Emergent Coastlines typically have features such as rocky cliffs, sea stacks, and wave-cut platforms. These areas often experience uplift or a decrease in sea level, leading to the exposure of new land and the formation of these distinctive coastal landforms. Other indicators can include raised beaches and a lack of significant sediment accumulation.

How was coastal features of swanage bay formed?
The coastal features of Swanage Bay were formed through a combination of erosion and deposition processes. Erosion from the sea wearing away the softer rocks on the coastline and deposition of material, such as sand and pebbles, creating features like cliffs, beaches, and headlands over time. The unique geology of the area, including the presence of harder and softer rock layers, also contributes to the formation of specific coastal features in Swanage Bay.
Coastal Plains physical features?
Coastal plains are characterized by flat or gently undulating land that borders a coastline. They typically have low elevation and are vulnerable to flooding due to their proximity to the ocean. Coastal plains often consist of sandy beaches, salt marshes, and estuaries, and can support diverse ecosystems.
How do scientists typically classify landforms?
Scientists typically classify landforms based on their process of formation, such as erosion, deposition, or tectonic activity. They also consider the size, shape, and elevation of the landforms when categorizing them into groups like mountains, valleys, plains, plateaus, and coastal features. Understanding the geological processes that shape landforms helps scientists study Earth's history and predict future changes in the landscape.
What characteristics are used to classify landforms?
Landforms can be classified based on their shape, size, elevation, slope, and the processes that formed them. These characteristics can help differentiate between landforms such as mountains, valleys, plains, plateaus, and coastal features. Additionally, the geology, climate, and vegetation of an area can also play a role in classifying landforms.
What do sediments from rivers and coastal erosion form along the coastlines?
Sediments from rivers and coastal erosion can form features along coastlines such as beaches, sandbars, deltas, and barrier islands. These features are continually shaped by the action of water, currents, and tides, contributing to the dynamic nature of coastal environments.
