Scavenger Hunt 

Fact Card#1: How does water move on the surface of the ocean?  Water in the ocean is constantly moving. On the surface, water moves in from the waves

Fact Card#2: How does water move below the surface of the ocean? The water in the ocean is constantly moving. below, the surface the water moves great corrent  
 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. Ocean currents are moving screens with water within the ocean .
 Fact Card #5: Define the ‘surface current’. 
The surface current is when the current moves on or near the surface of the ocean.
Fact Card #6: List the factors which control the surface currents. 
Three factors that control the surface currents are Air currents earth, rotation and location of continents .
Fact Card#7: Which factors affect the flow of ocean surface water? 
Global wind belts are a major factor affecting the flow of the ocean surface water. 

Fact Card#8: How are deep currents generated in the ocean? Deep currents: Defence in the water temperature gradient moves the water and creates the deep currents.

Fact Card#9: Write down the characteristics of cold and warm water. Cold water is more dense and it sinks and moon warm water is less dense and it rises up .

Fact Card #10: Which ocean currents travel faster? Surface currents move faster than much faster than deep ocean currents.
Fact Card #11: Write the factors that cause the deep currents. Deep ocean currents are caused by changes in the temperatures, salinity, and  density of the water .

Card #12: How do the Sun and the Moon cause the ocean 
It causes the ocean from the gravitational pull between the sun and the earth, From the gravitational pull between the moon and the earth

Fact Card #13: Give the definition of wave. 
A wave is a rhythmic movement that carries energy through matter or space.

Fact Card#14: What are the causes of waves? 
The cause of waves are wind, earthquakes and gravitational forces of the moon and the sun 
Fact Card#15: List the characteristics of a wave. A charistic of a wave is the wavelength,wave height and the crest.

Fact Card#16: Write the parameters on which the wave height is Dependent.The height of the wave depends on  wind speed,distance over which the wind blows, length of time(fetch) the wind blows.
Fact Card #17: What happens during tide? 
Tides are periodic rise and fall of the sea level under the gravitational pull of the sun and the moon.
Fact Card #18: What do you mean by high tide? High tide is when water levels are at their 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 up into a slight Bulge on the side of the earth facing the moon. 
Fact Card#21: What is the cycle duration of high/low tide? Generally one low tide/ high tide cycle takes at every 12 hours and 25 minutes 
Fact Card#22: Define tidal range. The difference in the ocean level between high tide and low tide is called tidal change.
Fact Card#23: When does spring tide occur? 
Spring tides occur when the earth,the sun and the moon are in line.
 Fact Card #24: Which tides occur during a full/new moon? 
Spring tides occur during the full moon in the new moon.
Fact Card #25: When does neap tide occur? Neap tides occur when the moon and the sun are perpendicular to each other.
Fact Card #26: Which tides occur during the quarter moon? 
During a quarter moon and neap tide occurs 
Fact Card #27: Which tides are known as weak tides? Why?  Weak tides are also non as Neap tides. They are weak tides because Gravitational forces of the moon and the sun counteract  each other, creating weaker tidal forces. 
Fact Card#28: Which tides are known as strong tides? Why? Spring tides are known as strong tides because of the moon in the sun's Gravity Force combined to create a strong tide.
