HIGHER GEOGRAPHY PHYSICAL REVISION

CARBONIFEROUS LIMESTONE SCENERY

Start describing how Karst features are formed by describing the erosion process CHEMICAL SOLUTION.

It is unlikely that you will be asked about the creation of the limestone itself.

Do not spend much time in a question explaining this.

Karst scenery features start withthe exposure of the rock to the elements, laterally by the glaciers.

You MUST be able to explain the basic chemistry of the erosion process- mention the PH quality of both rain AND rock!

Chemical formulae are not essential- but get them right if you use them!

Pavement, clints,grikes

Underground, overground, (Wombling free?)

The question asks you to explain the formation of upland limestone scnery.

Start above the limestone plateau on the uppermost impermeable rock layer. Describe its impermeability! (It has streams at the surface!)

Then tell the story of the river as it flows onto the limestone pavement- describe the limestone with its clints and grikes. Describe the features found at the surface like scars, dry valleys and shake-holes.

Do not describe yet the features caused by water erosion underground, like gorges.

Dry valley

Joints and bedding planes

Erratic

shakehole

slide5

HIGHER GEOGRAPHY PHYSICAL REVISION

The river finds a swallowhole and disappears underground. Why? Remind the reader about solution.

Describe where the calcium carbonate goes to when dissolved- INTO THE WATER !

Where does it come back OUT of solution?

IN THE CAVERN SYSTEMS !

slide6

HIGHER GEOGRAPHY PHYSICAL REVISION

This is poorly labelled!

Explain how the water gets into the cavern in the first place- joints !

Describe the formation of stalactites and stalagmites, with pillars and flowstones as added extras. Explain carefully how the CaCO2 gets out of the water and forms the features.

Remember the

benefit of a

well-labelled

diagram!

slide7

HIGHER GEOGRAPHY PHYSICAL REVISION

Continue the story of the river as it flows down inside the limestone through the passages and tunnels.

Tell how solution can create a limestone GORGE at the surface.

Explain where the water goes to once it reaches the base of the limestone plateau.- RE-EMERGENT STREAM or resurgence

HIGHER GEOGRAPHY PHYSICAL REVISION

COASTLINES- erosion features

Remember to detail the processes of erosion by the water- there are 6- can you remember them all?

What factors determine the amount of erosion?

corrosion

attrition

solution

hydraulic action

water-layer weathering

wave pounding

Fetch

Wave details

Weather details

Local geology

slide9

HIGHER GEOGRAPHY PHYSICAL REVISION

  • There are eight erosion-related features you need to learn up.
  • You need to be able to ;-
  • Describe them using their proper terms
  • Explain IN DETAIL how they form
  • Draw simple LABELLED SKETCHES of them
  • Give EXAMPLES of them in the UK.

BAY AND

HEADLAND

CAVE AND

BLOWHOLE

STACK

STUMP

ABRASION

NOTCHES

ARCH

NEEDLE

WAVE-CUT PLATFORM

Bay and headland formation

HIGHER GEOGRAPHY PHYSICAL REVISION

Sorted beach sediments

Transportation of eroded sediments is done by which process?

Explain how it works.

Why do the waves travel at an angle onto the beach?

What happens to the particles as they are transported?

Remember the

benefit of a

well-labelled

diagram!

WHAT WORLD-WIDE EVENT CAUSES THESE LAST THREE FEATURES?

How do these features form?

Do you know what these terms mean?
