astereotypedpattern and accompanied by altered breathing. Electrical stimulation of the main lifting muscle of the upper lip, thezygomatic major, with currents of varying intensity produces facial expressions ranging from the faint smile through the broad grin to the contortions typical of explosive ...
Movement of air by a fan or of water by a pump are examples of forced convection. More From Britannica fluid mechanics: Convection Atmospheric convection currents can be set up by local heating effects such as solar radiation (heating and rising) or contact with cold surface masses (cooling ...
Warm and cold currents in the world's oceans affect the climates of nearby coastal areas. For example, the warm Gulf Stream in the Atlantic Ocean warms the coast of northwestern Europe. Without the Gulf Stream, the climate of northwestern Europe would be more like that of the cold sub--...
Connotation is the idea or feeling a word carries, in addition to its literal meaning. Connotation is heavily dependent on a shared understanding of a hidden or implied meaning, so connotation can change from region to culture to language. Connotation Examples Let's look at some examples of con...
In short, hot fluids rise whilecold fluidssink. Unless an energy source is present (e.g.,sunlight, heat), convection currents continue only until a uniformtemperatureis reached. Scientists analyze the forces acting on a fluid to categorize and understand convection currents. These forces may inclu...
The component also depends upon the type of ecosystem. For example, Rainfall contributes to tropical rainforest ecosystems, sand in desert ecosystems and water, salinity, ocean currents, pressure in the marine ecosystem. All the factors are interrelated to each other. ...
like lichens and moss, will grow on the rocks and will become thepioneer species. Then, the site is next colonized by grasses and herbaceous plants. Soon, trees will grow on this site when their seeds reach the site, for example by wind currents or by bird droppings containing undigested...
She was sick of the cold winters and had tried to use her flying umbrella to cross the Atlantic. It was a catastrophe that nearly killed her. She was caught in gale-force winds that crash-landed her on a rocky beach in Scotland. Her “savior” tried to steal her umbrella. She beat ...
Thermal conduction happens whenever a cold material comes in contact with a warmer material. This happens when you put your hands on a cup containing a hot drink like coffee or tea. Heat is also conducted through the walls of a house if the inside and outside temperatures are not the same...
(a shard of glass) becomes smooth and beautiful only through years of being tossed about on the ocean's currents, it might over the course of the story come to be symbolic for the process of growing up or recovering from trauma—but not every reader will necessarily pick up on the ...
