Elevation refers to the height of a location above sea level. It helps us understand how high a place is in relation to the ocean, which is considered to be at zero elevation. For example, a mountain like Mount Everest has a very high elevation, making it one of the tallest points on Earth. Relief, on the other hand, describes the differences in elevation within a specific area. It shows how rugged or flat the land is. Areas with high relief have steep hills and valleys, while regions with low relief are more level. Understanding both elevation and relief is important for activities like hiking and urban planning.
