Tides

Question 1

Overview

Answer 1

Regular and consistent inputs of energy

UK experiences 2 high and 2 low tides each day

Question 2

The moon

Answer 2

Moon has greatest influence, pulls water towards it creating a high tide

Compensatory bulge on opposite side
In areas between the 2 bulges its the low tide

Question 3

Spring tides

Answer 3

When Earth, moon and sun are aligned the gravitational pull is strongest 
High tides become higher 
Low tides lower
Creates larger tidal range 
Happens 2x a month

Question 4

Neap tides

Answer 4

Earth, moon and sun form a right angle this lessens gravitational pull

High tides lower
Low tides higher
Smaller tidal range

Question 5

Factors influencing tides

Answer 5

Morphology of seabed
Proximity of land masses

Coriolis force (spin of Earth)
Eg at equator there is no Coriolis force so around the world tidal range differs

Question 6

Small tidal range

Answer 6

Power of waves concentrated on narrow part of coastline for long period of time such as cliff base
Creates features such as wave cut notch

Question 7

Large tidal range

Answer 7

Power of waves is spread out means the zone of erosion is wide
Waves will break out on specific part for short period of time

Question 8

High tidal range

Answer 8

create powerful currents as tides rise and fall
Found in spring tides
Important transfer mechanisms in transporting sediment as an output
