How was the Scarborough Bluffs formed?
The bright white cliffs of Scarborough Bluffs are made of sediments like sand, silt, and clay that were washed into the Lake Ontario Basin prior to the arrival of the ice sheet, between 80,000 years ago and 20,000 years ago when the climate was slowly cooling.
Why is Scarborough Bluffs important?
The Scarborough Bluffs are a significant geological feature resulting from the accumulation of sedimentary deposits over 12,000 years ago. They were formed by the natural processes of wind and water erosion from Lake Ontario.
Why are the Scarborough Bluffs called Bluffs?

What are Bluffs and how are they formed?
A bluff is defined as a steep shoreline slope formed in sediment (loose material such as clay, sand, and gravel) that has three feet or more of vertical elevation just above the high tide line. Cliffs or slopes in bedrock (ledge) surfaces are not bluffs and are not subject to significant erosion in a century or more.

Why are the Scarborough Bluffs unstable?
The Bluffs are unstable due to several natural processes, including wave action from Lake Ontario, surface water runoff and over-steepening of the slope face to precipitation, wind, and freeze-thaw cycle. The Bluffs are affected by these natural processes all year long.
What caused Chimney Bluffs?
The bluffs are formed from eroded drumlins, teardrop-shaped hills of glacial till that were deposited and shaped by glaciers during the most recent ice age. The erosive power of wind, rain, snow, and waves has formed the landscape into sharp pinnacles.
What are Bluffs used for?
Purpose. BLUF is used for effective communication. It helps manage a reader’s load as most readers’ priority is to get through all text or copy quickly and efficiently. This way, the reader can grasp the main idea or the whole thought of a write-up fast.

What causes canyons to form?
The movement of rivers, the processes of weathering and erosion, and tectonic activity create canyons. The most familiar type of canyon is probably the river canyon. The water pressure of a river can cut deep into a river bed. Sediments from the river bed are carried downstream, creating a deep, narrow channel.
