The trade winds prevail in the lower portion of the earth’s atmosphere, in the lower section of the troposphere.These winds become dry when they reach the western sides of the continents, and hence don’t bring any rain with them. As these regions become devoid of moisture, deserts are formed.Why Like That?The earth rotates on the East side. Moving air is deflected by the Earth’s rotation. ... Read More

An earthquake is defined as the sudden shaking of the Earth's surface. Earthquakes are caused by the collision of tectonic plates in the Earth's crust. These plates ride over each other when instability is created in the crust due to the release of energy from the Earth's core.There are large earthquakes and small earthquakes. Earthquakes are measured using an instrument called Seismometer. The magnitude of an earthquake is represented on the Richter scale. On the scale, 3 or less is scarcely noticeable, and magnitude 7 or more causes damage over a wide area.The Great Chilean earthquake also known as the ... Read More
