Day in the Salt Marsh, A
- Math Word Problems
1.
The distance between the high tide and the low tide in the Bay of Fundy in Canada is 40 feet. The difference in high tide and low tide in a local bay is only 3 feet. What is the difference between the sizes of the tide variances in the two locations?
43 feet
37 feet
40.3 feet
2.
How many hours are there in a day?
12
24
48
3.
If an average tide cycle takes approximately 12 hours to go from low tide, through high tide, and back to low, then one can assume that
If high tide is at 2:00pm, the next high tide will be about 2 in the morning
If high tide is at 2:00pm, the low tide will be around 8 that evening
both of the above
4.
If tides get lower by approximately 50 minutes later each day and low tide is at 2
low tide should be about 1:10 the next day
low tide should be about 2:50 the next day
low tide should be about 2:00 the next day
5.
If I am at the beach in the morning and low tide was at 8:00
the tide is going out (ebbing)
the tide is coming in (flooding)
not enough information to know
6.
If I am at the beach in the morning and low tide was at 8
high tide will be about twelve hours later than low
high tide will be about six hours later than low
high tide will be about four hours later than low
7.
Most areas have how many tide cycles each day?
3
4
2
8.
Tides are related to the moon phase. If high tide falls in the morning (about 8:00)
If high tide is in the morning on one Monday, then it will be low tide in the morning a week later.
If high tide is in the morning on Monday, it will be high tide in the morning the following Friday.
Not enough information to determine
9.
If it takes approximately 6 hours to go from high tide to low tide and vice versus, then slack tide (when tide is neither coming in nor going out) is approximately
Every 12 hours
Every 6 hours
Every 3 hours
10.
In a salt marsh by a river and the ocean, the ebb tide (going out) will be stronger than the flood tide (coming in) because it has the river flow adding to the tide. If the strongest tidal current is approximately 3 hours after slack, then
The strongest movement of water is at either high tide or low tide.
The strongest movement of water is three hours after high tide.
The strongest movement of water is three hours after low tide.
