Questions Worksheet 

Fact Card#1: How does water move on the
surface of ocean? 

Water moves in the form of waves

Fact Card#2: How does water move below
the surface of ocean? 

The water in the ocean is constantly moving
no matter what, water moves and great currents
and is one of the strongest forces in the world

 Fact Card #3: What are the two types of ocean
currents? There are two types of currents, surface
currents and deep currents

Fact Card #4: Define ocean currents. 

Moving streams of water in the ocean

Fact Card #5: Define the ‘surface current’. A
surface current is a current that moves on or
near the surface of the ocean

Fact Card #6: List the factors which control the
surface currents. 

the air currents, earths rotation and location of continents 

Fact Card#7: Which factors affect the flow of
ocean surface water? 

global wind is affecting the ocean flow 

Questions Worksheet 

Fact Card#8: How are deep currents generated
in ocean? Different the difference in the water
density due to the temperature gradients move
the water and creates deep current

Fact Card#9: Write down the characteristics of cold
and warm water. 

Cold cold water is more dense warm water is less
dense and it rises up 

Fact Card #10: Which ocean currents travel faster

surface currents travel much faster

Fact Card #11: Write the factors that cause the
deep currents. 

Deep ocean currents and caused by changes
in the temperature salinity NZ density of the water

Facts Card #12: How do the Sun and the Moon
cause the ocean The gravitational pull between
the sun and moon

Fact Card #13: Give the definition of wave. 

Away is a rheumatic movement that carries energy
through matter of space 

Fact Card#14: What are the causes of waves? 

Waves can be caused by the wind earthquakes or
gravitational Force  by the moon and sun

Fact Card#15: List the characteristics of a wave. 

The characteristics of a wave are the wave length
wave and wave height 

Fact Card#16: Write the parameters on which the wave 

height is 

Distance depends on when speed distance over
which the wind blows, length of time the wind blows. 

Fact Card #17: What happens during tide? 

the sea level rises and falls 

Fact Card #18: What do you mean by high tide?
High tide is a tide that is at it's very highest_ 

Fact Card #19: What do you mean by low tide? 

A low tide is the sea level that is at its lowest

Fact Card #20: How does the Moon’s gravity pull
ocean water? 

The moon's gravity pulls the water on the earth
towards it. the water moves into a slight Bulge
on the side of the earth that faces the moon. is
the is the sea level

Fact Card#21: What is the cycle duration of high/low tide? 

low tide / high tide table at every 12 hours and 25 minutes

Fact Card#22: Define tidal range. 

The difference between an ocean level
between the high tide and low tide is called a tidal range

Fact Card#23: When does spring tide occur? 

When spring tides occur when the Earth,
Sun and Moon are in a line 

 Fact Card #24: Which tides occur during a full/new moon?

Spring tides occur during the full moon and the new moon 

Fact Card #25: When does neap tide occur? 

when the sun and moon are perpendicular

 Fact Card #26: Which tides occur during the quarter moon? 

The tides that are caused during the quarter
moon is a neap tide

Fact Card #27: Which tides are known as weak tides? Why? 

Neap tides Because of the moon and sun counteract 

Fact Card#28: Which tides are known as strong tides? Why? 

Spring tides because the moon and the Sons
of gravitational force combined create an
extremely strong tide
