Landforms of Rejuvenation. L.O.s. To understand what river rejuvenation is and the landforms that result from it . To practice cartographic skills using an OS map extract.  . 11. Landforms are the natural shapes or features of the land.. There are many different types of landforms found on Earth.. What are Landforms?. Mountain. A mountain is a place on Earth’s surface that is much higher than the land around it.. Tributary- small stream flowing onto a larger one. Drainage Basin- land where a river collects it’s water from- also called a water shed. Divide- land separating two drainage basin. Landforms Created by Erosion. Water Erosion. How Does Moving Water Cause Erosion?. Erosion by water begins with a splash of rain.. Some rainfall sinks into the ground.. Some evaporates or is taken up by plants.. The rest of the water runs off over the land surface.. The natural shapes or features on the Earth’s surface are called landforms.. Many different types of landforms can be found on the Earth – here are just a few examples:. Peninsula. Peninsula – a large piece of land that juts far out into the water and is almost surrounded by water.. Rivers have become regular features in the news. In any given year, one or more rivers become notorious for their devastating floods. But for most of the time, rivers are very useful – they provide people with their livelihoods, a place to live near and are a great source of recreation and leisure. Learning to live and cope with rivers would seem to be of increasing importance. And yet, many human activities seem to make the river environment, and the human use of it, more hazardous. Is it possible for humans to live harmoniously with rivers, while benefit from them at the same time?. A methodology for the analysis of permanent pastures landscape of Alto .

Formation of a Waterfall and Gorge. 2.. Formation of a Waterfall. A waterfall often occurs when a river flows from one rock type onto another. . For example, if the river flows from the harder rock and onto softer rocks because of the vertical movement of rocks along a fault line in the past.. Some intercepted by vegetation and evaporated. Amount of interception depends on plant structure. Some infiltrates permeable ground. Some blocked by impermeable surfaces. Infiltration. Depends. Physcial characteristics of soil. River erosion.
