The earth composition
網頁On the real Earth, departures from the spherical shape and uniformity and the effect of rotation all cause g to vary over the planet's surface. For example, the average value of g is close to 980 centimetres per second per second, but values at sea level range from about 978 near the Equator to 983 at the poles. 網頁2024年10月25日 · Mud is a slimy or sticky mixture of soil or other fine-grained earth material and water.
