Final answer:
Landforms like mountains and plains are shaped by physical processes such as tectonic movements and erosion. Rolling hills in my area are formed by the uplift of land followed by weathering and erosion, leading to their smooth, rounded shapes.
Step-by-step explanation:
In geography, landforms are natural physical features of the Earth's surface, such as mountains, plains, and islands. These landforms are shaped by various physical processes including tectonic forces, erosion, weathering, and sedimentary processes. In my area, two types of landforms created by these geographical agents are the rolling hills, formed by a combination of erosional and tectonic activities, and river valleys, carved out by the persistent flow of rivers eroding the earth.
The formation of rolling hills, for example, often begins with tectonic forces pushing up land to create larger mountainous regions. Over time, erosion caused by wind, water, rain, ice, and the effects of temperature changes, combined with the process of weathering, breaks down these larger structures into gentler, undulating hills. The soil-building process also contributes to the development of these landforms by creating layers of soil that cover the hills and support vegetation.
