WALT: Under Stand The Earth's Systems.
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 moves in currents.
Fact Card #3: What are the two types of ocean currents?
Surface currents and deep currents.
Fact Card #4: Define ocean currents.
Ocean currents are moving streams of water.
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.
Air currents, earth's rotation and location of continents.
Fact Card#7: Which factors affect the flow of ocean surface
water?
Global wind belts

Questions Worksheet
Fact Card#8: How are deep currents generated in ocean?
Difference in the water density due to the temperature
gradient.
Fact Card#9: Write down the characteristics of cold and
warm water.
Cold water is more dense and warm water is less dense.
Fact Card #10: Which ocean currents travel faster?
Surface currents travel much faster Then deep ocean
currents.
Fact Card #11: Write the factors that cause the deep
currents.
Deep currents are caused by the temperature, salinity
and the density of the water.
Fact Card #12: How do the Sun and the Moon cause the
ocean currents?
From the gravitational pull of the sun and moon Which also
causes currents.
Fact Card #13: Give the definition of wave.
A wave is a rhythmic movement that can that carries
energy through the matter or space
Fact Card#14: What are the causes of waves?
Waves are caused by wind earthquakes and the gravity
of the moon and sun. buy

Questions Worksheet
Fact Card#15: List the characteristics of a wave.
Wavelength, way fight, crest and Trough
Fact Card#16: Write the parameters on which the wave
height is dependent.
Wind speed distance over which the wind blows the
length of time (fetch) the wind blows.
Fact Card #17: What happens during tide?
Tired as a periodic rise and fall of the sea level under the
gravitational pull of the sun and moon.
Fact Card #18: What do you mean by high tide?
High tide is where the water is at its highest.
Fact Card #19: What do you mean by low tide?
Low tide is when the water is at its lowest.
Fact Card #20: How does the Moon’s gravity pulls ocean
water?
The moon's gravity pulls the water on the earth towards
it and the water moves up into bulge.
Fact Card#21: What is the cycle duration of high/low tide?
Generally 1 high tide or low tide cycle happens every 12
hours.

Fact Card#22: Define tidal range.
The difference in ocean level between high tide and low tide.
Fact Card#23: When does spring tide occur?
Spring tides happen when the Earth the sun and the moon
are in a line.
Fact Card #24: Which tides occur during full/new moon?
Spring tides occur during new the moon and the full moon
in the new moon
Fact Card #25: When does neap tide occur?
Neap tides happen when the moon and sun are
perpendicular to each other
Fact Card #26: Which tides occur during quarter moon?
Neap tide
Fact Card #27: Which tides are known as weak tides? Why?
Neap tides are weak because the moon and the sun pull
The water and make it weaker.
Fact Card#28: Which tides are known as strong tides? Why?
Spring tides are strong tides because the moon and the
sun's gravitational force combined to create a strong tide.
