Which of the following reservoirs typically has the longest residence time for water molecules?
The largest store (oceans) have the longest residence time for water molecules.
What is residence time quizlet?
Residence time is the average length of time for a substance in a reservoir to be completely replaced. Substances having a short residence time in a reservoir are cycled into and out of the reservoir at a relatively fast rate. Another related term applied to reservoirs is turnover rate.
Which of the following has the longest residence time?
The residence time in lakes and glaciers varies between 20 and 100 years, but the longest residence times are in the ocean (3,200 years) and in the groundwater (up to 10,000 years).
Which of the following has the longest residence time in the atmosphere?
Nitrous oxide has a long residence time in the atmosphere, an average of about 120 years.
What is residence time science?
Residence time – is the average amount of time a substance spends in a particular compartment or reservoir. It is defined numerically as the steady-state amount of material in a reservoir divided by its total rate of inflow (or outflow).
What does residence time mean?
Residence time is defined as the amount of water in a reservoir divided by either the rate of addition of water to the reservoir or the rate of loss from it.
Which of the following has the smallest residence time?
The shortest residence time , 11 days, is for water vapour in the atmosphere, which is continually renewed by evaporation from the oceans and the land, and is lost by precipitation .
Which source has the widest range of residence time?
Underground water source has the widest range of residence time. Underground water are usually present deep under the ground and are formed from the rainfall seeping into the soil and remaining there. Evaporation takes a bit of the water and the remaining are usually present for a very long time.
Which greenhouse gases have the longest residence time?
Major Long-Lived Greenhouse Gases and Their Characteristics
| Greenhouse gas | Average lifetime in the atmosphere | 100-year global warming potential |
|---|---|---|
| Methane | 12.4 years** | 28–36 |
| Nitrous oxide | 121 years** | 265–298 |
| Fluorinated gases | A few weeks to thousands of years | Varies (the highest is sulfur hexafluoride at 23,500) |
Which carbon reservoir has the longest residence time quizlet?
Which of the following carbon reservoirs has the longest residence time: plants, the oceans, or sedimentary limestone? Sedimentary limestone, because a carbon atom may spend millions of years in the sedimentary/metamorphic rock reservoir, while it spends a short time (years to millennia) in the other reservoirs.
Which sources have the longest average residence time?
What is residence time in geography?
