In the troposphere, temperatures decrease with altitude (air pressure), which is known as the adiabatic lapse rate (9.8 Â°C per thousand feet). While there are different tempeâ¦ratures throughout the atmosphere, there are both increases and decreases in it as one moves upwards.
To easily shred romaine lettuce, stack several washed and dried leaves, roll up to form a cylinder and slice crosswise at 1/4- to 1/2-inch intervals. For best results, do not toss lettuce with dressing until just before serving as the dressing wilts the leaves.
