GCSE Geography: UK's Evolving Physical Landscape

This video tutorial covers the formation of erosional features such as caves, arches, and stacks on headlands, characteristic of discordant coastlines. It explains the processes of hydraulic action and abrasion, and how sub-aerial processes contribute to the weakening and collapse of these formations. The video also distinguishes between concordant and discordant coastlines, highlighting the differences in rock formations and the resulting geographical features.

What is the main topic of the video?

• The UK's economic landscape

• The UK's evolving physical landscape

• The UK's cultural landscape

• The UK's political landscape

Which feature is NOT part of the cave, arch, and stack formation?

• Cave

• Arch

• Stack

• Bay

What is hydraulic action?

• Waves carrying particles that erode the rock

• Air in cracks being compressed by waves

• Plants growing on the cliff

• Rainfall weakening the cliff top

What is abrasion?

• Plants growing on the cliff

• Rainfall weakening the cliff top

• Waves carrying particles that erode the rock

• Air in cracks being compressed by waves

What forms when two caves meet in the middle of a headland?

• A cove

• An arch

• A bay

• A stack

What happens to the top of the arch over time?

• It becomes stronger

• It collapses

• It forms a cave

• It erodes into a bay

What is the final stage of the cave, arch, and stack formation?

• A cave

• An arch

• A stump

• A stack

What is a discordant coastline?

• Where only soft rock is present

• Where only hard rock is present

• Where rock types run at angles to the sea

• Where rock types run parallel to the sea

What feature is commonly found on a concordant coastline?

• Coves

• Bays

• Stacks

• Headlands

What type of rock is mentioned as being resistant in a concordant coastline?

• Granite

• Limestone

• Shale

• Sandstone
