What is difference between a plateau and a plain?
A plateau is a land area having a relatively level surface considerably raised above adjoining land on at least one side, and often cut by deep canyons. A plain is an area of land not significantly higher than adjacent areas and with relatively minor differences in elevation, commonly less than 500 ft. (150 m), within the area.
What is the physical interaction of Afghanistan?
Afghanistan is made of mostly rugged mountains and plains in north and southwestern plateau desert area for example Hindu Kush mountain range, Hazarajat. However Afghanistan also has fertile regions in the Northern plateau. Physical Features of Afghanistan have divided the country into three regions depending on its characteristics and wide landscapes.
Why is the kettle quiet just before the water boils?
When the water boils, the steam collects in the top part of the kettle. Then, the air above the water is saturated with steam. The boiling stops momentarily and the steam is then pushed out. As the steam is pushed out, it produces a whistling noise. ---- Early in the boiling process, the water has a very unequal distribution of heat. This causes small pockets of water (where the temperature is highest) to vaporize and produce small steam bubbles, and it's those small bubbles (as they release from the bottom of the pan, force their way up through the cooler water, and burst at the top) that set up tiny explosive vibrations that are picked up and amplified by the metal of the pot. As the water gets closer to boiling, though, the distribution of heat in the liquid begins to even out, and instead of forming small localized vapor bubbles, the hotter water at the bottom tends to rise as a whole while the cooler water at the top falls as a whole, producing a kind of rolling cell; water vapor is produced and released almost exclusively at the top of the liquid, so there are far fewer bubbles to explode and set up vibrations, hence less sound. ---- The boiling point of water depends on air pressure. A plateau about one and a half kilometers high will have a lower atmospheric pressure than at sea level. Thus, water will boil at a lower temperature at that high plateau. Now, that silence is due to almost reaching the required temperature to overcome the pressure and thus continue. It's like an energy absorption. The whistling: Many kettles are designed to make a whistling noise at boiling point so we can know when the water has boiled. It does not whistle before this because the water vapor coming out is not yet enough to make a noise.
What is the channel responsible for absolute refractory period?
Na+ channels influx (phase 0) then L-type Ca 2+ (slow calcium channels) to maintain the plateau (phase 2) then the first half of phase 3 - where voltage-gated and the delayed (iK1) k+ channels are starting to open and the Ca++ are starting to close. Phases 0-3.5 this is the absolute refractory period - PERIOD
How many kJ of heat are necessary to melt 32 grams of ice at -10 degree C and boil it all away as water vapor?
How many kJ of heat are necessary to melt 32 grams of ice at -10 °C and boil it all away as water vapor?Hint: Do this problem in steps! Four steps to be exact!You will need the following information:Specific heat capacity of ice (this is the slope of the first part of the graph below): 2.1 kJ/kg per °CLatent heat of melting (fusion) of ice (this is the length of the first plateau on the graph): 335 kJ/kg (note there is no temperature change associate with latent heat).Specific heat capacity of water (this is the next slope on the graph): 4.2 kJ/kg per °CLatent heat of vaporization of water (the final plateau on the graph): 2260 kJ/kg (note this is a huge number and again, the temperature does not increase as the water vaporizes).
What is the difference between Northern plain and Peninsular plateau?
The Northern Plain is a low-lying region formed by the depositional activity of rivers like the Ganges and Indus, characterized by fertile alluvial soil. The Peninsular Plateau is an elevated region made up of hard igneous and metamorphic rocks, with plateaus and hills like the Deccan Plateau. The Northern Plain is flatter and more agriculturally productive, while the Peninsular Plateau is older, more rugged, and mineral-rich.
What is normal ventilator plateau pressure?
The plateau pressure is the pressure applied (in positive pressure ventilation) to the small airways and alveoli. It is believed that control of the plateau pressure is important, as excessive stretch of alveoli has been implicated as the cause of ventilator induced lung injury. The peak pressure is the pressure measured by the ventilator in the major airways, and it strongly reflects airways resistance. For example, in acute severe asthma, there is a large gradient between the peak pressure (high) and the plateau pressure (normal). In pressure controlled ventilation, the pressure limit is (usually) the plateau pressure due to the dispersion of gas in inspiration. In volume control, the pressure measured (the PAW) by the ventilator is the peak airway pressure, which is really the pressure at the level of the major airways. To know the real airway pressure, the plateau pressure which is applied at alveolar level, the volume breath must be made to simulate a pressure breath. An inspiratory hold (0.5 to 1 second) is applied, and the airway pressure, from the initial peak, drops down to a plateau. The hold represents a position of no flow.
What is the difference between mountain pastoralists and plateau pastoralists?
one lives on a mountain, one on a plateau
What is the difference between a foothill and a plateau?
A foothill is the base of a mountain or a hill at the lower elevations, while a plateau is a flat-topped elevated landform with steep sides. Foothills are typically found at the base of mountains, gradually rising towards the mountains, while plateaus are typically high, flat areas that are elevated above surrounding land.
What is the difference between a plateau and a canyon?
A plateau is a flat highland. A Canyon is a valley formed by a river in an area where there is very low rainfall.
What difference between the plateau and basin?
A plateau is a high area with a flat top. A basin is a like a very large pot, a deep flat area.
What is the Difference between drainage pattern of the Indus System and of Baluchistan Plateau?
The drainage pattern of the Indus River system is dendritic, characterized by a network of small streams flowing into larger rivers. In contrast, the drainage pattern of the Baluchistan Plateau is mainly parallel, with rivers flowing roughly parallel to each other due to the topography of the region. Additionally, the Indus River system has a well-developed network of tributaries, while the rivers in the Baluchistan Plateau generally have fewer tributaries.
What is the difference of a plain and a plateau?
a plain is a flat land and a plateau is more raised
