Heights refer to the measurement of how tall something is from its base to its top. This can apply to various objects, such as buildings, mountains, or even people. Heights are typically measured in units like meters or feet, and they can vary greatly depending on the object in question. For example, the height of the Eiffel Tower is about 300 meters, while the height of an average adult human is around 1.7 meters. In geography, heights are often used to describe the elevation of landforms above sea level. Mountains, such as Mount Everest, are measured by their height to determine their prominence and rank among other peaks. Understanding heights is important in fields like architecture, aviation, and environmental science, as it helps in planning and assessing various projects and natural features.
