Which statement most accurately reflects the relationship between dewpoint temperature in moisture in Earths atmosphere quizlet?
Which statement most accurately reflects the relationship between dew-point temperature and moisture in Earth’s atmosphere? A high dew-point temperature indicates moist air.
What source of energy most directly fuels instability in Earth’s atmosphere?
Solar radiation is the main energy source for atmospheric heating. The atmosphere heats up when water vapor and other greenhouse gases in the troposphere absorb infrared radiation either directly from the sun or re-radiated from the earth’s surface.
Which processes provide the greatest amount of moisture to the atmosphere?
Studies have revealed that evaporation—the process by which water changes from a liquid to a gas—from oceans, seas, and other bodies of water (lakes, rivers, streams) provides nearly 90% of the moisture in our atmosphere. Most of the remaining 10% found in the atmosphere is released by plants through transpiration.
What is condensation explain briefly the process of condensation?
Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor. Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water. Dew Point.
What condition must exist for liquid moisture to collect on the outside surface of the evaporator?
Liquid must be heated to a temp at which particles throughout the liquid have enough kinetic energy to vaporize. What is vaporization? Conversion of a liquid to a gas or vapor. What is evaporation?
Which of the following changes raises relative humidity?
increasing water vapor content increases relative humidity. > Increasing temperature decreases relative humidity.
Under what conditions does fog caused by cooling form?
Advection fog forms when warm, moist air passes over a cool surface. This process is called advection, a scientific name describing the movement of fluid. In the atmosphere, the fluid is wind. When the moist, warm air makes contact with the cooler surface air, water vapor condenses to create fog.
How does relative humidity describe the moisture content in the air?
What does relative humidity describe about air? It describes how near the air is to saturation. … The lower the dew point, the lower the amount of moisture in the air.
How does air temperature change from Earth’s surface to the lower thermosphere?
Briefly describe how the air temperature changes from Earth’s surface to the lower thermosphere. … In the lower thermosphere, the temperature increases with height (another inversion) because the charged particles from the sun interact with atmospheric molecules and heat up the thermosphere.
Why do you think that moisture appeared on the can when the ice was added to it?
Why do you think the cup with the ice has bigger drops of water on the inside than the cup without ice? When the water vapor is cooled by the ice, the water molecules slow down more than in the cup without the ice. This allows their attractions to bring more molecules together to become liquid water.
How is latent heat an important source of atmospheric energy?
When the molecules return to a liquid state the latent heat is released as sensible heat (heat you can feel basically). It is important in the atmosphere because it is the primary factor involved in the formation of convective clouds and the stability/instability of the atmosphere.
Which is the most precise cause for the adiabatic cooling of a rising parcel of air in the atmosphere?
What is the most precise cause for the adiabatic cooling of a rising parcel of air in the atmosphere? A decrease in atmospheric pressure.
What are the causes and processes of changing atmospheric moisture?
Most clouds and precipitation are caused by cooling of moist air. … Cooling of moist air can also occur when warmer air interacts with cooler land or water. As moist air cools, water vapor can change into a liquid (water drops) through the process of condensation.
Which weather change usually occurs when the difference between the air temperature and the dewpoint is decreasing?
An increasing graph. Which weather change usually occurs when the difference between the air temperature and the dew-point temperature is decreasing? The relative humidity increases.
What steps of the water cycle cause rainy weather conditions use the terms evaporation condensation saturation and precipitation in your explanation?
The two steps in the water cycle that cause rainy weather conditions are condensation and precipitation. Condensation is when water vapor changes phase to become liquid water. One of the results of condensation can be clouds containing liquid water.
What are the 4 types of condensation?
Condensation | Forms of Condensation: Dew, Fog, Frost, Mist | Types of Clouds.
What happens to the water vapor when it reaches a cool atmosphere?
When water vapor in the air cools, the opposite of evaporation occurs: condensation. The condensation definition is water changing from a gas to a liquid. Condensation makes it possible for clouds to form. Clouds contain liquid water droplets and solid ice crystals.
How does temperature affect the amount of water observed on the outside of the glass?
Now the amount of water that can be dissolved in air is smaller when the temperature drops, so if you have a cup filled with something cold, the outside of the cup is at a low temperature; this chills the air that is adjacent to the cup and since the chilled air cannot keep the water dissolved in the air, the water …
What condition must occur in order for liquid to boil?
What condition must exist for a liquid to boil? When a liquid is heated to a temperature at which particles throughout the liquid have enough kinetic energy to vaporize, the liquid begins to boil.
What conditions must exist for a liquid boil?
Boiling. A liquid boils at a temperature at which its vapor pressure is equal to the pressure of the gas above it. The lower the pressure of a gas above a liquid, the lower the temperature at which the liquid will boil.
What is adiabatic cooling and heating?
In adiabatic heating and cooling there is no net transfer of mass or thermal exchange between the system (e.g., volume of air) the external or surrounding environment. … Compression of the air mass is accompanied by an increase in temperature. Because warmer air is less dense than cooler air, warmer air rises.
Why does the adiabatic rate of cooling changes when condensation begins Why is the wet adiabatic rate not a constant figure?
Why is the wet adiabatic rate not a constant figure? The rate changes because of the addition of latent heat. Since the amount of condensation varies, so will the amount of latent heat released. Thus, the wet adiabatic rate is variable.
What is atmosphere moisture?
There is a continuous exchange of water vapor between the atmosphere and dead wildland fuels. … Dry fuels absorb moisture from a humid atmosphere and give up their moisture to dry air.
Which condition would most likely result in fog?
Frontal passage fog can occur in a number of situations: when warm and cold air masses, each near saturation, are mixed by very light winds in the frontal zone; when relatively warm air is suddenly cooled over moist ground with the passage of a well marked precipitation cold front; and in low-latitude summer, where …
What occurs when warm air is forced up and over a mass of cooler air?
On the other hand, when a cold air mass catches up with a warm air mass, the cold air slides under the warm air and pushes it upward. As it rises, the warm air cools rapidly. This configuration, called a cold front, gives rise to cumulonimbus clouds, often associated with heavy precipitation and storms.
Which condition would most likely produce fog?
Fog is most likely to occur at night or near dawn when the temperature of the day is normally at it’s lowest. The cool ground air forms fog and dew as the air-cools and water vapors condense into tiny droplets of water.
Does relative humidity increase with temperature?
Relative humidity changes when temperatures change. Because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air.
How does humidity affect weather conditions?
People rely on the air to help our sweat evaporate, which thus helps cool us down in hot weather. High levels of humidity stop our sweat from being able to evaporate, and therefore we feel much hotter than we might otherwise at that temperature.
How does humidity change with temperature?
As air temperature increases, air can hold more water molecules, and its relative humidity decreases. When temperatures drop, relative humidity increases. … Temperature therefore directly relates to the amount of moisture the atmosphere can hold.
