Landform 2 is
Natural Arch
200
What is longshore drift
process of erosion and deposition where sand particles are moved form one part of a beach to another according to wind/tide and waves
300
What is Erosion:
Erosion: the wearing down of material by wind or water
300
What is the result of diverging plate boundaries
Rift valleys Mid-ocean ridges

On the map name 2 plates that are convergent

What is created when this sand is eroded away and washed to another part of the beach?
• When large numbers of sand particles are moved along a coastline, depositional features are formed called spits, bars and tombolos (deposition).
500
What is Pacific Ring of Fire
Pacific Ring of Fire: term given to describe the ring of tectonic activity, volcanoes and earthquakes around the boundary of the Pacific Plate.
500
What is the process which causes fold mountains
Mountains are formed by tectonic plates pressing together. As the pressure builds, the rocks compress/buckle and are forced upwards.
