid water on the ground into clouds?

condensation

What is the order that rain or snow gets to the ocean?

Water drops form in clouds, and the drops then return to the ocean or land as precipitation – let’s say this time, it’s snow. The snow will fall to the ground, and eventually melts back into a liquid and runs off into a lake or river, which flows back into the ocean, where it starts the process again.

What is the process of water cycle?

The water cycle consists of three major processes: evaporation, condensation, and precipitation. Evaporation is the process of a liquid’s surface changing to a gas. In the water cycle, liquid water (in the ocean, lakes, or rivers) evaporates and becomes water vapor.

What is the main process by which water moves from land to the atmosphere *?

transpiration

Where is most of the water on Earth stored?

The ocean holds about 97 percent of the Earth’s water; the remaining three percent is found in glaciers and ice, below the ground, in rivers and lakes. Of the world’s total water supply of about 332 million cubic miles of water, about 97 percent is found in the ocean.

In what form can we see the water in the atmosphere?

The water in the atmosphere makes up only a very small percentage of the total water on Earth. In the atmosphere, water exists as a gas (water vapor from evaporation), as a liquid (droplets of rain and liquid water that coats solid particles), and as a solid (snow and ice). Its structure depends on its state.

What are 3 characteristics of the troposphere?

It contains three-quarters of the mass of the Earth’s atmosphere and is composed of 78% nitrogen, 21% oxygen, and a 1% mixture of argon, water vapor, and carbon dioxide. Air at the bottom of the troposphere or near the Earth’s surface is warmer, which means the higher the altitude, the colder it is.

What are the 7 layers of the Earth’s atmosphere?

The 7 Layers in Order

  • Exosphere.
  • Ionosphere.
  • Thermosphere.
  • Mesosphere.
  • Ozone Layer.
  • Stratosphere.
  • Troposphere.
  • Earth’s Surface.

Which layer of the atmosphere is the most important for us and why?

troposphere

Why is troposphere important for us Class 7?

Troposphere is the densest layer of atmosphere that is composed of water vapour, dust particles and many other impurities. Due to this thickness, troposphere absorbs most of the heat radiated by the Earth’s surface, thereby, maintaining the temperature of the surface.

What is the important of the atmosphere?

The atmosphere protects living things from the Sun’s most harmful rays. Gases reflect or absorb the strongest rays of sunlight (figure below). The atmosphere shields Earth from the most harmful solar rays.

How does troposphere support life?

The troposphere is the only atmospheric layer that can support life. The higher layers have filtered out the harmful radiation, and there are large amounts of water vapor. This is the layer where clouds develop, birds fly, and pollution collects. Yes, the troposphere is where humans most pollute the atmosphere.

What is an interesting fact about the troposphere?

The troposphere is made up of approximately 78% nitrogen, 21% oxygen, and 1% other gases, which include carbon dioxide, methane, neon, krypton, argon, helium, and hydrogen. The troposphere contains approximately 99% of the water vapour in the earth’s entire atmosphere.

Do we live in the troposphere?

We humans live in the troposphere, and nearly all weather occurs in this lowest layer. Most clouds appear here, mainly because 99% of the water vapor in the atmosphere is found in the troposphere. Air pressure drops, and temperatures get colder, as you climb higher in the troposphere.

Is the troposphere hot or cold?

Troposphere. The temperature of the troposphere is highest near the surface of the Earth and decreases with altitude. On average, the temperature gradient of the troposphere is 6.5°C per 1,000 m (3.6°F per 1,000 ft.) of altitude.

What happens to the temperature as you move up through the troposphere?

Temperatures drop as you move upward through the troposphere. Higher up in the troposphere, where less heat from the surface warms the air, the temperature drops. Typically, the temperature drops about 6.5° C with each increase in altitude of 1 kilometer (about 3.6° F per 1,000 feet).

Why the temperature decreases with altitude?

As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it’s snowing), the temperature decreases more slowly with height.

What is the temperature range for the troposphere?

As the density of the gases in this layer decrease with height, the air becomes thinner. Therefore, the temperature in the troposphere also decreases with height in response. As one climbs higher, the temperature drops from an average around 62°F (17°C) to -60°F (-51°C) at the tropopause.

Which activity does not contribute to global warming?

Reforestation is the activity among these four options that does not contribute to global warming. It is the act of planting more trees and restoring the forest and woodlands. It mitigates global warming by enhancing biological process thru reduction carbon dioxide, a greenhouse gas that affects global warming.

Which gas is the main cause of global warming?

carbon dioxide (CO2)
