how stable the coastline is over a few decades changes at the coastline relative to sea level how unstable the coastline is over a few months changes at the coastline relative to the frequency of storms
submergence of the shore by a rise in sea level depression of the land by the addition of glacial ice tectonic uplift of the land causes sea cliffs to develop uplift of the land by uplift after the retreat of glacial ice
Indicate the best description for the process occuring at each label in the photograph of an emergent coastline.
For each item below, use the pull-down menu to select the letter that labels the correct part of the image.
Which type of coast is this and why? [Hint]
submergent – the estuaries formed as the mouth of river systems near the shore were submerged by a rise in sea level emergent – the estuaries formed by uplift of the land by tectonic forces emergent – the estuaries formed as the mouth of river systems near the shore were submerged by a lowering of sea level submergent – the estuaries formed as the land was slowing subsiding under its own weight of increased sand arrival at the shore
the rate of glacial rebound is less than the rate of sea level rise the rate of tectonic uplift exceeds the rate of sea level fall the rate of glacial rebound exceeds the rate of sea level rise the tectonic subsidence rate exceeds the rate of sea level rise
where unconsolidated sediment is being rapidly eroded as sea level rises where bedrock is vigorously eroded as sea level rises where a bedrock, wave-cut cliff is rapidly retreating inland as sea level falls where unconsolidated sediment is being eroded as sea level falls
