What is the difference between synoptic and prognostic charts? 2. How are prognostic charts different from synoptic weather maps? Prognostic charts are computer generated forecast showing the expected pressure pattern at a specific future time. Synoptic weather maps describe the state of the atmosphere over a large area at a given moment. What is good […]

What are the 5 steps of the hydrologic cycle? Student Features. Many processes work together to keep Earth’s water moving in a cycle. There are five processes at work in the hydrologic cycle: condensation, precipitation, infiltration, runoff, and evapotranspiration. These occur simultaneously and, except for precipitation, continuously. Why is hydrologic cycle important? The hydrologic cycle […]

What happens when a solid is dissolved in a liquid? In the simplest case it involves mixing two materials together. The most common examples of dissolving involve a solid and a liquid, usually water. When a solid dissolves the solid (solute) and the liquid (solvent) form a very close intimate mixture called a solution. Why […]

What happens if a hairline fracture is untreated? When a bone fracture is untreated, it can result in either a nonunion or a delayed union. In the former case, the bone doesn’t heal at all, which means that it will remain broken. As a result, swelling, tenderness, and pain will continue to worsen over time. […]

How do I combine two plots in R? Combining Plots R makes it easy to combine multiple plots into one overall graph, using either the. With the par( ) function, you can include the option mfrow=c(nrows, ncols) to create a matrix of nrows x ncols plots that are filled in by row. The layout( ) […]

What is the difference between control variable and independent variable? Independent variable – the variable that is altered during a scientific experiment. Controlled variable – a variable that is kept the same during a scientific experiment. Any change in a controlled variable would invalidate the results. What is the different types of variables? Parts of […]

What is the distance between two contour lines called? The elevation difference between two adjacent contour lines is called the contour interval (CI). Usually the contour interval is noted on the map legend. In most topographic maps every 5th contour line is drawn in bold print or wider than other contours. Such lines are called […]

What is indicator in simple words? : a substance (as a dye) used to show visually (as by a change in color) the condition of a solution with respect to the presence of a particular material (as a free acid or alkali) litmus and phenolphthalein are acid-base indicators. More from Merriam-Webster on indicator. What is […]

What are two examples of colloids? Examples of colloid are mayonnaise, milk, butter, gelatin, jelly, muddy water. What are the 4 types of colloids? The types of colloids includes sol, emulsion, foam, and aerosol. Sol is a colloidal suspension with solid particles in a liquid. Emulsion is between two liquids. Foam is formed when many […]

What causes neon to glow? Neon lighting consists of brightly glowing, electrified glass tubes or bulbs that contain rarefied neon or other gases. A high potential of several thousand volts applied to the electrodes ionizes the gas in the tube, causing it to emit colored light. The color of the light depends on the gas […]
