What is the most common rock found in Canada? Igneous rock (granite, gneiss) forms when molten rock cools. The Canadian Shield’s igneous base abounds in copper, gold, iron, and nickel. Sedimentary rock (sandstone, limestone) consists of hardened layers of rock particles. Beneath the Prairies, sedimentary layers store oil, gas, and coal. What are the major […]

What is the special of Science Day? National Science Day is celebrated in India on 28 February each year to mark the discovery of the Raman effect by Indian physicist Sir C. V. Raman on 28 February 1928. For his discovery, Sir C.V. Raman was awarded the Nobel Prize in Physics in 1930. What is […]

How fast does water carry heat away from the body? He went down so fast and never came up again.” Here’s how it can happen and what you can do about it. Cold water carries heat away from the body 25 times faster than air of the same temperature and as a result, the body […]

What are three main characteristics of an image? The three characteristics of […]

Which three factors affect soil formation? Scientists attribute soil formation to the following factors: Parent material, climate, biota (organisms), topography and time. How time affects soil formation? Weathering Over Time: As each plant community over time progressively modifies parent material, organic material builds up and topsoils form. The succession of plant communities above the ground […]

Is NH3 a dipole? NH3 is polar because it has 3 dipoles that do not cancel out. Each N-H bond is polar because N is more electronegative than H. NH3 is overall asymmetrical in its VSEPR shape, so the dipoles don’t cancel out and it is therefore polar. What is the weakest type of intermolecular […]

Why does oxygen attract electrons more strongly than hydrogen? The oxygen atom attracts the shared electrons more strongly than the hydrogen atoms do because the nucleus of the oxygen atom has more positively charged protons. As a result, the oxygen atom becomes slightly negative in charge, and the hydrogen atoms become slightly positive in charge. […]
