Questions Worksheet 

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.
