What is a Sand Dune: Formation and Types of Sand Dunes

Sand dunes are some of nature’s most scintillating creations. These eye-catching land masses are found around the globe in different climatic conditions. They are not only limited to deserts, but can form in any landscape on the earth’s surface provided the conditions are right. Every sand dune is formed as a result of the interaction …

What is Ecological Succession?

Succession is a series of progressive changes in the composition of an ecological community over time. Succession is directional. Different stages in a particular habitat succession can usually be accurately predicted. Ecological successions are the noticeable changes that occur in an ecological setup over time. These changes are often predictable and take place in an …

What is Coriolis Effect and How it Affects Global Wind Patterns

‘Coriolis effect’ or Coriolis force can be defined simply as deflection of wind. Winds and ocean currents are in constant motion. This movement does not follow a straight line but bends and curves. This is the Coriolis effect which is noticeable in the curvature of global winds, and all that is free flowing across the …

What are the Winds, How Do They Form and Types of Winds?

Wind can be defined as air currents or moving mass of air from high-pressure areas to low-pressure areas. Typically, air under high pressure normally moves towards areas under low pressure. Thus, the greater the pressure difference, the faster the flow of air which creates moving air with a considerably strong force. The bulk movement of …

What are Hurricanes and How do Hurricanes Form?

Hurricane is a severe tropical cyclone – rapid inward circulation of air masses about a low pressure centre, usually with heavy rains and winds moving at 73 to 136 knots (miles per hour) forming over the Atlantic Ocean or Eastern Pacific Ocean. Hurricanes are witnessed as massive storms during powerful rains with strong winds, lightning, and …
