Newton’s law of universal Gravitation states that a particle attracts every other particle in the universe using a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Gravitation Gravitation is the force by which every mass or particle of matter, including … Read more
Earth’s Rotation and Revolution Primarily two motions: Rotation and Revolution. Rotation of Earth Earth rotates along its axis from west to east. It takes approximately 24 hrs to complete on rotation. Days and nights occur due to rotation of the earth. The circle that divides the day from night on the globe is … Read more
Weather forecast There are two ways for weather forcasting: Short-range forecasting Meteorologists can make somewhat longer-term forecasts (those for 6, 12, 24, or even 48 hours) with considerable skill because they are able to measure and predict atmospheric conditions for large areas by computer. Using models that apply their accumulated expert knowledge quickly, accurately, and … Read more

Tides are periodic primarily because … Read more
Volcanoes and sea-scarps. This great variety of relief is largely due to interaction of tectonic, volcanic, erosional and depositional processes. At greater depths, the tectonic and volcanic phenomena are more significant processes. Continental Shelf: This is a gentle seaward sloping surface extending from the coasts toward s the open sea. In all, about 7.5% of … Read more
