Saharan dust on the car today. High air pressure; great for spring weather, even better for trapping pollutants!

[Geography Revision @ReviseGeography]

Shingle beaches tend to be steeper than sandy ones as shingle stacks better than sand. Steep beaches tend towards destructive waves

[Geography Revision @ReviseGeography]

Rocks that run parallel to the coast are concordant. Rocks that are perpendicular are discordant. The Isle of Purbeck has both

Mass movement is material moving downhill under the force of gravity. Mud flow, rockfall, landslide and rotational slip are egs

[Geography Revision @ReviseGeography]

Destructive waves have stronger backwash than swash, scour material, are higher in height and are more frequent.

[Geography Revision @ReviseGeography]

Constructive waves have stronger swash than backwash, deposit material, are lower in height, are less frequent and surge.

[Geography Revision @ReviseGeography]

Tides are caused by the gravitational pull of the moon or sun on our oceans. They are at their most extreme when s,m and e are in line

[Geography Revision @ReviseGeography]

Material is pulled back down the beach by backwash under gravity. Over time material moves down the coastline. Eastwards on the South coast

[Geography Revision @ReviseGeography]

Material is transported by longshore drift where waves push material up the beach (named swash) dependent on the angle the waves approach.

[Geography Revision @ReviseGeography]

Material is eroded at the coastline by abrasion, attrition, corrosion & hydraulic action. They all interact to create the landforms

And again, in front of the impressive intertidal mudflats at Spurn Point. Amazing day! #succession

Year 12s surveying the increased erosion south of Hornsea. #gloriousweather

[OGA Geography @OGAGeography]

Year 12 trip to Hornsea and Spurn Point tomorrow! Should be a good one!

Is wealth spread fairly across the globe? You decide!

Great day with AS/A2 students in a river! Can't decide whether it was wetter in or out of the river! #resilience ☔️🚿🏊

Today, all the Year 12s who went to Clapham made Mr Hedley incredibly proud to be your A level teacher. Amazing effort by all! :)
