Q

What is wave refraction?

A

As waves approach a coast they are refracted so that their energy is concentrated around headlands but reduced around bays

16
Q

What is mechanical/physical weathering?

A

geological process of rocks breaking apart without changing their chemical composition

17
Q

What is deposition?

A

Where water dumps and leaves behind the material it has been carrying

18
Q

What is solution(transport)?

A

Dissolved minerals within water

19
Q

What is saltation?

A

Small stones (1.0 – 99.99mm) bounced along river/sea bed

20
Q

What is suspension?

A

Very small particles of sand and silt (0.001-0.99mm) carried in the flow of water

21
Q

What is traction?

A

Large stones and boulders (>100mm) rolled along river/sea bed

22
Q

What is solution(erosion)?

A

Some minerals, such as calcium carbonate in limestone, and chalk slowly dissolve in water which is slightly acidic

23
Q

What is Attrition?

A

load carried by water collides into each other and rubs against each other, breaking the rocks up into smaller and smaller pieces. These pieces become smaller and rounder as rough edges are worn away.

24
Q

What is abraion/corrasion?

A

Where material carried by the water rubs against a surface which wears the material away

25
Q

What is Hydraulic Action?

A

Hydraulic action is when the force of the water compresses air into any cracks. The air expands explosively outwards as the pressure is released by the receding water. This removes fine material and enlarges cracks.

26
Q

What is freeze-thaw weathering?

A

when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart

27
Q

What is a landscape?

A

All the visble features of an area of land, natural and man-made

28
Q

What is an Upland?

A

Elevated areas of land including hills and mountains (often above 600m)

29
Q

What is a lowland?

A

flat, rolling landscapes, close to sea level and lie below 200m

30
Q

What is igneous rock?

A

Produced when magma cools, either beneath the ground or above the surface

31
Q

What is metamorphic rock?

A

Action of heat and pressure changes the existing rock to form a new structure and rock

32
Q

What is sedimentary rock?

A

Made form skeletons or marine organisms (coccoliths) and other sediments, laid down and compacted at the bottom of the ocean
