Uk Physical Geography

Question 1

Where is the prevailing wind direction in the uk?

Answer 1

Prevailing wind direction is in the south west of England so more long shore drift occurs there

Question 2

What is solution?

Answer 2

Solution is when dissolved particles are carried along with the flow

Question 3

What is mechanical weathering?

Answer 3

Mechanical weathering, the most common one is freeze thaw this is when water gets in cracks in the rock and freezes the water expands. When the ice melts the pieces of rock fall off

Question 4

Where was England glaciated up to?

Answer 4

England was glaciated from the north down to London, but the areas south of London were still frozen

Question 5

What are faults?

Answer 5

Larger cracks in rock which are exploited to create stacks,stumps,arches etc.

Question 6

What causes v shaped valleys?

Answer 6

Water erodes v shaped valleys between two mountainous areas

Question 7

What is traction?

Answer 7

Traction is the movement of boulder rolled along the coast by the waves

Question 8

What are joints?

Answer 8

Small cracks in rock

Question 9

What are coniferous trees?

Answer 9

Coniferous trees are evergreen with thin needles e.g pine, cedar and yew trees

Question 10

What are the characteristics of hard rock?

Answer 10

Hard rocks are impermeable are resistant to all types of weathering, form rugged platforms like headlands, wave cut platforms, caves, stacks, stumps and arches

Question 11

What is saltation?

Answer 11

Saltation is the movement of smaller sand and rock along the coast with the flow of the water

Question 12

What are the characteristics of soft rock?

Answer 12

Soft rock is susceptible to all types of weathering and form soft rock landscapes such as bays

Question 13

What is backwash?

Answer 13

Backwash is the destructive wave that caries sand and gravel at 90 degrees to the coast due to the force of gravity

Question 14

What is swash?

Answer 14

Swash is the constructive wave that moves sediment along the coast in the same angle

Question 15

How are u shaped valleys formed?

Answer 15

Since England underwent glaciation glacial processes formed u shaped valleys

Question 16

What are deciduous trees?

Answer 16

Deciduous trees are trees that drop leaves and grow dormant during winter (the UK is mainly deciduous trees). For example elm trees and maple trees

Question 17

What is biological weathering?

Answer 17

Biological weathering is the weathering due to living organisms e.g roots get in cracks of rock and as they grow the cracks get bigger.

Question 18

How is sediment transported?

Answer 18

Sediment is transported vis traction,saltation, suspension and solution

Question 19

What is chemical weathering?

Answer 19

Chemical weathering is when the makeup of the rock is changed e.g feldspar in granite becomes soft clay minerals and carried along by the flow. Calcium carbonate or limestone is weathered by carbonation whereby carbon dioxide in the air reacts with the limestone to make calcium bicarbonate which is carried away by the water as solution

Question 20

What is the difference between weathering and erosional processes?

Answer 20

Weathering occurs in situ whereas erosional process have to physically come into contact with water
