rift valley
continental shelf
seamount
mid ocean ridge
30s - Q5
Identify this topographical feature: B
seamount
mid ocean ridge
continental shelf
trench
30s - Q6
Which letter represents the DEEPEST and most DIFFICULT place for scientist to study
C: seamount
D: trench
B: mid-ocean ridge
A: continental shelf
30s - Q7
Which describes the feature in the middle of a mid-ocean ridge
trench
rift valley
seamount
mid ocean ridge
30s - Q8
Our planet is mostly water! So why do scientist claim that it is so important to conserve(save) water?
there is more water than scientist claim there is; there is not a water crisis
there is actually 97% water for us to drink
there is only 1% ready for us to drink, the rest is saltwater or locked in ice caps
there is actually 3% of freshwater on earth;so the crisis is not as bad as scientist claim
30s - Q9
The deeper I go into the ocean, what happens to salinity?
salinity increases
salinity stays the same
there is no salinity in the ocean
salinity decreases
30s - Q10
Which ocean feature do you think represents the area with the highest salinity?
right valley
trench
seamount
abyssal plain
30s - Q11
This feature formed from an underwater volcano
seamount
rift valley
continental shelf
mid ocean ridge
30s - Q12
The deeper I go into the ocean how does temperature change?
it gets hotter the deeper you go
there is no temperature in the ocean
the temperature stays the same
it gets colder the deeper you go
30s - Q13
The deeper I go into the ocean, how does density change?
the deeper I go the denser it gets
there is no density in the water
the deeper I go the less dense it gets
density does not change the deeper you go
30s - Q14
Compare density to temperature in the ocean
Cold water is dense and will sink. As the water warms up, it becomes less dense and will rise
Cold water is low density and will rise. As the water warms up, it becomes more dense and will rise
Warm water is low density and will sink. As the water warms up, it becomes more dense and will rise
There is not much of a change in density and temperature in the ocean
30s - Q15
Surface currents are affected by the rotation of Earth, and this is called the
neap tides
coriolis effect
wind
surface currents
